While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

Explains Quigley, “At the point of injection molding, the preform is in a molten state. This ‘melt-melt’ interface allows polymer chains and fibers to cross the bond line, resulting in an extremely strong and stable bond between the organosheet preform and the overmolded functional elements.” He adds: “We are already achieving cycle times today of under two minutes. This is the key to realizing the costs per unit demanded by the automotive industry.”

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Surface and sub-surface porosities are particularly critical for mould and die applications, as they may emerge on the part cavity walls after their subsequent machining, leading to defects on the moulded product; moreover, they may be greatly detrimental for the lifetime of the mould/die, constantly undergoing thermal fatigue while being in operation. Thanks to a finely tuned laminar argon flow, the DMP Flex 350 ensures a high removal rate of fumes which are the main driver of inconsistent density (Fig. 12).

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

In the composite overmolding cell, a six-axis robot places organosheet blanks in an IR oven (right) and then in the press for preforming and overmolding.

CCP Gransden knows composites—since the 1960s it has established itself in thermoset RTM, vacuum infusion, and filament winding. In 2012, the company saw new opportunities for growth in thermoplastic composites. Today, it offers press forming and compression molding of TP composites, along with its newest technology—injection overmolding of TP prepregs.

A specialist in thermoset composites since the 1960s, CCP Gransden is a relative newcomer to thermoplastic composites and to injection molding. Its exploration of organosheet overmolding has opened up new potential.

Considering that this case represents just one application, and that TK Mold can use this technology for many moulds and produce them at multiple locations at the same time, AM is very quickly paying for itself. As a result, TK Mold is now operating its AM machine at a very high capacity, in order to meet the demand for various optimised inserts.

With user-defined threshold values, this referencing process offers exceptional repeatability and accuracy without any risk of human error. Furthermore, the use of the laser enables the referencing of multiple parts on the same build platform in a single operation, further accelerating high-volume production. Thanks to this optical system’s exceptional level of accuracy, the final quality of the referencing operation, and thus of the resulting hybrid parts, is higher as well.

Multiple speakers at Molding 2023 will address the ways simulation can impact material substitution decisions, process profitability and simplification of mold design.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

While the adoption of AM is increasing, many manufacturers are still reluctant to take this step. One of the biggest challenges in using AM is the need to integrate the new process into manufacturing workflows built on well-established, mature manufacturing technologies. In particular, in the mould-making segment, additively manufactured components and inserts require – in nearly all cases – additional subtractive machining operations to achieve the very high surface quality required on the mould surface.

In this collection of articles, two of the industry’s foremost authorities on screw design — Jim Frankand and Mark Spalding — offer their sage advice on screw design...what works, what doesn’t, and what to look for when things start going wrong.

Additionally, some traditional design considerations for the mould-making sector are still valid in the case of additively manufactured moulds and dies. These mainly concern the minimum distance of channels from part walls for structural resistance, as well as the pressure drop throughout the whole channel path, and ease of cleaning (both mostly influenced by the channel section size, path and number of branches). Leakage is not an option. In these cases, the minimum distance should be large enough to safely process and post-process the mould. Thus, from the design phase, risks can be greatly reduced.

Thanks to their expertise in multiple fields and processes, GF Machining Solutions and 3D Systems are able to offer industrial solutions that make this possible. Their joint offering is further enhanced by the availability of dedicated products and tools, such as the Additive Molding module of 3D Systems’ 3DXpert software for the design and analysis of conformal cooling channels, and the DMP Calibration tool offered with the DMP machine series for the manufacturing of hybrid parts through the automated, user-error-free alignment of preforms and substrates to the highest accuracy inside the AM machine.

Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.

Although the benefits of AM for efficient cooling are well-documented and have often been presented, adoption has been slow due to initial concerns about material properties, costs, and a lack of knowledge on how to apply the technology in a market segment that is often regarded as quite traditional. In addition to the fact that mould makers are often risk-averse, they are generally under tremendous pressure to manufacture injection moulds at the lowest price possible. The use of additively manufactured inserts in moulds offers significant benefits, but also comes with additional costs. Mould manufacturers must, therefore, demonstrate the value of the additional investment to the final customer. This is clearly illustrated by the fact that adoption of conformal cooling has been higher in companies which manage both mould production and injection moulding. These companies fully understand the value, and actively incorporate AM into their manufacturing workflow, demonstrating return on investment (ROI) and increasing their use of the technology as they further master the process.

The generation of conformal cooling paths in adherence to the above design guidelines may quickly become very time-consuming with traditional computer-aided design (CAD) software tools. For this reason, a dedicated software solution such as 3DXpert®– and particularly its Additive Moulding Add-on – is very helpful for mould designers and tooling manufacturers in optimising part quality and reducing design and manufacturing costs.This add-on makes it possible to create conformal cooling inserts and to combine traditional and conformal cooling where appropriate (Fig. 4). This is made possible by a unique set of functionalities that save the user hours of design work before moving to the simulation-based verification and validation stages of the mould design:

Additive Manufacturing has proven to be a valuable solution for the optimisation of the cooling process, because it allows for the creation of cooling channels that closely follow the moulding surface – this is known as conformal cooling. These moulding surfaces can be highly complex and are therefore difficult to cool. AM enables the design and manufacture of parts that incorporate cooling channels that would be impossible to produce using conventional manufacturing technologies.

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.

Unlike many AM applications, here the manufacturing process begins with the machining of the preforms. In this case, the outer geometry of preform is typically produced by cutting a blank plate with wire electrical discharge machining (EDM). Ejection holes and cooling channels are, on the other hand, previously machined in the blank by deep-hole drilling. It is crucial that all preforms are identical in terms of height, since the Additive Manufacturing process must be conducted on a level plane.Beginning the process with subtractive machining, however, introduces new positioning and referencing challenges. This type of hybrid process must therefore start with the preform fixed on the build platform before the intended AM section is aligned by using a referencing system. The use of this type of referencing is especially challenging because, unlike in CNC machining, in an AM machine there is no physical link between the optics and the target substrate.

TK Mold uses the above-described process and equipment to produce high-quality hybrid parts, and manufactures around 90% of the moulds requiring AM-enabled conformal cooling by this method. As an example, the hybrid mould insert object of the smartwatch packaging support was achieved from a preform obtained by wire EDM in two different positioning steps. Each preform was then clamped onto the System 3R interface plate ‘AM Carrier’, mated with the DMP machine (Fig. 10). Here the DMP Calibration tool was exploited to correctly reference each preform independently through its set of two locating holes, automatically calculating and applying both translation and rotation corrections to the job file (Fig. 11).

Instead, manufacturers generally have to rely on visual alignment or external coordinate measuring machines (CMMs) to confirm positioning accuracy. Both techniques are time-consuming and, in the case of simple visual alignment, prone to operator error. With variances in excess of 100 µm, these techniques are also unable to provide the accuracy required for most final applications.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

By enabling the generation of conformal cooling paths within inserts, the adoption of AM in the mould and die sector has repeatedly been proven as an effective way to enhance the yield of moulding processes in terms of both productivity and part quality. This is confirmed by the application case study from TK Mold, and its now firmly established use of AM mould inserts in everyday production.

To improve the process, TK Mold’s engineers focused only on the improvement of the most critical mould inserts: those with the most influence in terms of cycle time or part quality. This is where the ROI in metal AM is the highest.

Injection moulding is, without a doubt, one of the most widely-used and successful manufacturing processes. It is most commonly applied to the production of thermoplastic and thermosetting polymer parts, using moulds manufactured from steel alloys, which allows for, in many cases, millions of injection cycles in serial production. The process entails injecting molten material into a cavity shaped like the final part, followed by rapid cooling to ensure hardening. The cooling time must, however, be sufficient for the part to properly solidify so it can be ejected with limited deformation. The cooling aspect of the injection cycle is, therefore, a key factor in achieving high-quality parts while keeping the cycle time efficient. Cooling of the mould insert is achieved by circulating a cold fluid (typically water or oil) through the mould to cool the mould surface.

This Knowledge Center provides an overview of the considerations needed to understand the purchase, operation, and maintenance of a process cooling system.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

Plastics Technology’s Tech Days is back! Every Tuesday in October, a series of five online presentations will be given by industry supplier around the following topics:  Injection Molding — New Technologies, Efficiencies Film Extrusion — New Technologies, Efficiencies Upstream/Downstream Operations Injection Molding — Sustainability Extrusion — Compounding Coming out of NPE2024, PT identified a variety of topics, technologies and trends that are driving and shaping the evolution of plastic products manufacturing — from recycling/recyclability and energy optimization to AI-based process control and automation implementation. PT Tech Days is designed to provide a robust, curated, accessible platform through which plastics professionals can explore these trends, have direct access to subject-matter experts and develop strategies for applying solutions in their operations.

In conclusion, for the mould and die as well as other sectors, a whole ecosystem has to be considered, encompassing software, AM and subtractive machines, materials, automation and tooling solutions. These must be efficiently combined and integrated to drive design and manufacturing costs down, thus allowing AM technology to express its full potential as an industrial process.

As the part is produced in large series, the packaging and the support must also be produced in large series. The challenges therefore relate to cost and productivity. As the final product is considered a high-value item, there are also requirements in terms of the support’s aesthetics.

In Fig. 7, we can observe the temperature inside the ‘outer channels’, which transport the coolant in the insert. In this image, the latter is located in the middle in a grey colour. We can already see a colder temperature inside the channels, but also more homogeneity between the conventional approach and the conformal approach.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

Once the part is built (Fig. 13), final machining operations are required to achieve the expected surface roughness on the final geometry. A first programming stage is performed to generate the tool path for the surface finishing of the required area. A real benefit here is 3D Systems’ Cimatron® software, which provides the technology user with a seamless transition between AM and post-machining.

In Fig. 8, we can analyse and compare the potential hot spots during injection with or without conformal channels. Here again, we observe a decrease in the temperature of the hot spots, going for example from 96°C to 86°C. Most important is the much more even temperature gradient, which is the critical factor influencing the quality of the part in terms of warpage and distortion. In this specific case, a productivity increase is the main goal, but customers are always looking for quality improvements.Today, these simulations are more reliable as rheology models have improved, taking cooling geometries into consideration; this type of data was previously not easy to simulate.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Before starting to build a mould insert in an AM machine, performing rheology thermal assessments is often done to detect where potential issues may arise. This makes it possible to interpret whether the optimised channels will be effective, particularly whether there is a need to improve the temperature homogeneity to reduce hot spots (Fig. 6).

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Through the adoption of AM, new design possibilities are available to mould manufacturers. Such design freedoms must be mastered, bearing in mind both the layer-by-layer manufacturing approach as well as the raw material involved in the process – the fine metal powder. These two elements result in a very limited set of constraints to the part design, mainly related to overhang regions, feature size and ease of powder removal. For additively manufactured parts with conformal cooling channels, such constraints may be easily overcome by adhering to a few design guidelines, which have become well-established over the years.

In addition, when using AM directly on a section of the final machined geometry, the costly cutting operation needed to remove the insert from the build platform is eliminated. This combination of subtractive and additive technologies – which is proving cost-effective – results in what is now commonly referred to as a hybrid part.

To overcome this issue, GF Machining Solutions and 3D Systems have developed a software solution that leverages the power of the meltpool monitoring hardware available on the partners’ DMP series of metal AM machines. In machines such as the DMP Flex 350, DMP Monitoring in-process monitoring software acquires meltpool data during the build process to detect potential defects such as lack-of-fusion pores.The DMP Calibration tool function exploits this light-sensing monitoring hardware for another purpose: scanning preforms to identify pre-machined locating holes in the part surface. The contrast in light reflection between the part surface and such holes allows for an extremely reliable method of establishing the precise location of the preform on the build platform (Fig. 9).

To explore the TP composite field, in 2016 CCP Gransden installed an Engel v-duo injection machine—one of the first of these units in the U.K. This is a servohydraulic machine with a vertical, two-platen clamp. It was developed specifically for composites applications. Its low operating height simplifies manual tasks and suits the machine well to R&D uses. The clamp can be equipped with a sliding table, facilitating a variety of automation concepts.

Productive Plastics has created an extensive collection of 3D printed manufacturing aids that sharply reduce lead times.

technotrans says climate protection, energy efficiency and customization will be key discussion topics at PTXPO as it displays its protemp flow 6 ultrasonic eco and the teco cs 90t 9.1 TCUs.

Such a solution can also help companies to meet demand without needing to invest in additional new moulds. According to TK Mold, the ROI on the production of this insert by AM is very attractive and, in this specific case, was achieved in fewer than twenty-six days of production.

First, the size and shape of the internal channels have design constraints. Large overhanging regions require support structures that are impossible to remove from the inside of the part after Additive Manufacturing. Channel diameters are thus constrained in size and self-supporting channel shapes (such as diamond, elliptical, or teardrop, among others) are preferable to the traditional round cross-sections typical when straight-drilled holes are used by traditional methods (Fig. 3).

Implementing a production monitoring system as the foundation of a ‘smart factory’ is about integrating people with new technology as much as it is about integrating machines and computers. Here are tips from a company that has gone through the process.

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

This machine has given CCP Gransden an entry into the promising technology of what the firm calls single-stage overmolding—which Engel calls the organomelt process. Long-fiber-reinforced blanks or organosheets—prepregs with a thermoplastic matrix--are heated in an infrared oven (incorporating special features of the molder’s own design) and then placed in the mold, where they are formed and directly overmolded with thermoplastic to create ribs, attachment points, and other functional elements. “Combining thermal forming and functionalization in the same mold and in a single stage make this process extremely efficient,” says Steve Taylor, sales engineer for Engel in the U.K. “Many competitors are still separating thermoforming of the organosheets and overmolding into two independent work stages, requiring two molds and often two machines. The integrated and fully automated process in a single machine is not only faster and more cost-effective, but also results in better part quality.”

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

Based in Ballygowan, Northern Ireland, CCP Gransden produces custom composite parts for aerospace, automotive, security and defense. Faster production, simplified processes, and recyclability are reasons why the firm is placing growing emphasis on TP composite technologies. The principal driver is the automotive industry, but aircraft manufacturers are also increasingly requesting thermoplastic solutions from CCP Gransden. Explains Peter Quigley, engineering manager, “We adapt processes developed for the automotive industry to aircraft manufacturing. The exciting thing is that we often bring back the optimized processes into the automotive industry, thus increasing efficiency and performance there.”

With AM, cooling channels can be set at a constant distance from the surface of the part to achieve uniform cooling, and deliver two main advantages:

While AM technology is helping many companies in the mould and die sector achieve new cost savings and efficiencies through conformal cooling, the economic viability of many applications requires other approaches. Indeed, for structural reasons, these applications typically include parts that require large amounts of mould material – in the case of AM, metal powder. This can make large parts costly to manufacture, as an AM insert’s price will be directly linked to the volume of material required for the AM process.

Once the program is ready, the insert is clamped inside a Mikron MILL S 400 U Milling machine from GF Machining Solutions. This product is well-established in the mould-making industry and enables a perfectly homogeneous surface finish. The excellent mould surface quality is particularly valuable for plastic parts with a final transparent finish, where flaws can be easily visible. Mirror surface finishing also reduces the need for hand polishing of mould components, reducing lead time. The square sections of the ejector pins required a milling operation (3+2 pre-machining) and a final grinding operation.

CCP Gransden started out using the machine for R&D sample parts with the new machine in both overmolding and HP-RTM, but customers pushed to use it for commercial overmolding production. “We are launching series production with the first customers,” states Jim Erskine, owner and managing director. “We can produce up to 100,000 composite parts per year from one tool.”

As a result, manufacturers expect metal AM providers’ solutions to cover the complete workflow, from design to final part, to deliver moulds that meet precise specifications. Software, AM machines, materials, subtractive technologies, automation and clamping solutions must be combined to provide an efficient ecosystem to drive down costs and complexity.

Injection molding was brand-new to CCP Gransden, so its team relied on Engel experts in the U.K. and its Center for Lightweight Composite Technologies in Austria. CCP Gransden learned the process on its new 1100-metric-ton v-duo press, equipped with a six-axis articulated robot from Stäubli. The entire process, including the IR oven, is centrally controlled by the v-duo’s C300 control panel. “This is a huge advantage for us,” says Quigley. “Integration of all control simplifies operation and provides a better overview, especially when the processes are complex.

Additional considerations are the cost savings that are available due to improved productivity by reducing the hourly cost of machine use and increased flexibility in terms of machine capacity. Due to the improvements in thermal homogeneity and the reduction or elimination of hot spots, TK Mold also improved repeatability and final part quality, thereby reducing these waste costs while better satisfying its end customer.

Metal AM magazine, published quarterly in digital and print formats, is read by a rapidly expanding international audience.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

Established in 1983, TK Mold is a subsidiary of TK Group (Holdings) Limited, a well-regarded manufacturer of plastic moulds and parts for a variety of industries including healthcare and consumer goods. TK Mold manufactures plastic moulds and parts for mobile phones, healthcare applications, smart homes, packaging and precision electronics. In addition to its Shenzhen base, TK Mold has three other factories in Suzhou and Huizhou, China, and Braunschweig, Germany.

With thirty-seven years of mould design and fabrication experience, the company is dedicated to providing the best performance injection mould solutions and final plastic parts. As both a mould maker and a parts producer, the company quickly grasped the advantages of metal AM and invested in it to develop mould inserts with conformal cooling channels. TK Mold’s mould-making and injection capabilities uniquely position the company to benefit from using these inserts to produce final parts – the benefits include productivity and quality gains, as well as the ability to deliver more efficient solutions to its customers.

Moreover, as this case study demonstrates, for companies to fully grasp the end-to-end value offered by this disruptive manufacturing technology, and thus quickly achieve ROI, AM should not be evaluated as a ‘stand-alone’ process. For the technology to shift to the full industrial scale, its integration with conventional, well-established manufacturing processes is crucial; a complete workflow approach, from design to final part, is required.

To demonstrate the benefits AM can bring to the injection moulding process, this article reports on how TK Mold, a customer of GF Machining Solutions’ subtractive and additive systems headquartered in Shenzhen, China (Fig. 1), is using Laser Beam Powder Bed Fusion (PBF-LB) technology and, specifically, how workflow optimisation was able to support the business case for AM mould inserts with conformal cooling.

The injection data collected in Fig. 14 show that the total injection cycle time varies between 21.70 and 21.79 seconds with a traditional insert. With the optimised insert, the cooling time of the plastic is reduced and cycle times stabilise between 16.98 and 17.01 seconds. This represents a significant cycle time reduction of 22%.

The simulation tools allow the designer to better predict the real-life efficiency, and thus more confidently design, the conformal channels placed inside the mould insert. It theoretically validates that the channels will have a positive impact on the injection process and, ultimately, on the plastic part. TK Mold uses these types of tools to demonstrate the added value of conformal cooling to its customers (internal or external) before the manufacturing of a mould.

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.
