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.

The EM5 was used to inject the red nylon 6/6 substrate while the black overmolded rubber was injected by the machine’s primary injection unit. In the design, the EM5 injected 864 g for the nylon 6/6 substrate, while the machine’s primary injection unit delivered the 800-g TPU overmold with a total cycle time of 70 seconds for the 2+2 mold. Normally, Frederick notes that the auxiliary unit would handle the rubber overmolding, but because the nylon 6/6 could degrade if the residence time was too long, Core utilized the EM5’s smaller barrel and shot size for the nylon. Shot sizes for the EM5 range from 550 to 1,200 g, says Dave Silva, Mold-Masters’ director of product development.

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

AE Plast opted for tiebarless multimaterial Engel victory machines as it took on complex parts for the appliance and power tool market, including a 3K housing for Dremel’s rotary tool.

Meanwhile, the machinery suppliers both have recently introduced new equipment to further progress in this nascent technology. Engel is recommending its new v-duo vertical large tonnage machines for Organomelt systems. Hydraulically powered with energy-saving servo-driven pumps, they are offered in five sizes from 400 to 2300 metric tons (see Sept. 2012 Close Up). The larger sizes are aimed at continuous-fiber composites, with their easy mold access to facilitate loading of reinforcing fabrics and organic sheets and tapes.

This is BASF’s first cooperative development in carbon-fiber composites. BASF is contributing its competence in polymer development as a leader in nylon and precursor caprolactam, while SGL brings its expertise in carbon fiber and high-temperature processes. In-situ polymerization technology is just now being developed in BASF laboratories under Martin Jung, head of structural materials research. According to Jung, starting with the low-viscosity, highly reactive caprolactam allows optimal wetting of the carbon fiber and short cycle times in T-RTM or reactive injection molding.

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

KraussMaffei has installations at university labs and tech centers worldwide and estimates that of the 50 FiberForm machines now in production, only a handful are currently overmolding glass mats; the majority are just molding long-glass compounds direct from rovings.

The biggest advantage for Core in shifting this production to two-shot versus insertion and overmolding was staffing. “The biggest piece is the labor aspect,” Frederick says. “You go from taking molded substrates and placing them in the tool, dedicating half an operator for just putting parts into boxes, to now where machines do all the work in one press with one mold.”

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.

Like Core, the customer is based in the Southeast — a region wanting when it comes to molders with 2-shot capabilities in the medium tonnage range (which is one reason Core got into multimaterial molding back in 2019). Core has a lot of exposure and expertise in automotive but serves a variety of markets beyond that, including medical, packaging and outdoor power equipment, among others.

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

Engel’s Kragl forsees further potential for both Organomelt technology and the in-situ polymerization approach. “In-situ will be a future technology for very efficient lightweight design. However, there are still many questions to be answered before it will be a stable, commercially available process. It also should be understood that in-situ will be very unlikely to achieve the same cycle times achieved by Organomelt.” He sees the in-situ technology being used primarily for nylon 6 and possibly nylon 12. Because of flammability issues, it may be more applicable to nonautomotive applications such as sports equipment and medical devices, at least initially.

Take a deep dive into all of the various aspects of part quoting to ensure you’ve got all the bases—as in costs—covered before preparing your customer’s quote for services.

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.

BASF’s Nichols expects an increase in shape complexity to facilitate market growth. This will require improvements in tooling that can preform composite sheet laminates and tapes with more 3D complexity and deep draws. KraussMaffei ventures that one way may be to use long-fiber compounds from an IMC machine in place of the organic sheet in some part areas that need more 3D form. According to a KM spokesman, “We will continue with our strong partnerships over the complete process chain to create knowhow for design and simulation of mechanical properties and the forming process. If all partners work together closely, there will be an economic solution.”

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

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

Machinery systems for in-situ polymerization of caprolactam into nylon 6 are under development at Engel. The company, which formed a Technology Centre for Lightweight Composites at its St. Valentin, Austria, plant last December, demonstrated a prototype in-situ composite molding system at an open house in June (see Sept. 2012 Close Up). It is based on an e-victory combi tiebarless press (120 m.t.) with two angled barrels and a high-pressure impingement mixing chamber adapted from PUR technology. It also features a new technology for feeding caprolactam flakes. One machine barrel feds caprolactam plus catalyst, and the other feeds caprolactam plus chemical activator.

“The logo aspect,” Frederick says, “that’s everything to the customer, and it’s really precision molding at that point. This is not a shoot-and-ship part, that’s an A surface, and we have to make sure our process is robust.”

•Hybrid technology was also used to make the first auto seat pan on a production vehicle, offering 45% weight reduction vs. standard seat pans (see cover photo). Featured in the new Opel Astra OPC sport coupe, it consists of a preform of continuous-glass fabric impregnated with nylon, which is placed in an injection mold and overmolded with impact-modified, short-glass reinforced nylon to form ribs and edges. BASF developed two specialty Ultramid nylon grades for this unit—one for impregnating the glass-fabric and one for injection overmolding.

•One of the most exciting parts was a passenger airbag module housing said to weigh at least 30% less than a current commercial version injection molded from glass-reinforced nylon 6. Now in advanced development in Germany, this project involves Lanxess, Bond-Laminates, KraussMaffei, Takata-Petri AG, and Christian Karl Siebenwurst GmbH. KM’s FiberForm process is used to make the airbag housing from Tepex dynalite 102 RG 600 sheet with 47% continuous glass, overmolded with Lanxess’ Durethan DP BKV 240 H2.0 with 40% short glass. In addition to weight savings, the high strength and stiffness of the sheet composite allowed thinning the sidewalls from 3-4 mm down to 0.5-1 mm.

The EM5 is attached to the molding machine in an L-shaped configuration on the non-operator side of the press with an injection point on the hot half, stationary half of the tool. E-Multi’s can be installed vertically, horizontally or at any custom angle to accommodate the cell. Freise says that due to the EM5’s size, Mold-Masters expect most of its installs will be horizontal.

This month’s resin pricing report includes PT’s quarterly check-in on select engineering resins, including nylon 6 and 66.

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

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

This all-plastic “organic hybrid” composite technology involves heating a continuous-fiber reinforced sheet blank impregnated with nylon 6, and then placing it in an injection mold, where it is formed into a 3D shape and overmolded with more nylon 6 (unfilled or glass reinforced). In some cases, the sheet blank is thermoformed separately before being placed in the injection mold. This metal-replacement technology is a successor to plastic-metal “hybrid” composites, which involved preforming sheet metal and overmolding it to add ribs, attachment points, and other features.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

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.

Whatever the label, this technology also has significant potential for use in other markets. There are variants of the technology in development that will further the use of thermoplastic composites in a range of industries that are seeking lightweight but high-strength material options, as well as the low cost, automation, and short cycle times possible with injection molding.

Engel’s Organomelt (above) and KraussMaffei’s FiberForm (left) processes are both used to produce all-plastic “organic hybrid” composite parts from continuous-fiber sheet blanks overmolded in an injection machine.

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.

Engel’s part, with its more complex geometry, was laser-trimmed outside the mold. In the case of KraussMaffei, which compounded the long-glass overmolding compound direct from roving on its IMC injection molding compounder, the robot transferred the net-shaped part to a quality-check station after molding.

This month’s resin pricing report includes PT’s quarterly check-in on select engineering resins, including nylon 6 and 66.

•Also considered a first for this technology is a brake pedal from Germany’s ZF Friedrichshafen AG, which weighs 355 g, half as much as a steel brake pedal. It is made of a Tepex dynalite composite sheet of nylon 6 with 47% by volume continuous glass fibers, which is heated, thermoformed, and cut to size before overmolding with Lanxess’ Durethan BKV 30 H2.0 nylon 6 with 30% short glass.

The initial development focus has been primarily on automotive interiors, including seating area components, door side-impact beams, cross-car beams, brake pedals, steering-column holders, airbag modules, and front ends. “At this time of increasing fuel requirements for automotive, OEMs are putting a lot of emphasis on lightweighting,” says Calvin Nichols, market development manager for automotive seating at BASF in Wyandotte, Mich. BASF refers to the technology as “continuous fiber-reinforced thermoplastic” or CFRT, while Pittsburgh-based Lanxess typically calls it “nylon composite sheet hybrid technology.” Similarly, Engel in York, Pa., refers to its process as Organomelt and KraussMaffei, Florence, Ky., calls its version FiberForm. The technology has also been described as “organic sheet overmolding.”

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

Last month, BASF and Germany’s SGL Group, a global leader in carbon-based products, announced they are jointly developing a composite material based on a reactive nylon system and carbon fibers that would allow cost-effective production of thermoplastic composites. The material system is intended for use in the T-RTM process (Thermoplastic Resin Transfer Molding) as well as reactive injection molding. It permits considerably shorter processing cycles than conventional thermoset RTM. Adjustment of the material system to these faster processing techniques is expected to play a key role in the entry of structural components made from carbon-fiber composites into automotive mass production.

A thermoplastic composite technology that emerged just a couple of years ago promises to make dramatic strides within the next two years in automotive mass production of structural components. At least two material suppliers—BASF and Lanxess—and two machine suppliers—Engel and KraussMaffei—are in the forefront of its development.

In addition to efficiency, Core said lead time and total cost helped make the case for the EM5. When quoting a dedicated 2K injection molding machine with a rotary table, Core was given lead times of 50 to 52 weeks, compared to 14-16 weeks for the EM5, which was slightly less than the quoted mold-build time for the job, creating a scenario where the EM5 could be installed and ready for the new tool to start production on day 1.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Both Engel and KraussMaffei first demonstrated the technology in two elaborate molding cells at the K2010 show in Dusseldorf, Germany (see our report in Jan. 2011). There, Engel molded a steering-column holder and KraussMaffei a door side-impact beam. Both used Tepex composite sheets from Germany’s Bond-Laminates GmbH and nylon overmolding compounds from Lanxess. (Lanxess recently acquired Bond-Laminates.) The two demonstrations used robots (linear or six-axis) to preheat the sheet in an oven at 300 C for 30-40 sec and then transfer the hot sheet to the injection mold. Closing the mold preformed the sheet, and then more nylon was injected over it in specific areas. Cycle times ranged from 33 to 55 sec. (the latter limited by oven-heating capacity).

One of the first to utilize Mold-Masters’ newest, largest auxiliary injection units —the E-Multi 5 (EM5) — Core Technology Molding Corp., Greensboro, North Carolina, was able to produce a 2-shot “bumper” component for a rolling toolbox cart four times faster and at half the cost compared to the prior production setup. “The previous process couldn’t make sellable parts in the same day,” explains Brandon Frederick, Core’s engineering manager. “Prior production had two different processes, two different tools and two operators. We’re half the cost — we didn’t need two machines.”

Joachim Kragl, director of advanced molding systems and processing at Engel, says there are today only a select number of Organomelt systems installed, most of them at university or independent laboratories, in addition to Engel’s own technology center.

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.

The two material suppliers displayed applications for the technology at K2010. Lanxess showed an Audi A8 front-end reinforcement molded by Germany’s Magna Decoma Exterior Systems, containing both aluminum and Tepex inserts overmolded with nylon 6. BASF displayed a seat back from Faurecia of France consisting of woven-glass/nylon sheet from California-based Performance Materials Corp., overmolded with a specially developed 35%-glass nylon 6 compound (BASF’s Ultramid CompoSIT XA3232) that combines stiffness, ductility, and Class-A-type finish. The part weighs about 20% less than standard seat backs and is expected to be commercial within the next two years.

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

To obtain an optimal bonding of the nylon to the fiber, the new matrix systems require a suitable carbon-fiber surface treatment. According to Dr. Hubert Jager, head of technology and innovation at SGL, “It is only with a custom-formulated finish that optimal bonding can form and the carbon fibers transmit their unique stiffness and strength properties fully to the part.”

BASF’s Nichols says, “Glass in a unidirectional form is much stronger than other forms of glass or ferrous and nonferrous metals. Such a sheet composite overmolded with nylon 6 has tensile strength as much as five times that of metals. Strength-to-weight ratio is dramatically improved over metals—twice that of steel and three-to-four times higher than a standard injection molded glass-filled thermoplastic. Stiffness-to-weight ratio with the continuous-glass composite laminate overmolded with nylon is eight times as much as steel.”
