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.

Nissei solved the problem of molding thin-wall, deep-draw parts like this two-piece champagne flute from PLA bioresin. Nissei injects supercritical CO2 into the melt to aid flow while maintaining microscopically small bubbles that don’t affect the crystal-clarity of the product. The flute was molded on Nissei’s new NEX280V-71E all-electric, Industry 4.0-ready press (below).

KraussMaffei showed the new Netstal Elios 4500 (450 m.t.) high-speed, hybrid toggle press. The series was launched at NPE2018 with a 750-tonner, which is now supplemented by models of 450, 550, and 650 m.t. Also new was a 21.5-in. multi-touch display on the KM CX 80 hydraulic machine with a PLC control based on the KM MC6.

And JSW has enhanced its Net 100 plantwide machine-monitoring system with newly upgraded J-Wise remote troubleshooting capability.

A key product of the alliance is the ADAMOS Hub, a software solution for manufacturer-independent access to applications of different providers. This one unique platform reportedly can interconnect all the machinery in a plant, eliminating “data silos” and permitting an integrated view of the operating status, settings, and performance parameters of all those machines. The Hub does not collect data from the machine, but shares access to the various controllers. The result, says Engel, can be one dashboard for a whole plant or department, rather than many dashboards for individual equipment. The result could be OEE (Overall Equipment Efficiency) calculation across all machinery, something that has not been possible before now. Another example could be monitoring energy consumption for a whole plant, with the ability to drill down to individual equipment. Another benefit would be the ability to purchase and manage apps from all providers centrally, as well as access to various providers’ customer portals. (See here for other K news from Engel.)

Another “green” thrust in molding exhibits involved processing of biobased materials. One impressive demonstration in this vein was Nissei’s production of champagne flutes from PLA bioresin. Nissei says PLA has poor flow characteristics, but was able to mold this deep-draw drinkware with what it claims is the thinnest wall ever molded in PLA—as thin as 0.65 mm over a flow length of 125 mm. To accomplish this, Nissei came up with a new way to inject supercritical CO2 into the melt to improve the fluidity of the material. Remarkably, the glassware is crystal clear, owing to the use of only 0.5% CO2 and the microscopic size of the gas bubbles.

Arburg also initiated the spread of features launched with the new hybrid Allrounder “H” series at K 2016 to other Allrounder lines. At this show, the all-electric 570 A (200 m.t.) and 630 A (250 m.t.) appeared for the first time with the new “H” series clamp design, exterior styling, and Gestica controller with gesture-based commands.

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

In addition, several new features have been introduced to Milacron’s LPIM line, including the Mosaic+ control, which has VNC capability to mirror control screens from third-party auxiliaries like robots and hot-runner controls (for the latter, Milacron has standardized on Mold-Masters’ TempMaster system). This allows both monitoring and setup of the auxiliaries from the injection controller. Also new for LPIM machines is a hybrid option with a Fanuc servomotor and drive package for the screw, cutting energy consumption by 20-25%. Other new features available for LPIM machines in the last year are a 7-in.-diam. extruder capable of plasticating 3200 lb/hr, 4500-in.3 accumulator, and 10,000-psi injection-pressure capability, vs. the standard 6000 psi.

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.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

Also unique to this system, the entire screw/plunger barrel assembly moves forward to inject, emptying the melt chamber in front of the plunger through a Mini-Shut shutoff nozzle on the end of the barrel. This design is said to be simpler, more compact, and less costly than other two-stage designs.

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 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.

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.

New “digital assistants” include the “filling assistant” for the Gestica controller, which provides a 3D graphic animation of the fill level of the part in relation to the screw position; and the “plasticizing assistant,” which utilizes a memory chip integrated into the barrel to record data on the working history of the screw and barrel to facilitate predictive maintenance.

Wittmann Battenfeld introduced a high-performance plasticating unit with modified barrier screw and improved throughput rate for molding PET blood tubes in 48 cavities on an all-electric EcoPower Xpress 160-m.t. medical machine.

Victor Taichung of Taiwan (represented by Fortune International) brought out its third-generation all-electric series, the Va III. The first machine in the line is the biggest model, 230 tons, which was displayed at K. The line will start at 50 tons. Features include an upgraded controller and linear bearings on the injection carriage. The 230-tonner has tiebar spacing of 610 × 560 mm, shot capacity of 536 g (PS), clamp stroke of 520 mm, and injection speed to 160 mm/sec.

Also new is easyTrace, a central data hub for collecting all relevant production data for any age, type, and brand of machine, including extruders, injection presses, and auxiliaries (dryers, cameras, scanners, automation systems, quality test instruments, etc.). It’s described as a “lean” solution tailor made for plastics, which translates different signal-transmission protocols for communication with MES and other central plant IT systems. EasyTrace reportedly supports nearly all interfaces that exist in the market, including Euromap 63 and 77, Profinet, etc.

All these problems can be reduced or eliminated with two-stage screw/plunger systems, of which Inject-EX is a new variant. Like other two-stage systems, this one has a plasticating screw (Md Plastics’ Posi-Melt design) that is stationary with respect to the feed hopper and that feeds an injection plunger via a shutoff valve. What’s different about Inject-EX is that the screw and plunger are not housed within separate cylinders, but are directly coupled inline. The screw feeds melt through a channel or “inner barrel” in the center of the injection plunger, and the melt exits that channel at the front of the plunger. The valve between the screw and plunger sections is the same one used in Md Plastics’ Mini-Shut shutoff nozzle. This is a poppet valve that is spring loaded with Belleville washers. It therefore shuts immediately when the screw stops turning. This design provides true “first-in/first-out” melt inventory, unlike most other two-stage designs.

Smart machines, smart production, and smart services—the three-part mantra of Industry 4.0 drove a lot of the news at K 2019. Arburg, for example, promoted all three as part of its “arburgXworld” (pronounced “Arburg’s world”) concept. Available in Germany since last March, it is now active globally in 18 languages. In future, all Allrounder macines will be equipped with Basis Connectivity, an IIOT (industrial internet of things) gateway to networking with higher-level software tools and the web portal.

As noted above, Nissei previewed its NEX-V Series of all-electric injection machines for the global market. The model at the show was a 280-m.t. unit, but it will be available—starting this spring—in 30 to 360 m.t. It’s said to have one of the widest platens and longest daylights in the industry while maintaining the industry’s smallest footprint. The main new feature is the TACT5 controller, designed to be Industry 4.0-ready with OPC-UA communication protocol standard and Euromap 77 and 82 capabilities available, respectively, for integration with MES systems and with mold-temperature-control systems and hot runners. The controller has a 15-in. screen with top and bottom dual windows. Nissei says this is also is one of the first machines to conform to the upcoming ISO20430 Universal Injection Molding Machine Safety Standard.

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

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.

Driven by brand owner demands and new worldwide legislation, the entire supply chain is working toward the shift to circularity, with some evidence the circular economy has already begun.

As stated by Michael Durina, president of Md Plastics, the Inject-EX plasticating system was developed “to ensure that each pellet is exposed to the exact same amount of energy during its journey from the hopper to the mold. The result is a melt that is more uniform and homogeneous than is produced by today’s reciprocating-screw systems.” He explains that as the conventional reciprocating screw retracts during recovery, the pellets entering the feed throat are exposed to a continuously changing L/D, so their shear exposure is inconsistent, which leads to viscosity variation. That effect is exacerbated by the fact that when the screw moves forward during injection, pellets fall from the hopper into the empty screw flights. Those pellets are not compacted efficiently during the next recovery cycle, creating further melt variability. Add to these problems the well-known issue in conventional machines of inconsistent shot volume due to inconsistent closing of the check valve at the end of the screw at the start of injection.

Incidentally, Elmet noted that the emergence of LSR 3D printing has opened up a new market. A single TOP 5000 system could feed 10 to 20 3D printers.

At NPE2018, Md Plastics showed off the prototype of a novel inline screw/plunger system called Inject-EX, designed to overcome the limitations of standard reciprocating-screw injection molding machines. Since then, the design has evolved, with an improved heating system and, most importantly, a Taiwanese machine builder has adopted the Inject-EX system for a series of presses to be marketed here by Md Plastics.

Zeiger Industries has enhanced its LSR conversion kits with new quick-disconnect water-cooling jackets for the barrel to facilitate maintenance. These also come in a toolless version. Also new is a connection to allow easier uncoupling of the pump assembly from the barrel. This version eliminates threads, reducing the risk of damage to the barrel in case of LSR leakage into the coupling, which can lock the threads.

For PET preforms, SIPA of Italy introduced an enhanced version of its hybrid XForm system, dubbed Gen4 XP. It reportedly provides a new operator experience with a 21.5-in. touchscreen with high-definition graphics, swipe functions like a smartphone, and a multifunction control knob for one-handed operation. The control features automated setup routines and an in-depth part-quality troubleshooting tutorial. The servohydraulic toggle boasts a record fast dry cycle and braking kinetic-energy recovery system. Other upgrades are increased injection rate and energy efficiency—the latter is said to be typically 0.195 kWh/kg (0.886 kWh/lb). Cycle time for a 7.5 g preform is said to be 7.5 sec. Maintenance is reportedly made easier by mounting the accumulators on a pull-out rack inside the machine frame and redesigning the oil tank so that it doesn’t have to be emptied for maintenance. What’s more, SIPA introduced a smaller size in the XForm range—250 m.t., suited to 96 cavities; existing models are 350 m.t. for 128 cavities and 500 m.t. for up to 180 cavities.

Sumitomo (SHI) Demag added models and sizes to several lines of machines. Its IntElect S high-speed, all-electric series for thin-wall and precision parts in cycles of 3 to 6 sec will gain a new larger size—500 m.t.—this year (complementing the new 500-m.t. IntElect model for general-purpose technical molding in cycles under 10 sec). Also, the IntElect Multi line of two-component machines for automotive and consumer parts will extend its size range from 100 to 180 m.t. upward to 500 m.t. this year.

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.

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

New from Nissei is the N-Constellation system for networking all cell components—robots, dryers, feeders, TCUs, etc.—using Euromap communication protocols and EtherCAT, with the new TACT5 injection-machine controller as a hub.

In the meantime, Sumitomo Demag is exploring use of AI to predict part quality based on process data. For these trials, Sumitomo Demag has interfaced STASA QC software with its NC5 machine controls. STASA QC, developed by Steinbeis Angewandte Systemanalyse GmbH (Steinbeis Applied System Analysis) in Germany, is supplied by Kistler Group in its newly commercial ComoNeo Predict software. STASA QC uses machine learning to predict quality data such as part dimensions based on the cavity-pressure curve derived from in-mold sensors. The result is automated QC without time-consuming metrology tests. STASA QC software is “trained” by means of DOE configured by the software and executed automatically on an injection machine. (More details in Keeping Up section.)

Meanwhile, Sumitomo Demag’s El-Exis SP high-speed packaging hybrid series gained a new 1000-m.t. model at the upper end of its size range, aimed particularly at pail production. Accumulators provide 1000 mm/sec injection speed. At the show, it molded two 17 L PP pails (675 g each) from 50% PCR, with IML, in 12.9 sec.

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

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

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

Negri Bossi also displayed a Cambio St servohydraulic toggle press outfitted with the new Motus control system (from B&R in Austria) with 21.5-in. multitouch display. It has a finger-operated mini-joystick that can be used in setup mode to move the screw, clamp and ejector. This is the same controller used on the new Nova s servohydraulic toggle and Nova i series. Coming soon is a new injection unit for Cambio presses.

Another unusual demonstration at K was the debut of a machine and material for molding a new kind of eco-friendly products. Zeroplast is a patented material from a Polish company of the same name (zeroplast.com) that is composed entirely of mineral and nonfood plant-derived waxes, fibers and fillers (including rice hulls and calcium carbonate). This “plastic-free” material is compostable and biodegradable in natural environments. It is also recyclable without any loss of properties, the company says. The material is said to be heat stable to greater than 200 C (392 F) in processing and to 70-75 C (158-167 F).

Also on display was one of the new Nova e 130T all-electric presses converted to an injection-blow molding system by means of a mold from Molmasa of Spain. The tool has eight preform injection and eight blowing cavities in alternating positions. A mold plate shuttles up and down to move preforms to blowing cavities. It’s suited for small to medium production. (Other tooling-related conversions of injection presses to injection-blow were shown at K 2016 by Boy, Engel and Wittmann Battenfeld.)

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.

Chen Hsong is offering several new lines of machines, not all of which were at the show. The Jetmaster MK6 line of servohydraulic toggle presses comes in 88 to 668 m.t. The clamp, base, and injection unit have all been redesigned and beefed up. Also redesigned is the Jetmaster Large SVP/2 series from 650 to 3000 m.t. New Evolution MK6e servohydraulic toggles (90 to 650 m.t.) are a lower-cost version said to be suitable for 80% of the market. The powerpack has been downsized somewhat, so these machines are not optimal for high-volume or high-torque production. There’s also a smaller new low-cost line, Focus SVP/2 from 20 to 60 m.t. At the higher-performance end is the new Speed series of servohydraulic toggles (128 to 468 m.t.) with a “top-of-the-line,” high-response servomotor for ultra-high-speed injection. The related new Speed-Pack series (260 to 470 m.t.) has longer screws, up to 26:1 L/D. Finally, a new all-electric series is the Spark line from 100 to 230 m.t., boasting a more compact and more open design.

Other examples at the show included Boy Machines processing wood-plastic compound (Fibrolon from FKuR) on a Boy 125 E. Husky highlighted the ability of its newest HyPET HPP5e system to mold PET bottle preforms from 100% PCR with no sacrifice of cycle time or product quality (e.g., color). What’s more, the Husky machine can take molten PET reclaim directly via melt pipe from Erema, NGR, or other recycling systems, thereby eliminating pelletizing, crystallizing and drying steps and saving large amounts of energy. Husky says customers prefer this approach to feeding reground flake. This “RMTP” capability is expected to be commercial mid-to-late this year.Machine capabilities to process large amounts of recycle or bioplastics supported the “green” theme of K 2019.

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.

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.

Meanwhile, Wittmann Battenfeld introduced a data reporting and analysis concept that does not require access to company IT systems or external (cloud) data storage. The new TEMIone “one-machine MES” package comes from Italian software firm ICE-flex (partly owned by Wittmann). This involves installing a server inside the machine control cabinet that is integrated with Wittmann Battenfeld’s B8 machine controller and Wittmann 4.0 Com-X router. This allows TEMIone to access and store production data from the press and cell peripherals to provide completed data traceability for up to five years of production. It can display customized KPIs (key process indicators) in a dashboard and an hourly OEE trend for the machine and workcell. It also merges error messages from individual devices into one clear error list. Data can be stored externally via USB or network connection.

Our September show preview highlighted several exhibits of machines from Arburg, Engel, KraussMaffei and Wilmington Machinery tailored to handle large amounts of regrind or PCR, in some cases through foaming and/or sandwich molding.

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.

JSW introduced its patented SOFIT foam injection technology. It involves injecting nitrogen gas into the barrel in a decompression zone after the melting zone and before the metering/compression zone. A special screw and barrel are required, but a cost-saving feature is the ability to feed nitrogen directly from a storage tank via a pressure-reducing valve, with no need for a high-pressure metering pump.

The ‘DryerGenie’ marries drying technology and input moisture measurement with a goal to putting an end to drying based on time.

A profusion of new and upgraded injection machinery at K highlighted twin themes of Circular Economy and Smart Manufacturing. While presses keep getting faster, they also grow ever more energy efficient in kWh/lb of plastic processed. The vast majority of injection machines at the show were all-electric, hybrid, and/or servohydraulic. This year’s exhibits featured machines equipped to process large amounts of post-consumer recycle (PCR) or biobased materials.

While the EdeX models initially offered by Md Plastics are designed for thermoplastics, Durina hopes to offer LSR versions in the future. (An Inject-EX system for LSR was shown at NPE2018). “They won’t need a screw at all,” Durina says. “The silicone material can feed directly into the inner barrel of the injection plunger where the end of the screw would normally be. And we can put a static mixer at that entry point, so there would be no need to premix the two LSR components in the feed system.”

Blazing speed plus shrinking energy consumption supported the “green” theme at the big show. Smarter controls and growing connectivity were another key focus.

NPE2024: Sumitomo SHI Demag’s show focus is on the application of all-electric injection molding machine technology for a variety of markets and components.

At the show, Wittmann molded a thick-walled cosmetic jar and cap with the heavy feel of glass, molded in two colors in 4 + 4 cavities, with a paper in-mold label (uncoated for biodegradability) and automatic assembly of jar and lid in a screwing station outside the press. (Wittmann Battenfeld will present this innovation in the Green Molding session at the Molding 2020 Conference.)

Zeroplast worked with Wittmann Battenfeld on an exclusive basis to develop a molding process for this material. The result is a specially modified, all-electric EcoPower 240 press (240 metric tons) with a special injection unit, heating system, and processing software. According to Wittmann sources, this system was adapted to the Zeroplast material’s sharp transition from solid to liquid and the resulting narrow process window.

The glasses were molded in two parts, a base and cup in a cell utilizing two presses with Cartesian robots that deliver parts to an assembly station with a Kawasaki DuAro two-armed collaborative SCARA robot. The machine were Nissei’s brand-new, all-electric NEX 280V-71E (details below). One press molded the 185 g cups in eight cavities in 37 sec, and the other molded 108 g bases (o.74 mm thick) in four cavities in 72 sec. (Nissei will be speaking about this application in the Green Molding session at the Molding 2020 Conference, March 17-19 in Lombard, Ill.)

Milacron is tripling its workforce for digital solutions and is enhancing its M-Powered suite of Industry 4.0 services and predictive functions through partnership with ei3, a 10-year-old firm based in New York with offices in Montreal, Copenhagen and Zurich), which specializes in remote collection and analysis of industrial machine data. Ei3 believes such data “becomes more valuable when securely liberated from the plant floor.” Its latest innovation is AI developed through ei3’s Data Science center in Zurich. Milacron says this AI paves the way for new applications to support preemptive spare-parts stocking and expanded lifetime tracking for tooling and auxiliary components. Building on these capabilities, Milacron’s M-Powered is now able to interpret the data to determine impending failures, maintenance needs, or incorrect machine settings. Any Milacron machine can be enhanced with ei3 AI capabilities in less than two weeks, the company says.
