A new 50-ton vertical-clamp/vertical-injection machine will debut at NPE from Wabash MPI, Wabash, Ind. The WPR 50/150 has a four-station rotary table and 5.5-oz injection unit. It is controlled by a DataTrend III system and Allen-Bradley Panel View-600 touchscreen.

MGS Enterprises, Inc., Germantown, Wis., will show how to convert a standard injection press to multi-material capability. MGS’s Universal Multi-Shot (UMS) machine is a small injection unit that mounts vertically atop an existing press. It comes with its own hydraulic power pack and Allen-Bradley controls. MGS will introduce a twin-barrel version of the UMS to permit three-shot molding.

Another two-platen series with retractable tiebars is available from Po Yuen (To’s) Machine Fty. Ltd. in Hong Kong. Size range is 600 to 3000 tons.

Netstal Machinery Inc., Devens, Mass., will show the new top end of its SynErgy line, the model 6000 (660 tons). It is accompanied by new models 4000 and 5000 (440 and 550 tons).

Updated versions of the Butler benchtop 9-ton mini-press will be shown by MCP Equipment of the U.K. (represented by Tomken Tool & Engineering, Inc., Muncie, Ind.). The MCP Butler 12/90 H.S. unit has a 9-ton, air-operated clamp and 0.4-oz shot capacity. It has two-stage, screw/plunger injection and Omron controls. MCP also has a new hydraulic version of this machine and a vertical-clamp pneumatic model.

In-mold laminating: Krauss-Maffei is introducing to North America the Decoform process for low-pressure back-molding of decorative coverings via injection-compression on a horizontal press. A door panel will be molded on a 1300-ton machine. K-M will also highlight the Decopress technique for accomplishing the same goal via open-mold injection into a vertical press.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

Two brand-new series of medium-sized machines are being launched at NPE by Van Dorn Demag. Its new Pinnacle Series has a more robust five-point toggle that is designed to reduce platen deflection and overall machine length. For quick barrel changes, it has quick disconnects and an Automatic Barrel Identification System in the controls that adjusts the machine settings to the new barrel. Whereas Van Dorn’s previous toggle machines had two barrel choices, the Pinnacle Series offers three: standard, high-pressure, and extra-high pressure. Two variable-volume “smart” pumps have the electronics on the pump rather than on the hydraulic valves, which is said to provide faster response. Two Pinnacle presses of 140 and 280 tons will be shown. When the full line comes out by the end of 2001, it will reach 625 tons.

Brazil: Reed-Prentice Ltd., West Springfield, Mass., is getting back into horizontal toggle machines with a line from 75 to 2000 tons built by former Reed licensee Industrias Romi, S.A. Another Brazilian visitor, Himaco Hidraulicos e Maquinas Ltda. of Novo Hamburgo will demonstrate a 165-ton machine at the show. It makes toggle presses from 66 to 550 tons, including horizontal, vertical, two-color, and rotary models.

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.

Meanwhile, Nissei America Inc., Anaheim, Calif., will get the prize for the smallest all-electric machine at the show. Its HM-7 Denkey (7.6 tons), mounted on a wheeled cart, has the industry’s first electromechanical “direct-pressure” clamping mechanism. All other electric clamps use toggles. Nissei officials say ball-screw-driven direct clamping (also to be shown on the new ED3000 machine of 167 tons) is better than a toggle for ultra-precise molding.

Two Japanese machine builders are showing a new style of hybrid clamp. The new Nadem line of Meiki America Corp., Elk Grove Village, Ill., and the Tuparl EH series from Sodick Inc., Torrance, Calif., both have hydromechanical clamps in which servo-driven ball screws open and close the clamp quickly. After the mold closes, a hydraulic locking mechanism engages the ball screw, and small hydraulic cylinders apply clamping force (see PT, April, ’00, p. 50). This arrangement reportedly combines finer and more uniform pressure control with the greater speed and position accuracy of electric motors. Both machine lines also have electric screw drives.

For molding really small parts, you’ll have to see the 5.5-ton MicroSystem from Battenfeld of America, West Warwick, R.I. In its first U.S. appearance (it debuted at K ’98), this all-electric machine has shot capacities from 0.45 to 1.45 g. Its unusual three-stage injection system (plasticating, dosing, and injecting) can fill at pressures up to 61,500 psi. A rotary table allows molding to overlap cooling and ejection so that cycle times can be as short as 5 sec.

Three other firms will make their all-electric debuts in North America. Kawaguchi Inc., Buffalo Grove, Ill., will show its first horizontal all-electric model. (It makes vertical electric presses in Japan but does not offer them here.) The KXE 55-tonner has two-stage injection.

August 29-30 in Minneapolis all things injection molding and moldmaking will be happening at the Hyatt Regency — check out who’s speaking on what topics today.

Van Dorn Demag also sees a need for larger insert-molding capability. It has introduced a larger Newbury Vertical machine of 140 tons to replace the former 125-tonner. A new 80-ton Newbury Vertical model will also be shown.

Van Dorn Demag Corp., Strongsville, Ohio, will show two different types of hybrids at NPE. One is a new high-speed version of the 500 HT toggle press (500 tons) with an electric screw drive, “super clamp,” and injection accumulators.

Nissei’s HM7 Denkey is not only the smallest all-electric machine at the show (7.6 tons), but also the first electric machine that uses direct-pressure clamping instead of a toggle.

Coverage of single-use plastics can be both misleading and demoralizing. Here are 10 tips for changing the perception of the plastics industry at your company and in your community.

Those features (except for an upgraded MAC VII control) are also found on the brand-new MMJ series of 610 to 1200 tons. These “21/2-platen” hydromechanical machines have almost as small a footprint as a two-platen design (22% shorter than a fully hydraulic machine), plus reduced platen deflection for very precise molding, Mitsubishi says. Instead of clamping on the tiebars at the four corners of the mold, the MMJ has a large central clamp cylinder that travels along with the moving platen (see schematic). Like a two-platen machine, it uses a diagonal pair of small rapid-traverse cylinders to open and close the mold, plus locking nuts to grip the tiebars before clamping. Dry cycle is said to be 18% shorter than a fully hydraulic press. Both the MMJ and MM III series offer a new low-pressure molding option in which the injection speed is controlled by the cavity pressure. It is said to permit fast injection of large automotive parts without flashing or short shots.

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.

Electric drive on the screw, rotary table, and ejectors are modifications to a basic Gluco 100-ton vertical press that will be shown by PlastiMatix LLC, Farmington Hills, Mich. Whereas Gluco specializes in thermosets, this press is designed for thermoplastics. It has horizontal injection and a four-post cantilevered clamp in place of Gluco’s standard C-frame. Less deflection is said to result.

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

The new standard line of hydraulic-clamp machines from Mitsubishi is the MSJ series, ranging from 90 to 500 tons. Among the many improvements over the earlier MJ series are larger platens and tiebar spacing, greaseless tiebars, dual injection cylinders, simplified hydraulic piping for “zero leaks,” 20% more rigid platens, jet-purge circuit, and new MAC-VII controls. Models up to 320 tons also have three-way take-out and variable-volume pumps.

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.

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.

"Alltrista is the first in the world to produce with 128 cavities and a cycle time of 1.9 seconds,” said Horst Kogler, head of Netstsal’s caps and closures business unit. “They produce more than 3.1 billion closures with two lines [annually]. More output per square meter of production area is currently not possible."

Hong Kong: A new generation of five-point toggle machines with 35-40% greater injection-pressure and plasticating capacity comes from Chen Hsong Machinery Co., Ltd. Jetmaster MKIV models of 80, 130, and 170 tons will be shown, as well as a 550-ton hydraulic-clamp press.

New MMJ Series of large presses from Mitsubishi almost matches the footprint of two-platen machines but avoids platen deflection with a central clamp cylinder.

Arburg is breaking out of the small-machine category with its largest model ever, a brand-new 300-ton, 29-oz hydraulic-clamp press, the Allrounder 630 S.

Gas venting: Kawaguchi will also introduce its SGV (Simple Gas Vent) technology. By venting gas through the nozzle end cap during injection, drying time can be reduced by half, company spokesmen say. SGV is reportedly adequate for removing surface moisture and for avoiding splay in ABS. It is not recommended for PET or PBT.

A Multi Mat two-color machine with a rotary mold will be shown by Y.K. Seiki Ltd., which builds toggles from 22 to 495 tons.

Mitsubishi/MHI has two large-machine entries in store for NPE. One is the third generation of MM III two-platen presses (1450-4400 tons), whose new features include the MAC-VI color CRT control, UB screw for improved productivity, “jet-purge” circuit for quicker color changes, clamp-braking circuit for increased position accuracy, and a built-in oil cleaner.

Overall, Netstal’s CAP-Line also fits in a smaller overall space — 538 square feet — and uses about 12% less electricity than competing machines running 96-cavity molds, Kogler said.

To replace its long-selling PS-type machine, Nissei will introduce the PN60E compact, precision-molding machine with 70-ton hydraulic clamp. It has a new injection mechanism and is optimized for extremely uniform plastication.

The first all-electric machines from Italy, made by Bodini Presse s.r.l., will be shown here by PlastiMatix LLC of Farmington Hills, Mich. They come in 28 to 330 tons, soon to be followed by a 550-tonner.

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

NPE will be a prime opportunity to get acquainted with numerous overseas machinery vendors from countries other than Europe or Japan:

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

HPM Corp., Mt. Gilead, Ohio, is showing off its recently updated and “Americanized” NextWave two-platen machines with retractable tiebars (PT, March ’00, p. 48). Two models of 880 and 1375 tons will be shown.

Also extending the range of its electric machines—at both ends of the scale—is Toshiba Machine Co. America, Elk Grove Village, Ill. It will bring new models of 22, 186, 242, and 386 tons. (Earlier sizes are 44, 66, and 110 tons.)

Another micro-molding entry will be introduced by Arburg. The new 17-ton Allrounder 220 S 150-35 will demonstrate metal- or ceramic-powder molding at the show. Arburg is also adding a 77-ton toggle machine (Allrounder 320 K) to its current 28- and 40-ton offerings.

Netstal’s CAP-Line 4500 is identical to two production systems being used by Alltrista, a contract manufacturer based in Greer, SC. The line features an all-electric clamping unit with 4,500 kN of force and a dry cycle time of 1.4 seconds. An optimized barrier screw allows for a smaller injection unit with higher plasticizing performance and better homogenization, Netstal expained.

New from Presma Corp., East Brunswick, N.J., is the Roto HSP/2/BIC, a 10-station, 55-ton rotary coinjection and structural-foam machine that has four barrels.

Wittmann Battenfeld says its upgraded Airmould 4.0 technology, which features a more compact footprint, saves material and cycle time — thereby also cutting energy use.

The abundance of injection molding news at this year’s show is staggering. There are more and bigger all-electric machines than ever, including first-time introductions by several suppliers. Electric technology is also taking new forms, such as beltless drives and “direct-pressure” clamping without a toggle. Energy-saving electro-hydraulic hybrids are also evolving.

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

Two other firms showing electric-screw hybrids will be Arburg Inc., Newington, Conn., and Sandretto USA, Inc., Freedom, Pa.

India: Closed-loop injection-pressure control is a new feature on the Indigo series of horizontal presses, built in India by Cincinnati Milacron Ltd. and marketed here by Autojectors. They include toggles of 33 to 440 tons and hydraulic models of 500-1000 tons.

Mike Sepe has authored more than 25 ANTEC papers and more than 250 articles illustrating the importance of this interdisciplanary approach. In this collection, we present some of his best work during the years he has been contributing for Plastics Technology Magazine.

Toyo of Japan (represented by Maruka U.S.A. Inc., Rockaway, N.J.) will bring a new 300-ton electric machine that extends its Plastar Si Series beyond the previous top end of 200 tons.

Van Dorn will also show two versions of the Demag Ergotech El-Exis machine, one of which has not been seen before. Demag displayed a prototype high-speed version of the El-Exis at K’98 in Dusseldorf and will have a 265-ton El-Exis S model in Chicago. It has electric screw drive and an electric motor with a “hydrostatic gear” transmission to power two hydraulic cylinders on the five-point toggle clamp. (The hydrostatic gear system utilizes a small amount of oil in a localized closed loop with no return to tank.) Injection is accomplished with a gas accumulator and variable-volume hydraulic pump. The latter also powers the nozzle motion, core pulls, and ejectors. This concept reportedly achieves power savings of 40%.

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

Electric servo-driven presses will be more numerous at this show and physically larger than ever before. At least 11 companies will display all-electric machines this year, compared with two at NPE ’97. Hulking on the show floor will be the largest all-electric model ever yet built: a 1550-ton Ultima UN machine from Ube Machinery Inc., Ann Arbor, Mich. It will be accompanied by last year’s largest electric press, now the second largest at 1100 tons. Ube and partner Niigata in Japan are jointly developing even bigger electric models than these.

New ways to power injection machines are exemplified by this novel hybrid from Van Dorn Demag. A servo motor rotates one way to turn the screw and reverses direction to power the hydraulic injection cylinders.

As at the last NPE, vertical presses for insert molding will make a strong showing:To satisfy growing interest in insert molding of larger parts for cars and appliances, Autojectors Inc., Avilla, Ind., is bringing out its largest model yet. The HCR-280 is a 280-ton press with four-station rotary table.

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.

Added Christopher Navratil, CTO of Alltrista's parent company: "We were determined to be the first manufacturer to run a system with 128 cavities in under two seconds. In Netstal, z-moulds, and Intravis, we have found the best system partners for this project. Each company is a leader in its field, and the combination is unbeatable. With our 128-cavity systems, we produce more efficiently than ever before, can deliver at any time, and inspire our customers. This has given us an enormous competitive advantage."

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.

"With the new CAP-Line concept, we are aligning our portfolio even more closely with our customers' applications,” he noted. “Closure manufacturers benefit from a customized system, while pre-configuration can speed up the consultation and quotation process so that delivery times for the machine are as short as possible."

It used to be the largest all-electric machine ever built, but this Ube 1100-tonner will be accompanied in Chicago by an even bigger brother of 1550 tons.

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

Shown for the very first time at NPE will be the “standard” El-Exis E version in a 165-ton model. It differs from the S version in replacing the injection accumulator with an unusual servo-motor system. The AC motor on the injection end turns in one direction to drive the screw directly. When the servo motor runs in the reverse direction, it disengages the screw drive but instead powers a hydrostatic gear that drives two hydraulic injection cylinders (see schematic). Power consumption is said to be similar to an all-electric machine.

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.

A collaboration between show organizer PLASTICS, recycler CPR and size reduction experts WEIMA and Conair recovered and recycled all production scrap at NPE2024.

China: Haitian Machinery Co., Ningbo, will introduce its faster HTW Series of toggle presses (99 to 1188 tons), which have enlarged tiebar spacing. It will show 97- and 308-tonners.

The Japanese-built Milacron Fanuc series of all-electrics has grown larger, too, with the new Roboshot “i” series that extends from 17 to 385 tons. (see PT, April ’00, p. 38).

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

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.

Formnext Chicago is an industrial additive manufacturing expo taking place April 8-10, 2025 at McCormick Place in Chicago, Illinois. Formnext Chicago is the second in a series of Formnext events in the U.S. being produced by Mesago Messe Frankfurt, AMT – The Association For Manufacturing Technology, and Gardner Business Media (our publisher).

The mold, produced by Austria’s z-moulds, is as small and light as a 96-cavity mold and fits into the injection molding machine with a smaller column distance. Cycle time is reduced by the smaller design, which also requires moving less mass. Alltrista has cut the weight of its enclosures by 25%; with 3.1 billion closures produced annually, that means more than 2 million pounds less resin used – about the weight of 160 African Bush elephants, the company said.

Two firms will introduce high-speed injection systems. Sumitomo will show its HP-Plus Option, in which a small gas accumulator is mounted directly on the injection unit. And Meiki is showing one of its new MC-AS high-speed, high-pressure machines for thin-wall, tight-tolerance parts like connectors. It uses an accumulator, servo valve, new high-response injection control, special check valve, long nozzle, and six-stage clamp-pressure control (low initial pressure aids venting during fast fill).

This machine, as well as two other new Nissei models at NPE, use beltless direct-drive servo motors, in which the ball screw is an extension of the motor spindle. Such a mechanism is said to be simpler, quieter, and cleaner (generating no dust) than a belt drive. It also reportedly has faster acceleration/deceleration response. Direct drive will appear at the show on Nissei’s high-speed ES200 (22 tons) and ES6000H (301 tons). Conventional belt drive will be shown on the new ES5000 238-ton electric machine.

In hydraulic-clamp machines, Van Dorn’s new Spectra Series replaces the mid-range HP Series. It comes in 500, 730, and 880 tons. The 500-tonner will be shown with a variable-speed pump drive that provides energy savings of 30-70%. Key features of the Spectra series are its modularity (it shares bases between sizes), wide platens, up to 15% lower height, and full tiebar support to allow for stack molds. Spectra models also use a reportedly unique three-port hydraulic valve that is said to offer the advantages of a servo valve without its sensitivity to contamination.

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.

The smallest machine at the show is the 2-ton, air-operated AB-300-4 from A.B. Machinery, Montreal. This new semi-automatic model has 1/4-oz shot capacity and is designed as a desk-style, “sit-down” unit with floor-pedal control. Electronic timers on the front panel regulate injection, clamping, and ejection.

NPE will be the North American introduction of Kawaguchi’s new standard line of toggle presses, the KX Series. The range is now 110-393 tons, and by fall it will span 55 to 720 tons. They boast larger and more rigid platens, longer strokes, new DV mixing screw, new PC-based EZ-2000 controller with real-time graphical shot displays, and new energy-saving digital hydraulic feedback control.

Join KraussMaffei for an insightful webinar designed for industry professionals, engineers and anyone interested in the manufacturing processes of PVC pipes. This session will provide a comprehensive understanding of the technology behind the production of high-quality PVC pipes: from raw material preparation to final product testing. Agenda: Introduction to PVC extrusion: overview of the basic principles of PVC pipe extrusion — including the process of melting and shaping PVC resin into pipe forms Equipment and machinery: detailed explanation of the key equipment involved — such as extruders, dies and cooling systems — and their roles in the extrusion process Process parameters: insight into the critical process parameters like temperature, pressure and cooling rates that influence the quality and consistency of the final PVC pipes Energy efficiency: examination of ways to save material and energy use when extruding PVC pipe products

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

The Powerline all-electric series from Ferromatik Milacron, Batavia, Ohio, is also moving up in size. Its newest and largest model is 935 tons (up from 750).

Gas assist: New components for hollow-core molding will be introduced by Alliance Gas Systems (Chesterfield Township, Mich.), Beaumont Runner Technologies (Erie, Pa.), Cinpres Ltd. (Ann Arbor, Mich.), GAIN Technologies (Sterling Heights, Mich.), and RIX Industries (Benicia, Calif.). In addition, Engel Canada Inc., Guelph, Ont., is demonstrating liquid silicone molding with gas assist. IMS Co., Chagrin Falls, Ohio, is newly distributing gas-assist equipment from NitroJection Corp. Bauer Compressors, Inc., Norfolk, Va., will also show gas-assist components.

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.

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.

Here are brief notes on some of the special-purpose machines and components to look for at the show (see our Show Guide for more details):

Microcellular foam: The MuCell process will be highlighted by Trexel Inc., Woburn, Mass., and its licensees—Arburg, Engel, Ferromatik Milacron, and Husky.

Addmix of London, England, is showing an “entry-level” coinjection system in which two materials are fed alternately into a single screw and barrel (similar to Ferromatik Milacron’s “mono-sandwich” approach).

New features will also be shown on benchtop machines from Mini-jector Machinery Corp., Newbury, Ohio. A 12-ton Model 55 will have an optional 2-oz shot capacity and oversized “V” mold. A 10-ton Model 70 will show several hardware and software updates.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

Look for micro-molders making parts of less than half a gram, as well as lots of big machines that have dainty footprints. Vertical machines will be present in force; gas assist and multi-material molding will be everywhere; and whole new machine lines will be launched into the marketplace. Molders looking for a bargain will face a daunting array of machines from unfamiliar Brazilian and Far Eastern vendors. And don’t miss the unusual or first-time demonstrations of special techniques like melt oscillation (Scorim process), hollow-parts molding (Die Slide process), gas counterpressure, gas assist paired with LIM or multi-material molding, and new water injection molding (it’s like gas assist without gas).
