AT NPE: Faster, More Compact Electric Press

By: Matthew H. Naitove 25. March 2015

The new Toyo Si-6 series of all-electric machines is one of three new developments being shown by Maruka USA, Pine Brook, N.J., at booth W303. Compared with Toyo’s Si-5 series, the new Si-6 series (pictured) is more compact, runs 33% faster, and has a redesigned clamp for easier maintenance. Larger models (the range is 55 to 1050 tons) also have redesigned injection units. The new System 600 controller runs 10X faster than the previous unit and offers added features. At the show, an Si-300-6 molded 32 plastic spoons in 4 sec, a full 2 sec faster than the previous model.

 

Maruka also showed Toyo’s compact, all-electric ET vertical machine, which now features enhanced controls for easier operation, faster response, and greater molding accuracy.

 

Two machines from Fu Chun Shin (FCS) of Taiwan were also on display. One was the new 160-ton FB-160 RSV hydraulic, two-material press. The other was the LA-SV series of two-platen hydraulic presses, brand-new to the U.S. and available in 550 to 4000 tons.

At NPE: Rotary Stretch-Blow Machine from China

By: Matthew H. Naitove 25. March 2015

Among the large contingent of Chinese machinery suppliers at the show this week, Tech-Long USA, Commerce, Calif., is showing off a new generation of rotary stretch-blow molders in booth S32001. The G5 model on display offers outputs up to 2400 bottles/hr per cavity with six to 32 cavities. It reportedly reduces energy use by 10-15% compared with previous machines and enhances compressed-air recovery by 40-55%. Improvements in speed result from use of servo motors instead of pneumatic stretch rods; an integrated gripper system for faster bottle discharge from the molds; and a new PLC with 15-in. touchscreen. Improved seals are said to reduce air-exhaust noise from 92 to 83 db. Keth Boss, CEO of Tech-Long Americas, says this is the fifth-generation machine from Guangzhou Tech-Long Packaging Machinery Co.

At NPE: New ‘Ultra-Fast’ Robots

By: Matthew H. Naitove 24. March 2015

Yushin America, Cranston, R.I., is introducing two Cartesian robots boasting “ultra-high speed” at booth W763. One is the HST-150S (photo), derived from the HSA high-speed models. It’s designed for less than 1-sec takeout times at a “very affordable price.” At the show it demolded 16 packaging frames in less than 0.5 sec for an overall cycle under 4 sec.

 

A brand-new introduction at the show is the HST-600DS robot, making its world premiere. It’s aimed at thin-wall, high-speed, stack-mold applications, and Yushin promises blazing speed.

At NPE: Toshiba Adds New Electric & Servo-Hydraulic Models

By: Matthew H. Naitove 24. March 2015

Toshiba Machine Corp., Elk Grove Village, Ill., kept its NPE plans under wraps until almost show time, but you can have a look at three new machines in booth W1563. One is a new 30-ton size of its high-performance, “super-fast” all-electric ECSX line. The EC30SX is running connectors on a 1.8-sec cycle.

 

Also new are two energy-efficient servo-hydraulic models (with pumps driven by servomotors), the 110-ton TiA220S (photo) and 390-ton ISGS390N. “We plan to roll out a complete lineup of servo-hydraulics later this year,” said U.S. and Canada sales manager Steve Cunningham.

 

All three machines sport the new V50 controller with touchscreen interface and up to 40 optional user-programmable outputs for customizing molding cells without additional OEM programming.

At NPE: Coinjection, LSR/TP Overmolding, PET Preforms & New Two-Platen Presses

By: Matthew H. Naitove 23. March 2015

You can’t miss booth W2703—it’s the biggest at the show (and at any NPE ever). There, several new injection machines and interesting technology demonstrations are on display by Milacron LLC, Batavia Ohio. Coinjection is the theme of two exhibits. One involves production of barrier cans of PP/EVOH/PP (photo) on a Ferromatik 280 press utilizing Kortec (now Milacron Co-Injection) technology. This Klear Kan system molds a barrier layer less than 1 mil thick that covers more than 99% of the part and can be controlled precisely in up to 96 cavities, Milacron claims. The can is retortable at up 130 C. At the show Milacron molded Klear Kans in four cavities in less than 8 sec.

 

In a second coinjection cell, a new Ferromatik 580 press molds 5-gal pails with 50% PCR (post-consumer recycle) in the center in under 15 sec. The new machine comes in nine sizes from 120 to 650 metric tons and is preconfigured for multi-component, mono-sandwich, cube, and coinjection capabilities. Electric, hydraulic, and hybrid drive options are available.

 

Another multicomponent demonstration utilizes a Fanuc Roboshot 150 overmolding LSR onto nylon to produce an automotive diaphragm. The system employed a new version of E-Multi auxiliary injection unit designed for LSR with a special screw and barel and ability to provide 22,000 psi injection pressure at 180 mm/sec injection speed. The mold from Roembke was mounted on a Varian turntable.

 

Meanwhile, a new press line, the Maxima Performance series, is a further development of the Maxima hydraulic two-platen platform. The new version (450 to 1000 m.t.) delivers 33% faster dry cycles, 70% lower energy consumption, the widest platens available in each tonnage range, and a precision greaseless clamp guided on linear bearings. Control of auxiliary equipment is integrated into the new Mosaic+ machine controller, which will become the global standard Milacron presses. Built on the previous Mosaic platform, it offers new features and options, fewer buttons, more intuitive user interface (21-in. touchscreen, and increased programming flexibility. Users can see auxiliary screens, such as mold temperature control, at the same time as the primary control screen.

 

Something else new from Milacron is Milacron’s entry into the PET preform market with the M-PET 300 servo-hydraulic press (photo) said to offer low energy consumption, leading-edge speed, and new options for post-mold handling—all at an attractive price/performance ratio. The system combines Milacron’s resources in machines, robots, hot runners, and molds into a single solution—though it can run other tooling as well.

 

Milacron is also demonstrating the ability to combine light weight with Class A surface by using MuCell foam technology from Trexel together with variotherm heat/cool alternating temperature control on a Magna T servo press.
