New Novatec loaders provide clear view
Novatec Inc. introduced its see-through GlassVu loaders and receivers at Plastics Encounter at Antec 2007.
The cylindrical loaders, receivers and machine-mount hoppers all have large, wrap-around midsections made of glass to give a clear view of the filling process. Loaders and receivers have slanted lids that allow full access to the interior, without disturbing material or vacuum lines.
Baltimore-based Novatec also made some design changes to improve material discharge, access for draining and cleanout and simplified installation.
Flat bottoms provide large openings for resin evacuation. Slanted bottom panels inside the loaders and receivers are pneumatically opened and closed, so they function as slide-gate valves for efficient discharge. An infrared sensor shines across the discharge opening to provide ``full'' or ``demand'' signals to the controller.
Novatec also has designed a glass hopper base. The hopper is contained within a sturdy frame. But instead of being bolted in, the hopper pivots out of the frame - like the filter unit on a coffee maker — for easy drainage of residual material.
Chuck Morgan, resin handling business director, said the straight walls of the loaders and receivers extend all the way down to the discharge area, eliminating the narrow section of cone-shaped units that can cause bridging problems.

Posttech marketing Web-based software
Posttech LLC of St. Joseph, Mich., is marketing its process monitoring and control software that company officials claim is truly open-source and Web-based.
The software works with off-the-shelf hardware, with no need to purchase proprietary hardware, according to President Rich Post.
Posttech specializes in plastics manufacturing operations. There is no annual maintenance contract or licensing costs, Post said. Other modules can be added as the company grows or requires additional capability.
Sample screens can handle system administration, scheduling, inventory reporting, product information, machine data, job tracking and other functions, all in real time.
Post has worked at Milacron Inc., Syscon-PlantStar and Mattec Corp. His partner, Patrick McCrevan, also worked at PlantStar.

Asaclean enhances purging compound
Asaclean-Sun Plastech Inc. says it has enhanced its strongest purging compound.
The Parsippany, N.J., firm claims the new Asaclean EX grade has more cleaning power while leaving behind 30 percent less residue. Purging procedures remain the same and the operating temperature is still 390-680° F.

Monitoring system integrates processes
Mattec Corp. said its ProHelp EPM Version 7.1 gives the same, real-time shop-floor monitoring and control for continuous processes, such as sheet, profiles, blown film, compounding and thermoforming, as that achieved for cyclical operations like injection molding.
``For the first time, manufacturers can easily integrate all the processes within a factory,'' said Mattec President Mick Thiel. ``Even companies operating very different kinds of machinery can now get total continuity in production and process monitoring and reporting.''
ProHelp continuously monitors every machine and alerts users to critical changes in process conditions, such as speed, temperature or pressure, so the process gets corrected before the machine produces bad parts.
Continuous processes need their own set of functions and parameters. Extrusion, for example, must be monitored for screw revolutions per minute, melt temperature, screen pressure, line speed and other data.
Mattec is based in Loveland, Ohio.

EDI coating system reduces setup time
Extrusion Dies Industries LLC has introduced its Modular Coating System, a complete slot-die-coating station, including all components, from idler roll to backing roll.
EDI said the MCS eliminates hours of setup in switching from roll to slot-die coating. Users of conventional roll coating get greater access to the advantages of slot-die systems, the company said.
The MCS rolls into place on nearly any commercial coating line, so operators of roll-coating systems can switch readily between roll and slot-die coating, or use slot die-coating on a trial basis.
EDI is based in Chippewa Falls., Wis.

Great Western offers gravity-flow sifter
Great Western Manufacturing Co. Inc. of Leavenworth, Kan., has introduced the stainless-steel Tru-Balance, a gravity-flow atmospheric sifter.
All contact surfaces are welded to eliminate crevices, rivets, and nuts and bolts. A boxless design provides quick access for removing and replacing the sieves.

Dow adds ionomers to polyolefins line
Dow Chemical Co. has added ionomers to its line of Amplify functionalized polyolefins.
Amplify IO polymers are directed at demanding applications in food packaging, medical packaging, molded goods and impact modification of nylon. Dow of Midland, Mich., claims the new ionomers offer very good optical properties, high melt strength, impact and scratch resistance, and adhesion to polyethylene, metals, glass and nylon. Dow says they can be processed by injection molding, and as films and coatings.
The new ionomers, based on ethylene/acrylic acid copolymers, are available in various sodium and zinc versions.

Mitsubishi introduces biodegradable plastic
Mitsubishi Chemical Corp. of Tokyo has developed a new biodegradable plastic it claims can outperform polylactic acid.
The new material, tradenamed GS Pla, is a polybutylene succinate. Mitsubishi says it completely biodegrades and does so faster than polylactic acid in soil. It is flexible, has high heat-seal strength and is permeable to oxygen and moisture. It is more flexible and has higher tensile elongation and notched Izod impact strength than polylactic acid, Mitsubishi claims.
GS Pla can be injection molded, cast as a film, vacuum formed or blow molded. It recently was introduced in Japan, where it is finding use in mulch films, nursery pots and other agricultural applications. Its ability to form fibers suggests nonwovens and synthetic papers as potential uses. Mitsubishi's MC Research & Innovation business unit in Redondo Beach, Calif., is spearheading introduction of GS Pla in North America.
Mitsubishi aims eventually to make the polymer even more environmentally friendly by basing much of the components on biological feedstocks such as corn.
