Low temperatures assist rheometers
U.K.-based Malvern Instruments Ltd. has introduced a range of low-temperature control options for the Malvern Rosand brand of capillary rheometers.
High-pressure capillary rheometry is a well-known method for simulating the processing conditions of molten polymers at high temperatures. Malvern's new low-temperature control options enable rheometry to be applied to a larger range of materials.
The options use cooling coils with a fluids circulator for measurements from 11°-122°F. An option for cryogenic cooling uses liquid nitrogen for even lower temperatures.
The options are compatible with the full range of capillary dies for Malvern Rosand rheometers RH7-DRH10-D and RH2000.
The company is based in Malvern, England. The U.S. unit, Malvern Instruments Inc., is in Southborough, Mass.

In-mold label system uses static electricity
Simco Industrial Static Control is touting its Chargemaster electrostatic charging system for in-mold labeling, using static electricity to hold the label securely in the tool.
There are two methods for charging the label with static electricity. The conventional way is to mount the charging applicator directly behind the label on the end-of-arm tooling of the robot. The robot controller activates the static charge, and the tool's vacuum is turned off so the label adheres to the mold cavity.
A simpler method does not require mounting the high-voltage charging components on the EOAT. An anti-static foam is cemented to a grounded metal plate on the robot's tool fixture. Suction cups are fixed to the foam, flush with the work surface. The robot picks the label up using suction, molding it flat against the foam. The label is passed by a static-charging bar mounted externally to the press, then placed into the mold cavity.
Simco of Hatfield, Pa., is touting static electricity as better than using vacuum ports in the mold, which the firm said increases tool costs and can cause ``pimples'' in the graphics on the surface of the part.

PlastiQuote analyzes molding work, costs
PlastiQuote software is designed to do detailed cost analyses for injection molding, and it generates a quotation cover letter at the end.
The software also creates a PQ Vision Report, a bill of materials and work instructions for manufacturing. Database tables covering areas such as customers, resins and machines can be customized to represent details of your business.
Jeff Barboza, president of PlastiQuote LLC in Somerset, Mass., has a master's degree in plastics engineering from the University of Massachusetts at Lowell and more than a decade of industry experience.

Pellbow lessens dust during pellet delivery
Lancaster, Pa.-based Pelletron Corp. introduced the Pellbow - a pipeline elbow that it said minimizes the dust and streamers formed when resin pellets come to a sudden turn.
The maker of bulk-materials-handling equipment created a streamlined pocket shape by enlarging the bend at the incoming point, which produces a soft layer of pellets just before they hit the elbow. That soft layer deflects incoming pellets toward the outlet, minimizing degradation, the company said.
The Pellbow comes in stainless steel, aluminum and cast iron.
Also new from Pelletron is FlowEnhancer, a special bow-off section that reduces conveying air in a controlled way, increasing the capacity and reducing the velocity of pneumatic conveying systems. The air is filtered and released to the atmosphere.
A redesigned P-600 DeDuster offers a split design that creates a low profile for easier installation in factories with limited head room.

QuickTool Express gives instant quotes
Atlanta-based Quickparts.com Inc. launched its QuickTool Express, which creates instant online quotes for injection molded parts.
The user uploads his own unique computer-aided design data and defines the material, color, internal and external finish and lead time. Then, with the click of a button, the system calculates a custom quote for tooling and per-part pricing.
The user can perform unlimited ``what-if'' scenarios, including multiple tools, materials and quantities.
QuickTool Express is designed for simple injection molded parts, but the company also offers QuickTool Pro for design engineers making parts with more complex geometries.
