Compounders: Now You Can Monitor Color Inside the Extruder!
If you're compounding colors, there's no need to keep running pellet samples to the lab for periodic quality checks.

Large Two-Platen Presses Gain Speed and Flexibility
An improved line of large two-platen injection presses offers new sizes plus greater speed, educed maintenance, more operator-friendly design, and added flexibility for a range of molding requirements.

News in Small Injection Presses, Robots, Gas Assist and IML
Advancements in hydraulic presses and servo robots were unveiled by Arburg GmbH at its annual Technology Days conference and technical exhibition in March at its headquarters in Lossburg, Germany.

Composites: New Rapid Molding Technologies and Unusual Reinforcements at Paris JEC Show
New molding technologies seen at the JEC Composites Show in Paris in April promise dramatically faster cycles than are achievable with autoclaves or RTM. One novel technique rapidly heats and cools a thin tool by "floating" it on a flexible bladder—similar to a water bed—that is flooded with heat-transfer fluid.

How to Address Cooling System Woes
Anyone who operates a molding plant knows three things it cannot run without: raw material, electrical power, and cooling water.

MIDs Make A Comeback
3D molded interconnect devices were supposed to be the 1980s' breakthrough for plastics in electronics—but they flopped. New processes that make market entry faster, simpler, and less costly have recharged MIDs' prospects.

Take Good Care of Your Extrusion Pressure Transducers
Eight tips on installing and maintaining melt-pressure sensors in your extruder will help them last longer and give you fewer problems.

Total Mold Business Index for May 2005: 50.4
