Gain Technologies

A new line of separate pressure generators, high-pressure compressors, and gas controllers, which can be combined into a system that grows as the customer’s business expands, comes from Gain Technologies, Shelby Township, Mich.

A novel combination of internal and external gas assist is the secret to injection molding a large panel that is both structural and requires a highly cosmetic surface.

Commercial applications in hollow-part molding with water—or water and gas—are starting to accelerate. They are driven by recent enhancements of process technology, equipment, and materials.

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.

 Two variations on gas-assist injection molding were presented in papers at the Molding 2002 Conference held in New Orleans in March.

The abundance of injection molding news at this year’s show is staggering.

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.
