GLOUCESTER, MASS. - Dynisco Inc. of Sharon, Mass., said a Kona Single-Axis Valve Gate is designed for molding parts with excellent cosmetic finish, materials with foaming agents and gas-assisted injection molding. An open pipeline design has a large gate orifice for a minimum amount of shear stress. The valve pin is separated from the flow channel, so there is no obstruction to block the material. A large gate orifice also means minimal molded-in stresses.
The company said its Kona CAD library, which gives drawings of all Kona hot runner components, is now available on CD-ROM and 31/2-inch diskettes.
Kona products are made in Gloucester.

Arburg of Newington said the screw has a 20 percent higher plasticating capacity, allowing shorter cycle times. Better mixing also means barrel temperatures can be reduced, and molders can save on colorant costs, the company said.
