Sequential Gating & Gas Assist Team Up for the First Time
Two fast-growing injection molding techniques—valve-gate sequencing and gas-assist technology—have come together in one application for what is said to be the first time. The part that united the two technologies was a 14 x 30 in. x 120-130 mil computer panel being converted to plastic from metal by Hewlett-Packard Co. in Roseville, Calif. It posed a number of process problems that were best solved by combining the two procedures.
