Injection Molding
What's New in Micro-Molding
Here’s a novel approach to the rapidly developing field of micro-molding. It’s a variation on two-stage injection—but with an in-line screw and plunger combination that delivers shot weights from 0.1 to 4.5 grams.
Read MoreLiquid Injection Molding Hits Its Stride
Liquid silicone rubber (LSR) has come a long way over the past two decades. From its roots in a few specialty applications where premium physical properties counted more than the premium price, this thermoset carved out a small but solid niche in the medical and automotive fields. Now, among a proliferation of new applications, that niche has begun to burst at the seams.
