For 2-Shot injection molding, a multi-shot mold is needed. There are several types of multi-shot molding available, such as over-molds, core-back, and multi-station molds. The right mold selection depends on part geometry, volume, quality, and molder capacity/capability. In a transfer … Continue reading

Multi-Station Molds: Rotational Molds
In 2-Shot injection molding, a polymer is injected over a molded plastic insert to combine the best features of different materials while reducing or eliminating additional assembly operations. This reduction or elimination of post-processing steps is one of the biggest … Continue reading
Vulcanization of LSR in the Injection Molding Process
For design and processing of Liquid Silicone Rubber (LSR) parts, the curing and respective flow behavior must be known. The two components begin to cure immediately after mixing. During curing the chemical bonds formed release heat which causes a temperature … Continue reading
