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
Thermoplastics and Liquid Silicone Rubber (LSR)
Reply
Plastics are either organic or semi-organic materials that have (as their main attribute) a very large molecular weight. These very large molecules, or macromolecules, give them their distinct properties and material behavior, when compared to other materials used in manufacturing … Continue reading
Why Making Parts From LSR is the ONLY Option
Injection molding of Liquid Silicone Rubber (LSR) has existed and evolved over the past 20 years. Due to the thermosetting nature of the material, LSR injection molding requires special treatment, such as uniform distributive mixing; in addition, the material must … Continue reading
