Read MorePrecision Molder Takes on LSR
Liquid Silicone Rubber (LSR) injection molding makes up just 10% to 15% of U.S. medical or automotive applications that are also served by high-consistency silicone rubber (HCR), EPDM, latex, natural rubber, TPEs, flexible PVC, and even porcelain ceramic. Nonetheless, LSR molding is attracting growing interest (see Learn More), enough to prompt the formation of a new division dedicated to LSR by GW Plastics in Bethel, Vt.

For some problems the solution is to be soft but also be strong.
Read MoreCoatings Give Aluminum Molds Cost/Performance Edge Over Steel
New cost-effective technologies are designed to make aluminum an attractive alternative to tool steels in a range of plastics molding processes. One method uses a plasma technique to convert the aluminum surface into a hard, dense, wear-resistant ceramic. Another approach uses electro-deposition to apply a surface coating with high hardness, corrosion resistance, and chemical resistance.
