LSR molding equipment

M.R. Mold & Engineering Corp., a mold manufacturer specializing in the design and manufacture of molds for liquid silicone rubber, introduced three new products at Plastec West. The company developed these products for its own use but found a market for them generally in the molding of LSR.

A new type of pneumatic control for valve-gated cold decks was introduced, and has several unique features such as a Windows-based platform, convenient touch screen for data input, and models available to control up to 32 zones.

A pneumatic ?stuffer box? for LSR/gum stock silicone/rubber is also a new product. Features include stainless steel and anodized aluminum construction for medical applications, and 27-cu-in material capacity. It?s ideal for prototyping and short-run production, and mounts easily on any machine. It?s designed to allow for quick cleaning and material changes.

The company also introduced a silicone vacuum seal for parting-line sealing of silicone and rubber molds. It has a tapered body to avoid being pinched in the parting line, and eliminates the compression set seen when using traditional O-rings. It?s designed with locking ?feet? to retain itself in the seal groove. The company also provides mold tryouts and qualifications with in-house LSR molding capabilities.
