Understanding Silicone Transferr Molding

Silicone transfer molding is a specialized produced process designed to encapsulate electric contents with liquid silicone rubber (LSR). In a typical cycle, a pre- placed contexent or substrate is positioned inside a heate mold cavity. Liquid silicone is then injelted from a separate chamber ditiumgh a transfer channel (sprue or runner) into thee cavity, where it flows around thee contene canut to form a protective, expexelle layer.
