Liquid Silicone Rubber (LSR) applications are gaining popularity among injection molders to meet the needs of customers as medical, technical, and automotive brands expand their product portfolio to take advantage of this material’s unique properties. Due to rising material costs and the inability to use regrind, the benefits of direct gating with runnerless molding have become more compelling. For molders considering a transition to this niche market, LSR can be a challenging manufacturing process and learning experience due to the material’s viscosity characteristics and unique chemistry. Where thermoplastic injection molding accomplishes runnerless molding with a hot runner, LSR injection molders accomplish the same goal with a cold deck.
• The requirements and concepts of LSR injection molding
• How LSR injection molding differs from traditional thermoplastic injection molding
• The benefits of runnerless molding and reducing waste with cold deck technology
• Key considerations and unique features required by cold deck design for successful runnerless molding
