About Used Used LSR Injection Molding Machines
Liquid Silicone Rubber (LSR) injection molding machines are specialized for processing two-component silicone materials that cure in a heated mold. LSR molding (also called silicone injection machine technology or soft plastic injection molding) produces parts with exceptional biocompatibility, heat resistance (-60°C to 200°C+), chemical resistance, and flexibility. LSR parts are used in medical devices, baby products, automotive seals, kitchen utensils, and wearable electronics.
LSR injection machines feature specialized metering and mixing systems, cold-deck molds, and precise temperature control. The material is pumped as a liquid from drums, mixed at a precise ratio, and injected into a heated mold where it cross-links into a solid elastomer.
Meadoworks stocks used LSR injection molding machines from Engel, Arburg, Boy, Nissei, and Krauss Maffei. Contact us at 800-323-0307 for soft plastic injection molding machine availability.

Frequently Asked Questions
What is LSR injection molding?
LSR (Liquid Silicone Rubber) injection molding uses a two-component silicone material that is mixed and injected as a liquid into a heated mold where it cross-links into a flexible, durable elastomer. Unlike thermoplastic injection molding, LSR uses a cold-deck system and heated mold. The resulting parts are biocompatible, heat-resistant, and chemically inert.
How much does a used silicone injection machine cost?
Used LSR/silicone injection molding machines typically range from $50,000-$200,000+ depending on tonnage, brand, metering system, and condition. The specialized metering and pumping equipment adds cost compared to standard injection molding machines. Contact Meadoworks at 800-323-0307 for current pricing.
