Compact AB Liquid Silicone Rubber Molding Machine Supply Vertical Liquid Silicone Rubber Solid-to-Liquid Conversion Equipment

An LSR injection molding machine is a specialized piece of equipment used to produce parts from liquid silicone rubber (LSR) through a process called liquid injection molding (LIM). These machines are designed to handle the unique properties of LSR, which is a thermoset material that requires specific processing conditions to achieve proper curing.

• Dedicated LSR Injection Unit: Designed to handle the low viscosity of liquid silicone rubber
• Meter Mixing System: Precisely mixes two-part LSR in specific ratio (usually 1:1)
• Static Mixer: Combines components to initiate the curing process
• Heated Mold: Triggers chemical reaction that cures material into solid rubber
• Precise Temperature Control: Crucial for proper curing
• Fast Cycle Times: Can be demolded before full curing, especially for thicker parts

• Produces complex geometries and thin-walled sections
• Operates at lower injection pressures than thermoplastics
• High precision and repeatability for tight tolerances
• Withstands wide temperature ranges
• Excellent material properties including flexibility and strength

• Medical: Seals, gaskets, catheters, breathing masks
• Automotive: Seals and gaskets
• Electronics: Keypads, connectors, insulators
• Consumer Goods: Baby bottle nipples, kitchen utensils
