Product Description

BETTER 1600R2 Cold Runner LSR Molding Machine 160 Ton Servo for Reducing Silicone Waste

The BETTER 1600R2 is a vertical rotary liquid silicone rubber (LSR) injection molding machine built around cold runner technology. By keeping the silicone at low temperature inside the runner while the mould is heated to trigger vulcanisation, it dramatically reduces silicone waste and delivers high-precision, high-efficiency automated production.

Key Advantages

Cold Runner System Reduces Silicone Waste – the runner stays cold so silicone is not prematurely cured, cutting material waste significantly.
30-50% Electricity Savings – the servo-driven design and precise thermal control deliver obvious energy savings.
High-Precision Automated Production – precise A/B metering, mixing and injection deliver stable, repeatable high-quality parts.
Vertical Rotary Table – supports insert molding and multi-station production for higher efficiency.

Working Principle

Liquid silicone injection molding machines employ cold runner technology. After precisely blending the low-temperature liquid A and B components of silicone in the correct ratio, the mixture is pressurised by a screw and injected into the high-temperature mould cavity. Under the mould's heating action a rapid chemical cross-linking reaction occurs, curing the material into shape. This achieves high-precision, high-efficiency automated production.

Raw Material Delivery & Mixing: Component A (catalyst) and Component B (cross-linking agent) are stored separately and metered in a fixed ratio into a static mixer.
Injection Molding: The mixed liquid silicone is pushed through a non-return valve into the cold runner system, which keeps the silicone cool to prevent premature curing.
High-Temperature Vulcanisation: Inside the heated mould the material undergoes a rapid thermal curing cross-linking reaction and solidifies into an elastic, stable silicone product.
Pressure Holding & Cooling: Constant pressure ensures dimensional accuracy; the mould then cools and opens to release the cured product.

Differences from Conventional Injection Molding Machines

Raw Material State: Liquid raw materials versus solid raw materials.
Forming Method: Thermosetting chemical cross-linking versus cooling solidification.
Temperature Control: Cold runner keeps silicone low while the mould heats to vulcanise.
