The YIZUMI LSR Series is a specialized liquid silicone injection molding machine designed to meet the growing demand for environmentally friendly, impact-resistant, and heat-resistant products. This dedicated machine integrates a professional LSR injection unit with the SK platform to handle the unique properties of liquid silicone resin (LSR), which is characterized by good liquidity, low viscosity, fast solidification, and higher thermal expansion coefficients. The machine utilizes a two-part material delivery system with A and B components in a 1:1 ratio for precise vulcanization and solidification processes.
Engineered for high precision applications in medical, industrial, and consumer products, the LSR machine offers exceptional stability, reliability, and repetition accuracy to maximize product yield. The system incorporates advanced features like pneumatic secondary metering, water-cooled injection nozzles, and comprehensive temperature control interfaces to ensure consistent quality in manufacturing silicone products ranging from baby bottle nipples and medical devices to industrial components and consumer electronics accessories.


Features
Fully pneumatic secondary metering system with precise A/B ratio control - Energy-efficient and pollution-free operation with manual correction capability and ratio error less than 3% for consistent material mixing
Specialized mixing screw designed for silicone processing - Mixed compounds at screw front end ensure complete blending of A and B components while preventing adhesion, yellowing, or blackening issues
Water-cooled pneumatic injection nozzle with leakage prevention - Prevents liquid silicone leakage and blocks mold temperature transmission to nozzle, avoiding curing reactions of mixed LSR in the nozzle
Advanced silicone leakage-proof design with sensitive seal rings - Specialized sealing system adapted to high liquidity of silicone resin with additional seal and wear rings to prevent rear-end leakage and material waste
Integrated vacuum pumping system and temperature control interfaces - Standard vacuum procedures improve gas discharge effects and prevent defects while separate heating unit sockets provide convenient temperature management
Expanded tie bar space and comprehensive auxiliary equipment compatibility - Increased 460x370mm tie bar spacing accommodates larger molds with integrated D522 liquid silicone feeder and maintenance-free design for reduced downtime
