Liquid silicone rubber molding uses two-part liquid systems that cure rapidly under heat. This advanced process produces high-precision components with exceptional material properties. You get superior dimensional accuracy and surface finish compared to conventional silicone processing.
Platinum-catalyzed addition-cure systems eliminate reaction byproducts during curing. This creates cleaner parts with better mechanical properties. The materials cure quickly and completely without requiring post-cure operations.
Liquid systems flow easily into complex mold geometries. You achieve excellent detail reproduction and consistent wall thickness distribution. The process handles thin-walled sections and intricate features that challenge other molding methods.
How Do You Set Up Equipment for Liquid Silicone Rubber Molding Success?
Specialized injection molding equipment handles liquid silicone systems effectively. Positive displacement pumps meter both components accurately. Static mixers ensure homogeneous blending before injection into molds.
Temperature control prevents premature curing during processing. Keep material temperatures below activation points until injection. Heated molds cure materials rapidly once the injection is complete.
Consider these equipment requirements:
- Precision metering systems for accurate ratios
- Temperature-controlled material handling
- Static mixing for homogeneous blending
- Heated molds for rapid curing
- Automated controls for consistent processing
System cleanliness prevents contamination and cure inhibition. Flush lines regularly with appropriate solvents. Store materials in clean, dry conditions to maintain quality.
What Applications Benefit Most from Liquid Silicone Rubber Molding?
Medical device manufacturing extensively uses liquid silicone rubber molding for biocompatible components. The process creates seals, gaskets, and implantable devices meeting stringent regulatory requirements. Sterilization resistance and chemical inertness make liquid silicone perfect for medical applications.
Automotive applications leverage silicone’s temperature resistance and durability. Components include gaskets, seals, and vibration dampeners. The material withstands engine compartment conditions and maintains sealing integrity through temperature cycling.
Consumer electronics benefit from silicone’s electrical insulation properties. Keypads, gaskets, and protective covers use liquid silicone for reliable performance. The material provides excellent environmental sealing and tactile response.
