Custom Silicone Rubber Injection Molding Service For Your Business
Liquid silicone rubber injection molding parts have the feature of durability with good tensile strength and are used to high volume, tight tolerance. Therefore it is widely used in various industries especially for medical parts.
Here are the advantages of liquid silicone rubber:
Excellent insulating properties, good for tight tolerance/precision components.
Good tensile strength with high/low-temperature extremes.
Good resistance for water, oxidation also some chemical solutions like acids.
Expertise in Complex Silicone Tooling
- Multi-cavity mold design for LSR
- Cold runner & valve gate systems for waste-free molding
- Overmolding on thermoplastics or metal inserts
- Insert alignment accuracy up to ±0.01 mm
- High-transparency lens-grade silicone molding
All molds are tested in-house and validated for dimensional accuracy, mold flow, and part performance.
Material Capabilities
We work with a wide range of medical-grade and specialty silicone materials, including:
- Platinum-cured liquid silicone rubber (LSR)
- FDA & ISO 10993 certified materials
- Optical-grade silicone with high transparency
- High-elongation, UV- and yellowing-resistant compounds
- Hardness from Shore A 10 to 80
Our engineers will recommend the optimal material based on your product’s function, clarity, mechanical strength, and regulatory needs.
