Advanced Silicone Mold Manufacturing Technologies
We design and machine custom silicone molds tailored for both Liquid Silicone Rubber (LSR) injection and High Consistency Rubber (HCR) compression molding.
Liquid Silicone Rubber (LSR) Cold Runner Molds
Liquid silicone injection molding requires highly sophisticated mold making. Our in-house workshop engineers precision multi-cavity LSR molds equipped with cooled runner blocks and needle valve systems. This prevents premature vulcanization in the feed runners, providing flashless, scrap-free production cycles with tight tolerances.
- Cold deck valve gate technology eliminates sprue material waste
- Micro-precision cavity polishing ensures pristine optical and surface quality
- Designed for fully automated, high-speed injection molding lines
- Perfect for medical devices, baby products, and food-grade components
High Consistency Rubber (HCR) Compression Molds
For solid silicone rubber grades, we manufacture rugged compression and transfer molds from premium tool steel. Our mold designs incorporate precise thermal expansion calculations, strategic air venting channels, and land areas engineered to simplify deflashing and guarantee dimensional stability under heavy hydraulic press loads.
- Economical mold making setups for low-to-medium series production
- Accommodates high durometer and heavy-duty industrial silicone parts
- Precision-machined parting lines eliminate unwanted parting line flash
- In-house hardened steel plates resist wear during long production runs
Why Choose Silicone Rubber Polymer?
Silicone rubber features a unique mineral-based siloxane backbone (Si-O) that provides properties unmatchable by traditional organic elastomers.
High Thermal Resilience
Withstands continuous temperatures from -60°C up to +230°C without loss of flexibility or mechanical degradation.
Inert & Biocompatible
Non-reactive with chemicals and bodily fluids, making silicone the preferred choice for medical and food contact uses.
High Flexibility & Non-Sticky
Non-sticky surface behavior and superior elasticity allow smooth release of molded parts and long fatigue life.
Weather & UV Resistance
Inherent resistance to ozone, ultraviolet light, and environmental aging guarantees long-term durability outdoors.
Our Silicone Mold Tooling Mechanism
A controlled engineering lifecycle that guarantees your custom silicone mold delivers exact part geometry from trial to mass production.
Product CAD Design
Analyzing 3D CAD models for draft angles, wall thickness consistency, and parting line placement.
Shrinkage Calculation
Applying exact silicone volumetric shrinkage factors (2% to 4%) to the mold cavity dimensions.
CNC & EDM Tooling
High-speed CNC milling and EDM wire spark erosion of hardened mold steel cavities.
Mold Trial & Baking
Conducting press trials, thermal curing, and post-baking validation of sample silicone components.
