Overview:
Customized Compression Rubber Mold Tooling for Silicone Products is precision-engineered tooling designed for high-volume production of silicone components. These molds are crafted using advanced CNC machining and EDM (Electrical Discharge Machining) processes to ensure micron-level accuracy. Primary materials include premium-grade tool steels like P20, H13, or 7075 aluminum alloys, selected for their durability, heat resistance, and ability to withstand repeated compression cycles. Our molds feature a proprietary non-stick surface coating, such as PTFE or nickel-PTFE hybrid, to enhance release performance, reduce flash, and extend mold lifespan.
As a certified OEM manufacturer with full in-house capabilities, we offer seamless one-stop service from design consultation to mold fabrication and post-production support. Our tooling guarantees fast turnaround times, consistent part quality, and optimized production efficiency for silicone rubber parts across medical, automotive, and consumer industries.

Surface Coating Options：
- PTFE (Polytetrafluoroethylene) Coating
– A non-stick, low-friction coating ideal for preventing silicone adhesion and minimizing flash formation.
– Enhances mold release efficiency and reduces downtime for cleaning.
- Nickel-PTFE Hybrid Coating
– Combines electroless nickel plating with embedded PTFE particles for superior wear resistance and non-stick properties.
– Extends mold lifespan in high-volume production (500,000+ cycles).
- Hard Chrome Plating
– Provides exceptional hardness (HRC 65-70) and corrosion resistance for molds exposed to abrasive silicones or harsh curing environments.
– Maintains dimensional stability under high-temperature compression (up to 250°C/482°F).
- Titanium Nitride (TiN) Coating
– A PVD (Physical Vapor Deposition) coating offering extreme surface hardness and thermal resistance.
– Reduces wear in high-pressure molding applications and improves resistance to chemical degradation.
Quality Assurance:
Our quality assurance framework integrates full-spectrum protocols, including ISO 9001:2015 and IATF 16949 certifications, to ensure compliance with medical, automotive, and industrial standards. Rigorous material inspection utilizes spectrometers (for alloy verification) and hardness testers (Rockwell C scale) to validate tool steel (P20/H13) or aluminum (7075-T6) specifications. Dimensional accuracy is guaranteed via CMM (Coordinate Measuring Machines) with ±0.005mm precision and surface roughness testers (Ra ≤0.4μm). Coating integrity is assessed through XRF (X-ray fluorescence) for PTFE/Ni-PTFE thickness and adhesion tests per ASTM D3359. For durability, molds undergo thermal cycling trials (up to 250°C) and pressure simulation (200+ tons) to validate cycle life (500K+ for steel molds). Our in-house NDT (non-destructive testing) and 3D scanning ensure defect-free tooling, while certified material traceability and DFM (Design for Manufacturability) reports are provided. All processes align with FDA 21 CFR Part 820 for medical-grade silicone applications.
