Tooling Surface Coatings:
- Nickel Plating: Nickel plating is applied to the tooling to enhance surface hardness and improve resistance to corrosion and wear. This coating ensures the tooling lasts longer and maintains precision throughout multiple production cycles, reducing the need for frequent maintenance.
- Chrome Plating: Chrome plating offers superior hardness and excellent wear resistance for tooling. This coating helps minimize friction, ensuring smooth and consistent mold performance, even under high-volume production, while also providing a high-quality, polished finish.
- Anti-Corrosion Coating: Anti-corrosion coatings are applied to protect the tooling from rust and degradation due to exposure to moisture and chemicals during the molding process. This ensures longevity and stable performance, especially in environments with fluctuating humidity or exposure to harsh materials.
- Teflon Coating: Teflon coatings provide a non-stick surface that reduces the friction between the silicone material and the mold. This results in easier mold release, cleaner finishes, and a more efficient molding process, while also preventing material buildup that could affect the precision of the tooling.
Quality Assurance:
The manufacturing process begins with design validation (DFM analysis via 3D CAD/CAM), followed by high-precision CNC machining of hardened steel or aluminum mold bases to ±0.05mm tolerances. Advanced compression molding employs heat-resistant LSR/HTV silicone rubber, cured under controlled temperature/pressure cycles for optimal density and dimensional stability. Post-processing includes EDM/texturing (Ra ≤0.2µm) and QC inspection using CMM, durometers, and tensile testers. Our facility is ISO 9001:2015 and RoHS-certified, equipped with automated hydraulic presses, spectral analyzers for material compliance, and aging test chambers for lifecycle validation. Rigorous batch testing ensures defect-free molds with 50k+ cycles, backed by full traceability and PPAP documentation for industrial-grade reliability.
