Description:
Our Compression Mold Tooling for Silicone Parts is designed for high-volume production, ensuring exceptional precision and repeatability. Utilizing state-of-the-art CNC machining and EDM (Electrical Discharge Machining) technologies, we achieve micron-level accuracy, meeting the most demanding industry standards.
Constructed from premium-grade tool steels such as P20, H13, and 7075 aluminum alloys, our molds are engineered for superior durability, heat resistance, and extended service life, withstanding repeated compression cycles without compromising performance. To further enhance mold efficiency, we apply advanced non-stick surface coatings such as PTFE and nickel-PTFE hybrids, which significantly improve part release, minimize flash formation, and extend mold longevity.
As a certified OEM manufacturer, we provide a comprehensive one-stop solution, covering design consultation, precision mold fabrication, and post-production support. Our expertise ensures short lead times, consistent part quality, and optimized production efficiency, making our tooling the ideal choice for medical, automotive, and consumer product applications where precision, reliability, and performance are critical.

Quality Assurance:
Quality Assurance (QA) for compression mold tooling in custom silicone parts encompasses design validation (via CAD/CAE simulation), material certification (platinum-cured LSR verification), precision machining audits (maintaining ±0.002″ tolerances), and production-ready testing (cycle endurance, flash prevention, and demolding efficiency). Certifications require ISO 9001:2015/IATF 16949 compliance with mold flow analysis reports and RoHS documentation. Critical inspection equipment includes Mitutoyo CMMs for 3D GD&T verification, Shore A durometers for hardness validation, Instron tensile testers for material performance, Keyence VR-5000 non-contact profilometers for surface finish (Ra ≤ 0.4µm), and vision projection systems for critical dimension inspection. PPAP documentation and cavity pressure/temperature monitoring during validation runs ensure process capability (Cpk ≥1.67) for medical, automotive, or aerospace applications.
Production Process:
The manufacturing of compression mold tooling for silicone parts follows a precise and systematic process to ensure high accuracy, durability, and efficiency. Below are the key steps:

– Utilize DFM (Design for Manufacturability) and mold flow analysis to optimize mold design for efficiency and longevity.
- Material Selection & Preparation
– Choose high-performance tool steels (e.g., P20, H13) or 7075 aluminum alloys based on mold durability, thermal conductivity, and production volume.
– Conduct precision material cutting and pre-treatment to enhance structural integrity.
- CNC Machining & EDM Processing
– Perform high-precision CNC milling, turning, and grinding to shape the mold base and cavities.
– Apply EDM (Electrical Discharge Machining) and Wire Cut EDM for intricate details and fine surface finishes.
- Heat Treatment & Surface Hardening
– Strengthen the mold components using heat treatment techniques, such as nitriding or vacuum hardening, to improve wear resistance and longevity.
– Apply polishing and fine surface finishing to ensure smooth mold cavities.
- Surface Coating Application
– Enhance mold performance with specialized non-stick coatings such as PTFE, nickel-PTFE hybrid, or ceramic coatings for improved release, reduced flash, and extended mold life.
- Assembly & Final Precision Adjustments
– Assemble mold components, including core, cavity, ejector system, and cooling channels.
– Perform precision fitting and alignment adjustments to ensure tight tolerances and optimal functionality.
