Overview:
Our factory specializes in OEM Nitriding Compression Rubber Molding Molds, meticulously crafted from high-performance materials such as tool steel, stainless steel, or aluminum alloys. Utilizing advanced CNC machining, heat treatment, and precision grinding, we ensure exceptional durability, tight tolerances, and long-lasting performance for high-volume production. Our one-stop service covers design support, prototyping, mold testing, and mass production, providing a seamless experience for your rubber part manufacturing needs.
Nitriding enhances the durability and wear resistance of the molds, significantly extending tool life and improving the consistency of molded parts. This advanced surface treatment results in increased hardness, superior corrosion resistance, and reduced friction, making it ideal for high-demand compression molding applications. Trust our expertise in delivering cost-effective, high-quality solutions customized to your exact requirements.

Benefits of Our Mold:
- Enhanced Surface Durability via Plasma Nitriding
Ion-nitrided tool surfaces achieve 1,100–1,300 HV hardness, reducing abrasive wear by 60% in high-pressure vulcanization cycles (up to 300°C/4,500 psi), ensuring >500,000-cycle lifespan for silicone/rubber compression molding.
- Precision-Tuned Thermal Management
FEA-optimized conformal cooling channels maintain ±2°C mold-face temperature uniformity, eliminating flash formation and curing inconsistencies across complex geometries like undercuts and micro-textured cavities.
- Tight-Tolerance Tool Fabrication
Multi-axis CNC/EDM machining delivers ±0.005mm dimensional accuracy, critical for medical-grade seals and automotive gaskets requiring ISO 3601-3 compliance and leak rates <0.01 sccm.
- Corrosion-Resistant Material Integrity
H13 tool steel pre-hardened to 38–42 HRC with CrN PVD coating resists sulfur-containing rubber compounds, minimizing pitting and extending PM intervals by 3x compared to non-nitrided molds.
Quality Assurance:
Lingshan Tech’s QC framework integrates material validation (spectrometry for H13 tool steel composition), dimensional precision (±0.003mm via Mitutoyo CMM and Keyence LM-3000 3D scanners), and surface integrity analysis (plasma nitrided layers tested for 1,200–1,400 HV hardness using Rockwell/Clemex microhardness testers). Environmental simulations (thermal cycling -50°C/+300°C, humidity chambers) validate corrosion resistance against sulfurized elastomers, while ZEISS SEM-EDS detects micro-pitting. Compliance is ensured through ASTM E384/E18 standards, IATF 16949:2016 for automotive tooling, and NADCAP-accredited material testing, supported by automated optical inspection (AOI) for cavity geometry and ISO 9001:2015-certified traceability protocols.
Our Factory:
Our advanced manufacturing facility is engineered for precision and efficiency, seamlessly integrating state-of-the-art technologies such as CNC machining, Mirror EDM, conventional EDM, and high-precision wire cutting to ensure exceptional mold accuracy and repeatability. With a robust production capacity supported by 15 rubber compression molding machines and 2 LSR injection molding units, we are well-equipped to handle high-volume, time-sensitive production demands.
Quality assurance is at the core of our operations. We employ sophisticated inspection equipment—including 3D projectors, sealing integrity testers, durometers, and elasticity gauges—operated by a highly skilled quality control team. As an ISO 9001 and IATF 16949 certified facility, we adhere to the highest international standards for quality, reliability, and process control.
To optimize production consistency and operational efficiency, we utilize a suite of automated systems, including AutoDryers, high-speed doming machines, and precision die-cutting equipment. This integrated approach enables us to deliver high-performance, precision-engineered components that are fully customized to meet the most rigorous industry requirements.
