We are leading supplier of permanent magnets and magnetic assemblies in China and we provide service for one-stop magnets purchasing.
Define specifications (load, temperature, environment) and select ASTM/ISO-certified raw materials for optimal performance.
Engineer CNC-machined molds with ±0.05mm tolerance, validated via 3D simulation for accuracy.
Produce samples via compression/injection molding; test durability, elasticity, and chemical resistance.
Execute controlled mixing and curing (150–200°C) with real-time SPC monitoring for consistency.
Conduct dimensional checks, tensile tests, and leak-proof validation per ASTM/ISO standards.
Provide material certifications, RoHS/REACH compliance, and post-sale technical assistance.
1.Industrial Machinery
Deliver wear-resistant, high-temperature rubber components (e.g., gaskets, dampers) with precision-molded designs to withstand heavy loads, abrasion, and hydraulic/pneumatic system demands.
2.Automotive
Provide vibration isolators, engine mounts, and sealing systems using FKM/NBR materials, optimized for thermal stability (-40°C to +200°C) and compliance with ISO/TS 16949 standards.
3.Sealing Solutions
Engineer custom O-rings, lip seals, and gaskets with chemical-resistant EPDM or FFKM for extreme pressure, fluid compatibility, and long-term leak-proof performance.
4.Railway & Locomotive
Supply anti-vibration pads, door seals, and conductive rubber parts meeting EN 45545 fire safety norms, resistant to UV, ozone, and temperature fluctuations.
5.Marine & Shipbuilding
Produce corrosion-resistant dock fenders, marine-grade seals, and waterproof cable glands using neoprene/hypalon, validated for saltwater exposure and MIL-SPEC durability.
6.Electronics
Develop EMI shielding gaskets, silicone keypads, and ESD-safe components with UL 94 V-0 flammability ratings and precise conductivity/resistance control.
We recommend FKM (Viton®) or silicone rubber for temperatures up to +250°C, offering superior heat resistance and durability for seals, gaskets, and O-rings.
Yes! Our CNC-machined molds and ISO 9001-certified processes ensure precision (±0.05mm) for components like vibration mounts and hydraulic seals.
Typically 2–4 weeks for prototype molds, leveraging CAD/3D simulations to expedite production of O-rings, grommets, or custom extrusions.
Yes. Neoprene or hypalon-based dock fenders and seals undergo accelerated weathering tests (ASTM G154) for marine durability.
We use EPDM or NBR compounds tested for chemical resistance (ASTM D471), ideal for gaskets, diaphragms, and tank linings exposed to oils, acids, or solvents.
Absolutely. Our chloroprene (CR) or fluorocarbon materials meet EN 45545 fire safety standards for cable insulation and anti-vibration pads.
Our platinum-cured silicone parts comply with FDA, USP Class VI, and ISO 10993 for seals, tubing, and diaphragms in medical devices.
We develop conductive silicone or carbon-black compounds with resistivity <10^4 Ω·cm for EMI shielding gaskets and static-dissipative pads.
