Due to the requirements for micro precision, enterprises must have the capability to produce high-quality products, featuring highly automated and comprehensive precision testing, destructive rubber testing, mechanical seal testing, pressure testing, a complete quality control system, and fully equipped production inspection facilities. The precision must exceed that of ordinary inspections by an additional decimal point. Production equipment must include vulcanization molding machines with pressures of 500-600 tons or higher. The precision of rubber products produced by small enterprises generally cannot meet these standards.
For example, requirements include dimensional accuracy, rubber product quality, tensile performance, and compliance with physical and chemical parameters.
