manufacturer.
Basic requirements for Zhejiang manufacturing enterprises
One, design and development
1. Optimize the design of the suction and power of the solenoid coil of the micro valve, and simulate the electromagnetic force and the magnetic saturation of the magnetic material during the design and development process.
2. The durability life design index of the micro valve is not less than 50 million times.
2. Raw material parts
1. The heat resistance of coil enameled wire should not be lower than the requirement of 155 class (F) specified in GB/T 11021.
2. The valve body material should meet the requirements of RoHS Directive 2011/65/EU.
3. The magnetic performance parameters of the core material of the miniature valve should be: remanence Br≤0.5 T, coercivity Hc≤400 A/M, magnetic induction intensity Bm≥0.95 T.
3. Process and equipment
1. Use CAD design software to design various geometric sizes of shoe lasts or use shoe last scanners to scan shoe lasts provided by customers to generate shoe last processing drawings. The CNC last engraving machine performs automatic cutting according to the shoe last processing drawings. Make the entire surface area of the shoe last realize complete data processing and shaping.
2. In the process of shoe last processing, the tooling equipment should meet the tolerance requirements of 5.1.5 standard size.
Four, inspection and testing
1. The processing of key components such as the miniature valve moving iron core, static iron core, casing, etc. should be completed in one go with a centering CNC lathe, and the relevant surface roughness Ra≤0.4 after processing.
2. Special assembly equipment for miniature valve casing components should be equipped.
Five, quality commitment
1. It should be equipped with micro valve online detection system, insulation resistance tester, temperature measuring instrument, high-precision automatic multi-function digital multimeter, withstand voltage tester, inter-turn impulse withstand voltage tester, solenoid valve performance tester, solenoid valve dynamics Performance test bench, flow characteristic test system, durability test bench inspection and testing equipment.
2. It shall have the inspection capabilities of rated power, control performance, commutation action, switching time, flow characteristics, sealing, electrical performance, durability, pressure resistance, and appearance quality inspection items.
