One Stop Solution Manufacturer for all kind of Stamping Products and CNC lathed products.
Wenzhou flat washers, the details determine the result of the product + the fastening of the BMW-grade raw materials as solid as a rock
The hardware that manufactures Wenzhou flat washers says that the mold for flat washers, whether in the design and production, or the initial processing of the mold, including the actual production of the assembly, requires our careful care to ensure the stability of the flat washer mold. And the quality is qualified, Xiaoshuo will understand with you: 1. During operation, the extension of the punch into the female mold should be strictly controlled to avoid aggravation of wear. After the flat gasket mold is used for a period of time, the edges of the convex and concave molds will appear A wear groove mark, at this time, we can repair the mold in advance, which can reduce the friction, prevent the crack caused by the wear groove mark, and avoid the additional bending moment caused by the uneven gap between the concave mold and the convex after abrasion. At low temperatures in winter, preheat the flat washer mold before use to prevent the punch from being cold and brittle. 2. Contact surface In order to avoid premature wear of the flat washer mold due to uneven force, the surface must be kept clean and free of impurities, oxide scale and rust. If the surface roughness is deteriorated, we need to grind and polish it in time. 3. Increase lubrication during working hours. Phosphate treatment and lubrication should be used when extruding ferrous metals. In the cold extrusion process, the temperature of the flat gasket mold rises relatively quickly, so it is necessary to cool down regularly. Hardware, 15 years of focus on Wenzhou flat washers, 5,000 square meters production workshop, 3 million punching production capacity per day, imported and national standard raw materials, 16 quality inspection layers strictly controlled, hundreds of precision processing production equipment, flat washers production accuracy can be Up to 0.01mm. It can quickly solve the problem of customizing time for flat washers, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose to rest assured!
