Thin flat washers manufacturers, how to distinguish between material selection and processing technology + 15 years of focus on flat washers

Manufacturers of thin flat washers, in threaded fasteners, the bearing surfaces of bolts, screws, and nuts cannot be made very large (limited by materials and processes), in order to reduce the compressive stress of the pressure-bearing surface and protect the connected parts The surface of the gasket is used. The following Xiaoshuo will take you to understand the material selection and processing technology of flat washers: 　　 Flat washer material selection: 　　 Flat washers should be made of hot-rolled steel plates, hot-rolled and pickled steel plates or cold-rolled steel plates, or used bar or tube cutting And rolling, forging and other processing methods to manufacture. The specific processing method is determined by the manufacturer's choice.　　 Flat washers without mechanical performance requirements are generally made of corner materials, such as Q235A. If the hardness is required but not high, thicker plates can be used to calender to achieve the required hardness. Spring washers and other anti-loosening washers are generally made of 65Mn70# or S50CM-S70CM, and they must be heat treated (quenched + tempered).　　 Flat washer processing technology: 　　 Flat washer processing technology has two main types, one is deburring treatment, the other is surface protection treatment; 　　 deburring treatment, the gasket should be polished, vibrated or other methods to remove burrs and flash. Hardware, 15 years of focus on thin flat washer manufacturer, 5000 square meters production workshop, hundreds of precision processing production equipment, 20000+ sets of precision stamping die customized production experience, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 passes The quality inspection is strictly controlled at all levels. It can quickly solve the urgent problem of flat washer time, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
