The source of qualified results for the production of refined flat washers needs to be controlled from materials [hardware]

Refined flat washers not only have precise requirements for size, but also have higher requirements for the coating and surface of the washer. To provide a qualified gasket requires the stamping plant to control the raw materials from the source. Xiaoshuo will take you to understand: 1. For the 100HV grade, ST12, ST13 and Q235, Q215, Q195 and other metal materials can be selected. 2. For 140HV grades, 08F, 08Al and 10, 10F materials can be selected. 3. For 200HV and 300HV grades, 45, 50, 60, 70 steel or 65Mn steel should be used. 4. At the same time, the stamping plant shall conduct material inspection, performance inspection, hardness inspection, salt spray inspection and appearance inspection of the raw materials before the raw materials are put into storage. It can be used after confirming that it is correct. Hardware, 15 years of craftsmanship focused on refined flat washers, 20000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality control . It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
