There are several ways to test the stamping parts

  The stamping parts of Dalian have high dimensional accuracy, uniform size of the same module, good interchangeability, and can meet the general assembly and use requirements without further machining. The design of stamping parts must be conducive to improve the utilization of metal materials, reducing materials, varieties and specifications, reduce material consumption as much as possible, using cheap materials in the circumstances allow, as far as possible to make parts less waste and do not waste blanking. The stamping die punch and die edge wear should be stopped in time, timely grinding, otherwise it will rapidly expand the mold edge wear degree, accelerate the mold wear, reduce the quality and die life. In order to guarantee the service life of the stretch stamping parts, the spring of the mould should be replaced regularly to prevent the fatigue damage of the spring.

  Practice has proved that the stamping process is directly related to the degree of difficulty in processing the parts, the quality of the product quality and labor efficiency, economic efficiency. In stamping production, metal stamping parts of the process occupies a very important position. Therefore, in the design of stamping parts, should be based on product technology, follow the following design principles. The design of stamping parts not only to meet the performance of parts, but also should have good process performance, in order to reduce the consumption of materials, prolong the life of the mold, improve productivity,

reduce costs and ensure the quality of stamping parts. In the actual production, it is often used in the process of the stamping process similar to the test, such as the deep drawing performance test, bulging performance test and other test materials to ensure the quality of the product and high pass rate.
