Yuav ua li cas faib cov pwm raug theem

1. Moulds refer to precision forming tools used for batch forming, stamping and other products. The accuracy of the mold includes the accuracy of the parts obtained in processing and the production time guarantee
It can prove the quality awareness of product accuracy, but the mold accuracy usually refers to the accuracy of mold working parts.
①. The concept of precision in mold processing refers to the degree of conformity between the actual geometric parameters of the mold parts after processing and assembly and the design geometric parameters.
②. The concept of precision in mold production refers to a mode of thinking that is gradually formed by employees in production practice and guides their production behavior, a kind of quality awareness, yog, in the behavior of employees, always implement the quality of product accuracy awareness.
2. The content of mold accuracy includes four aspects: dimensional accuracy, shape accuracy, position accuracy, and surface accuracy. Since the pwm is divided into two parts, the upper mold and the lower mold, the mutual position accuracy between the upper mold and the lower mold is the most important among the four accuracy.
3. The accuracy of the mold serves the accuracy of the product. High-precision products must be guaranteed by a higher-precision mold. The accuracy of the mold must generally be higher than the accuracy of the part by 2 or more.
