Recently, the website of the Science and Technology Department of the Ministry of Industry and Information Technology of the People's Republic of China issued Notice No. 3 of 2016, approving the publication of 643 industry standards such as reciprocating vacuum pumps. Among them, 20 new standards for the industry, such as "Part 1 of the motor iron core injection die: overlapping riveting and convex die", were formulated and completed by the mold standard committee in 2014.

The 20 standards of the mold industry issued in this batch are all new standards that the industry urgently needs to fill the gaps in the country and will provide important technical support for the development of the mold industry.
