Excuse me, what are the current effective national standards and the acceptance standards of molds in the machining industry?

1. There is no special and formal industry standard in China.

2. Under the old system, there was a "ministerial standard" issued by the Ministry of Machinery Industry-JB, which was equivalent to the industry standard, and now it is rare.

3. The ministerial standards and industry standards are recommended, not mandatory, and are not binding on any enterprise.

4. I haven't seen the standard of mould acceptance.

5. Before signing the contract, the user can ask the supplier to carry out manufacturing and acceptance according to certain standards, but can't ask for acceptance according to certain standards afterwards.

6. Non-customized molds generally only accept function and final accuracy.

7. Special and customized molds can require the material, process, precision and integrity of each part, and confirm the design and even manufacturing process in writing.

8. If the customer has no requirements, it shall be implemented according to the standards of the supplier's factory, and the right of interpretation lies with the manufacturer. Factory standards determine the position of enterprises in the industry. Of course, it also determines the price.

9. High-value products can be inspected by a third party, and the third party will formulate special acceptance standards, such as the ship regulations formulated by the classification society. But not in the mold industry.
