First, how to speed up the product molding cycle? Optimizing the mold structure design and cooling system is the key. Of course, a good injection molding machine with high stability is also necessary.

Second, reasonable selection of high-precision mold processing equipment, project follow-up team, and QC department to implement the entire project, which will directly lead the customer to spend less time modifying and adjusting the mold later. And a reasonable selection of processing technology will shorten the processing time of the entire bottle cap mold.

Third, a good mold must have a long working life under high-speed operation. To achieve this, it is necessary to use high-quality bottle cap mold materials and parts. It also keeps the structure of the bottle cap mold simple and easy for customers to maintain in their own factories.

Fourth, the compatibility with the bottleneck. Under normal circumstances, if the above requirements are implemented, then the assembly is no problem.

How to prevent deformation in the bottle cap mold?

On the premise of ensuring the hardness of the bottle cap mold, pre-cooling, hierarchical cooling quenching or warm quenching process shall be adopted as far as possible.

2. Changping heat treatment advocates. For fine and messy molds, when the conditions permit, the nitriding heat treatment plant advocates the use of vacuum heating quenching and cryogenic treatment after quenching as much as possible.

3. For some fine and messy molds, pre-heat treatment, aging heat treatment, and tempering and nitriding heat treatment can be used to control the accuracy of the mold.

4. When the nitriding heat treatment plant repairs bottle cap mold blisters, pores, wear and other defects, use cold welders and other correction equipment with low thermal influence to avoid deformation during the repair process.

5. The mold structure design should be reasonable, the thickness should not be too large, and the shape should be symmetrical. Experts said that the deformation law should be mastered for the larger deformed mold, and the processing allowance should be reserved. For large, fine and messy molds, a combined structure can be used.

6. ​​Fine and messy molds must be soft-nitrided in advance to eliminate the residual stress that occurs during machining.
