First of all, plastic materials with similar material properties and the same production method can share a set of molds, but these are based on the establishment of many conditions, such as product process requirements, production difficulty, product structure characteristics, etc. If If all of the above conditions are met, for example, the AS blowing mold and the PC material can use a common set of molds, and the PC plastic mold can share a set of molds with the Tritan material, but it must not be because AS can be shared with PC, PC can be used with Tritan Sharing means that the materials of AS and Tritan can share a set of molds. The production processes of AS and tritan are obviously different, and the production parameters are also quite different. Secondly, there are more cases where the same set of molds cannot be shared. Take a simple disposable coffee cup as an example. They are also injection molds, but if the materials are melamine and Tritan, they must not share a set of molds. , because the two materials have completely different requirements on the production process, including the temperature, pressure, and production time required for production. Whether it is an injection mold or a bottle blowing mold, the editor understands the buyer's friend's idea very well. After all, the cost of plastic mold is relatively high, and I hope to use as much compatibility as possible, so friends must consider in advance which material to use when determining plastic products. , of course, the premise is reasonable pre-order and cost input. Similarly, because the plastic material PP is soft, there will be material changes such as shrinkage during production, so it cannot share the mold with other plastic materials.
