Can Plastic Water Cups With The Same Cup Shape But Different Materials Use The Same Set Of Molds?

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, structural characteristics of the product itself, etc. If If the above conditions can be met, for example, the blowing mold of AS and PC material can use a common set of molds, and the plastic mold of PC can share a set of molds with 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 process of AS and Tritan is obviously different, and the production parameters are also quite different.

Secondly, there are still more situations where the same set of molds cannot be shared. Take a simple disposable coffee cup as an example, which are also injection molds, but if the material is melamine and Tritan, it 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 thoughts very well. After all, the cost of plastic molds is relatively high, and I hope that as many compatible uses as possible, so friends must consider which material to use when deciding on plastic products. , of course, the premise is a reasonable pre-order of cost performance and cost input.

Similarly, due to the softness of the plastic material PP, there will be material changes such as shrinkage during production, so it cannot share molds with other plastic materials.

The requirements of the production process do not entirely depend on the material, but also on the product structure and the quality of the finished product. The relative production cost of high material price must be high, but it does not mean that the production time is longer or the production labor cost is high, but the material cost is high.
