Can the same set of plastic molds be used for processing different plastic materials?Is the processed effect the same?

The processing technology of plastic water cups is usually injection molding and blow molding.The blow molding process is also called the bottle blowing process.As there are many plastic materials used in the production of water cups, such as AS, PS, PP, PC, ABS, PPSU, TRITAN, etc., many manufacturers and water cup purchasers have come to think of it in order to control costs. Is it possible to process all plastic materials with the same mold?Is this possible? If the finished product can be processed, will the effect be the same?

So let's talk about it separately.In the injection molding process, the commonly used materials are AS, ABS, PP, and TRITAN.According to the characteristics of the material and the changes that occur during production, AS and ABS can be shared under the same mold, but PP and TRITAN cannot be used for injection molding, and they can also be shared with AS and ABS.

The shrinkage rate of these materials is different, especially PP material has a high shrinkage rate, coupled with the production method of the injection molding process, resulting in few plastic materials that can share molds.

In the blowing process, the production of AS and PC can share molds, and the performance of the products produced is also very similar.But for PPSU and TRITAN, the mold cannot be shared, because the two materials are very different.

PPSU is relatively soft for other materials, so once the same blowing mold is applied with AS material, it cannot be used for PPSU material.TRITAN material is relatively hard for other materials, and the same is true, and it is not suitable for molds that are suitable for blowing bottles of other materials.

However, in order to save costs, some water cup factories use AS, PC, and TRITAN to share blowing molds, but the products they make are really unsatisfactory. This editor will not make an evaluation.
