the point of view of material production process, pvc is an amorphous material, which has some shortcomings in itself, so additives such as stabilizers, lubricants, auxiliary processing agents are added in the actual production. Only these steps can be achieved after injection molding, so we need to see if the ingredients are reasonable if there is a problem with the batch of our products. Then we will talk about how to troubleshoot material problems.
