Thermoplastic injection molding is one of the widely used process to manufacture plastic parts. Thermoplastics are basically polymers that can be heated to melt, and efficiently cooled to solidify to form the parts. No chemical change takes place during the molding process of thermoset materials.
Shanghai iMolding produces high quality, fast way, and repeatable plastic products efficiently and cost effectively using the process of China Thermoplastic Injection Moldmaking.
When it comes to the Thermoplastic injection moldmaking, 2 questions are usually asked:
Q. What are the PA, PS, POM, PE, PP, EP, ABS, PMMA, PC, PVC plastic shrinkage?
A. When the material solidifies (crystalline Thermoplastics) from the amorphous state, the used polymers form a highly aligned and a closely packed structure. This leads to a significant volume change manifested as high shrinkage.
Q. What kind of steel material suitable for above plastic core material (such as PA, POM with what steel material)?
A. Selection of mold steel completely depends on the customer requirements and cost considerations. There is no specific definition of what steel material should be used with those plastic core material.
