Thermoplastic foam molding is one of the widely used processes 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 foam molding.
When it comes to the Thermoplastic foam molding, 2 questions are usually asked:
Q. What are the PA, PS, POM, PE, PP, EP, ABS, PMMA, PC, and PVC plastic shrinkage?
A. When the material solidifies (crystalline Thermoplastics) from the amorphous state, the used polymers form a highly aligned and closely packed structure. This leads to a significant volume change manifested as high shrinkage.
Q. What kind of steel material is suitable for the 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 materials.
