Further, if the mold is installed in a molding machine with a 300 tf capacity, even if the molding operation is possible, since usually the hourly cost of a 300 tf machine is higher than that of a 100 tf machine, the molding operation becomes high in cost. The required mold clamping force of a mold can be calculated using the following equation.
The thermoplastics TPU and TPC, for example, form a strong chemical bond with ABS, polycarbonate, and PBT Valox (a type of polybutylene). Santoprene TPV, a tough but flexible “vulcanizate” widely used in weatherseal, food service, and wire and cable applications, is more restrictive, readily bonding to polypropylene but little else.
