Is there a big difference between U casting and traditional injection molding?

Extremely wide. There are great differences between injection molding and casting molding. The main differences are as follows. ① Injection molding is physical molding and casting molding is chemical reaction molding. ② Injection molding exerts great pressure on the mold, generally above lOMPa. The pressure of casting molding on the mold is very small, generally below lMPa. Low pressure and low requirements for molds. So CPU can use fast and cheap resin mold. ③ Casting can flexibly change the formula and produce different products. ④ Casting molding is obviously lower than injection molding in raw material price, equipment price and manufacturing cost.
