Amorphous material, low moisture absorption, poor fluidity, in order to improve fluidity, avoid bubble, plastic can be boring in advance, mold casting system should be thick and short, the gate section should be large, there must be no dead angle, the mold must be cooled, the surface is chrome-plated;
2. It is easy to differentiate. It is more easily differentiated from steel and copper at 200 °C. It will escape corrosion when it is differentiated, irritating gas, and the molding temperature is small;
3. When using the nozzle of the screw injection machine, the hole diameter should be large to prevent the dead angle from stagnation, and there is no insert. If there is an insert, it should be preheated.
