Plastic Injection Mould gate types
1.Pin Point Gate
Feature:A small diameter round gate, usually used in place of direct gate as the gate residue on part is not obvious
2.Direct Gate
Feature:Injection directly by main runner
Advantage:Precise size, good quality, good filling, small pressure loss, mould no need to process runner
3.Edge Gate
Feature:The most general type of gate, Injection by side or edge, gate shape regular rectangular, especially rectangular gate
4.Sub Gate
Feature:A round or spot gate feeding the mold above or below the parting line
5.Hot runner
Feature:Replace cold runner to simplify mold structure, short mold development and manufacturing cycle, and improve product quality
