Hot runner system brand:
Mould Precision Co., Ltd. use hot runner for mould making with custom require. We offer high quality hot runner mould making. We are experienced in building a variety of hot runner moulds like as follow brand :
MOLD MASTER, HUSKY, HASCO, DME, YUDO, INCOE, THERMOPLAY, SYNVENTIVE
Hot runner advatage:
Hot runners are popular in high production parts , especially with a lot of cavities and the advantages of hot runner moulds are obvious :
- lower injection pressures
- lower clamping pressure
- no runners to disconnect from the moulded parts
- shot size is reduced by runner weight
- nozzle freeze and sprue sticking issues eliminated
- cleaner moulding process ( no regrinding necessary )
- having no runners reduces the possibility of contamination
- consistent heat at processing temperature within the cavity
- no runners to remove or regrind , thus no need for process / robotics to remove them
- cooling time is actually shorter ( as there is no need for thicker , longer-cycle runners )
Hot runner disadvatage:
However hot runner also have some disadvantages , the cost is more expensive than a cold runner , it requires costly maintenance , and requires more skill to operate . Color changes with hot runner moulds can be difficult since it¡¯s virtually impossible to remove all of the plastic from an internal runner system.
Mould Design
Mould design is including DFM, Mould Flow Analysis, 2D Mould Layout and 3D Mould Drawing. It is part lay out, part line making, gate design, runner design, gating way, ejection method, cooling layout, etc.
Mould Making
Mould making is based on mould design and purchase mould base, steel and component by machined by CNC, EDM, Lathe, Gun Drill and Milling etc., make mould fitting and mould trial in the end. To see the idea into real by mass production.
