The mould industry is the base of the whole national industry .Manychina injection mould innovator are dedicated in injection mould design.There are many important systems in injection mould china,including running gate system,venting system,cooling system,ejecting system,constant temperature system,moulding system.

Running gate system

The feeding channel between the injection nozzle and cavity ,including main runner , branch runner ,gate and sprue well.
Venting system

In order to release the air and the gas from the plastic melt during the injection molding process, the venting system should be set up,usually Vents on the parting surface and fitting tolerance of push bar and insert.

Constant temperature system

It has direct impact on the quality of plastic parts and production efficiency.The mould temperature is depended on the type of the plastic raw material and the quality of plastic parts .

Cooling system

In order to improve the efficiency of the cooling system and the cavity surface's temperature uniform distribution ,cooling system should be designed as follows :

The layout of cooling system should be considered earlier than the demould mechanism.

Ensure the center distance of the cooling pipe and the distance between cooling pipe and cavity wall.

Lower the temperature difference of water in and out .
Strengthen the cooling efficiency upon the gate.
Cooling channels shouldn't be set on the weld line.
Ejecting system

The mechanism which pull the plastic part and the running system out of the injection mould is called demould mechanism or eject mechanism.
