open nozzle


open nozzle

open nozzle include pin point gate and direct gate.The open nozzle also can divide into two parts.The one is drop gate ,the other one is adiabatic bin in nozzle.

direct gate hot runner
To the direct gate of open nozzle
This kind of nozzle can keep the high temperature and prevent from freezing.The direct gate with smaller pressure drop should be well deliver the hold pressure .Besides,it can be used in injecting large-scale,long process,thickened wall and deep cavity components.The direct gate of open nozzle is suitable for replacement of heat-sensitive plastic and colouring plastic .Because this style of nozzle is easy to clean that we recommend to process the secondary use of plasic material.

To the pin point gate of open nozzle
The gap of heat insulation is made up of nozzle and the hole in manifold.Pin point gate will decrease the wire drawing and flash.It apply to amorphous plastic and the plastic of slower crystallization such as PP,PE and thermoplastic elastomer.You'd better not select the pin point gate of open nozzle to inject the material of heat insulation and the plastic material which need change the colour.

These information od open nozzle i told stop here.I hope it will help you!
