Casting is the plastic melt from the nozzle injection machine to the cavity of a group of feeding channel, is directly related to the forming quality and production efficiency of Dongguan injection mold.

It is the Dongguan injection mold a passage connecting the machine nozzle to shunt or cavity, can avoid both cohesion not intercept. Imported

In order to make the molten material to speed with the cavity in the mold, the shunt arrangement should be symmetrical and equidistant distribution. Therefore, Dongguan injection mold is adopting the runner trapezoidal or semicircular cross section, and the opening in the half mold with a stripper.

But for most Dongguan injection mold, to meet the needs of the premise should be reduced as much as possible to avoid increasing the cross-sectional area, the shunt block and extend the cooling time.
