The design principle of distributary channel

Distributary channel primary on the molten material into the mold flow and steering function, multi-cavity mould must set the distributary channel, if it is a single cavity forming large plastic parts, such as multi gate feed, also need to set up distribution.
the design principle of shunt way:
1. The melt should be in the shortest path, the minimum heat and pressure losses quickly into the cavity.
2. Melt from the gate into the cavity of the temperature and pressure should be the same, to ensure that the products of shrinkage cavity in the same.
3. Shunt way of turning point should with circular arc transition and the connection locations at the gate should be processed into bevel, and to facilitate the flow of the molten material.
4. In the injection pressure, ensure enough distributary channel cross section and should try to get the minimum length.
