Dongguan injection mold with inadequate heat production in:

A, thermal expansion, thermal expansion and contraction should be considered when we design problems.

Two of the manufacturing cost, Dongguan injection mold increases, price system standard fittings hot pouring high effect, hot runner molds popularity.

Three, the thermal radiation is difficult to control, the heat loss of hot runner's biggest problem is the runner, is a major issue to be solved.

Four, the overall die shut height increase, for installation of hot runner plate, Dongguan overall height increased with the increase of injection mold
