◆ Shortcomings of hot runner system application
(1) The overall mold closing height increased, due to the addition of hot runner plate, the overall height of the mold increased.
(2) The heat radiation is difficult to control, the biggest problem of the hot runner is the heat loss of the runner, which is a major issue to be solved.
(3) There is thermal expansion, thermal expansion and cold contraction is a problem to be considered when we design.
