MASTER thin wall injection molding

Many master plastic rattan garden furniture mould effect of melt factors, summed up in 3 categories: the material factors, such as the type of plastic, viscosity; structural factors, such as type, plastic rattan garden furniture mold number and position of the gating system, the mold cavity shape and product thickness; elements of technology molding. Injection time here refers to the plastic melt filled cavity required time, do not include mold opening and closing, and other auxiliary time. Although the injection time is very short, the influence of molding cycle is also very small, but the injection time adjustment has a great effect on pressure control gate, sprue and cavity. Injection time reasonable help melt ideal filling, but also improve the surface quality of the products and has a very important significance to reduce the size tolerance.

MASTER thin wall injection molding injection time is much lower than the cooling time, about the cooling time of 1/10 ~ 1/15, this rule could be used to predict the plastic parts molding time for all. In mold flow analysis, only when the melt is completely by the screw rotating drive filled cavity case, injection timing for thin-wall injection molding in the injection time is equal to the set of process conditions. If there are filled in the cavity of the screw holding switch, then the results will be greater than the process conditions.
