Description

Technical Field

[0001] The utility model relates to the technical field of multi-cavity mold heating devices, in particular to a multi-cavity mold heating device with high efficiency and energy saving. Background Art

[0002] Injection molding is a method of producing industrial products, mainly used to manufacture various plastic products. During the injection molding process, the mold needs to be preheated so that the plastic can cool and solidify quickly before being injected into the mold. The preheating temperature is usually adjusted according to the type of plastic and the injection molding process.

In view of this, we propose a multi-cavity mold heating device with high efficiency and energy saving. Utility Model Content
