Description

technical field [0001] The invention relates to a temperature control device for rapid heating and cooling of plastic moulds, in particular to an injection molding process requiring high-precision and high-gloss products, and belongs to the technical field of plastic injection molding. Background technique [0002] As one of the important molding methods in plastic processing, injection molding is widely used in various fields of industrial production. With the increasingly wide application of plastic products, enterprises have higher and higher requirements for the precision, surface quality and strength of plastic products. Higher requirements have been imposed, and the traditional injection molding process has been difficult to meet this requirement. At present, the surface quality and surface strength of plastic products are mainly improved by plastic spraying technology. On the one hand, the surface quality of injection molding products has a great influence on the qu...
