The difference between coated mold and two-color mold

Plastic mold (secondary molding) : two kinds of plastic materials are not necessarily in the same injection molding machine injection molding, divided into two molding; After the product is removed from a set of molds, it is put into another set of molds for a second injection molding. In the design of the adhesive die, attention should be paid to the positioning of the hard adhesive parts, the adhesive parts should be sealed reliably, and there are reverse inclination holes on the adhesive parts to prevent the deformation of the glue.

Plastic injection mold needs to fully consider the size of plastic parts, plastic injection processing, mold accuracy, product positioning, operation, take and place, dimensional accuracy compared with the requirements of ordinary injection mold precision doubling. Although the accuracy requirements of the two-color injection mold are also very strict, the plastic injection mold is more complex than the two-color injection mold. The two-color injection molding is completed by the same injection molding machine, and the product has not been sufficiently cooled, and the size fluctuation of the molding is not obvious.


Application of plastic cladding injection molding process

Appearance products, conductive products, power outage terminals, hardware handles, product strengthening, waterproof products, electrical products, beauty products, maternal and child products, small household appliances, electric fans, new energy vehicles, game consoles, sports equipment, small night lights, table lamps and other applications are very wide.

Two-color mold: two kinds of plastic materials in the same injection molding machine injection, divided into two molding, but the product only one mold mold. Generally, this molding process is also called double injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine.


Two-color mold is increasingly popular in the market at present. This process can make the appearance of the product more beautiful, easy to change color without spraying, but the cost is expensive and the technical requirements are high. The front and back dies of the two-color mold must fit after rotating 180o in the center. This check action must be done at design time. It is best to design the water mouth of the three plate mold to automatically release the mold. Pay special attention to whether the release action of soft glue mouth is reliable.

Application of two - color injection mold process

Two-color injection molding has been widely used in electronic products, power tools, medical products, household appliances, toys and so on almost all plastic fields, two-color mold production and molding and two-color multi-color injection molding machine and two-color injection molding raw materials research and development has also been rapid development. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
