Double pattern injection molding principle, where is it suitable for use

1. The former is injection molded on a two-color machine, which can be molded at one time, and can have two color effects and different material composition; The latter is completed with an ordinary injection molding machine. Now take out the one-time molding product and put it into another injection molding machine for re molding.

2. The former has two sets of molds, and the rear mold is the same and interchangeable; The latter is not required.

Difference between two-color injection molding and secondary injection molding

Principle of double pattern injection molding

It has two material barrels 1 and 5, and its nozzle structure is somewhat special. In addition to the function of normal nozzle, it can also be driven to rotate by the gear 3 installed at the rear. During molding, the melting materials of different colors are plasticized in the barrel 1 and 5 respectively, and the gear 3 drives the rotation shaft 4 to rotate, so that the melting materials of different colors enter the mold cavity alternately, so as to obtain plastic products with different colors and patterns radiating from the center to the surrounding.
