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 in one go and can have two color effects

and different material compositions; The latter is completed using a regular injection molding machine. Now, the molded

product is taken out and placed on another injection molding machine for further molding.

     2. The former has two sets of molds, the rear mold is the same and interchangeable; The latter has no requirements.

     The difference between two-color injection molding and secondary injection molding

     Principle of Double Pattern Injection Molding

     It has two material cylinders 1 and 5, and its nozzle structure is somewhat special. In addition to the usual functions of a

nozzle, it can also be driven to rotate by a gear 3 installed at the rear. During molding, different colored molten materials are

plasticized in barrels 1 and 5, respectively. Gear 3 drives the rotating shaft 4 to rotate, causing the molten materials of different

colors to alternately enter the mold cavity, thereby obtaining plastic products with different colors and patterns radiating from

the center to the periphery.
