Two component 2K injection molding of hoothbrush handle

Two component 2K injection molding of hoothbrush handle

AnsixTech toothbrush handle two-color mold process and two-color injection molding process are a process method commonly used to manufacture toothbrush handles.

Double color mold process:

The two-color mold process uses a special mold to inject two different colors of plastic materials into the mold to form a two-color effect in one injection molding process. This process allows different parts of the handle to have different colors, thereby increasing the aesthetics and personalization of the product.

The main steps of the two-color mold process include:

Design mold: According to the design requirements of the product, design a mold suitable for two-color injection molding, including two injection molding chambers and a turntable or rotating mechanism.

Injection molding: Put two plastic particles of different colors into two injection molding chambers, and then melt the plastic through an injection molding machine and inject it into the mold. During the injection molding process, the mold rotates so that two colors of plastic are injected alternately, creating a two-color effect.

Cooling and solidification: After the plastic injection is completed, the mold will continue to rotate for a period of time to ensure that the plastic is fully cooled and solidified.

Take out the product: Finally, open the mold and take out the formed two-color toothbrush handle.

Two-color injection molding process:

The two-color injection molding process uses two different colors of plastic materials during the injection molding process. The two colors of plastic are alternately injected into the mold through an injection molding machine, thereby forming a two-color effect.

The main steps of the two-color injection molding process include:

Prepare plastic pellets: Prepare plastic pellets of two different colors separately.

Injection molding: Put two plastic particles of different colors into two hoppers of the injection molding machine, and then the plastic is melted by the injection molding machine and injected into the mold. During the injection molding process, the injection molding machine injects two colors of plastic alternately to create a two-color effect.
