Production of Two-Color Toothbrush Mold (PP+TPE Material)

The two color toothbrush mold is produced using a rotating shaft  design within the injection mold structure.

This mold is used on angle injection molding machines, requiring precise alignment and rotation.

The toothbrush is made from PP and TPE.

PP provides rigidity and durability, while TPE adds a soft, comfortable grip for the user.

The core and cavity are used from high-quality 1.2316 steel, offering excellent corrosion resistance and polishability.

Although the structural design is more challenging, attention to detail ensures optimal performance.

The runner system often employs a full hot runner with multiple valve gates

to ensure precise material distribution and improve surface finish.

Proper venting and cooling designs are essential to prevent defects and ensure consistent cycle times.

At YUEYI Mould, we focus on translating customer needs into optimal production solutions.

Every new mold we design undergoes rigorous trial molding and inspection to guarantee quality and functionality.
