Versatile 2K Mold Durable Double Shot Molding For Toothbrush Handle

The toothbrush handle is a crucial component of the toothbrush. The 2K injection molding process combines hard plastic and soft rubber in a single molding process, ensuring the handle's strength while providing a soft, comfortable grip and increased anti-slip properties. The two-color process also gives the handle a more aesthetically pleasing design.

1. Mold Design: Determine the support and grip areas of the toothbrush handle
2. Mold Flow Analysis: Optimize the bond strength between the hard and soft plastics
3. CNC Machining and EDM Finishing
4. Mold Assembly: Install the rotary or slide system
5. Trial Mold Adjustment: Test comfort and bond strength

• Hard plastic section is durable and strong
• Soft plastic section is non-slip and comfortable
• Diverse appearances, supporting multiple color combinations
• Long mold life, suitable for long-term mass production
