Two-Color Injection Molds for Toothbrushes

These two-color injection-molded toothbrushes feature an integrated design combining rigid materials (such as PP or PMMA) with soft materials (such as TPE or TPU), eliminating the need for secondary assembly and ensuring a secure, seamless bond. Made from food-grade materials that meet safety standards for oral contact, the soft components can be designed with anti-slip textures or flexible necks to enhance grip comfort and provide a shock-absorbing brushing experience. A key highlight is the ability to create distinctive visual effects—such as combinations of transparent and colored, or matte and glossy finishes—while the single-step molding process reduces production and assembly costs. They are widely used in products ranging from adult manual toothbrushes and fun toothbrushes for children to electric toothbrush heads and interdental brush handles.
