Dual-material injection molding is a technology that injects two different plastic materials into the mold at the same time and forms them. This technology can achieve diversified design of product appearance and function.
Dual-material injection molding completes two injection processes on the same machine by using two independent injection units. First, the first plastic is injected into one cavity of the mold, and then the second plastic is injected into the other cavity. The two plastics are fused together in the mold to form the final product.
Dual-material injection molding is widely used in the automotive industry, electronics industry and daily necessities manufacturing. In the automotive industry, it can be used to produce parts such as door handles; in the electronics industry, it can be used to produce electronic products such as mobile phone housings; in daily necessities manufacturing, it can be used to produce daily necessities such as toothbrush handles.
Dual-material injection molding has the following advantages:
- It can complete the injection molding of two different materials on the same machine, which improves production efficiency.
- Allows designers to freely choose different material combinations to achieve specific design requirements.
- Reduces assembly steps and reduces production costs.
- Improves product strength and durability.
Although the two-material injection molding process has many advantages, it also has some disadvantages:
- Requires special equipment and technicians to operate, which increases investment costs.
- For some complex-shaped products, it may be difficult to achieve a perfect combination effect.
