Product Overview
Complex Parts Injection Molding is designed for plastic components with complicated structures, including undercuts, deep cavities, thin walls, and multiple integrated features. Customized molds are developed with advanced mechanisms such as sliders, lifters, and composite ejection systems to solve challenges including difficult demolding, incomplete filling, and deformation.
The cooling channels are arranged in separated zones to achieve balanced temperature control and reduce internal stress during molding. The solution supports various modified engineering plastics, ensuring complete parts with stable dimensions and reliable assembly performance.
These customized molding solutions are widely used for precision electronic housings, medical components with complex structures, automotive interior parts, and smart device housings.
Based on 3D drawings, physical samples, or product requirements, we provide complete mold development and injection production services, supporting prototype testing, medium-volume production, and long-term manufacturing.
