Custom Overmolding With Tiandiao

Need overmolded parts that are truly custom? You have come to the right place. Tiandiao delivers high-quality, on-demand injection molding for prototypes and production parts. 3D printing service

Simply put, overmoldinglets you combine multiple materials into one part. One material, usually a thermoplastic elastomer (TPE/TPV), is molded onto a second material, which is often a rigid plastic. Think about your toothbrush handle where the single piece has both rigid and rubbery components. It’s a great way to make plastic parts perform and look better.

Tiandiao takes a “have it your way” approach to all types of injection molding, no matter your level of experience. We specialize in complex projects, including those requiring side action or hand loaded inserts. Our goal is to provide a long-term overmolding solution, moving beyond rapid prototyping, with dedicated project managers and engineering experts to communicate through all project stages from design to production. We offer molding solutions for every industry, including medical injection molding. Insert Molding service

Overmolding Design Tips

Overmolding Design Tips • Wall thicknesses between 0.060" to 0.120" (1.5 mm-3 mm) generally provide the best bonding.
• Keeping radii between 0.020" or 0.5mm minimum in corners reduces localized stresses.
• If the part requires the use of thick TPE sections, they should be cored out to minimize shrinkage problems, reduce the part weight and lower cycle time.
• Avoid deep or un-ventable blind pockets or ribs in your design.
• Use gradual transitions between wall thickness to reduce or avoid problems with flow (back fills, gas traps, etc.)
• The TPE/TPV should be less thick than the substrate to prevent warpage, especially if the part is flat, long, or both.
• Overmolding needs mechanical or chemical bonding to the substrate, so your material choices should enable this.
