Metal Insert Plastic Injection Molding

Many plastic parts need threaded holes or conductive contacts. The old way is to mold the plastic first, then heat-insert brass nuts. This takes time and the nuts may fall out. Hayi Technology's metal insert plastic injection molding puts the metal part (brass post, nut, or conductive piece) into the mold before injection. The plastic wraps around it. The metal part can never be pulled out. For example, a smart meter client used to add 6 brass nuts after molding. They often missed some nuts. We changed to insert molding. One shot made the whole part. Assembly efficiency went up by 30%. This case shows insert molding does not add cost. It removes later trouble. Our MOQ is 1 piece. We can do the insert process even for samples.

Precise Positioning and No Flash are Our Strengths

Insert molding has two risks: the metal part gets pushed off position, or plastic flows into the threads. Our molds use a precise locating system. We keep metal part position error under 0.02mm. We apply our utility model patent "a foot pad molding die that is easy to demould" (ZL202123396798.0). This patent helps the mold release smoothly during insert molding and reduces flash. We hold ISO9001:2015 certification. Each batch gets a torque test and pull-out test to ensure the insert is strong. Before packing, we do 100% full inspection. We also accept third-party inspection. You can trust our metal insert plastic injection molding service for your clients who need strong, permanent metal features in plastic parts.

Agents worry that insert molding requires high MOQ. At Hayi Technology, our MOQ is 1 piece. Custom sample time is 1 day minimum. Send us your drawing. We check the insert spec and locating method. After order confirmation, standard lead time is about 15 days. Repeat orders are faster. Payment: 30% deposit for standard products, 50% deposit for custom products, balance before shipment. We support EXW, FOB, and DDP. During production, we send photo or video updates. If goods arrive damaged, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. We can also mix different colors or models in one order. You do not need to find two factories. We do it all for you.
