Plastic Injection Molding Large Parts

Big outdoor trash cans, pallets, water tanks, and farm machine covers are too big for ordinary molding shops. Hayi Technology's plastic injection molding large parts service uses 1300 ton clamping force injection molding machines. We can also outsource larger tonnage if needed. We can mold parts up to 2 meters in length, width, and height combined. Part weight can reach 15 kg. For example, a logistics equipment company needed an anti-slip pallet with a load requirement of 1 ton. We used PP+GF30 material and added rib design. The actual load reached 1.2 tons. The client got a big order. This case shows large parts are a barrier for small shops, but they are an opportunity for us. Our MOQ is 1 piece.

Glass-Filled Materials and Hot Runner Molds

Large parts need high rigidity and stable dimensions. We often use PP+GF, PA+GF, and ABS. For equipment, we use large screw injection molding machines (screw diameter ≥70mm, max shot weight ≥2000g) and multi-point valve hot runners. This ensures fast and even melt filling. For molds, we use the ejection balance concept from our patent "a foot pad molding die that is easy to demould" (ZL202123396798.0). We add more ejector pins to prevent deformation. We hold ISO9001:2015 certification. We check flatness and warpage of each large part with special gauges. Before packing, we do 100% full inspection. We also accept third-party inspection. Our plastic injection molding large parts service can replace multiple welded metal parts with one plastic part.

A large plastic part can replace several stamped metal pieces that need welding. This reduces weight by 20-40% and lowers total cost. Our custom sample time is 1 day minimum for simple samples. Standard lead time is 15-30 days. 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 any problem occurs, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. You can bring us large part orders that other shops refuse. Our technicians can do mold flow analysis to predict warpage and optimize the design early.
