We make great tools for low-volume manufacturing，especially when quantity for hundreds and thousands of parts, we can use aluminum and Steel material to build the mold. To shorten lead-time and reduce cost, we share the mold base and different mold cavity. The material used will depend on the type of resin, characteristics of the parts and the number of parts you required.
Langwei has the equipment, the skill and the experience to help you create world-class rapid tooling for plastic injection molding and pressure die casting. Your rapid mold tools are made with high-quality P20, Nak80 or H13 tool steels. We use imported multi-axis CNC mills, grinders and EDM machines to create complex geometries with multiple surface finishes.
Langwei is a world-class provider of advanced plastic injection molding services. We offer a complete manufacturing solution that covers every aspect of raw material verification, tool making, part fabrication, finishing, and final inspection. Our professional team of manufacturing experts is committed to providing you with the highest level of professional support for plastic injection molding services of any size or complexity
Raw plastic pellets are first dried and, if necessary, mixed with coloring agents. Inside the machine the pellets are heated and mixed until the resin is semi-liquid. This liquid is then injected under high pressure through a nozzle and into the gate and runner system of the mold. Resin fills the cavity, forming the shape of the part. It’s then cooled, the part ejected, and the process begins again.
Depending on the complexity of the design and possible heat treatment, a plastic injection mold tool can be made in five days to two weeks.
Once a tool is made, plastic injection molding is the fastest and most cost-effective way of manufacturing hundreds of thousands of finished plastic parts. Molded parts have excellent surface finishes with reliable and repeatable dimensional tolerances. And there are resins available to suit most common applications.
The cost of a plastic injection mold tool can be a significant percentage of the total order for small volumes. However, this cost can be amortized over larger volumes so that it doesn’t become an issue. Rather, plastic resin and cycle times become the main cost drivers for larger volumes.
Our products have accumulated a plethora of accolades, from red dot prizes as well as the adoration of customers from across the globe.
