Injection Molding Mixing Screw Tip Assembly Manufacturer From China

We are proud to support our customers with full certification of all materials that we build their parts from. We want our customers to be assured of the quality in our parts. We even use the correct materials for the replacement parts. We understand the purpose of the part in the machine, so we know how to make a reliable replacement.

Here’s an example of how we help the customer: If you have a Nissei Molding machine and the OEM recommends CPM9V for your application, there are many materials that can be used. (As a customer, without Certification you would have no idea that a CPM9V unit wouldn’t last as long.) With complete Plastics, we offer full certification of the materials! You can rely on our expertise for your replacement parts.
