Precision Machining Plastic Prototype and Production Machined Parts

Plastic CNC Machining Service

3D printing processes such as FDM, SLA and SLS are today considered the most economic way to make plastic prototypes. Sometimes, however, certain non-printable materials are needed, and sometimes CNC machining is the only option. Our company has rich experience making plastic concept models and precise functional components. Understanding the properties of different plastics, with lots of testing and experimentation with pre-heating, tool paths and other factors, we are able to minimize deformation on plastics such as PP, PA (nylon), PE, POM (Delrin), etc. 3Q Machining provides a range of solutions for the machining of plastic parts.

Advantages of our Plastic CNC Machining


One of the main advantages of plastic machining — especially for prototypes and short-run production — is its ability to create parts without molds or support structures. The most expensive part of injection molding is creating the metal tooling; with CNC machining, however, that stage is not required.


Because machined plastic parts are made directly from a plastic sheet or rod using a digital file, it is easy for engineers to make small modifications to the digital design between iterations. And since they do not have to make new tooling, there is little cost involved in upgrading and updating the part.


The range of machine tools allows for total control over a part’s final appearance, offering fine trimming and cutting capabilities not available to injection molding or 3D printing equipment. Machined parts are also free from 3D printer layer lines and seams from injection molding parting lines, which can be unsightly to view.
