The cost of CNC plastic machining depends on several key factors. Material choice plays a significant role, as some plastics, like PTFE (Teflon) or POM (Delrin), may be more expensive due to their specific properties. The complexity of the design also impacts cost, with intricate geometries or tight tolerances requiring more machining time and advanced tools. Production volume is another factor—while low-volume runs or prototypes may have higher per-unit costs, high-volume production can lower the cost per part due to economies of scale. Additionally, precision requirements influence costs, as tighter tolerances and specialized finishes require more detailed processes and quality checks. To get an accurate estimate, it’s best to request a quote with your project’s specifications, including material type, design complexity, and volume. This will provide a detailed cost breakdown tailored to your needs.
The ideal plastic for CNC machining depends largely on your application’s specific requirements, as different plastics offer distinct properties:
