Instant & Accurate Quotes
We don't use online automated quotation tools, because it is very inaccurate. Online quote platforms rely solely on calculations based on cutting amounts and fixed coefficients, they fail to account for actual processing nuances, such as material deformation after heat treatment, tight tolerance requirements, grinding after heat treatment, etc. Consequently, automated price calculations can lead to inaccuracies, ultimately increasing your costs.
But you can rest assured at DEK!
Our quotations are both cost-effective and accurate because we have a team of professional mechanical engineers who meticulously review each drawing. These engineers boast over 10 years of experience and possess deep expertise in programming, machine operation, post-processing, material properties, and more.

What is Plastic CNC Machining?
Plastic CNC machining is a manufacturing process where computer-controlled cutting tools shape plastic materials into precise components. You start with a solid block or sheet of plastic, and the CNC machine removes material layer by layer until your exact design is achieved.
This method works for many plastics, from flexible TPU to high-performance PEEK, and it allows you to create parts with tight tolerances and smooth finishes. You can use it for prototypes, small batches, or full-scale production. Because it’s computer-controlled, you get consistent, repeatable results with minimal errors.
What are the Advantages of Plastic CNC Machining?
Plastic CNC machining offers precision, flexibility, and consistent quality for any project.
- Excellent precision and tolerances
- Works for complex geometries
- Compatible with many plastics
