Why choose plastic CNC machining?

Plastic CNC (Computer Numerical Control) consists of machining a plastic block in the mass. This method of digital milling by material removal, called “subtractive”, allows more rigorously identical copies of the same quality to be obtained for all copies of the same lot. Very close series parts, they can be used for visual and functional tests.

Advantages of plastic CNC machining

  • Wide range of resins in the “right material”: plastic CNC machining allows parts to be obtained with mechanical properties close to the injected part, depending on the desired functionalities and the desired final appearance. Thus, it is possible for example to obtain transparent parts and even to machine certain metals such as aluminum and brass.
  • Wide range of finishes: after machining, polishing is possible to remove rough edges. It is also possible to paint the prototypes in the color of your choice. You can find our finishes here.

    Anodizing finish

  • A high-performance method: this “subtractive” technique allows very high performance in terms of quality for even the most complex geometries.
  • Ideal for parts with larger sizes: the use of the “subtractive” method makes the creation of prototypes larger than 600 mm easier and more efficient than stereolithography and vacuum casting.
  • Economical and fast: due to the lack of mold, costs and times are reduced. This is the most efficient and fastest method of rapid prototyping for quantities of fewer than 10 parts, allowing greater responsiveness to your needs.

Limitations of plastic CNC machining

  • Few economies of scale: the limitation of this technique is that it does not allow significant economies of scale in the absence of mold.
  • Production of small quantities: due to very limited economies of scale, this method is not recommended beyond 10 prototypes or plastic models.

Preferred uses of CNC machining

For all the reasons mentioned above, plastic CNC machining is recommended for:

– production of units for visual and functional tests

– mechanical, aesthetic and thermal material validation

– shape tests (templates) and adjustment tests (fitting of parts)

– production of one to ten parts

– production of unit parts
