Plastics are among the most widely used materials in everyday life, found in common objects such as bottles, containers, packaging and much more. But they also have many technical and industrial applications, where they are particularly useful for their resistance to corrosion, fatigue and high temperatures. This is where CNC machining of technical parts in engineering plastics comes in: an effective, precise production process that delivers high-performance custom parts.
With CNC technology, plastics can be machined with extreme precision, producing perfectly shaped parts without dimensional or form errors. The process also allows complete control over machining, ensuring perfect repeatability from one part to the next.
So which plastics can be machined with CNC technology? The most common are:
- Delrin: a plastic known for its mechanical and thermal resistance, ideal for engineering and mechanical applications.
- Ertacetal / POM C: a polyacetal offering high machining performance and resistance to deformation and wear.
- PVC: one of the most common plastics, used in construction and in the production of pipes, profiles and fittings.
- Nylon: a very strong thermoplastic used in industry for gears, bearings, seals and many other applications.
- Teflon: a chemically inert material with excellent non-stick and antistatic properties, ideal for food and medical applications.
- Polyethylene: a plastic with excellent insulating properties, used for bottles, films, bags and many other applications.
To machine these plastics with maximum efficiency and precision, technologies dedicated to plastics are needed, such as specific cutting tools and the latest CNC machines.
CNC machining of engineering plastics: advantages and applications
CNC machining of technical parts in engineering plastics offers many production and quality advantages:
