Plastics play a fundamental role not only in everyday life, but also in highly specialised fields. As well as being found in common objects such as bottles and packaging, they stand out for technical properties that make them indispensable in industry. Corrosion resistance, durability and tolerance of high temperatures are some of the properties that make them ideal for technical applications.
CNC machining is the most advanced method for turning these materials into high-precision technical components. It allows custom parts with complex geometries and minimal tolerances to be produced with flawless results. Every detail is handled with extreme precision, eliminating dimensional or form errors and ensuring perfect repeatability from one part to the next.
The engineering plastics most commonly machined on CNC include Delrin, known for its outstanding mechanical and thermal resistance, and Ertacetal, valued for its dimensional stability and wear resistance. Other plastics that can be machined with CNC technology include:
- 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.
Components in engineering plastics and composites
CNC machining of engineering plastics is particularly advantageous for companies that need high-quality custom components. This approach meets specific needs, from prototypes to one-off parts or small batches. CNC technology also optimises the production process, reducing machining times and ensuring consistent quality.
The sectors that benefit most include mechanical engineering, where engineering plastics are used for gears, valves and turbines, and the medical sector, which uses them for surgical devices and laboratory instruments. Electronics and aerospace also have key applications, thanks to the ability to produce precise, durable components for high-tech devices and aerodynamic structures.
Choosing a specialised turning shop means choosing a partner that combines advanced technical skills with state-of-the-art technology. CNC machining of engineering plastics not only meets the need for precision and reliability, but is a versatile and competitive solution for an ever-changing market.
