CNC milling of plastics and composites

Service: CNC milling of plastics and composites.

CNC milling is a commonly used method of processing composites and plastics. It is performed with the help of an innovative CNC machining centre, which guarantees full precision of work and allows you to perform even the most complex tasks at a relatively low cost.

CNC milling of plastics and composites requires a specialist approach and appropriately selected processing parameters. At B52, we carry out projects from various materials, and each of these materials is characterised by different mechanical properties, which is why we use individually selected tools and milling strategies.

CNC machining of plastics also requires adjusting the temperature at which milling is performed to the specificity of a given material, which is determined, among others, by the type of polymer used. The optimal temperature is determined on the basis of the properties of the plastic used – the correct rotational speed ensures aesthetic processing and reduces the risk of overheating or even melting the material. For proper machining, you will need equipment with helical cutters for safe operation and an effective dust extraction system that can handle the large amount of chips produced. Providing appropriate conditions for milling plastics requires the experience of the person operating the machine.

With the help of our CNC milling machine, we process many types of plastics, including: PET / PET-G / PET-A (polyethylene terephthalate, polyester), PMMA (polymethyl methacrylate, acrylic, Plexiglas), PVC (polyvinyl chloride) solid and foamed, PC (polycarbonate) solid and chambered, PE (polyethylene), PP (polypropylene), ABS (acrylonitrile-butadiene-styrene terpolymer), PS (polystyrene), HPL (high pressure laminate, multilayer high pressure laminate based on resins), ACP (composite of aluminium and polyethylene, aluminium composite panel, Dibond). We also mill in materials supplied by the customer.

Thanks to advanced CNC machine and many years of experience, we provide smooth edges, high repeatability and accuracy even with complex geometry. We support both prototypes and production series. Finished elements can be additionally deburred, drilled or glued according to the customer’s specification.

Dibond is a composite material (ACP) consisting of a polyethylene core and aluminium linings. Aluminium can be powder coated, it can also be decorated with decor (e.g. brushing effect). May meet non-flammability standards. Due to the composite structure, dibond is a light and rigid material. CNC machining can involve cutting, creasing and engraving. Advertising and construction companies (in architecture) are the most common recipients of CNC dibond milling services.
