What is Custom Plastic Machining?
Custom plastic machining is the process of shaping, cutting, and fabricating plastic materials into finished components based on specific design requirements.
Unlike off-the-shelf parts, custom plastic machining allows you to produce components with precise dimensions, tight tolerances, and complex geometries suited to your application.
Through various machining techniques, material is carefully removed from a plastic workpiece to create highly accurate functional parts.
From lightweight structural parts, chemically resistant components, electrical insulators, or wear-resistant machine elements, custom plastic machining gives you the ability to produce high-quality parts designed for diverse, real-world industrial applications.

Laser cutting is a cost-effective solution for precision parts, complex shapes and detailed components. Choose from a range of materials including acrylic, polycarbonate, polyester and polyethylene.
CNC Turning
For cylindrical components requiring consistent precision, CNC turning provides exceptional dimensional accuracy and repeatability. It is ideal for producing complex shapes and round or tubular components with features such as threads, grooves, and internal bores. Perfect for applications requiring performance and reliability, CNC turning offers fast turnaround times, consistent results and smooth surface finishes.
Waterjet Cutting
Waterjet cutting is a versatile, eco-friendly solution for machining thick plastic sheets and complex shapes without introducing heat stress into the material. With no heat-affected zones, minimal waste, and rapid setup, it is ideal for intricate designs, clean cuts and maintaining material integrity across both thin and thick materials.
Heat Stamping
For high-volume production, stamping offers fast, efficient manufacturing with consistent repeatability. It is particularly effective for producing precision shapes, embossed features, and repeat components with minimal material waste and excellent production efficiency. Stamping is suitable for various plastic materials including ABS, polycarbonate, acrylic, and polystyrene. It also offers a wide range of colour and finish options,
Routing
Routing provides flexible cutting, shaping, and finishing for larger plastic sheets and fabricated components. It enables intricate detailing, smooth edge finishing, and efficient production of custom shapes across a broad range of engineering plastics. Choose from acrylic, polycarbonate, HDPE, PVC, and ABS for applications such as custom enclosures, bezels, panels, and promotional materials.
Milling
Milling is used to create complex three-dimensional features, contours, cavities, and precision-machined surfaces. For parts requiring intricate detailing and tight tolerances, milling delivers outstanding accuracy and finish quality across a wide variety of plastic materials. Ideal for custom housings, brackets, gears, and medical devices.
