Services
CNC Milling
Our 3, 4, and 5-axis CNC milling services produce complex aluminium components with tight tolerances. Using advanced machining centres and FeatureCAM programming, we handle batch sizes from 10 to 10,000 units. Automation cells ensure consistent quality and efficient production for industries requiring precision-engineered parts.
Aluminium Anodising
We coordinate electrochemical anodising processes that enhance aluminium durability and aesthetics. This creates corrosion-resistant surfaces with colour options, ideal for visible components in demanding environments. Partnering with specialist finishers ensures adherence to industry standards for quality and longevity.
Powder Coating
Electrostatic powder coating application followed by thermal curing provides durable, wear-resistant finishes. Suitable for both functional and decorative requirements, this process offers various textures and colours while meeting industrial performance standards for longevity and environmental resistance.
Wet Painting
High-quality wet paint application using spray methods delivers precise finishes for visible components. Available in gloss, matte, and textured options, including rubberised or suede effects, ensuring aesthetic appeal and protection for high-end audio equipment and architectural lighting components.
Laser Marking
Permanent laser marking creates barcodes, serial numbers, and regulatory symbols without surface damage. Using low-power beams maintains material integrity while providing tamper-resistant identification for traceability in military, automotive, and industrial applications.
