Services
Plastic Injection Mould Tools
We design and produce high-precision plastic injection moulds tailored to client specifications. Our tools ensure consistent quality for complex components across industries like automotive and medical. Advanced CNC machining and expert craftsmanship guarantee durability and performance.
CNC Machining
Our CNC machining services include 2D and 3D milling, turning, and grinding for tight-tolerance parts. Using Bridgeport VMCs and Heidenhain controls, we handle small batches or one-off components. This ensures accuracy for aerospace and defence applications.
Spark Erosion
Specialist spark erosion techniques create intricate shapes in hard metals without tool pressure. We use Hurco and ONA equipment for precision tooling in rubber and plastic moulds. This method suits complex geometries for medical and industrial sectors.
Prototyping
We offer rapid prototyping to validate designs before full production. Using CAD/CAM software and CNC machines, prototypes are produced swiftly for testing. This reduces time-to-market for sectors like electronics and pharmaceuticals.
Refurbishments
Our refurbishment services restore worn or damaged tools to original specifications. Techniques include welding, grinding, and re-machining. This extends tool life for clients in automotive and construction industries, ensuring cost-effective operations.
