End-to-End Manufacturing Process

We manage the entire lifecycle of aluminium casting in-house, ensuring total control over quality and lead times. By integrating traditional casting techniques with modern technology, we provide a true one-stop solution that takes your project from a digital design to a finished, market-ready component.

From Wax Pattern to Shell Building

Our process begins with precision. For investment casting, we inject wax into metal dies to create exact replicas of your final part. These wax patterns are assembled onto a tree and dipped into a ceramic slurry. We repeat this coating process to build a robust ceramic shell capable of withstanding high temperatures. This automated shell-building phase ensures uniform thickness and structural integrity for the pouring stage.

Pouring, Shell Removal, and Heat Treatment

Once the shell is dry, we melt out the wax—hence the term “lost wax”—and fire the ceramic mold. We then pour molten aluminum alloys into the hot shell, filling every intricate detail. After cooling, the ceramic shell is vibrated or blasted off to reveal the raw aluminum investment casting. To enhance mechanical properties like strength and hardness, we perform standard heat treatments (such as T6) tailored to the specific alloy used.

CNC Machining and Surface Finishing

A raw cast often needs refinement to meet tight tolerances. Our facility is equipped with advanced CNC turning and milling centers to handle critical dimensions. Whether it involves facing, boring, or tapping threads properly, we ensure every feature mates perfectly with your assembly. Finally, we apply surface treatments like powder coating, anodizing, or shot blasting to improve corrosion resistance and aesthetics.

Rapid Prototyping and 3D Printing Integration

Speed is essential in product development. Before committing to hard tooling, we offer rapid prototyping services. We utilize 3D printing to create initial wax patterns or prototype parts, allowing for quick design validation. This includes mastering 3D printing threads to ensure fit and function are verified early, saving you time and money on production molds.
