Aluminium and zinc die castings. From die design and build to inspection.
Aluminium and zinc die castings are best sourced from Rajkot, Pune, Chennai, Faridabad, Aligarh and Hosur. Indian die casters make housings, covers, brackets, heat sinks, handles and hardware in aluminium and Zamak, with machining and finishing.

[email protected]What is the difference between aluminium and zinc die casting?
Aluminium is lighter and suits larger housings, while zinc gives finer detail, thinner walls and better plating for small parts.
How much does a die-casting die cost?
Die cost depends on part size, cavities and slides, and is higher than sand-casting patterns. Get a quote that states the guaranteed die life.
Can die castings be anodised?
Die-cast aluminium does not anodise well because of its silicon content. Powder coating, e-coating or plating are better choices.
