Our Non-Ferrous Casting Process at a Glance
As non-ferrous casting manufacturers in India, we follow a proven investment casting process to ensure consistency and precision.
As a non-ferrous foundry in India, our casting methodology is material agnostic. We are an investment casting foundry and the fundamental steps stay the same for Brass, Gunmetal, Inconel, and Hastelloy.
Precision Molding
Initiates accurate tooling and establishes preliminary geometry.
Dewaxing
Melts the wax in the ceramic shells to obtain perfect cavities—simple and complex.
Controlled Pouring
Achieves an even material spread with the help of gravity.
Machining
Ensures exact geometry, tight tolerances, and excellent surface finish.
Inspection
A range of visual, chemical, and physical checks to ensure 360° compliance.

FAQs
Is there support for rapid prototyping?
Yes, we provide rapid prototyping to help you move quickly from design to first article.
What weight and tolerance do you work with?
We cast from 1 to 30 kg and target tolerance between CT 4 and 7. The actual tolerance depends on the design and the component’s complexity.
Do you provide material testing?
Yes, we provide material testing as an integral part of the manufacturing process. Additionally, we furnish a material testing certificate (MTC) with every consignment.
How do you ensure accuracy during final testing?
We use a range of machines to ensure accuracy, integrity, and product-application fit. Coordinate-measuring machines establish accuracy, universal testing machines and spectro-mechanical machines check for integrity, and VMCs ensure tight tolerances.
Choosing an experienced non-ferrous casting supplier helps you manage project costs without compromising on quality.
