Our Expertise
Our Investment Casting Technologies
Air Melting

We offer Air Melting Investment Castings for non-ferrous - Copper and Aluminum and stainless steel alloys, ensuring reliable quality and performance. Ideal for general engineering and industrial applications, this process is both efficient and cost-effective.
Vacuum Melting

We offer Vacuum Investment Castings for high-performance applications requiring superior purity and precision. Ideal for aerospace and critical engineering components, this process ensures low gas entrapment and excellent metallurgical integrity.
Design & Simulation
At Pahwa MetalTech, we specialize in in-house design of precision tooling for wax investment casting using advanced CAD/CAM systems. We conduct solidification and simulation studies to optimize casting parameters and eliminate defects. This ensures consistent, high-quality castings with excellent dimensional and metallurgical integrity.

Engineering Excellence in Every Step
Beyond casting, we offer end-to-end solutions including critical heat treatment, precision machining, and surface preparation—delivering ready-to-use parts.
Heat Treatment
Our in-house heat treatment furnaces enhance the mechanical properties of cast components, ensuring they meet precise application requirements.
Machining
Leveraging our expert supplier base, we offer fully machined components, delivering ready-to-assemble parts that meet tight dimensional and quality standards.
Surface Treatment
We offer end-to-end solutions to meet the technical requirements of any surface treatments and plating, ensuring components are finished to exact specifications.

Rapid Prototyping
We leverage 3D Printed PLA patterns for Investment Casting, enabling rapid prototyping and the production of extremely low-volume or complex parts where traditional tooling isn't feasible. This approach allows for faster development cycles, reduced costs, and greater design flexibility. It's ideal for validating designs, producing legacy components, or manufacturing intricate geometries without the need for hard tooling.
