Rapid Prototype Lost Wax Casting

YOUR PROTOTYPE MANUFACTURING PARTNER

Pahwa MetalTech is an Investment Casting manufacturing facility equipped with advanced air and vacuum melting furnaces  to manufacture high quality castings in Copper alloys (e.g. Bronzes, Brass, OFC Copper etc), Aluminum alloys ( LM alloys) and Stainless Steels ( e.g SS 304, SS 316, 17-4PH etc.). Our manufacturing technology is well suited to manufacture high-integrity, low volume castings for prototypes and product development. 

ZERO TOOLING COST

We adopt the most advanced manufacturing technologies and simulation techniques to make prototypes via Investment casting (or lost wax) in Aluminium, Copper, and stainless steel-based alloys with ZERO tooling costs. By using 3D printed patterns in materials like PLA and special castable resins and adopting processes like FDM and Stereolithography (SLA) we achieve high-quality consumable patterns without investment in hard tooling.​ Our flexible manufacturing setup can produce single-piece casting to a few hundred components quickly for prototyping needs.

FAST-TRACK YOUR DEVELOPMENT

When developing a new component, it often takes a couple of trials to reach the most optimized design of your product. Now fast-track your product development process with our innovative and flexible lost wax manufacturing process, whether you want to produce multiple design options together or iterate one after another, you can get quick prototype parts for development & prototype trials. This process is not limited to castings, but also develop prototypes for assemblies and forging components. 

COST EFFECTIVE

Evaluating 3D Metal Printing (or Rapid Prototyping) as an option for your prototype needs? Our Investment Casting technology can manufacture very high-quality castings with the ability to produce complex geometries and thin-walled castings at a much lower cost as compared to Metal 3D Printing or Rapid Prototying. This cost equation becomes even more economical in the favor of investment casting when you have to manufacture in multiple quantities.

Generatively Designed Lost Wax Castings

OPTIMISE WEIGHT WITH GENERATIVE DESIGNS

Generative Design is increasingly being used by companies to optimise the weight-to-strength ratio of engineering parts. Often designs have to be compromised considering the constraints of the conventional manufacturing process or use a more expensive 3D metal printing process. With our Vacuum Investment Casting technology, we can cast generative design parts which reduces material & machining cost and improve product performance. This technology also helps companies aid sustainability and environmental goals of using less material and energy. 

LOOKING TO DEVELOP PROTOTYPES?

We are just not an another Investment Casting foundry. Equipped with an in-house design with our advanced manufacturing technology and process control we can manufacture high integrity castings for your prototype and production needs.
