——Custom Metal Prototype Casting Services
Retrofitting old equipment? No parts design drawings?
Metal casting part models are pivotal at the outset of any project. However, for innovative creations by entrepreneurs or retrofitting of outdated equipment, the absence of part design drawings or 3D models presents a significant challenge for many engineers and innovators. This leaves numerous clients at a loss, unsure how to proceed with their metal casting projects.
Supro MFG specialises in bespoke metal casting part design and foundry techniques, enabling us to actively engage in the product design phase. Based on your functional requirements and environmental constraints, we provide timely professional guidance and refine preliminary designs for metal castings, steering projects towards greater cost-effectiveness.
Product Design & Optimization – 3D Printing Rapid Prototyping – Prototype Casting – Installation & Testing
Metal casting Product Design & Optimization
We proactively provide metal casting component design solutions for users lacking design drawings or possessing incomplete schematics. Whether you have only a concept or a simple hand-drawn sketch, we can optimise your project design from an application functionality perspective.
This encompasses: 3D scanning, manual measurement, CMM measurement, and more. We will continue until comprehensive design documentation is created. This approach will save you development costs and ensure a smooth process.


3D printing rapid prototyping
We provide industrial-grade, high-precision 3D printing rapid prototyping services to test the design rationality and functionality of your products, or to swiftly create wax models in preparation for subsequent rapid casting.
The primary 3D printing technologies involved in rapid prototyping are:
- SLS PA8200 nylon printing
- SLA photopolymer resin printing
- MJF black PA12 nylon printing
- SLM aluminium and stainless steel metal printing
- DLP wax pattern rapid printing
For 3D printing quotations, please provide STL, STP, STEP, XTP, IGES, or OBJ format files modelled in 3D software such as ProE/UG/3DMAX/MAYA/ZBrush/Rhino.
Metal prototype casting services
supro MFG provides rapid prototyping casting services, enabling you to advance prototype part designs through testing phases without investing in costly, complex moulds. Utilising advanced 3D printing wax mould technology (DLP 3D printing), we directly print 3D wax models from CAD files. Precision mould cavities are then formed using plaster, enabling faster, more efficient design validation. This ensures the final product meets your specifications and prevents misdirected investment.
