Precision investment casting Services
Silica Sol Investment Casting
Silica sol investment casting is a casting process that is widely used in stainless steel and alloy steel casting parts. Silica sol is used as a binder to build a ceramic shell on the outer surface of the wax mold. It has the characteristics of high precision (CT4~CT6) and good surface finish. The foundry field plays an important role.
Supro MFG is a professional investment casting companies, we utilize silica sol casting for casting parts such as high temperature heat resistant alloys, heat resistant steels, stainless steels, carbon steels, low alloys, aluminum alloys and copper alloys.
Water Glass Investment Casting
Water glass investment casting is a casting process in which water glass is used as a binder to wrap the ceramic shell of the wax mold. The accuracy is better than that of sand casting, but the surface finish is poor. It is suitable for parts with heavy weight or no strict requirements on the external surface. .
At Supro MFG, we rely on water glass investment casting with low material cost and high forming efficiency for part casting of heavier or stronger products with more complex shapes. Such as: agricultural machinery, gears, large bases, and civil engineering components.
DLP 3D printed wax investment casting
3D printing wax investment casting is an advanced casting process that fills the gap. It can quickly build SLA models through 3D printing technology to meet the casting needs of small batches, high precision and low cost, reduce the investment in molds and production cycles, and increase the demand for rapid prototyping and production. Small batch casting brings huge economic benefits.
As an advanced investment casting company, Supro MFG provides high-precision SLA 3D model casting services, providing cost-effective metal casting solutions for casting prototypes and small batch castings. Such as: precision gears, jewelry, models, small art sculptures, etc.
vacuum investment casting
Vacuum investment casting is the process of completing precision casting in a vacuum state, which can effectively prevent the metal solution from rolling in the ceramic cavity and the pores generated after bursting, which brings internal defects and complex details that cannot be filled to the metal casting.
Supro Investment casting companies provide vacuum investment casting services for thin walled castings as well as castings with intricate details, ensuring that the castings maintain high precision and a very smooth surface.

what is precision investment casting ?
Metal Investment casting, also known as: lost wax casting, is one of the popular metal precision casting processes in the manufacturing industry. The industrial or household wax is molded through a mold, connected into a tree-like structure, and a multi-layer ceramic shell containing silica sol or water glass is wrapped on the outer layer. Metal casting is performed after drying.
Investment casting parts have many advantages to accurately create complex structure of product casting structure and shape, as close as possible to the final shape, compared with traditional sand casting, investment casting parts are more accurate in size and have a better surface finish to reduce precision processing cost.
- Offers greater flexibility in design.
- Provides more details on complex structures.
- Affordable low cost casting molds.
- Multiple alloy options to enhance the performance of cast parts.
- Surface finish Ra 3.2.
- Precision tolerance Min ±0.15mm.
- High-volume casting maintains consistent high-quality delivery.

Retrofitting old equipment? No parts design drawings?
Metal investment 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 investment 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 investment castings, steering projects towards greater cost-effectiveness.
Product Design & Optimisation – 3D Printing Rapid Prototyping – Prototype investment Casting – Installation & Testing
Metal investment casting Product Design & Optimisation
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 wax 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 investment 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.
