Our Brass Casting Process Capabilities

Selecting the Right Method for Your Specific Part Geometry

As a dedicated OEM metal casting supplier, we don’t force a single manufacturing method on every project. Instead, we evaluate your technical drawings, volume requirements, and budget to determine the most efficient production route. Brass and copper alloys have unique flow rates and cooling properties, meaning the choice between non-ferrous metal casting techniques is critical for achieving the correct mechanical properties and surface finish. We leverage decades of experience to match your design with the process that minimizes waste and maximizes structural integrity.

We categorize our capabilities into three primary streams to cover the full spectrum of industrial needs:

• Precision Investment Casting: Also known as lost wax casting, this is our go-to for complex, intricate designs requiring tight tolerances and smooth finishes. It significantly reduces the need for secondary machining.
• Sand Casting: The most cost-effective solution for large, heavy components or lower-volume runs. This method is robust and versatile, ideal for industrial equipment and heavy machinery parts.
• Die Casting: Perfect for high-volume production where consistency, speed, and dimensional stability are paramount.

Whether you are looking for a custom brass fittings manufacturer or need heavy-duty pump components, our engineering team ensures the selected process aligns perfectly with your functional requirements.

Brass Investment Casting (Lost Wax)

When your project demands complex geometries or intricate internal structures, our lost wax brass casting process delivers the precision you need. We utilize this method to produce near-net-shape components, significantly reducing the need for secondary machining. This approach is ideal for parts requiring thin walls and fine detail that sand casting simply cannot achieve.

Our precision investment casting capabilities include:

• Tight Tolerances: We achieve high-precision dimensions up to ±0.05mm, ensuring consistent fit and function for critical assemblies.
• Complex Geometries: Perfect for undercuts, internal channels, and elaborate designs often found in decorative hardware, lock bodies, or specialized industrial valves.
• Superior Surface Finish: Delivering a smoother surface (typically Ra 3.2–6.3) compared to other casting methods, which drastically cuts down on polishing costs.
• Material Versatility: We expertly cast various grades, including C83600 red brass casting alloys and silicon bronze, tailored to your specific mechanical requirements.

Brass Sand Casting (Resin & Green Sand)

For larger, heavier parts where investment casting isn’t practical, our brass sand casting foundry services offer the perfect balance of cost and performance. We utilize both green sand and resin sand processes depending on your specific surface finish and budget requirements. Green sand is the go-to for keeping costs down on simpler shapes, while resin sand provides higher dimensional stability and a smoother finish for more complex industrial brass components.

This method significantly lowers tooling costs compared to die casting, making it a smart choice for low-to-medium volume production. It is the standard solution for manufacturing heavy-duty parts like large pump housings, marine hardware, and fluid handling valves that require the durability of red brass or bronze without the expense of high-precision molds.

Brass Die Casting (Gravity & Pressure)

When scaling up production for industrial brass components, consistency and speed become critical. We utilize brass die casting methods to deliver high-volume runs that maintain strict dimensional stability while keeping per-unit costs down. This approach is ideal for parts that require a better surface finish than sand casting but need faster production cycles than investment casting.

We offer two distinct die casting solutions depending on your volume and mechanical requirements:

• Gravity Die Casting Brass: Molten metal is poured into a permanent metal mold using gravity. This method produces parts with excellent mechanical properties and a finer grain structure, making it perfect for pressure-tight components like valves and pumps.
• Pressure Die Casting: Metal is injected into the mold under high pressure. This is the go-to choice for complex shapes with thinner walls and high-precision requirements, ensuring rapid cycle times for mass production.

As a dedicated non-ferrous metal casting partner, we help you determine which die casting method aligns best with your project’s budget and technical specifications.

Common Brass & Bronze Alloys We Cast

Selecting the right material is critical for part performance. We strictly adhere to ASTM and ISO standards to ensure our copper alloy casting meets the rigorous demands of the US market. Whether you need high corrosion resistance for marine environments or excellent machinability for complex fittings, we source and test the exact grade required for your project.

Our foundry specializes in a wide range of industrial brass components, with a focus on the following standard alloys:

Alloy Grade (ASTM)	Common Name	Key Characteristics	Typical Applications
C83600	Red Brass (85-5-5-5)	Excellent machinability, moderate strength, and good corrosion resistance.	C83600 red brass casting is ideal for valves, pump housings, and low-pressure fittings.
C85400 / C85700	Yellow Brass	Superior aesthetic finish; polishes well to a golden shine.	Decorative hardware, plumbing fixtures, and architectural trim.
C87300 / C87600	Silicon Bronze	High strength and exceptional resistance to saltwater corrosion.	Marine bronze casting parts, pump impellers, and heavy-duty electrical connectors.
C95400	Aluminum Bronze	High tensile strength, wear resistance, and durability under load.	Bearings, gears, and wear plates.

We also accommodate custom material requests. If your engineering team specifies a unique bronze or brass composition to handle extreme temperatures or specific chemical environments, we can adjust our melt to match your exact specifications.

Precision CNC Machining & Secondary Operations

Raw castings provide the fundamental shape, but precision machining ensures the functionality and fit required for high-performance applications. We handle the entire production cycle in-house, transforming raw metal into CNC machined brass parts that are ready for immediate assembly. This integrated approach significantly reduces lead times and eliminates the logistical risks of moving parts between a foundry and a separate machine shop.

While various casting methods offer excellent near-net shapes, our secondary operations allow us to achieve tight tolerances (up to ±0.05mm) that casting alone cannot match. We utilize advanced turning, milling, and drilling equipment to finalize critical dimensions on valve bodies, fittings, and custom hardware.

Our Value-Added Finishing Services:

• Precision Machining: Full CNC capabilities for intricate details and threaded features.
• Surface Treatments: Professional metal casting surface finishing including polishing, sandblasting, and powder coating.
• Plating: Chrome, nickel, and zinc plating options to enhance corrosion resistance and aesthetics.

By combining casting and machining under one roof, we deliver a cost-effective, “ready-to-use” solution tailored to your engineering standards.

Quality Assurance & Inspection Standards

At Precision Vast, we understand that consistent quality is critical when sourcing brass metal casting components. We operate strictly under ISO 9001:2015 standards, ensuring that every part we produce meets international engineering benchmarks. Our quality control isn’t just a final step; it is integrated into every stage, from the initial wax pattern to the final surface finishing.

To guarantee that your parts meet precise specifications, we utilize advanced testing equipment and protocols:

• Spectrometer Analysis: We perform chemical analysis on every melt to verify the exact composition of the copper alloy casting. This ensures the material grade (whether Red Brass, Yellow Brass, or Bronze) matches your requirements perfectly.
• CMM Testing: Our Coordinate Measuring Machines (CMM) verify complex geometries and dimensional accuracy, ensuring we hit tolerances as tight as ±0.05mm.
• Mechanical Property Testing: We conduct tensile, hardness, and elongation tests to ensure the non-ferrous metal casting can withstand the physical demands of your application.
• 100% Final Inspection: Every batch undergoes a visual and dimensional check before packaging to prevent defects from reaching your facility.

Understanding these rigorous checkpoints is essential to grasping a complete overview of the casting process, as they ensure that the final components are structurally sound and ready for assembly.
