Custom Metal Foundry Casting Service Precision CNC Machining Brass Investment Casting Parts Pressure Casting

As a specialized custom metal foundry, we provide comprehensive manufacturing solutions integrating precision brass investment casting, pressure casting, and CNC machining services. Our integrated approach combines traditional casting expertise with modern machining technology to deliver high-quality brass components that meet the most demanding specifications across various industries.

Material Excellence: Brass Alloys Selection

We specialize in processing high-performance brass alloys, primarily:

• C85700 (Yellow Brass): Offering excellent machinability and good corrosion resistance

• C87500 (Silicone Brass): Providing superior strength and excellent casting fluidity

• C93200 (Bearing Bronze): Delivering excellent wear resistance and low friction properties

These materials demonstrate outstanding mechanical properties including tensile strength ranging from 275-550 MPa, excellent corrosion resistance in various environments, and superior thermal and electrical conductivity. The natural antimicrobial properties of brass make it particularly suitable for medical and food processing applications.

Advanced Manufacturing Processes

Our manufacturing capabilities encompass two primary casting technologies complemented by precision machining:

Investment Casting Process
Utilizing the lost-wax technique, we produce complex, near-net-shape brass components with exceptional surface finish and dimensional accuracy. This process enables:

• Production of intricate geometries with tight tolerances (±0.125mm per 25mm)

• Excellent surface finishes (typically 3.2μm Ra or better)

• Minimal machining requirements and material waste

Pressure Casting Technology
Our pressure casting capabilities deliver high-production efficiency while maintaining quality consistency through:

• Rapid production cycles with automated systems

• Enhanced dimensional stability and repeatability

• Reduced porosity and improved mechanical properties

Precision CNC Machining
Our comprehensive machining department provides complete secondary processing:

• 3, 4, and 5-axis CNC machining centers

• Precision drilling, tapping, and milling operations

• Tight tolerance maintenance (±0.01mm)

• Deburring and surface treatment capabilities

Quality Assurance and Technical Standards

We maintain rigorous quality control throughout our manufacturing process:

• Material certification and traceability

• First article inspection and in-process quality checks

• CMM verification for critical dimensions

• Pressure testing and leak detection

• Surface finish and roughness measurement

• Compliance with ISO 9001 quality standards

Industrial Applications and Solutions

Our brass components serve diverse industry sectors:

• Plumbing and HVAC: Valve bodies, fittings, and connector components

• Marine and Offshore: Corrosion-resistant hardware and naval architecture elements

• Electrical and Electronics: Connectors, terminals, and electromagnetic components

• Architecture and Construction: Decorative hardware and structural elements

• Medical Equipment: Antimicrobial components and instrument housings

By integrating advanced casting technologies with precision machining capabilities, we deliver complete manufacturing solutions from prototype development to mass production. Our engineering team works closely with clients to optimize designs for manufacturability, performance, and cost-efficiency, ensuring reliable brass components that exceed industry standards and customer expectations.
