brass casting parts

About Us

We specialize in custom casting and precision machining, offering end-to-end solutions for brass alloy components. Leveraging advanced brass alloy casting technology, we deliver high-performance parts with exceptional corrosion resistance and durability. Our services include custom manufacturing from drawings (ODM/OEM) and prototyping from samples, ensuring unique designs tailored to your specifications.  


With in-house mold development and production capabilities, we guarantee seamless transition from concept to mass production. Whether complex geometries or tight tolerances, our CNC machining expertise ensures 100% compliance with your new product development needs. Trust us to transform your ideas into precision-engineered brass components, backed by rigorous quality control and fast turnaround.

The Advantage of Custom Precision Machined Casting Products: 




  • Accurate adaptation to requirements

Support the best drawing/sample processing, 1:1 restoration of customer design, to meet the unique needs of non-standard parts and complex structural parts, to avoid the problem of inadequate adaptation of standard parts.


  • High cost controllability 

Flexible choice of materials (such as HPb59-1 brass, aluminum alloy, etc.) and processes (die casting/sand casting) to optimize the cost per piece;

Mold development costs can be allocated to bulk orders to reduce initial investment.


  • Quality and performance guarantee

Precision casting +CNC secondary processing to ensure dimensional accuracy (±0.05mm) and surface finish (Ra≤1.6μm);

Material properties can be customized (e.g. corrosion resistance, high strength) according to ASTM/ISO standards.


  • Fast response and delivery

Provide the fastest mold opening (3-4 weeks) and small batch trial production service to accelerate new product development cycle and support market verification.


  • Whole-process technical collaboration 

From design optimization, mold development to mass production, technical team support to ensure 100% compliance with customer technical expectations and reduce development risks.

FAQ


1Q: What is the minimum order size (MOQ) for custom casting products? 

1A: We support flexible orders, small batch trial production MOQ can be as low as 50-100 pieces, mass production orders according to mold cost optimization suggestions.


2Q: How long does it take from design to delivery? 

2A: The standard cycle is 4-6 weeks (including 3 weeks for mold development + 1-3 weeks for production), and urgent orders can be compressed to 3 weeks. Provide phased progress feedback to ensure transparency and control.


3Q: What are the advantages of brass over other materials (such as aluminum alloy)? 

3A: Brass (such as HPb59-1) has higher strength, corrosion resistance and electrical conductivity, suitable for high pressure/wear resistance scenarios such as valves and sanitary ware; Aluminum alloy is lighter and suitable for radiators and structural parts.


4Q: How to ensure the dimensional accuracy and quality consistency of customized parts? 

4A: Precision casting +CNC secondary machining, key dimensional tolerance control ±0.05mm, the whole process through CMM detection, surface roughness meter and pressure test, in line with ASTM/ISO standards.


5Q: If the product does not match the design drawing, how to deal with it? 

5A: We promise to accept 100% according to the drawing and provide the first article inspection report(FAI). In case of deviation due to process problems, free rework or remake, and bear the associated logistics costs.
