CuZn37 Brass Die Casting Solution for Pump System Switch Housing Components
Project Overview – Demands on Switch Housings in Fluid Control Equipment
Switch housings used in pump and valve systems must provide mechanical strength, thermal conductivity, and chemical resistance. These enclosures often house sensitive electrical or mechanical actuation components and require dimensional accuracy and environmental durability. CuZn37 brass die casting offers an optimal solution for switch housing applications, delivering robust performance in aggressive environments while supporting precise post machining and surface conditioning.
Material Selection – Why CuZn37 Brass is Ideal for Switch Housings
CuZn37, a 63/37 brass alloy, offers excellent mechanical strength, corrosion resistance, and wear performance. Its high zinc content enhances castability and surface smoothness. CuZn37 is also resistant to dezincification and stress cracking—common issues in fluid handling systems—making it well-suited for electrical switch housings exposed to moisture, lubricants, or pressure media.
Manufacturing Process Breakdown
Copper Alloy Die Casting with CuZn37
Using copper die casting, we form structurally rigid switch housing shells with internal ribs, mounting bosses, and sealing flanges. Molds are optimized for flow and cooling behavior, minimizing internal porosity and maintaining dimensional consistency within ±0.1 mm.
Post Machining for Precision and Assembly
Post machining refines key surfaces such as gasket flanges, threaded ports, and interface slots. We maintain sealing surface flatness within ±0.05 mm and ensure clean alignment for mating electrical or pneumatic modules. Multi-station CNC setups are used for tight-tolerance bores and counterbores.
Surface Finishing – Uniform Sandblasting
To enhance visual consistency and surface bonding for seals, sand blasting is applied. This results in a matte surface with controlled roughness (Ra 2.0–3.0 μm), removing any minor casting residues and preparing the surface for painting, coating, or gasket integration if required.
