Copper Casting

Copper Casting

We are one of the leading producers of Copper Casting Components from India. We have been supplying superior‑quality Copper castings to both domestic and international markets for over 29 years. Our foundry in Jamnagar, Gujarat is equipped with advanced sand‐casting and investment‐casting facilities capable of handling parts up to 20 kg. We specialize in electrical castings, pump parts, impellers, bushes, and other complex geometries. Post‑casting CNC machining is available in‑house at very competitive prices, ensuring tight tolerances, excellent surface finish, and full-service supply.

Product Overview

Copper Castings are precision‑molded components produced by pouring molten copper alloys into sand or investment molds. Known for exceptional electrical and thermal conductivity, corrosion resistance, and mechanical strength, copper castings are essential in electrical switchgear, pump assemblies, heat exchangers, marine hardware, and industrial machinery.

  3. Investment Casting – Wax patterns & ceramic shells

  4. Shakeout & Fettling – De‑sanding, flash removal

  5. Heat Treatment (if required)

  6. CNC Machining – Turning, milling, drilling, boring

  7. Deburring & Surface Finishing

  8. Inspection & Testing – Dimensional, metallurgical, and NDT

Tolerances & Surface Finish

Feature Tolerance Finish (Ra µm)
Linear Dimensions ± 0.3% of nominal 3.2 – 12.5 (as‑cast)
Machined Surfaces ± 0.02 mm 0.8 – 3.2
Roundness & Cylindricity 0.05 mm N/A
Weight Variation ± 3% N/A

Turnaround Time

  • Standard Sand Castings: 4–6 weeks

  • Investment Castings & Tooling: 6–8 weeks

  • CNC Machining & Delivery: Additional 2–3 weeks

  • Expedited Services: Available upon request
