\nEnergy Casting Components We Deliver\n<\/h2>

\nEvery energy application has unique requirements. Here is the full range of power-generation castings we produce -- each with proven processes, qualified materials, and documented case studies.\n<\/p>

\n<\/rect><\/circle><\/svg>\n<\/div><\/div>

\nGIS Shell Castings (126KV - 1100KV)\n<\/h3>

\nGas-insulated switchgear shells are our flagship energy product. We use 3DP sand molds for rapid prototyping (5 to 7 days per set), then transition to metal mold low-pressure casting for serial production at 200 plus sets per month. Every shell passes helium leak detection, X-ray inspection, and air-tightness testing. Zero defects required on sealing surfaces -- a standard we have consistently met for Pinggao Group, Korea LS, and Korea ILJIN.\n<\/p>
