Company Profile

Hangzhou Chunjiang Lead -free copper casting company is located on the beautiful Fuchun River. It is a professional environmentally friendly lead -free copper casting manufacturer. At present, the company mainly produces various leading bronze castings, bronze water cases, bronze valves, bronze pumps, bronze ship valves, bronze mechanical parts, etc.; The company has hired a number of projects with many years of production of bronze castings since its establishment for more than ten years. Technical staff, tirelessly engaged in production and technology research and development of various bronze castings (especially lead copper). The company can provide customers with dozens of materials cards from previous single materials to now, covering several major fields such as leading lead bronze, silicon bronze, aluminum bronze, and tin bronze; Actively adapt to the requirements of European and American customers in environmental protection. In the past few years, it has developed a number of lead -free copper products, and the quality has fully met customer requirements. The product supply is in short supply.

The company currently has a set of advanced casting production flow lines and process processes. The company strictly controls the production process, comprehensively implements 6S management at the production site, mature production processes and strict on -site management to provide a strong guarantee for qualified castings; the melting uses non -polluting and environmentally friendly mid -frequency core induction electric furnace to ensure the quality of copper liquid; The production model of automatic modeling machine and semi -automatic modeling machine, the inner core uses environmentally friendly membrane sand, so that the quality of the casting surface is smooth and delicate to meet customer needs;

The company's detection instrument is improved: casting component testing is used using the German OBLF direct reading spectrometer for pre -furnace and after the furnace double analysis to ensure that the composition of the casting meets the standard requirements; the mechanical performance test uses a microcomputer -liquid universal test machine to stretch the test rod to be the castings for the casting. Provide accurate mechanical performance parameters; 400 times the gold phase microscope provides internal gold phase organizations; for special needs, you can also provide customers with non -destructive detection; perfect sand -type experimental instruments fully ensure the sand -shaped performance; the fast thermocouple can provide the operator with Accurate pouring temperature. Make sure that there are no defects for casting.

The company's main raw materials use 99.99%electrolytic copper, tin, lead, A00 zinc, A00 aluminum, nickel, manganese, pupae and other raw materials; synthetic raw materials mostly use copper ingots imported from the United States to ensure quality.

The company can cast a variety of high -performance, high -precision, high conductivity, high -strength, and difficult copper alloy castings according to customer drawing requirements (or samples).
