Production Process
Stainless steel casting parts manufacturing involves a series of production processes in order to get finish products from raw materials. Weizhen Hi-tech has full in-house production facilities for the whole process, which strengthens Weizhen’ s abilities to meet customer needs with consistent quality control and quick turnaround time.
Smelting and AOD Refining
Weizhen is uniquely equipped with AOD furnace for the refining of molten metal besides normal medium-frequency induction furnaces. The molten metal after refining is much more pure with super low carbon, phosphorus, and sulfur content, providing better mechanical and chemical performances for the casting parts.
Pouring & Casting
Weizhen is focused on large size high complex stainless steel casting. The maximum casting weight is up to 15000kgs. Weizhen is especially good at casting of duplex stainless steel, super duplex stainless steel, Austenitic stainless steel and nickel based steel. The main alloy number include NAS 329J3L, UNS S32205/S31803, DIN/EN 1.4462, ASTM A240, ASME SA-240, 2304, S32003, 2205, 2507, S32707, UNSS32304, EN1.4362, S32205-EN1.4462, S32750, EN1.4410, etc.
Heat Treatment
Heat treatment is critical to the properties and quality of steel castings. Weizhen is equipped with advanced 1200 °C heat furnaces and solution pools. The casting parts are precisely heat treated and solution annealed to achieve desired properties.
Machining
Weizhen is equipped with all sorts of machining equipment for the processing of stainless steel casting parts and components. State-of-the-art cutting machine, shot blasting machine, horizontal lathe, CNC horizontal lathe, CNC vertical lathe, CNC Gantry milling machine, Radial drilling machine, Digital display boring and milling machine are all installed in the factory. The products could be delivered as cast, rough machined or finish machined.
Inspection & Testing
Casting parts need to be tested and inspected before delivering to customer. Weizhen conducts strict checking and testing through out the whole production process to ensure best product quality and customer satisfaction. The tests and inspections Weizhen provides include, but not limited to, chemical analysis, physical properties, dimensions, PT, RT, three coordinates, 3D Scan.
Certification
With committed responsibilities to customer, employees, the society, and the environment, Weizhen is certified and strictly operates with multiple management systems to ensure a sustainable future. The main certification includes ISO9001 quality management system, EU product CE certification, ISO14001 environmental management system certification, OHSAS18001 occupational health and safety management system certification, GB/T29490 intellectual property management system certification, and ISO19600 compliance management system certification.
