Production Process
Pulper impeller or pulper rotor are made by sand casting in one piece. The blanks are then machined to exact specifications. 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. The molten metal after refining is much more pure with super low carbon, phosphorus, and sulfur content, providing better mechanical and chemical performances. Weizhen can pour and cast super low carbon steel, duplex stainless steel, super duplex stainless steel, nickel based steel with quality guaranteed.
Pouring & Casting
Weizhen is focused on large size high complex stainless steel casting. The maximum casting weight is up to 15000kgs. Weizhen is especially strong 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.
Machining
Weizhen is equipped with all types of machining facilities 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 fully set up facilities enables Weizhen to provide customers with a highly convenient and efficient one-stop service. The parts can be delivered as cast, rough machined or finish machined.
Inspection & Testing
Casting parts are tested and inspected before delivering to customer. Weizhen applies strict inspection and testing through out the whole production process to ensure best product quality and customer satisfaction.
