Production Process
Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold, causing the metal liquid to undergo centrifugal motion to fill the mold and form the casting. Due to centrifugal motion, liquid metal can fill the mold radially and form a free surface of the casting. Without a core, cylindrical inner holes can be obtained, which helps to eliminate gases and inclusions in the liquid metal and affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.
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.
Vertical Centrifugal Casting
Decanter Centrifuge End Hub is normally made by vertical centrifugal casting. Weizhen possesses a large collection of centrifugal casting molds and is ready to cast virtually any size required for decanter centrifuges.
Heat Treatment
Heat treatment is critical to the properties and quality of the steel castings. Weizhen is equipped with advanced 1200 °C heat furnaces and car type furnaces for the heat treatment. The casting parts are precisely heat treated to achieve the desired properties inside the factory.
Machining
Weizhen is equipped with all sorts of machining equipment for the processing of stainless steel casting parts and components, from cutting, honing, turning, milling, to drilling and grinding.The fully set up facilities and capabilities enables Weizhen to provide customers with a highly reliable one stop service. The parts can be delivered as cast, rough machined or finish machined.
Inspection & Testing
Product testing and inspection is essential for the quality of casting parts. Weizhen conducts strict checking and testing through out the whole production process. Weizhen runs a series of chemical and physical testing, NDT testing, dimensional inspection to ensure each product meet customer requirements and standards.
Certification
With committed responsibilities to customer, the society, employees and environment, Weizhen is certified and strictly operates with multiple management systems to ensure a sustainable future. The main certification includes GB/T19001 (ISO9001) quality management system certification, EU product CE certification, GB/T24001 (ISO14001) environmental management system certification, GB/T28001 (OHSAS18001) occupational health and safety management system certification, GB/T29490 intellectual property management system certification, and GB/T35770 (ISO19600) compliance management system certification.
