What preparations are there for stainless steel water pump castings during production

In the production process of stainless steel water pump castings, it is crucial to ensure the accuracy and efficiency of each link. The following is the professional process we follow at Ningbo Etdz Andrew Precision Cast Co., Ltd. to provide customers with high-quality casting products.

Drawing Review and Technical Preparation
The first step in the production process is to conduct a comprehensive review of the drawings provided by the customer. Our team of engineers will conduct a detailed analysis of the drawings to deeply understand the key information such as the geometry, size specifications, material requirements and production batch of the castings. On this basis, the team develops a detailed casting process plan. This plan covers multiple aspects such as the selection of casting methods, the design of the gating system, and the determination of the cooling method. At the same time, engineers will identify potential process difficulties based on the characteristics and intended use of the castings, and formulate corresponding solutions in advance. The rigor of this stage lays a solid foundation for subsequent production.

Mold Design and Manufacturing
The mold is the core tool in the casting process, which directly affects the shape and dimensional accuracy of the casting. In our company, there is a professional mold design and manufacturing team. Based on the reviewed drawings, the team uses advanced CAD/CAM software to design the mold to ensure that the mold structure is reasonably designed and the dimensions are accurate. The mold manufacturing process uses high-precision machine tools to ensure that the surface finish and dimensional accuracy of the mold meet the production standards. After the mold is manufactured, we will conduct strict quality inspections and mold trials to ensure that the function and quality of the mold meet industry standards.

Raw material procurement and inspection
The quality of stainless steel water pump castings is directly related to the quality of the raw materials used. Therefore, in the procurement of raw materials, we adopt strict screening standards. We establish long-term cooperative relationships with suppliers with good reputation and stable quality, and sign detailed procurement contracts. After the raw materials arrive, it is our necessary process to conduct a comprehensive inspection, including chemical composition analysis and mechanical property testing, to ensure that the raw materials meet production requirements. For unqualified materials, we will resolutely return them and hold the relevant suppliers accountable to maintain high standards of product quality.

Production facilities and equipment inspection
Before officially starting the production of stainless steel water pump castings, all production facilities and equipment must be fully inspected. This inspection includes key equipment such as melting furnaces, molding machines, pouring machines and sand processing equipment. We will carefully check the operating status of the equipment, whether the control system and safety protection devices are intact, and perform maintenance and maintenance when necessary. In addition, the cleanliness and safety of the production site are also our focus. Regular cleaning and tidying up ensures the efficiency and safety of the production environment.
