Technical introduction of precision casting stainless steel

The old-style precision casting stainless steel plate shock-type or shock-type molding machine production line has insufficient productivity, high labor efficiency and high noise, and is not suitable for many production regulations. It should be gradually updated in many aspects. For small and medium-sized castings, the boxless high pressure molding machine production line that can be used for horizontal clinical diagnosis or vertical clinical diagnosis can be selected. The solid molding production is highly efficient and high, and it takes up a small area; for medium parts, various types of boxed molding machines can be used. Compression molding machine production line and air-punch molding line are integrated into the requirements of rapid and high-precision molding production line. Core-making methods can be high-efficiency core-making methods such as cold core boxes, hot core boxes, and shell cores. Medium-level large quantities of large and medium-sized precision cast stainless steel plates can be considered to use epoxy resin self-hardening sand for molding and core making. For super heavy castings produced in small batches, hand-made modeling is still the key method. Hand-made modeling can incorporate a variety of complicated regulations, which is more flexible, and does not require many processing technology weapons and equipment. Can use sodium silicate sand mold, VRH method sodium silicate sand mold, organic chemical ester sodium silicate self-setting sand mold, clay dry type, epoxy resin self-setting sand mold and concrete sand mold, etc.; for super heavy castings produced from loose parts, pits are selected The modeling method is low-cost and quick to build and put into production.
Bottom pressure casting, aluminum die casting, suction filtration casting and other casting methods are only suitable for mass production because of the relatively expensive machinery and equipment and abrasive tools. The standard method should be suitable. For example, it is to produce large and medium-sized CNC lathe bed bodies and other castings. Generally, the core assembly method is used, and the shape and sand box are not made, and the core is assembled in the pit; and other processing plants use the sand box modeling method. , Make a look.
Different companies have different production standards, production habits, and accumulated work experience. Based on this standard, consideration should be given to what products are suitable and unsuitable. Precision regulations and costs The precision of castings obtained by various casting methods is different, the initial project investment and productivity are not consistent, and the final economic benefits are also different. Therefore, to ensure more, fast, better, and economical, it should be applied to all fields. Resolve the casting method used to carry out basic cost estimation, so as to clarify the casting method that has high economic benefits and can ensure the casting regulations.
The technical standards for precision casting stainless steel plates will be introduced here in detail for everyone today.
