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, a boxless high pressure molding machine production line that can be used for horizontal or vertical clinical diagnosis can be selected. The production of solid molding is highly efficient and high, and it occupies a small area; for middle parts, various types of high pressure 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 used: cold core box, hot core box, shell core and other high-efficiency core-making methods. 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 small batch production of super-heavy castings, 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. It 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 the production of super heavy-duty castings, pits are selected The modeling method is low-cost and quick to build and put into production.
Forging methods such as low-pressure casting, aluminum die-casting, and centrifugal casting 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, the production of large and medium-sized CNC lathe bed bodies and other castings. Generally, the core assembly method is used, and the shape and sandbox are not made. Make a look.
Different companies have different production standards, production habits, and accumulated work experience. Based on this standard, consideration should be given to which products are suitable and which are not suitable. Precision regulations and costs The casting precision obtained by various forging methods is different, the initial project investment and productivity are inconsistent, and the final economic benefits are also different. Therefore, to ensure more, fast, better, and economical, it should be applied to all fields. Solve the forging method used and carry out the basic cost estimation, so as to clarify the forging method that has high economic benefits and can ensure the casting regulations.
