Guangdong carbon steel castingTechnical casting requirements

For example, in sand casting, large-scale production factories should create conditions to choose advanced modeling and core-making methods. The production rate of the old-style shock or shock molding machine production line is not high enough, the labor intensity of the workers is high, the noise is loud, and they are not used to the requirements of mass production, so they should be gradually reformed. For small castings, the production line of boxless high-pressure moulding machines that can be used for horizontal or vertical parting, the production efficiency of solid moulding is high, and the area is small; for middle parts, various boxed high-pressure moulding machine production lines can be used , Air-punch molding line, in accordance with the requirements of fast and high-precision molding production line, core-making methods can be selected: cold core box, hot core box, shell core and other high-efficiency core-making methods.

Medium-volume large castings can consider using resin self-setting sand for molding and core making.

Heavy-duty produced in small batchesGuangdong Stainless Steel CastingCraftsmanship is still an important method. Craftsmanship is more sensitive to various complex requirements and does not require a lot of crafting equipment. Can use sodium silicate sand mold, VRH method sodium silicate sand mold, organic ester sodium silicate self-hardening sand mold, clay dry, resin self-hardening sand mold and cement sand mold, etc.; for heavy castings produced in a single piece, the cost of using the pit molding method is low, and it is put into production quick. Multi-box modeling and split-box modeling are more suitable for mass-produced or long-term shaped products. Although the initial investment in molds and sand boxes is high, it can be compensated by saving modeling man-hours and improving product quality.

Low pressure casting, die casting, centrifugal casting and other casting methods are only suitable for mass production due to the high prices of equipment and molds.

Conditions and methods should be appropriate

For example, it also produces large-scale machine bed and other castings. Generally, the core assembly method is used instead of the pattern and sand box, and the core is assembled in the pit; while in other factories, the sand box method is used to manufacture the pattern. Different production conditions of enterprises (including equipment, places, staff quality, etc.),Coffee machine accessoriesProduction habits and accumulated experiences are different. What products should be considered appropriate and what products are inappropriate (or unsuitable) should be considered based on these conditions.
