Sand casting is a time-honored and widely used metal forming process. It involves pouring molten metal into a mold made of sand, where it solidifies to form a metal casting with the desired shape and dimensions. This process is suitable for various metal materials such as cast iron, cast steel, aluminum alloys, and copper alloys, enabling the production of castings ranging from a few grams to tens of tons in weight.
Due to its high flexibility, low cost, and strong adaptability, sand casting is extensively applied in industries such as automotive, machinery manufacturing, energy equipment, rail transportation, and agricultural machinery. It has become one of the most essential processes in modern industrial manufacturing.
Product Features
Suitable for the production of various metal materials and complex-shaped castings.
Compared with other casting methods, the mold cost of sand casting is relatively low, making it ideal for small to medium batch production.
Capable of producing products in a wide range of sizes, from precision small parts to large heavy-duty castings.
Mature technology with standardized process flow and strong quality control.
Flexible post-processing options including shot blasting, polishing, machining, and heat treatment according to customer requirements.
Environmentally friendly binders such as resin sand and sodium silicate sand are used to reduce pollution emissions, aligning with green casting development trends.
Typical Applications
Automotive Parts: Engine blocks, transmission housings, brake discs, etc.
Construction Machinery: Pump valve housings, hydraulic components, chassis structural parts, etc.
Railway Transportation: Bogie frames, brake components for rail vehicles, etc.
Energy Equipment: Valves, pipe fittings, wind power generator bases, etc.
Agricultural Machinery: Tractor casings, agricultural gearboxes, etc.
Brief Process Flow
Pattern Design & Manufacturing
Wood or metal patterns are made based on drawings
Molding & Core Making
Manual or machine-based production of sand molds and cores
Mold Closing & Pouring
Molten metal is poured into the mold cavity
Cooling & Shakeout
Castings are removed after cooling and sand is cleaned off
Cleaning & Grinding
