http://www.dk-metals.com/casting/ Sand casting has existed as a technology for thousands of years and is the preferred metal casting process for the production of shaped parts weighing from less than one pound to several thousand pounds. Due to the low tool cost, sand casting has versatility and cost-effectiveness even in small batches. Almost any part configuration made by other metal casting processes can be simplified into patterns and made into sand casting.
In sand casting, the patterns of the required final parts including the metal conveying system (doors and risers) are made of hardwood, polyurethane, metal, or foam. A bonding material containing sand to maintain the shape is piled up around the pattern. Then remove the pattern from the bonded sand, leaving a part-shaped cavity in the mold. The molten liquid metal is poured into the cavity, and then the metal solidifies. Then, the sand is removed through a sieving process. Remove other casting accessories including the metal conveying system, leaving the required parts.
The advantages of the sand casting process.
1. Design Flexibility 鈥?Parts can range in size and weight from a few millimeters to a few grams to a few meters to a few tons. The size and weight of the casting are only limited by the handling and supply of the molten metal.
2. High Complexity Shapes 鈥?Complex feature shaping no other way to produce nearly final shape parts.
3. Wide selection of materials 鈥?virtually all types of engineering alloys can be cast as long as they can be melted.
4. Low cost 鈥?Tool and equipment cost is low compared to some other metal fabrication processes. Therefore, making it one of the cheapest ways to achieve near-net-shape parts.
5. Short lead times 鈥?short lead times compared to other products, making them ideal for short-run production.
6. Clay is rich in resources and cheap.
7. Most of the used clay wet sand can be recycled and reused after proper sand treatment.
8. The cycle of making the mold is short and the work efficiency is high.
9. The mixed molding sand can be used for a long time.
10. After the sand mold is pounded, it can still tolerate a small amount of deformation without damage, which is very beneficial to drafting and core lowering.
History of the sand casting process.
1. Foundry is the basic industry of the national economy, providing casting products for downstream industries such as automobiles, construction machinery, rail transit, mechanical equipment, thermal energy engineering, and aerospace.
2. The foundry industry can be divided into sand casting, precision casting, die casting, etc. Sand casting is the basic process of casting production. It is a casting process with a long history. It can be traced back thousands of years ago. Steel, iron, and most non-ferrous alloy castings can be obtained by sand casting. Therefore, casting generally refers to sand casting. Casting; investment casting, also known as investment casting, can be traced back to 4,000 years ago. It originated in Egypt, China, and India. It is mainly used for the production of copper utensils, bells, and art, and investment casting began to be used in the 1940s. Industrial production; The die-casting process appeared relatively late. In 1838, die-casting equipment was invented to manufacture the mold for movable type printing. In 1904, the American H.H.Franklin Company first used the die-casting process to produce the connecting rod support frame on the automobile, creating the application of die-casting parts to the automobile. A precedent for the automotive industry. Since the 1970s, with the development of the lightweight trend of automobiles, the aluminum die-casting industry has shown a high-speed development trend and is more closely dependent on the automotive industry.
3. Castings have different requirements for material, size, shape complexity, dimensional accuracy, surface roughness, production batch size, etc., and the most cost-effective casting process should be used for production. Different casting processes have their own necessity. Sand casting, precision casting, die casting and other processes have their advantages and disadvantages. There is no iterative relationship with each other in the short term, and there is only a competitive relationship in the field of castings that can be applied to different processes. With the continuous enrichment of casting types, the casting process will also continue to innovate and develop.
