The method of casting liquid metal into a casting cavity that is suitable for the shape of the part and allowing it to cool and solidify to obtain the part or blank is called casting. Obtaining castings by casting method is called casting parts.
Casting structure design: ensuring its working performance and mechanical performance requirements, considering the requirements of casting process and alloy casting performance on the casting structure, whether the casting structure design is reasonable or not, has a significant impact on the quality, productivity, and cost of the casting.
1. Can produce parts with complex shapes, especially blanks with complex inner cavities (such as heating)
2. Wide adaptability, commonly used metal materials in industry can be cast. A few grams to several hundred tons.
3. Wide sources of raw materials. The price is low. Scrap steel, scrap parts, chips
The shape and size of the 4 castings are very close to the parts, reducing the amount of cutting and belonging to less cutting processing.
After understanding the different classifications of casting quality, Dalian Casting can take targeted measures to ensure the quality of castings. Ensure the quality of casting raw materials. During the production process of castings, a lot of raw materials are required. Including metal furnace materials, refractory materials, as well as casting sand, molding sand binders, coatings, etc. If the raw materials for casting do not meet the standards, in the subsequent production process, it may cause defects such as porosity, shrinkage, or sand inclusion in the casting, affecting the surface aesthetics of the casting, and in severe cases, it may lead to the scrapping of the casting.
Choose a reasonable casting process. Foundry manufacturers should design castings reasonably according to the requirements of the drawings during production. Based on the structure, size, and weight of the castings, as well as the properties of the casting alloy, a suitable shape and gating system for casting production are selected to ensure that high-quality castings can be obtained.
Ensure the craftsmanship of casting design. When designing castings, foundry manufacturers need to consider the relevant knowledge of stress, solidification, and shrinkage from the aspects of casting alloy and casting process characteristics, in order to avoid or reduce the occurrence of defects such as component segregation, deformation, and cracking in castings.
