- Understanding the Customer's Requirements for Casting Technology Performance and Castability of the
The gravity casting process typically includes the following steps:
Confirming Customer Requirements: The first step involves understanding the customer's requirements for the performance of the castings and the castability of the required castings. This includes considerations such as the application of the castings, the choice of metal alloy material, casting dimensions, casting shapes, casting thickness, technical performance (such as tensile strength and elongation), structure, and weight.
Mold Pattern Drawing and Production: This is particularly crucial for industrial parts, as precision calculations are needed to ensure that the cast parts are of the correct size and fit seamlessly with other components. Currently, high precision can be achieved through computer-aided design and production, which allows for highly accurate modeling.
Core Production: Creating a 3D shape of the design pattern to measure the accuracy of the mold before formal casting production. Core materials may include wood, clay, or plastic. With advancements in technology, 3D printing can also be used for this purpose.
Mold Manufacturing: In gravity casting, metal molds with higher melting points are often used to create reusable metal molds.
Melting and Pouring of Metal or Alloy: The metal is melted and then poured into the mold under the influence of gravity. Traditionally, this process was done manually, but due to advancements in casting technology, this casting process is often automated, significantly increasing productivity.
Finishing and Trimming: After the castings have cooled, they are removed from the mold and undergo inspection and processing. During this process, any molding materials on the castings are removed, and rough edges and surfaces are further processed to make them smooth. Additional treatments may be required to enhance the mechanical properties and quality of the castings after this step.
