Introduction to Sand Casting Process

Sand casting is a manufacturing process that involves pouring melted metal or other substances into a mold, then waiting for cooling and solidification to ultimately form the desired shape of the part. Sand casting is a traditional production process widely used in casting technology. This article will introduce the sand casting process to help you better understand it.

The sand casting process mainly includes mold manufacturing, casting (including molding, pouring, cooling, and sand recovery), post-treatment, and quality inspection. 

Firstly, mold manufacturing is the most critical step in the entire casting process, directly affecting the quality and yield of castings. It is recommended to have experienced mold design manufacturers design and use high-precision CNC machine tools for processing, producing high-precision molds that can quickly cast castings of various shapes and sizes.

Secondly, casting is the most important step in the entire casting process. The sand casting process includes molding, melting, pouring, insulation and cooling, and sand recycling. The core process is sand molding, and the quality of the molding directly determines the quality of the product. Sand molding is divided into manual molding and automated equipment molding. In the 21st century, automated molding gradually eliminates manual molding. Automated molding can effectively improve production efficiency and enhance the quality of casting production. In the article "How to improve production efficiency in cast iron casting factories", you can learn about how casting factories can improve production efficiency. The automatic green sand casting molding machine adopts horizontal parting, fully automated production, easy to use, and saves labor.

Thirdly, post-processing is an essential step in the casting process. Including the use of various techniques such as mechanical processing, surface treatment, and heat treatment to make castings smoother, smoother, and more aesthetically pleasing. These technologies can improve the quality and durability of castings, ensuring the reliability of products.

Finally, quality inspection is a necessary step in the casting process. High precision testing instruments can be used to inspect and evaluate each casting. These tests can ensure the precise size and stable performance of castings, while also preventing quality issues with castings.
