The difference between coated sand shell mold casting and Disa line sand casting
In the casting industry, shell molding and Disa line sand casting are two common casting techniques widely used in the production of various Metal Castings. Although both belong to the sand casting process, they differ significantly in their processes, applications, and pros and cons. Understanding these differences can help companies choose the most suitable casting technology, thereby enhancing production efficiency and product quality.
The main difference between coated sand shell mold casting and Disa line sand casting
| feature | Coated sand shell mold casting | Disa line is sand cast |
| technical principle | A thin film shell is coated to form a casting mold, which is suitable for complex-shaped castings. | Sand molds are formed by the Disa line machine (sand mold forming machine), which is suitable for mass production. |
| surface finish quality | The surface finish is high, suitable for castings with high precision requirements. | The surface finish is relatively low and suitable for ordinary castings in mass production. |
| Accuracy of casting | The accuracy is higher, and the more stringent size requirements can be achieved. | The accuracy is low, suitable for castings with low accuracy requirements. |
| Applicable materials | It is usually suitable for high-strength, high-temperature alloys, cast iron, and other materials. | It is often used for cast steel, cast iron, and other materials, suitable for mass production. |
| production efficiency | The production cycle is long, suitable for small batch or Precision Casting production. | High production efficiency, suitable for mass production. |
| prime cost | The cost is high, suitable for high-end or customized castings. | Low cost, suitable for the production of conventional products. |
| Mold strength | The coated sand shell mold is more robust and suitable for complex and high-requirement castings. | The sand mold of Disa line is of low strength and suitable for conventional castings. |
