What Are Different Types of Metalworking Tools?

Sand mold casting has low cost, small batch size, and can process complex shapes, but may require a large number of post-processing steps. Investment casting lost wax casting has a high degree of continuity and accuracy, and it can also be used to process complex shapes. It can achieve a very perfect surface effect under the premise of relatively low processing costs, which is suitable for mass production. Injection molding is used to process complex shapes with high errors. Due to the characteristics of the process itself, no post-processing is required after the product is shaped, however, only in the case of mass production can it show the advantage of low cost. Die-casting has high processing costs, and the cost is reasonable only in the case of mass production. But the cost of the final product is relatively low and the error is high. Can be used to produce thin wall parts. Spin casting is the ideal method for processing small parts, and is often used in jewelry manufacturing. Eraser models can be used to reduce processing costs.
