‌Casting and ‌Die casting are both commonly used processes in metal processing.

There are some obvious differences between them:

‌Scope of application‌:

Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, and is the most widely used of various casting processes. ‌

Casting is more suitable for parts with larger sizes, simple shapes, and less high precision requirements, or small batch production and single piece production. ‌

‌Product characteristics‌:

The surface of die casting is smoother and has higher dimensional consistency.

The casted products may be relatively simple, and the precision and surface quality requirements are not as high as those of die casting.

‌Cost and efficiency‌:

The die casting process requires high casting equipment and mold costs, so it is generally only used for batch manufacturing of large quantities of products. The unit cost increment is very low, and products with consistent shapes can be produced quickly and efficiently.

Casting requires the preparation of sand molds or gypsum molds, and the production cycle is relatively long, but the initial investment is low and it is relatively easier to carry out.

‌Pros and cons comparison‌:

The advantage of die casting is that it can efficiently produce a large number of small and medium-sized castings with consistent shapes, high precision and high surface quality. The disadvantage is that the initial investment cost is high and special molds need to be developed. ‌

The advantage of casting is that it is suitable for the production of large-sized, simple-shaped parts, as well as small batch or single-piece production, with low initial investment. The disadvantages are long production cycles and relatively low precision and surface quality. ‌

In summary, casting and die casting have obvious differences in terms of application scope, product characteristics, cost and efficiency, and advantages and disadvantages. Which process to choose depends on specific production needs, product design and budget considerations.
