What are the disadvantages of die casting process?

The biggest disadvantage of die casting is its high cost. Compared with other casting methods, casting equipment, molds and parts related to molds are expensive. Therefore, it is more economical to produce a large number of products when manufacturing die castings. Other disadvantages include: this process is only suitable for metals with high fluidity, and the casting quality must be between 30g and10kg. Normal die casting, the last batch of castings will always have pores. Therefore, no heat treatment or welding can be carried out, because the gas in the gap will expand under the action of heat, resulting in internal micro-defects and surface peeling.
