Disadvantages of Die Casting

1). Due to the high filling speed and unstable flow state of liquid metal in the mold cavity during die casting, the general die casting method is used. The casting is prone to gas pores and cannot undergo heat treatment;

2). For castings with complex concave surfaces, die-casting is more difficult;

3). High melting point alloys (such as copper and ferrous metals) have a lower lifespan in die-casting molds;

4). It is not suitable for small-scale production, mainly due to the high manufacturing cost of die-casting molds, high production efficiency of die-casting machines, and uneconomical small-scale production.
