Die casting can produce metal parts with complex shapes, clear outlines and thin walls. Since the molten metal maintains high fluidity at an elegant high speed, it is possible to obtain metal parts that are difficult to process by other processes.
Die castings require high dimensional accuracy and require a small amount of machining to be assembled. Some die castings can be assembled directly. Its material utilization rate is about 60%--80%, and the blank utilization rate is as high as 90%.
Die casting production efficiency is high. Due to the high-speed filling, the filling time is short, the metal industry solidifies rapidly, and the die-casting operation cycle speed is fast. The die casting method has the highest productivity in various casting processes and is suitable for mass production.
Easy to use inserts. It is easy to set a positioning mechanism on the die-casting mold to facilitate the inlaying of the insert and meet the special performance requirements of the die-casting part.
Various problems encountered in die casting production technology, such as the selection of parting surface, the opening of the gate, the arrangement of the ejection, the mastery of the shrinkage law, the guarantee of precision, the type of defects and the degree thereof, etc. The technical merits of the die-cast parts themselves are premised.
