粉末注射成形法可以高效率地大批量生产形状复杂的产品,但也存在一些问题。例如因为使用了多量有机粘合剂,除去粘结剂时必须加热,但又不能迅速加热。要经过100小时以上才能使其气化。再如成形体中的粉末不够均匀等等。 Powder injection molding can efficiently produce mass-produced products in complex shapes, but there are also some problems. For example, because of the large amount of organic binder used, the binder must be heated to remove the binder but not rapidly heated. It takes more than 100 hours to vaporize it. Another example is the shape of the powder is not uniform and so on.
