注射成形不同于常规粉末冶金工艺,所采用的粉末要细得多,典型的粉末粒度是10μm或更小,且要使用大量的热塑性粘结剂以便注射成形,并在注射成形模中施加低而均匀的等静压力。
Injection molding differs from conventional powder metallurgy processes in the much finer powders used, typical particle sizes of 10 μm or less, and the use of large amounts of thermoplastic binder for injection molding and low application in injection molding Homogeneous isostatic pressure.
