MIM/PIM Metal Powder Injection Molding

MIM is economically attractive to manufacturers—especially against parts that require machining. Machined parts require a considerable amount of labor and a lot of material is lost during the process. When parts are molded in mass quantities, MIM-type parts can offer substantial savings.

Furthermore, the more complex the part, the more cost reduction the customer can realize. Eversun produces complex net-shape parts in a variety of metals including stainless steel alloys and at lower costs than traditional wrought metal and casting processes.

Applications range from needles to hearing aids, as well as implantable, suturing, orthodontic, laparoscopic, and endoscopic devices. Typical parts weigh from 0.1 to 100 gram and are about 0.030-in. In diameter and 2.00-in. Long. Some parts are even larger.

The eversun abbreviation is intended to stress that the technology involves a special marriage of shape making (plastic injection molding) and material creating (powder metallurgy) processes.
