Injection fine steel parts combine plastic injection molding with metal powder fusion. A fine metal powder is mixed with a binder and injected into a mold—when the part is finished the binder is removed, leaving a metal part or structure that is then sintered into its final form. injection fine steel parts is a cost-effective process, especially when producing complex or unusually shaped parts at high volumes (which helps offset the expense of making the mold).

EZLEE places an emphasis on understanding the specifications and customer quality requirements, and established a whole process quality control system, which is certified to ISO9001:2008, to cover the critical quality control on site, including the raw material, initial samples, process dimensions, mechanical character, surface treatment, packing and delivery.

Specifications:

A wide variety of metals can be processed with injection fine steel parts, including stainless steel, steel alloys, iron-nickel alloys, cobalt alloys, tungsten alloys, and ceramics. Alloys can be customized for highly specific functions—for example, nickel and cobalt concentrations in carbon steel formulas can be modified for high-temperature automotive applications.

Properties:

Because making a part with injection fine steel parts require only a single mold, the process is highly repeatable and produces parts consistent in size, shape, and strength. The process can also be easily automated for high-volume production and even higher quality. Most finishes on injection fine steel parts parts are inferior compared to standard CNC machining and require secondary processes for smoother finishes and tight tolerances.
