Proto Labs, Maple Plain, Minn., has added two nickel-steel alloys and a chrome-moly steel that is the metal injection molding equivalent of 4140 steel to its portfolio of MIM materials. They expand potential applications for parts produced by its advanced MIM process. Low-alloy steels enable strong wear-resistant parts when heat-treated, and may also be coated in post-processing for further protection.
“We had tremendous customer demand for stainless steel with MIM last year, and expect the same response to our new low-alloy metals,” says Becky Cater, product manager for MIM. “We offer many different hard and soft metals through our 3D printing and CNC machining services, but nickel steel parts are only produced through metal injection molding.”
As for applications, the low-alloy steel materials will be used heavily by the firearms industry for various gun and archery components, as well as by automotive engineers for engine and transmission components. The industrial goods sector will use MIM during development of hand and power tools, and door and window lock hardware, for example.
In addition to rapid prototypes, Proto Labs can produce up to 5000+ metal-injection-molded end-use parts within 15 days.
