Proto Labs Introduces Low-Alloy Steel to Metal Injection Molding

New low-alloy steel options complement existing stainless steel materials for injection molding

MAPLE PLAIN, Minn.--Product designers and engineers can now get injection-molded low-alloy steel prototypes and low-volume production parts at rapid manufacturer Proto Labs, Inc. (NYSE: PRLB). The technology-driven company has added two nickel steel materials (Catamold FN02 and FN0205) and a chrome-moly material (Catamold 42CrMo4) that is the metal injection molding (MIM) equivalent of 4140 steel. The new metals expand the potential applications for parts produced by Proto Labs' advanced MIM process.


"We've 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, Proto Labs' product manager for MIM. "We offer many different hard and soft metals through our 3D printing and CNC machining services at Proto Labs, but nickel steel is only produced through metal injection molding. This material boost will inherently let our customers do more things in the realm of low-volume metal manufacturing."

Low-alloy steel creates strong, wear-resistant metal parts when heat-treated and is able to be to be coated in post-processing for further protection. 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, and the industrial goods sector 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 5,000+ metal injection molded end-use parts within 15 days. Learn more about the complex multistep MIM process with a comprehensive white paper at protolabs.com.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
