Arinta Engineering – Custom Metal Fabrication and Prototyping

Arinta Engineering is a Wisconsin-based metal fabrication shop specializing in custom, small-batch manufacturing with fast turnaround and precision craftsmanship. We work with startups, inventors, and businesses who need low-quantity, high-quality parts that larger shops often won’t take on.

Our in-house capabilities include:

• CNC plasma cutting (steel, stainless, aluminum)
• CNC press brake forming
• TIG and MIG welding
• 3D printing for prototyping
• Light mechanical assembly and custom jigs/fixtures

Whether you need a prototype, a custom bracket, or a short run of parts, we deliver fast, reliable service with direct communication throughout the process. We accept customer-supplied drawings or can assist with design as needed.

Located in Southeast Wisconsin, we serve clients across the U.S. and ship nationwide.

If you're looking for a flexible, responsive fabrication partner with the capabilities of a larger shop and the personal attention of a small team — let's talk.
