United Metal Spinning of Kansas City

What United Metal Spinning of Kansas City does

United Metal Spinning of Kansas City is a family-owned contract metal spinning job shop founded in 1929 by Otto Klemm and Jesse Bell during the Great Depression and incorporated in Missouri in 1932. The company manufactures custom spun metal components for customers across lighting, automotive, aerospace, food and vending equipment, architectural, religious, military, jewelry, and consumer appliance sectors, with notable installations including the Vatican, U.S. Navy ships, Kansas City City Hall, Jackson County Court House, and the RLDS Temple. Pricing is quote-based and engagements range from single prototypes to production runs, with the firm positioned as a flexible B2B subcontractor.

The firm's core technology is manual and CNC-assisted metal spinning on items ranging from 1/4" to 100" in diameter, with material thickness capabilities up to .104" steel, 3/16" aluminum, and 1/8" in most red metals. It works across 13+ metal types including muntz, aerospace alloys, lead, Monel, nickel, steel, aluminum, brass, bronze, copper, stainless steel, pewter, and silver. Secondary in-house services include TIG, MIG, and spot welding, a 48" capacity punch press, and light rolling up to 16-gauge x 40", enabling the company to deliver finished or partially finished sub-assemblies rather than only spun blanks. The Klemmware bakeware sub-brand extends metal spinning expertise into a branded consumer product line in honor of co-founder Otto Klemm.

The business model is a sales-led, direct-to-customer job shop with no disclosed digital marketing, no e-commerce, and no public pricing. Customers reach the firm through direct sales relationships, industry referrals, and accumulated reputation. The company is operated by Larry Sr. and Laura Brennaman with their son Larry Jr., representing the fourth generation of family involvement, and reports a headcount of 1-10 employees. Revenue is generated project-by-project with no subscription, recurring, or licensing component, and no external funding rounds have been disclosed.
