Who We Are

In 1935, our company was founded by improving upon a metal bellows assembly being used in the aircraft industry. Since then, our capabilities have evolved to include custom engineering and manufacturing of a wide range of hydro-formed, mechanically-formed, and laser edge-welded metal bellows and bellows assemblies for a wide range of industries.

Additionally, we are a primary source to OEMs for precision metal joining (TIG welding, soldering and brazing) of valves, fittings and other components made of carbon steels, stainless steels and other exotic materials.

Our state-of-the-art facility features the latest in manufacturing technologies. By controlling all of our processes internally, Alloy Bellows is able to offer our customers the best efficiency, output and flexibility possible. Our commitment to continuous improvement led to the implementation of lean manufacturing principles resulting in additional means of meeting our customers’ increasing demands.

Mission & Vision

Our mission is to meet or exceed our customers’ needs by providing products and services of premier quality, cost-effectively and on-time.

Our vision:

Our customers, and future customers, are our #1 priority: Alloy Bellows & Precision Welding’s business is based on the belief that every customer and prospect counts! Our success is measured by increasing numbers of satisfied customers, escalating customer retention rates and increased market share. Our growth is testimony to our balanced competence in engineering, quality, production, and sales/marketing.


We are committed to product leadership:
Alloy Bellows will deliver the best product and services possible to the market on-time, all the time. Continuous, high quality rapid development of new products, services and internal infrastructure is imperative to maintaining and improving our competitive edge. We are committed to exploring the latest innovations and proactively adjusting to meet the ever changing demands of the markets we serve.

Alloy Bellows purchased Star Precision Technologies in 2016. Star has state of the art CNC technologies including new multi-axis CNC machines. Since then, Star Precision has become fully immersed in Alloy Bellows to help us create components and assemblies to compliment our bellows. This partnership gives Alloy Bellows the ability to keep all your needs in house to make us your "one stop shop"




Let’s work together.
