Our Manufacturing Services

  • Engineering & Design Consulting

    BellowsTech specializes in edge-welded bellows design and manufacturing. We provide up-front design and engineering consultation at no cost to our customers, and our expert engineering team optimizes your designs for maximum performance at the lowest cost to you.

  • Finish Processes

    We offer many finishing services, including metal heat treatment, cleaning, passivation, polishing, plating, and others. These processes allow us to achieve maximum cycle life in the smallest package while providing resistance to environmental forces and retaining a superior cosmetic appearance.

  • Metal Stamping & Forming

    Components are formed and stamped from strip metal into the desired diaphragm, disc, or shape. And we use stringent processes to ensure all diaphragms are symmetrical, round, concentric (OD/ID), and consistent, which results in the highest quality product.

  • Prototyping & Testing Services

    Prototypes or sample parts for many custom bellows assemblies can be provided for research and development prior to production.

    We offer cycle, pressure, & spring rate testing services, as well as dimensional inspection per AS9002.

  • Assembly

    We are metal bellows manufacturing experts, but we also offer high-level assembly work as a value-added service to our customers. We can fabricate mating components or use components provided by our customers to complete an assembly.

  • Machine Shop Services

    We offer CNC turning, milling, drilling, grinding, and honing processes. Materials include all types of stainless steel, nickel alloys, Titanium and exotic metals, aluminum, red metals, and many more.

  • Custom Packaging

    We offer both standard packaging and custom packaging to meet your needs or requirements. UHV packing, crates, and multi-layer protection are also available.

  • Tig Welding

    Micro and regular gas tungsten arc welding (GTAW) is used daily for component welding. This process produces a high-quality weld with no contamination. Many metals can be welded including all 300 series and AM350 stainless steels, nickel alloys like Inconel, Hastelloy, titanium, and other exotic metals.
