Prototype Sheet Metal Fabrication

September 30, 2021

Prototype manufacturing is a customized process. We have over 60 years of experience working with these unique sheet metal fabrication programs. We tailor our solutions to your sheet metal prototype program’s specific needs. From cutting and bending to stamping and assembling, each program is unique. We manage your complete program in-house, vertically integrating all processes and technologies while maintaining a single point of contact.

We utilize robotic automation in our prototype manufacturing process for OEMs, start-ups, electric and autonomous vehicles, aerospace products, and the military. Our prototype resources allow us to produce anything from small bracketry to complete Body in White vehicles. This includes manufacturing tooling, prototype stampings, trim moldings, specialty items, and sub-assemblies with complex joining.

Our Prototype manufacturing experts work with a wide array of metals, joining advanced and exotic materials including:

  • Aluminum, including bright or pre-painted
  • Stainless steel, including polished or bright grades
  • Carbon steels
  • Boron steel
  • Dual phase steel
  • Advanced high strength steels, including martensite and TRIP
  • Inconel®
  • Waspaloy®
  • Hastelloy®
  • Titanium
  • Magnesium
  • All ferrous metals

In our sheet metal prototype business we leverage old world techniques combined with the latest computer-controlled technology to bring your visions to reality. To provide complete prototype services, our prototype manufacturing capabilities include:

  • Process engineering
  • Kirksite foundry
  • Tool machining
  • Stamping
  • Hot stamping
  • Sheet metal fabrication
  • Laser cutting
  • Assembly

This range of services allow us to provide complete sheet metal prototype programs in-house, using our experience to provide you with a high quality product. Whether you need sheet metal fabrication for parts to assemble yourself or full BIW, we can design, build, and assemble your parts.  

We also develop custom assembly work cells based on your project’s specific needs to standardize processes and ensure consistent quality through the life of your project. These efficient processes allow for the rapid execution of product and process revisions, including managing master data files, incorporating working data files, and providing updates to all process documentation.

Our Battery Enclosure Capabilities

August 31, 2021

Every program has its own set of unique requirements. For battery enclosure projects, we can help plan the entire process, from R&D to production. We specialize in a range of joining technologies, including SPR, RSW, MIG, TIG, laser welding, and adhesives, ensuring we have the expertise you need. Battery enclosures also require unique testing, such as leak testing, which is done to every battery box. We then complete a dimensional check using CMM or laser scanning. This ensures every unit you receive meets your specifications.

Our Complex Robotic Joining Methods

Robots welding metal

July 22, 2021

We employ a wide range of complex robotic joining methods based on your project’s specific needs and requirements, including resistance welding, hemming, adhesives for structure and bonding, and an onsite curing oven large enough for a completed BIW. We also specialize in flow drills and laser welding, ensuring we are able to use the best possible joining technology for your program. Utilizing both manual and robotic welding allow us to customize the manufacturing process to give you the repeatability and flexibility you need. Our three Centers of Excellence give us the capacity for large prototype joining projects as well as hybrid assembly and production programs.

Our joining technologies include:

•AC manual weld guns (RSW)

•DC manual and robotic weld guns with adaptive controls (RSW)

•Press welder for fasteners (RSW)

•Clinch press for clinch nuts or studs

•Manual and robotic welders (MIG)

•Fronius “cold metal transfer” manual and robotic welders (CMT)

•Manual welding equipment (TIG)

•Drawn arc stud welding

•Self-piercing rivets (SPR) – Henrob & Bollhoff

•Flow drill screws (FFS & FDS)

•Bonding with onsite cure oven capacity for full vehicle BIW

•Roller hemming – adhesive & antiflutter

•Laser welding

After assemblies are joined, we post machine critical features that need to be drilled in or tapped. This assortment of joining methods allows us to meet your joining needs, such as joining aluminum to steel.

We have designed and completed programs with a wide array of processes for many materials, including joining aluminum, steel, stainless steel, high nickel alloys, and titanium. We can join dissimilar metals of different thicknesses using our mixed material joining technology, ensuring we can join the materials your program requires.
