Stamped, welded, finished, and shipped ready to install.
You can buy a stamping from one shop, send it to a weld house, ship it out for paint, and then pay somebody to put it together. Or you can send ATACO the print and take delivery of the finished assembly.
We stamp it, draw it, cut it, weld it, fasten it, finish it, and ship it. One supplier, one PO, one point of contact.
One Supplier, From Raw Coil to Finished Assembly
Every step below is run or managed by our team in Cedarburg, Wisconsin. Nothing gets brokered out to a shop we have never walked through.
01
Engineering. We review the print for manufacturability before quoting. Often we find two or three parts that could be one part, or a weld that could be a form. Those decisions come out of the cost before tooling gets cut, not after.
02
Tool and die. We design and build the tooling in house. When a die needs a change in month eighteen of a program, it is a conversation with the toolmaker who built it, not a purchase order to a vendor with a twelve-week queue.
03
Stamping and deep drawing. Presses up to 1,700 tons, beds to 72 by 180 inches, material to 0.8 inches thick, and deep drawn shells up to 16 inches deep.
04
Laser cutting and forming. 2D and 3D 5-axis laser for parts and volumes where hard tooling does not pay.
05
Welding and fastening. AWS-certified manual welding, robotic weld cells, seam welding, brazing, and fastener installation.
06
Finishing and shipping. We manage coating and plating through our finishing partners, install hardware, and ship the assembly ready to go to your line.
Assembly and Joining Services
Most fabricated metal assemblies come down to how the pieces are joined. We pick the joining method that fits the part, the volume, and the finish, not the one a single-process shop happens to own.
Robotic and Manual Welding
Robotic welding services cover production volume: our weld cells put the same bead in the same place on every part. AWS-certified welders handle manual welding for prototypes, fixtures, and joints a robot cannot reach. Seam welding closes long joints on tanks and drawn halves, and spot welding joins overlapping sheet on lighter sheet metal assemblies.
Brazing and Mechanical Joining
Manual and induction brazing join dissimilar metals and thin sections that welding would warp, with less heat going into the part. When an assembly should not see heat at all, we rivet or clinch it instead. Mechanical joints keep coatings intact and let you join parts that were finished before assembly.
Fastener Installation
We install ASTM hardware, Tox® Lock fasteners, PEM-style self-clinching inserts, and the other common fasteners your print calls out. Installing hardware here, instead of at your plant or a third shop, takes a step out of your process and ships the assembly ready to bolt into your product.
Around the joining work, we also handle press brake forming, tapping and machining, hand deburring, and part washing, so the pieces arrive at assembly ready to go together.
Build to Print, or Bring Us the Problem
Two ways to work with us, and both are fine.
You have prints. Send the model and the spec. We quote to your drawing, build the tooling, and hold your tolerances. No redesign, no argument, no attempt to talk you into our way of doing it.
You have a problem and a rough idea. Bring us the function and the constraints and let our engineers get at it before the design is frozen. We run forming simulation to prove out the draw, look for part consolidation, and cut weld inches wherever the print allows. Customers who involve us this early usually end up with fewer pieces and less labor in the finished assembly.
Either way, the same engineering team and in-house tool and die shop see the job through from first article to production, so the assemblies you receive match your print.
How We Control Quality
Stamping, deep drawing, steel fabrication, welding, and assembly all happen in our Cedarburg plant. Paint and coating go to finishing partners we have vetted, and that work stays on our PO and our quality system, so you still deal with one supplier. Nothing ships until it passes our QC checks.
We are ISO 9001:2015 certified. Inspection happens in process, at the station, not only at final. We can supply first article inspection reports, and PPAP documentation on request.
Assemblies We Build by Industry
A few of the custom metal assemblies we build, grouped by the industry they go into. Each industry page shows more of the parts we make for that market.
Lawn and Garden
Mower deck assemblies for lawn and garden OEMs: the drawn deck plus its brackets and hardware, welded, finished, and shipped as one part number.
Material Handling
Frames and welded assemblies for material handling equipment, where fit-up and weld consistency decide whether the assembly bolts in on the first try.
Commercial Food Equipment
Stainless enclosures and assemblies for commercial food equipment, built in 304 and 316 with the surface finish the application calls for.
Contract Assembly FAQs
Yes, within reason. If your program includes purchased components, castings, or hardware, we will receive them, integrate them, and ship the completed assembly.
We manage finishing as part of the program. Painting, plating, and powder coat go to finishing partners we have vetted and audited, and the work stays on our PO and our quality system.
Yes. Tell us how your line consumes the part and we will package it that way.
We run short runs and full production. Low volume usually means laser and fixture work instead of hard tooling, which keeps the entry cost down.
Yes, on request. Tell us the level you need at quote time so it is priced in rather than bolted on.
