Before Tanax made containers it made steel for other people's machines, and it still does. Conveyor frames, machine bases, chassis and subframes, brackets, welded assemblies, staircases, platforms and racking, designed for manufacturability, welded to EN ISO 3834-2, machined, blasted, painted and delivered. Around a third of the factory's hours go to European machinery OEMs on repeat frame agreements.

How it is built

The decisions behind the numbers

Design for manufacture is part of the quote.

Tanax's engineers review a part for how it will actually be cut, formed, jigged and welded, and propose changes that take cost out without changing function. On repeat parts that also means designing and building the welding jigs, which is what makes a hand-welded assembly repeatable.

Robotic welding is applied where it pays, and only there.

The candidate list is built from the products themselves: parts common to more than one product, and parts with intermittent welds. On a recent programme fourteen parts were shortlisted from two OEM product families and the first four weldments went to fixture design. That is the method: map the parts, then build the fixtures.

Blast and paint are on the same rail.

The blasting chamber and the paint booth are rail-connected, so a large weldment moves from Sa 2.5 straight to primer without a re-handle and without flash rust between the two.

One roof, one owner of the tolerance stack.

Cut, form, weld, machine, blast, paint, measure and pack in one building means one supplier owns the tolerance stack instead of four suppliers blaming each other.

Proof

Deployments with a number in them

  1. 01

    Repeat frame agreements

    With European machinery OEMs in crushing and screening, agricultural harvesting, and trailer and vehicle equipment: the work that has kept this hall running for decades.

  2. 02

    A discharge belt conveyor

    Quoted at serial and prototype prices, galvanised and assembled, with customer-supplied components fitted, for a Swiss carbon-capture technology company.

  3. 03

    14 parts shortlisted

    From two OEM product families for robotic welding, with the first four weldments going to fixture design: the working method, not a slogan.

Scope

What the price includes, and what it does not

Included

  • Design for manufacture review
  • Jig and fixture design and build
  • Cutting, forming, welding, machining
  • Blasting and coating
  • Inspection and documentation
  • Packing

Not included

  • Raw material free-issue unless agreed
  • Third-party notified-body certification where required
  • Site erection unless quoted

FAQ

Questions procurement asks

Do you take EN 1090 EXC3 work?

EXC2 is certified. EXC3 is assessed case by case with the customer's designer.

How big can you machine?

6,200 × 3,000 × 1,600 mm on the large horizontal borer, up to 16 tonnes on the table.

Can you build our welding jigs?

Yes, that is a service in its own right, including jigs you then use in your own plant.

Do you galvanise?

Through a co-operating plant, hot-dip, coordinated by us as part of the job.

Will you do one prototype?

Yes, and we will price the serial run alongside it.

Do you certify welders?

Welders are qualified to EN ISO 9606 and the welding quality system is EN ISO 3834-2, audited.

Send us the specification. A drawing, a tender annex, or three sentences.

You will get a written review of it inside a week, whether or not you buy anything.
