One-Offs, Prototypes and Repeat Batches

From One-Off Prototypes to Repeat Production Batches

Kaizen Engineering makes laser cut, folded, welded and assembled parts to your drawing at our works on Thomas Street, Shaw, Oldham, in whatever quantity you need. Some customers send us a single bracket for a prototype. Others send a drawing pack for a production line and order the same parts every month. We set up both kinds of job the same way, so the part you approve at prototype stage is the part you get on every batch after it.

One-Offs and Prototypes

A first-off or prototype part is often the hardest one to get made. Many subcontractors are geared up for volume and aren’t keen on a single piece. We’re happy to quote it:

• Single parts and replacements: a bracket, guard, plate or cover to replace one that’s broken or missing
• Prototypes and first-offs: try a design before you commit to a batch, then change the drawing and go again
• Before it goes into production: if you’re unsure about a bend, a hole position or the material, ask when you send the drawing
• No drawing yet? Send a sketch, or photos of the part with the main dimensions and thickness, and we’ll tell you what we need to quote it

Batch, Repeat and Contract Work

Once a part is programmed it can be cut again and again to the same standard. That makes repeat orders simple for you and consistent from one batch to the next:

• Short batches: tens of parts for a small production run or a maintenance stock
• Repeat orders: tell us roughly how often a part repeats and we’ll quote with that in mind, so re-ordering is simple
• Volume and call-off work: we support large UK manufacturers on a just-in-time basis, with repeat and volume work
• Kits and sets: parts grouped, labelled and packed per job or kit, ready for your line
• Second source: if you already buy a part elsewhere and want a back-up supplier, send the drawing and current revision and we’ll quote it

One Supplier from Flat Sheet to Finished Assembly

Every stage happens on one site in Shaw, so parts don’t travel between subcontractors or wait in storage between operations:

1. Laser cut on our 8kW Trumpf fibre laser, in mild and stainless steel up to 25mm and aluminium up to 12mm.
2. Fold on our CNC press brake, up to 4m long and 20mm thick on our 250-tonne Bystronic.
3. Weld and fabricate with MIG and TIG in our 11,000 sq ft fabrication facility.
4. Assemble the parts into finished units or sub-assemblies to your drawing with our assembly team.

Materials in Stock

We hold a large stock of material on site, including S275 and S355 carbon steel, wear plate, and 304 and 316 stainless steel, which helps keep lead times short on one-offs and batches alike. We also keep Hardox^® wear steel in stock for wear parts; see our SSAB steels page. We make finished parts only and don’t sell sheet or plate.

Who We Work With

Larger manufacturers and OEMs

Machine builders, equipment makers and production sites that need a reliable subcontractor for repeat parts, kits and sub-assemblies, made to the same standard on every batch.

Smaller firms and one-off buyers

Small engineering firms, start-ups, designers, maintenance teams and local businesses that need a prototype, a replacement part or a short run.

One-Off and Batch Work FAQs

What should I send for a repeat order?

Send the drawing with its current revision, the quantity and the date you need the parts. If the design has changed since last time, mark up what’s new so we work to the latest version.

Can you quote several quantities at once?

Yes. Tell us the quantities you’re considering and we’ll price each, so you can choose the batch size that suits you.

Can you make a prototype and then the production run?

Yes. Many jobs start as a single first-off. Once you’ve approved it, we make the batch to the approved design, with any drawing changes made first.

Can you supply kits or finished assemblies?

Yes. We can cut, fold, weld and assemble on one site, and supply parts as loose components, kits or finished sub-assemblies.

We supply firms across Greater Manchester, Yorkshire and the UK, including Oldham, Manchester, Leeds and Sheffield.
