Notes from the shop floor

Design rules, material picks and cost drivers — written by the people who cut, bend and weld your parts. No fluff, one note at a time.

Laser-cut 3 mm mild steel parts with the problem spots circled in red marker FEATURED
Design for MFG Jun 24, 2026 · 6 min read

The three design rules behind 90% of rejected DXFs

Tiny holes, features hugging the edge, and "sharp" inner corners — why the physics says no, what the beam actually does, and the one-line fixes that keep your quote from bouncing back.

Design for MFG Jul 2, 2026

From CAD file to coated part: the five stations a job travels

One file, one supplier, one PO — follow a bracket from the drawing you email us to the finished part on your dock, station by station.

A stainless trolley: laser-perforated, folded shelves on a welded frame N-15 · ROOF
Insights Jul 4, 2026

Why one job shop beats five suppliers

Every handoff is a lead time, a markup and a place for the blame to hide. The case for one supplier who cuts, bends and welds in-house and handles the coating.

Laser-perforated stainless sheets on a pallet, the protective film half peeled N-29 · TOLERANCE
Design for MFG Aug 21, 2026

Kerf and cut tolerance: how accurate a laser really is

The beam has a width and the cut edge is not a perfect line. What kerf is, why the machine compensates for you, the tolerance a fiber laser holds, and where the last tenth of a millimetre starts to matter.

What powder coating costs

Priced by area, not weight — the five things that move the number, and the batching and colour choices that make the same part cheaper to coat.

What a sheet-metal part actually costs

No job shop can publish a price list. So here is the model instead: the five things you pay for, our own material index, and one real part worked all the way through.

A scrap bin heaped with rejected bent brackets: wrong angles, cracked bends, warped flanges N-16 · COST
Insights Jun 26, 2026

The real cost of a "cheap" quote

The lowest number on the page is not the price you pay. Rework, rejects and the DFM nobody did all land on the same invoice — later.

Prototype to production: what changes between 1 and 1,000

The one you approved was hand-finished. The thousandth can’t be. What scales, what doesn’t, and how to design for the run.

Sheet metal vs machining vs casting: choosing the process

Four pallets of bent stainless U-channels, stacked and ready to ship N-20 · BEND
Design for MFG Jun 28, 2026

Bend design rules: minimum flange, relief and hole-to-bend distance

The press brake needs room to work and the metal needs room to move. Three geometry rules that keep a folded part from cracking or distorting.

A TIG-welded stainless frame of square tube on a pallet, a weld at every corner N-21 · WELD
Design for MFG Jun 14, 2026

Weld joint design: gaps, access and fit-up for a clean seam

A weld is only as good as the joint it’s laid in. Design the gap, the access and the fit-up so the torch can do its job.

Designing for powder coat: drain holes, hanging points and recesses

A part that’s easy to cut can be a nightmare to coat. Four things to design in so the finish goes on evenly and the pretreatment drains away.

A clinch nut pressed into a panel N-23 · FIX
Design for MFG Apr 24, 2026

Hardware in sheet: clinch nuts, countersinks and tapped vs clearance holes

Thin sheet has almost no thread to grip. How to put a strong, reusable fastener into it — and when a tapped hole is a trap.

Anatomy of a nest: fitting your parts on a sheet to cut cost

Half the price of a laser-cut part is the sheet it sits on. How a good nest packs parts, shares cut lines and batches jobs.

Bent stainless tubes on a pallet: U-bends, elbows and long curves N-26 · TUBE
Design for MFG Apr 12, 2026

Tube bending, step by step: from straight stick to finished part

A bent tube looks simple and hides a lot of craft. Clamp, draw, and the springback we cancel so your angle lands.

Two welded stainless table frames standing side by side N-27 · BUILD
Design for MFG Mar 28, 2026

A weldment from flat: cut, bend, fixture, weld, dress, coat

A welded frame is a sequence, and the order matters as much as the welds. Why the fixture is built before the arc strikes.

O₂ vs N₂: what assist gas does to your edge — and your invoice
