Plasma cutting from independent machine shops

An ionized gas arc cuts conductive metal plate fast and cheaply, the best value on medium-to-thick steel, stainless, and aluminum. Upload a drawing and hear back from shops set up for plasma profile cutting.

How it works

How OpenSpindle Works

1

Upload your files

Share your CAD files or drawings (STEP, DXF, DWG, PDF) and note material, tolerances, and quantity. It takes a couple of minutes.

2

Get matched quotes

We route your part to shops with the machines and materials to make it, and they send competitive quotes.

3

Compare and choose

Weigh quotes, methods, and lead times side by side, then pick the shop that fits your budget and timeline.

Plate our plasma shops cut

Plasma cuts electrically conductive metals only. Common plate is below; it cannot cut plastics, wood, glass, or composites, which need laser or waterjet.

Specs

Tolerances you can expect

Profile (conventional plasma)±0.03 inShop standard
Profile (HD plasma)±0.01 inShop standard
Cut edge squareness2-5° bevel typicalAs-cut
Hole diameter±0.02 inAs-cut, drill for tighter

Plasma runs looser than laser or waterjet. Expect a heat-affected zone and a slight edge bevel; high-definition (HD) plasma tightens both. If you need laser-grade edges or a square wall, call it out and shops will quote the right process.

Getting a quote that comes back fast

Instead ofSend this
"Cut this plate, need a quote""A36 steel, 1/2 in plate, profile per DXF, qty 25"
"Some holes in it""⌀0.53 holes, ±0.02, drill if plasma cannot hold it"
"Clean edges""HD plasma or laser edge on the visible face, dross removed"

Send a flat DXF or DWG with material and thickness. Say where the edge shows and whether holes are drilled or plasma-cut; that sets the process and the price.

Applications

Designing for this process

What actually changes your quote

Not a definition of plasma cutting. The design choices that move your price and lead time.

Thickness picks the process

Under about 1/8 in, laser gives a better edge for similar money. From 1/4 in up, plasma is faster and cheaper than laser or waterjet. Match the process to your plate.

Small holes fight the arc

Plasma struggles to hold round holes smaller than about 1.5x the plate thickness. Size holes generously, or plan to drill the tight ones as a secondary op.

Leave stock for a machined edge

The cut edge has a heat-affected zone and a slight bevel. If a face gets machined or bolted flat, leave a little stock so the shop can clean it up.

Nest to cut scrap cost

Plasma is priced on cut length and plate used. Simple outlines that nest tightly on standard plate cut cheaper than parts that waste material between them.

Questions

Frequently asked questions

Plasma is the cheapest, fastest way to profile-cut medium-to-thick conductive plate, roughly 1/4 in and up. Laser gives a cleaner, more precise edge on thinner material; waterjet holds tight tolerances with no heat but runs slower and costs more on thick steel. For structural steel blanks and weldment parts, plasma usually wins on price.
