Why Redstone

Quality, cost, and a clear fit

Redstone helps hardware teams move from released drawings to repeat production with documented quality, competitive unit costs, and engineering support from the U.S.

  • ISO 9001 certified facilities
  • U.S.-based engineering support
  • Direct manufacturing partner
Quality

Cut to print, inspected before it ships

Every plasma-cut part runs to ISO 9001 with dimensional inspection against your drawing before it leaves the floor. Seattle engineering reviews each program for cut-path and tolerance, and each shipment carries the documentation a customer quality audit expects.

  • ISO 9001 certified facilities
  • Dimensional inspection on every part
  • Seattle engineering oversight on every program
  • Certificate of Conformance with every shipment
Cost

Cost-effective on heavy plate

Plasma cutting has no hard tooling, so cost is driven by material, thickness, cut complexity, and order quantity. On heavy plate above half an inch it runs faster and at lower cost per inch than most alternatives. We quote on landed cost, with freight and duties in the number before you see it.

  • No hard tooling cost
  • Efficient on plate above 0.5"
  • Freight and duties quoted up front
  • Quick changeover keeps small and large runs affordable
Fit

Is this a fit?

Plasma cutting suits conductive metals in sheet through heavy plate where speed on thicker stock matters more than the finest edge. If you are cutting structural steel, aluminum, or stainless from released drawings, this is the lane. For tighter tolerances on thinner gauge, laser is often the better match, and our team will recommend it.

  • Structural steel, aluminum, and stainless
  • Thin gauge sheet through heavy plate
  • Prototype through high-volume recurring runs
  • Flat-profile parts from released drawings

From quote to production

A five-step process, documented at every handoff

From initial drawings to final delivery, Redstone keeps each stage clear, documented, and aligned with production requirements.

Each handoff is documented. No stage moves forward until drawings, materials, and production requirements are confirmed with the customer.

  1. 01

    Submit Your Drawings

    Upload your 2D DXF or compatible CAD files. Our engineering team reviews every submission for cut-path optimization, tolerance requirements, and manufacturability before quoting.

  2. 02

    Material Selection

    We confirm the alloy, grade, and thickness for your project and recommend plasma or an alternative cutting method based on your part geometry and edge requirements.

  3. 03

    Programming

    Your parts are programmed for precision positioning, with cut paths set for optimal material yield. First-article cuts are reviewed before any full production release.

  4. 04

    Production Cutting

    The plasma cutter runs your parts under controlled speed and airflow, with in-process checks on dimensional accuracy across the run.

  5. 05

    Inspection, Finishing, and Delivery

    Each part undergoes dimensional inspection. Secondary operations such as deburring, powder coating, and spot joining are available on request. We are the importer of record and coordinate freight to your dock with a Certificate of Conformance.

Frequently asked questions

Don’t see your question? Request a quote and our engineering team will answer it.

What is the difference between plasma and laser cutting?

Plasma uses a jet of ionized gas to cut conductive metals, while laser uses a focused light beam. Plasma is faster and more cost-effective on thick stock above half an inch. Laser delivers tighter tolerances and a finer edge on thinner sheet metal. Redstone offers both, so our team can match the right method to your project at the feasibility review.

What metals can be plasma cut?

Any metal that conducts electricity can be plasma cut, including mild steel, stainless, aluminum, copper, and brass. The workpiece must conduct current for the arc to form, so non-metallic materials require alternative methods such as waterjet cutting.

How thick can a CNC plasma cutter handle?

Achievable thickness depends on the alloy and equipment. As a guide, our facilities cover carbon steel and chromoly up to about 2", stainless up to about 1.5", and aluminum up to about 1". Heavier plate or tight tolerances on critical dimensions are reviewed against your drawing at the feasibility review.

What is plasma cutting and why use it?

Plasma cutting is a thermal process that uses a high-velocity jet of ionized gas to slice through conductive metals. Because there is no hard tooling, it moves from prototype to production on the same setup, cuts thick plate quickly, and suits both one-off parts and recurring runs. It is well matched to structural brackets, frames, and heavy flat hardware developed from a CAD file.

What file formats do you accept?

Send a 2D DXF or compatible CAD drawing for the cut profile. Include the material type, thickness, quantity, and any finishing requirements. Our engineering team reviews cut path, tolerance, and minimum feature size against the material before quoting.

What secondary operations are available?

After cutting we can arrange deburring, powder coating, spot joining, welding, bending, and assembly. Parts can be delivered as cut blanks or as finished sub-assemblies depending on your program requirements.

What are your standard lead times?

Standard production lead time is 4 to 8 weeks, with first-article and full production timing confirmed at the quote stage. Rush programs can be reviewed case by case.
