Secondary CNC Machining

Some sheet metal parts require machined holes, threads, or precision surfaces. CNC machining can be integrated into the same workflow.

Sheet Metal Fabrication Capabilities

We support a wide range of sheet metal sizes, thicknesses, and fabrication requirements. Tolerances vary by material, geometry, and manufacturing process.

Capability Specification
Part Size Up to 1500 × 3000 mm, depending on geometry
Sheet Thickness 0.5–7 mm, depending on material and process
General Tolerance Typically ±0.1–0.5 mm
Cutting Tolerance Typically ±0.1–0.3 mm
Bending Tolerance Typically ±0.2–0.5 mm
Bend Angle Tolerance Typically ±0.5–1.5°
Production Volume Prototypes, low volume, production
Lead Time Typically 3–8 business days

From CAD File to Manufacturable Part

Our engineers review each design before production to identify potential cost, deformation, forming, and consistency issues early. You also receive responsive support and clear updates on lead times, shipping, and any other details that matter to you.

1
DFM & Cost Review
We review material, thickness, bend features, tolerances, forming, and welding requirements to identify manufacturability risks and cost drivers before production.
2
Prototype or First Article
Prototypes or first articles help validate part fit, forming, appearance, and manufacturability before full production.
3
Production
Production follows approved drawings, specifications, and inspection requirements, with controlled processes and drawing versions for repeat orders.
4
Inspection & Delivery
Once production and inspection are complete, parts are finished, assembled when required, packaged, and prepared for delivery.

Sheet Metal Materials We Fabricate

Material choice drives formability, strength, corrosion resistance and cost. FastPreci supports a range of commonly used sheet metals for industrial and engineering applications.

Aluminum Sheet Metal

  • Commonly: 5052; 6061; 6063
  • Enclosures, brackets, panels and lightweight structures where weight and corrosion resistance matter.
  • Commonly: 304; 316L; 430
  • Medical and food equipment, and parts that need corrosion resistance with a surface that can be cleaned.
  • Commonly: A36; 1018
  • Frames, brackets and structural parts, usually finished for corrosion protection.
  • Galvanized sheet provides improved corrosion resistance and is commonly used for equipment housings, panels, brackets, and industrial components.
  • Copper and brass can be fabricated for electrical, thermal, decorative, and specialized engineering applications.

Available Sheet Metal Finishing

Fabrication is only one part of the finished component. Surface finishing can improve corrosion resistance, wear resistance, appearance, conductivity, or identification.

Black Matte powder coated part scaled

Powder Coating

Provides a durable colored coating for equipment housings, brackets, frames, panels, and other industrial components.

Anodized aluminum samples showing blue, green, purple, gold, orange, red, clear, and black finishes

Anodizing

Commonly used for aluminum parts to improve surface appearance and corrosion resistance.

Brushed aluminum with straight grain pattern and clear anodize

Brushing

Creates a directional surface texture and is often used for visible stainless steel or aluminum components.

aluminum part with Sandblasted Black Oxidized Finish

Bead Blasting

Creates a uniform surface texture and can be used as a preparation step before coating or as a final appearance.

Polished CNC Stainless Steel Parts

Polishing

Provides a smoother and more reflective surface where appearance or surface requirements call for it.

Laser Engraving on Metal housing with FastPreci Logo

Laser Marking

Used for logos, part numbers, serial numbers, labels, and other identification requirements.

Passivation of Stainless Steel Parts After Machining

Passivation

Commonly applied to stainless steel to improve corrosion resistance after machining or fabrication.

CNC machined tellurium copper part with nickel plating finish

Plating

Used where additional corrosion resistance, wear resistance, conductivity, or appearance is required.

Quality Control That Holds Up in Production

Production quality needs to remain consistent from the first article through recurring orders. Our quality controls follow a documented quality assurance process from drawing to delivery:

1
Incoming Material Inspection Material is checked against the project requirements before production, including material type, thickness, and relevant documentation where required.
2
First Article Inspection The first completed parts are checked against the drawings and agreed requirements before continuing full production.
3
In-Process Inspection Critical dimensions, bend angles, hole locations, and other important features can be checked during fabrication to catch problems before they affect a larger batch.
4
Final Inspection Finished parts are inspected against the required dimensions, tolerances, surface finish, appearance, and other specified requirements.
5
Inspection Documentation Inspection reports and relevant quality documentation can be provided according to project requirements.

Standard features are measured with calipers, micrometers and height gauges. Critical features are checked on the CMM. Inspection records are available when the project requires them.
