Tolerances for Sheet Metal Fabrication

Tolerance Type	Typical Tolerance	Manufacturing Considerations
Linear Dimensions	±0.20 mm	Suitable for standard laser-cut and punched features
Hole Diameter	±0.10 mm	Tighter holes may require drilling or reaming
Hole Position	±0.15 mm	Depends on datum control and sheet stability
Bend Angle	±0.5°	Influenced by material thickness and springback
Bend Location	±0.30 mm	Multiple bends may increase accumulated variation

Available Materials for Sheet Metal Fabrication

. Metal .
- Aluminum Alloys
  
  Lightweight, corrosion-resistant, and easy to form. Aluminum is suitable for components requiring good strength with reduced weight.
  
  Typical Applications
  
  Cost Efficiency:
- Stainless Steel
  
  Strong, corrosion-resistant, and suitable for demanding indoor and outdoor environments. Stainless steel also provides a clean, professional appearance.
  
  Cost Efficiency:
- Carbon Steel
  
  Cost-effective, strong, and easy to cut, bend, and weld. Carbon steel is commonly used for structural and general industrial components.
  
  Cost Efficiency:
- Galvanized Steel
  
  Galvanized steel features a protective zinc coating that improves corrosion resistance while maintaining good forming and fabrication performance.
  
  Cost Efficiency:
- Brass
  
  Brass offers good corrosion resistance, conductivity, formability, and decorative appearance. It is suitable for both functional and visible components.

Surface Finishing Options

We offer a variety of surface finishing options to enhance the appearance, durability, and performance of your CNC machined parts.

Sandblasting

High-speed abrasive particles remove oxidation, dirt, and minor machining marks while creating a clean, uniform matte texture.
Anodizing

Anodizing forms a protective oxide layer on aluminum surfaces, improving corrosion resistance, surface hardness, and appearance. Clear, black, and custom colors are available.
Hard Anodizing

Hard anodizing creates a thicker and more wear-resistant oxide layer than standard anodizing. It is suitable for components exposed to friction and demanding operating conditions.
Powder Coating

Powder coating applies a durable dry-powder layer that is cured under heat. It provides strong resistance to corrosion, impact, scratching, and outdoor exposure.
Electroplating

Electroplating deposits a thin metallic layer onto the part surface to improve corrosion resistance, conductivity, wear performance, or decorative appearance.
Electroless Nickel Plating

Electroless nickel plating produces a uniform coating across complex shapes, holes, and recessed areas. It improves corrosion resistance, hardness, and dimensional consistency.
Passivation

Passivation removes free iron and surface contaminants from stainless steel while strengthening its natural corrosion-resistant oxide layer.
Brushing

Brushing creates a consistent directional grain on metal surfaces. It improves appearance while helping conceal minor scratches and fabrication marks.
Polishing

Polishing smooths the metal surface to create a brighter, cleaner, and more reflective finish. Different gloss levels can be achieved according to project requirements.
