Various Techniques in Sheet Metal Fabrication ​

Cutting ​

• Laser Cutting

  Laser sheet metal fabrication or laser cutting utilizes a high-power density laser beam to cut metal materials into desired shapes. This precise method is widely used across various industries for its accuracy and efficiency in producing complex and intricate designs.

• Waterjet Cutting

  Waterjet cutting employs high-pressure water jets, often mixed with abrasives, to cut through metal sheets. It's particularly effective for cutting low-melting-point metals without causing thermal distortion.

• Plasma Cutting

  Plasma cutting involves creating an electrical pathway using ionized gas to produce a jet of hot plasma capable of penetrating thick-gauge sheet metal. Known for its cost-effectiveness, this method is ideal for rapid and efficient cutting of thicker materials.

Bending ​

The sheet metal bending process uses a wedge-shaped tool (die) to apply pressure on a sheet of metal, pushing it into a V-shaped opening to achieve the desired angle. This method is essential for forming enclosures, frames, and other components requiring specific angles or curves.

Stamping ​

Sheet metal stamping presses flat metal sheets (often from coils) through dies to form parts of the desired shape. This process is commonly used in mass production settings to create identical components efficiently.

Welding ​

Sheet metal welding joins heated and melted sheet metal parts together, either to increase their strength or to create a single integrated product. Techniques include spot welding, arc welding, and others, each chosen based on material type and application requirements.

Punching ​

Punching uses dies to punch holes or other shapes into metal sheets. This technique is valuable for creating both decorative designs and functional openings. By applying pressure through a die, specific shapes can be accurately removed from the metal sheet, enabling detailed customization for various applications.

Surface Treatment Services ​

Surface treatment plays a crucial role in custom sheet metal fabrication, offering both functional and aesthetic enhancements to the finished parts. Below are several surface treatment options available for sheet metal fabricated parts:

Anodizing

Anodizing enhances aluminum parts by improving their resistance to corrosion, wear, and hardness while also protecting the surface from damage.

Bead Blasting

Bead blasting creates a smooth, matte finish on parts, providing a uniform texture that is both appealing and functional.

Electroplating

Electroplating can serve multiple purposes including enhancing functionality, adding decorative finishes, or providing protection against corrosion. Common applications include chrome and nickel plating on steel automotive components.

Powder Coating

Powder coating involves applying a free-flowing, dry powder to the part's surface using electrostatic charge, followed by curing through heat or UV light to form a durable, even coating.

Polishing

Polishing generates a smooth, reflective surface on parts through mechanical friction or chemical reactions, resulting in an visually attractive and high-quality finish.

Brushing

Brushing employs abrasive belts to create distinctive lines on the material's surface, typically for decorative reasons, giving the part a unique textured appearance.

Tolerances and Standards ​

To ensure the manufacturability of parts and the precision of prototypes, our custom sheet metal fabrication services comply with the ISO 2768-M standard. We automatically break and deburr sharp edges unless specified otherwise.Proper tolerances in sheet metal work are essential for ensuring that parts fit and function correctly. Here are some common tolerances you might expect:

Bending Angle Tolerance

Typical Range: ±1 degree. This means that the angle formed during bending will not deviate more than 1 degree from the designed angle.

Cutting Edge Straightness

Typical Range: Depending on the cutting method (laser, waterjet), it generally falls between ±0.1 mm and ±0.5 mm. Laser Cutting: High precision, typically within ±0.1 mm. Waterjet Cutting: slightly larger tolerance, usually between ±0.2 mm and ±0.5 mm.

Hole Diameter Tolerance

Typical Range: Varies from ±0.1 mm to ±0.3 mm based on the hole size. Smaller holes have tighter tolerances, while larger holes may have slightly looser tolerances.

Material Thickness Tolerance

Typical Range: The actual thickness of the sheet can vary slightly from its nominal thickness. For thin sheets (under 3 mm), expect a tolerance of around ±0.1 mm. For thicker sheets (over 3 mm), this tolerance may increase to ±0.2 mm or more.

Flatness Tolerance

Typical Range: From ±0.5 mm per meter to ±2 mm per meter. This refers to how flat the surface is over a distance of one meter.

Design Considerations for Sheet Metal Fabrication ​

With years of experience in sheet metal manufacturing, Yes Prototype has summarized the key design features to consider when creating sheet metal parts:

Wall Thickness

Uniform thickness is essential for high-quality parts. Varying thicknesses can cause alignment issues and increase production time. Ensure consistent material thickness to meet specifications.

Bend Radius

Keep the internal bend radius at least equal to the material thickness to avoid warping and cracking. Consistent radii improve cost-effectiveness and structural integrity.

Bend Allowance and Deduction

Bend allowance adds extra material for flat patterns. Bend deduction removes material from flange lengths to achieve accurate flat patterns.

K-Factor

The K-Factor determines the ratio of the neutral axis to material thickness, varying by material properties. Knowing this value is crucial for precise bends.

Orientation of Holes and Slots

Holes and slots should be at least as large as the sheet metal thickness. Space them reasonably and keep away from edges. Consider additional features like flanges, notches, and fillets.

Edge Treatment

Edge treatments like hemming, debarring, or rolling enhance safety and durability. Hemming strengthens edges; deburring smooths rough edges; rolling improves appearance and strength.

Joining Methods

Choose the right joining method for structural strength. Welding creates strong joints; riveting allows disassembly; bolting offers flexibility for maintenance. Select based on application needs and material properties.
