What is precision sheet metal fabrication?

Precision sheet metal fabrication refers to manufacturing processes that use the same fundamental methods as standard sheet metal work but with tighter tolerances and higher dimensional accuracy. It requires careful consideration of material properties, stretch behavior, and grain direction to achieve precise forming results.

To meet precision requirements, design engineers often perform detailed analysis including material behavior evaluation, forming calculations, and stress control. This ensures components achieve consistent accuracy, improved fit, and reliable performance in demanding applications.

Our Sheet Metal Fabrication Capabilities

Sheet metal fabrication is a versatile process that offers fast production speed, cost efficiency, and good dimensional accuracy for both prototypes and production parts. It allows quick design changes and flexible manufacturing, making it suitable for customized applications.

At higher volumes, sheet metal parts become more cost-effective while maintaining stable quality and repeatability. The process supports a wide range of materials and enables components for demanding environments requiring strength, heat resistance, and corrosion protection.

Cutting types - without shear

Several processes including extreme heat, vaporization, and high pressure abrasive blasting, make it possible to cut through sheet metal without shear.

Laser Cutting

Laser cutting uses a high-powered laser beam to melt and vaporize material from sheet metal with high precision. A CO₂ laser is commonly used, delivering a focused beam as fine as 0.15–0.41 mm for clean and accurate cuts. Assist gases such as oxygen or nitrogen are used to improve cutting efficiency and edge quality.

Plasma Cutting

Plasma cutting uses ionized gas (plasma) to cut electrically conductive metals. It is ideal for thicker materials but produces a rougher edge with burrs and oxidation zones. The process is fast and efficient but less precise compared to laser cutting.

Water Jet Cutting

Water jet cutting uses a high-pressure stream of water mixed with abrasives at up to 60,000 psi to erode material without heat. It produces no heat distortion or burrs and delivers excellent surface finish, but it is slower and has a wider kerf than laser cutting.

Cutting types - with shear

Shearing

Shearing is a straight-line cutting process used to separate sheet metal into two parts using a shear force. The sheet is supported by a die while a punch applies force to cut through the material, leaving a controlled edge with a small clearance typically 5–10% of material thickness.

The cutting edge includes a characteristic profile with a rollover zone, burnished surface, and fractured region. This process is ideal for high-volume straight cuts in softer materials, though burrs may form and finishing may be required.

Blanking and punching

Blanking and punching are similar processes where a punch forces material through a die. In blanking, the cut-out piece is the final component, while in punching, the remaining sheet is the finished part and the removed material becomes scrap.

These processes are suitable for medium to high-volume production of repeated hole or shape features. However, secondary finishing is often required to remove burrs and improve edge quality.

Sawing

Sawing uses toothed blades such as band saws or disc saws to cut through metal by creating a series of small shear actions. Each tooth removes a small chip through combined friction and shear force.

This method is ideal for large workpieces and softer metals, especially when moderate accuracy and surface finish are required. However, it can produce heavy burrs depending on material and tool condition.

Types of Sheet Metal Fabrication Processes

At Junvor, we provide comprehensive sheet metal fabrication services in China, supporting everything from prototype development to high-volume production. Our experienced engineering team ensures every part is manufactured with precise specifications, consistent quality, and reliable performance.

Laser Cutting

Laser cutting provides high precision and clean edges for complex sheet metal parts. It ensures fast cutting speed, minimal material waste, and excellent accuracy for stainless steel, aluminum, and other metals.

Bending

Sheet metal bending uses advanced press brake machines to form accurate angles and consistent dimensions. It is essential for structural strength, assembly fit, and functional industrial components.

Welding

Welding is a key fabrication process used to securely join metal components. It ensures strong joints, structural integrity, and durability for a wide range of sheet metal assemblies and industrial applications.

Punching

Punching is a cost-effective sheet metal process used to create holes and complex patterns with high precision. It is ideal for high-volume production with consistent quality and efficient manufacturing speed.

Riveting

Riveting is a reliable fastening method used to join metal components without welding. It provides strong structural connections and is suitable for complex assemblies where welding is not practical.

Stamping

Stamping forms sheet metal into specific shapes using high-pressure dies. It enables efficient mass production of uniform parts and is widely used in automotive and industrial manufacturing.

Die Cutting

Die cutting is a precise sheet metal process used to produce custom-shaped parts with tight tolerances and high repeatability. It is ideal for mass production, ensuring consistent quality and efficient manufacturing performance.

Embossing

Embossing is a sheet metal forming process that uses matched male and female dies to create raised or recessed patterns. It improves surface texture and appearance while maintaining structural integrity.

Forming

Sheet metal forming shapes metal sheets through bending, stretching, and pressing. It allows complex geometries with good strength, precision, and consistent quality for industrial applications.

Key Design Considerations in Sheet Metal Fabrication

Wall thickness is one of the most critical factors in sheet metal design, as parts are formed from a single sheet and must maintain a uniform thickness. Inconsistent thickness can lead to deformation and uneven strength distribution during manufacturing.

For laser-cut and formed sheet metal parts, the recommended thickness range is typically 0.5–10 mm, while bent components perform best within 0.5–6 mm. Proper thickness control improves formability, structural stability, and overall product quality.

Kerf Allowance in Laser Cutting Design

Laser cutting removes a small amount of material during processing, known as the cutting kerf. On average, laser cutting produces a very fine kerf of around 0.3 mm, which is generally lower than waterjet or plasma cutting. However, the exact kerf may vary depending on the material type and laser beam characteristics.

When designing interlocking or assembly parts, kerf compensation is essential to ensure accurate fitting. A common engineering practice is to add half of the kerf to internal dimensions and subtract the same amount from external dimensions to achieve precise assembly tolerance.

Minimum Hole Diameter Recommendation

Holes that are smaller than the sheet thickness may cause deformation, reduced accuracy, or poor edge quality due to thermal influence and cutting kerf effects. Therefore, proper hole sizing is critical for stable laser cutting results.

As a general rule, hole diameters should be at least equal to or greater than the sheet thickness. While smaller holes can sometimes be produced, following this guideline ensures better precision and manufacturing reliability.

Proper Spacing Between Holes

When holes are placed too close together, the material may weaken or deform during cutting or subsequent forming processes due to heat concentration and structural stress.

To maintain structural integrity, it is recommended to keep a minimum distance of at least 2× the sheet thickness between holes. This spacing helps prevent distortion and ensures consistent machining quality.

Edge Distance for Hole Placement

Holes positioned too close to the edge of a component are more likely to tear, deform, or weaken the structure, especially under bending or mechanical stress.

To improve durability and manufacturing stability, all holes should be placed at least one sheet thickness away from the edge. This reduces the risk of edge failure and improves overall part strength.

Hole Positioning Near Bend Areas

Holes located too close to bend lines may become distorted during forming or act as unintended relief cuts, affecting part accuracy and structural integrity.

To avoid such issues, ensure all holes are positioned at least 2× the sheet thickness away from the start of any bend radius. This ensures stable forming performance and consistent dimensional accuracy.
