Sheet Metal Manufacturing Processes and Capabilities
We specialize in high-precision sheet metal manufacturing across various industries. From the initial stages of prototyping to mass production, our high-tech approach facilitates fast, reliable, and affordable solutions. Some of our services include laser cutting, stamping, bending, welding, and assembly, all designed to deliver the highest quality parts in the most accurate and fastest way.
Bending
With bending machines and high-end forming machines, Lever Precision shapes sheet metal into precise angles and complex shapes. This service supports a wide range of material thicknesses and provides precise bending for any design, from simple to complex.
Laser Cutting
Lever Precision involves cutting sheet metal using high-power lasers to precisely cut and produce complex patterns and tight tolerances. Laser cutting is ideal for flat designs, complex features, and minimizing material and quality waste, making it ideal for prototyping or any mass production.
Stamping
Levee Precision specializes in stamping sheet metal to form cold-formed parts. This is a high-precision process that ensures a high degree of consistency in quality during high-volume production, making it ideal for producing parts with detailed and tight tolerances.
Welding
We offer high-quality welding services, such as TIG and MIG welding, for joining sheet metal components. This method guarantees high strength and durability of joints in custom assemblies, providing the structural integrity required for complex designs and end-use applications.
Sheet Metal Fabrication Overview
Sheet metal fabrication is a manufacturing process involving the shaping and assembly of
sheet metal into specific parts or products. This process includes techniques such as
cutting, bending, stamping, and welding to manufacture components for a wide range of
industries, including automotive, aerospace, construction, and electronics. Sheet metal
fabrication offers high durability, precision, and versatility, enabling manufacturers to
easily produce complex and customized designs.
Our sheet metal fabrication process begins with selecting the appropriate type of metal,
typically steel, aluminum, or stainless steel, based on the required performance of the
final product. The sheet metal is then cut into the desired shape using tools such as laser
cutters, shears, or water jets. Subsequently, the sheet metal is bent or stamped into
specific shapes using bending machines or stamping presses. Depending on the complexity of
the design, additional processes such as welding or assembly may be performed to complete
the product. The result is a finished, precision-manufactured component ready for use in its
intended application.
Advantages of Sheet Metal Fabrication
Cost-Effective Manufacturing
Sheet metal fabrication is a cost-effective method for producing high-quality components, especially in high-volume production. It minimizes material waste and production time, reducing overall manufacturing costs.
Design Versatility
Sheet metal can be easily formed, cut, and assembled into a wide variety of designs and structures. This flexibility allows for the production of everything from simple parts to complex custom configurations.
High Strength-to-Weight Ratio
Sheet metal boasts an excellent strength-to-weight ratio, making it ideal for industries such as aerospace and automotive. It provides durability and robustness while maintaining a lightweight profile, crucial for many engineering applications.
Precision and Consistency
Advanced technologies such as laser cutting and CNC machine tools enable high precision and consistency in sheet metal fabrication. This ensures that each part meets precise specifications, reduces the likelihood of defects, and improves overall product quality.
Our Sheet Metal Material Options
Sheet Metals
At HLH, we offer a wide range of high-quality sheet metals, including steel, aluminum, stainless steel, and more, tailored to the specific requirements of your manufacturing projects.
Aluminum
Aluminum is a very durable and lightweight metal, highly valued for its corrosion resistance. Its versatility and ease of handling make it suitable for various industries such as automotive, aerospace, and construction, where strength and weight efficiency are critical.
Copper
Copper is a reddish-brown metal known for its excellent electrical conductivity, making it ideal for electrical and thermal applications. It has high ductility and corrosion resistance, although it loses its luster over time.
Brass
Brass is an alloy of copper and zinc, offering good strength, corrosion resistance, and an attractive golden appearance. It is commonly used for decorative purposes, piping, and electrical fittings.
Steel
Steel is an alloy of iron and carbon, known for its strength, durability, and versatility. It is commonly used in construction, automotive, and machinery applications. Steel can be further alloyed to improve its properties.
Stainless Steel
Stainless steel is an alloy of iron, chromium, and sometimes nickel, known for its excellent corrosion resistance and strength. Due to its durability and rust resistance, it is commonly used in food processing, medical equipment, and construction applications.
Sheet Metal Finishing Options
Bead Blast
The part surface is left with a smooth, matte appearance.
Anodize (Type II Or Type III)
Type II (MIL-A-8625/MIL-PRF-8625, Type II) creates a corrosion-resistant finish. Sheet metal parts can be anodized in different colors—clear, black, red, and gold are most common—and are usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 “hardcoat”) is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
Electroless Nickel Plating
A sheet metal fabrication process that provides uniform nickel coating which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will be brighter. Thickness starts at .0001” and this finish conforms to MIL-C-26074.
Powder Coat
This is a sheet metal fabrication process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic. See examples of our options in our powder coating finishes gallery.
