What is Laser Cutting
Laser cutting is a cutting technology with high efficiency and high precision in sheet metal processing. It uses a laser to cut metal and non-metal materials, and can obtain high-precision and high-quality cutting results. Laser cutting is characterized by fast cutting speed, flat cut, and smooth surface after processing.
How Does Laser Cutting Work?

The working principle of laser cutting is: the laser beam is focused through the optical system to generate a high-power laser spot, which heats the material to melt or vaporize, and then cooperates with the action of oxygen to separate the edge of the material to form a cutting seam.

Laser Cutting
Other Benefits of Laser Cutting
Laser cutting is suitable for cutting various metal and non-metal materials with complex shapes, especially for cutting thin plate materials, such as steel plates, aluminum plates, copper plates, stainless steel, etc. In sheet metal processing, laser cutting can save materials, improve production efficiency, and improve product quality, and has become an important technology in the sheet metal processing industry.
Features of Laser Cutting
Rapid Turnaround
The cutting speed is fast and the cutting speed is stable, which can realize cutting methods such as fast cutting and lightning cutting.
Cutting Quality
The hot zone of the sheet metal cut by the laser cutting machine has little influence, the cross section is smooth, and the incision is narrow. The roughness of the cutting section is as low as tens of microns, no secondary processing is required, and all are formed.
Material Selection
It can effectively cut metal sheets of various materials, such as carbon steel, stainless steel, aluminum, alloys, non-ferrous metals, etc.
Tight Tolerance
Laser cutting has high dimensional accuracy and can cut obtuse angles and narrow seams.
Device Restrictions
Due to the limitation of laser power and equipment volume, laser cutting can only cut medium and small thickness plates and pipes, and as the thickness of the workpiece increases, the cutting speed decreases significantly.

Sheet Metal Design Guidelines
We have summarized recommended and technically feasible values for the most common features encountered in Sheet Metal parts.
1. Avoid external or internal sharp corners
The sharp corners of the plate are easy to cause the operator or user to scratch their fingers.
2. Bending height
When the bending height is too small, the bending part is easily distorted and deformed, and it is not easy to obtain the ideal part shape and ideal dimensional accuracy.
3. Bending radius
When the sheet metal part is bent, the internal R angle is preferably≥1/2 of the material thickness.
4. Hole spacing and hole margin size requirements
The minimum distance between the edge of the hole of the part and the shape has certain restrictions depending on the shape of the part and the hole.
See the figure below, when the punching edge is not parallel to the edge of the part shape, the minimum distance should not be less than the material thickness (t), that is, a≥t; when parallel, it should not be less than 1.5t, that is, b≥1.5t.
5. Screw holes
There are three ways to fix screws commonly used in sheet metal parts.
6. Hemming of sheet metal
The length of the hemming is related to the thickness of the material. As shown in the figure below, generally the minimum length of the hemming is L≥3.5t+R.
T is the thickness of the material, and R is the minimum inner bending radius of the previous process (as shown on the right of the figure below) of the hemming. The minimum length L of the hemming.
What is sheet metal?

Sheet metal refers to a thin, flat piece of metal that can be formed and manipulated into various shapes and sizes. Sheet metal can be made from a variety of metals, including steel, aluminum, copper, brass, and nickel.

Sheet metal can be produced in a range of thicknesses, typically ranging from 0.006 inches to 0.25 inches, depending on the material and application. It can be produced in coils or sheets and can be cut, stamped, bent, or welded to create a variety of parts and products.

Sheet metal is commonly used in the manufacturing of a wide range of products, including:

1. Automotive parts: Sheet metal is used to make a variety of automotive parts, including body panels, bumpers, doors, and roofs.

2. Aerospace parts: Sheet metal is used to make components for aerospace structures, including wings, fuselages, and landing gear.

3. HVAC systems: Sheet metal is used in the fabrication of ductwork, air conditioning units, and furnace components.

4. Building construction: Sheet metal is used in the construction of roofs, gutters, and façades.

Sheet metal fabrication involves working with the metal to cut, form, and assemble it into the desired shape. Common sheet metal fabrication processes include cutting, punching, bending, and welding. These processes can be performed manually or using automated equipment, depending on the complexity of the part and the required production volume.

What types of materials are commonly used in sheet metal fabrication?

Sheet metal can be made from a range of different metals and alloys, each with their own unique properties, advantages, and disadvantages. Here are some of the most commonly used materials in sheet metal fabrication:

1. Steel: Steel is the most commonly used metal in sheet metal fabrication. It is a strong, durable, and cost-effective material that can be easily formed and welded. Steel is used to make a wide range of products, including automotive parts, appliances, and building materials.

2. Aluminum: Aluminum is a lightweight and corrosion-resistant metal, making it ideal for use in the aerospace, automotive, and construction industries. Aluminum is also readily available and easy to work with, making it a popular choice for sheet metal fabrication.

3. Copper: Copper is a highly conductive and corrosion-resistant metal that is often used in electrical and plumbing applications. It is also commonly used to make decorative objects and home furnishings.

4. Brass: Brass is a copper-based alloy that is often used in decorative applications due to its attractive golden color. It is also commonly used in the manufacture of musical instruments and plumbing fixtures.

5. Nickel: Nickel is a strong and corrosion-resistant metal that is often used in high-temperature applications, such as aerospace and industrial manufacturing. It is also used in the manufacture of coins and jewelry.

6. Titanium: Titanium is a lightweight, strong, and corrosion-resistant metal that is commonly used in the aerospace, military, and biomedical industries.

The choice of material used in sheet metal fabrication depends on the specific application, required properties of the finished product, and the cost.

What is the difference between sheet metal and plate metal?

Sheet metal typically refers to metal that is less than 6mm in thickness, while plate metal refers to metal that is 6mm or thicker.

What is the difference between sheet metal bending and sheet metal folding?

Sheet metal bending and sheet metal folding are both methods of shaping sheet metal into various forms, but they differ in the way that the metal is manipulated.

Sheet Metal Bending: Sheet metal bending is a process of forming sheet metal into a desired shape by bending the metal around a straight axis, using a press brake machine. A press brake is a machine that consists of upper and lower dies, which clamp the sheet metal securely and apply pressure to bend the material to the desired angle.

The bending process generally produces a V-shape, U-shape, or channel-shape in the sheet metal. The bend radius and angle can be controlled precisely using specialized tooling and bending dies.

Sheet Metal Folding: Sheet metal folding, also known as edge bending, is a process of forming sheet metal using a folding machine. The folding machine bends the metal along a straight axis or a curved line, producing a crisp and clean fold. The fold is typically created using a punch and a die, which grip and bend the metal along a straight or curved line, creating a fold range that can be limited to 180°.

Sheet metal folding is ideal for producing shapes with folded edges such as panels with flanges or boxes.

The choice between sheet metal bending and sheet metal folding will depend on the specific requirements of the part, including the desired shape, bend angle, and production volume. For larger volumes or parts requiring more precise and complex bends, sheet metal bending is often the preferred choice, while sheet metal folding is ideal for parts with straight edges and simple bends.

What is the minimum bend radius for sheet metal?

The minimum bend radius for sheet metal depends on several factors, including the material thickness, the type of material, and the tooling used to make the bend. As a general rule, the minimum bend radius for sheet metal should be at least equal to the material thickness.

For example, if the sheet metal is 1 mm thick, then the minimum bend radius should be 1 mm. However, certain materials may require a larger bend radius due to their physical properties. Materials that are more brittle or have a greater yield strength may require a larger bend radius to prevent cracking or deformation.

The tooling used to make the bend also plays a critical role in determining the minimum bend radius. The punch and die used to make the bend should be designed with a radius that matches the minimum bend radius of the material, ensuring that the bend is consistent and does not cause damage to the metal.

It's important to note that the minimum bend radius is not the same as the maximum bend angle. The maximum bend angle for sheet metal is generally around 180 degrees, although this can vary depending on the thickness and type of material being used. The minimum bend radius is a key consideration in sheet metal bending to ensure that the bend is precise, consistent and does not result in defects in the finished part.
