The Art and Science of Sheet Metal Forming Processes From Your Trusted Supplier

Sheet metal is a versatile, ubiquitous raw material found in a plethora of products in a variety of industries. Unearthing the secrets to forming this commonly used material can be a treatise in both art and science. This will delve into the world of sheet metal forming processes brought to you by your leading supplier.

The Basics of Sheet Metal Forming

Sheet metal forming mainly involves transforming flat sheets of metal into shapes. These metal sheets can be thin or thick, metal or alloy, each possessing unique characteristics that influence the forming process. For those new to the industry, the most common metals used are steel, aluminium, zinc, copper, brass and nickel.

Processes to Shape

Mastering the techniques of sheet metal forming involves an array of processes.

Bending

The simplest form of sheet metal forming is bending. This process includes applying force to a piece of sheet metal, causing it to bend at an angle and form the desired shape.

Deep Drawing

Deep drawing involves pulling a sheet metal blank into a forming die with a punch. This process is often used to create cups, cans, sinks, and automotive parts such as panels and gas tanks.

Hydroforming

Enhancements in technology have made it possible to employ high-pressure hydraulic fluid to shape sheet metal. Hydroforming is a cost-efficient way to shape ductile metals such as aluminium, brass, low alloy steels, and stainless steel into lightweight, structurally stiff and strong pieces.

Tools and Dies

Tools and dies form the bedrock of sheet metal forming processes. They facilitate the shaping, cutting and moulding of sheet metal into the desired design. The tandem usage of punch press and dies results in a fine, crisp output.

Advancements to Look Out For

As your trusted supplier, we are committed not only to providing you with top-line sheet metal but also informing you about the advancements related to sheet metal forming processes.

3D Printing for Dies

Customization of sheet metal processing services

We provide metal cutting and bending services to assist customers in sheet metal component processing. Automated cutting processes can ensure high precision and quality of finished components.

laser cutting

A cutting process that can be used to cut metal and non-metallic materials of different material thicknesses. The laser beam that has been guided, shaped, and assembled lays the foundation for this.

Metal punching

A common manufacturing process used to produce large quantities of metal components. It utilizes mechanical operations to shape metal sheets at high speeds through a stamping machine according to mold design trends, in order to achieve the desired shape and size.

Bending

It involves applying force to sheet metal parts to change their geometric shape. This force will generate stress on the metal plate that exceeds its yield strength, causing physical deformation of the material without rupture or failure.

Sheet Metal FAQs

During sheet metal processing, due to the characteristics of materials and processing methods, parts can deform. The solution is to adjust the processing technology and methods, strengthen the support and fixation of materials, and use automated processing equipment to solve the problem.

Welding quality issues in sheet metal processing may lead to issues such as insufficient component strength, porosity, and cracks. The solution is to use high-quality welding materials and equipment, strengthen monitoring and control of the welding process, and ensure that the welding quality meets the requirements.

After the sheet metal processing is completed, surface treatment is required, such as spraying, electroplating, etc. Poor surface treatment may lead to corrosion, oxidation, and other issues. The solution is to use appropriate surface treatment methods and equipment, strictly control the quality of the surface treatment process, and ensure that the surface treatment effect meets the requirements.

During sheet metal processing, dimensional deviations may result in parts being unable to be assembled or poorly assembled. The solution is to strengthen dimensional control and monitoring during the machining process, use high-precision equipment for machining, and compensate for dimensional errors during the machining process.

Quality issues may occur during sheet metal processing, such as surface burrs, cracks, pores, etc. The solution is to strengthen quality control and inspection, use advanced testing equipment and methods, and ensure that the quality of each product meets the requirements.
