China Custom Sheet Metal Stamping Process

What is China custom sheet metal stamping?

China custom sheet metal stamping requires three essential elements: sheet metal material for manufacturing parts, stamping dies, and stamping machines. The inclusion of stamping dies usually means that China custom sheet metal stamping is carried out on a large scale for replicating parts. The China custom sheet metal stamping we are discussing mostly involves cold forming, where the die is pressed into the metal using the force and compression from the press to obtain the final product. This process does not require any machine or manual heating to be introduced into the die or sheet metal, hence the surface of the die does not undergo thermal deformation. This makes metal stamping both economical and environmentally friendly.

Common processes in China custom sheet metal stamping

Forming

The process of using China custom sheet metal stamping machines and dies to transform the metal sheet into another geometric shape, depending on the design specifications of the part.

Blanking

Blanking is a shearing and cutting process. The die cuts out the workpiece (blank) from a large metal sheet for the next stage of processing. Since blanked parts have very few burrs, it helps to reduce finishing costs and delivery time.

Punching

Contrary to blanking, punching uses a punch and die to create holes, slots, and other openings in the metal sheet. Punching can strictly follow tolerances and the cut edges are cleaner than drilling.

Embossing

When the finished metal requires design patterns, embossing presses the workpiece blank onto the die with specific shape patterns, causing the surface of the blank to create raised or recessed patterns.

Drawing

Drawing fixes the edges of the metal sheet and carefully pulls the material into the die cavity to the required thickness and shape, resulting in very smooth and flowing sheet parts. Drawing is often used for aircraft parts, electronic components, and in automotive manufacturing for smooth shapes like car bodies.

Stamping

Stamping also creates patterns and information on metal sheets, but the principle is to create on one side of the metal sheet without causing the opposite side to have a recessed/raised effect.

Materials for China custom sheet metal stamping

The metals used for China custom sheet metal stamping need sufficient strength to support the finished product, and also need flexibility and ductility to ensure smooth geometric shapes during stamping. Depending on the properties required for the finished product, metals used for precision stamping are typically in the soft to medium hardness range. The categories of metals commonly used for China custom sheet metal stamping are: ferrous metals, precious metals, non-ferrous metals, and non-standard alloys.

Advantages of choosing China custom sheet metal stamping

Low die cost

Although China custom sheet metal stamping requires additional die costs, its die costs are lower than those used in other common processes, with more refined and automated machinery. Stamping machines also require computer program control, and the edges of stamped finished products are cleaner, achieving higher precision and turnaround time.

Environmentally friendly process

The impact of China custom sheet metal stamping pieces on customers' expectations for products also reflects the manufacturing company's ability to handle the project. To achieve your goals, it is crucial to have experienced and qualified personnel and the right hardware equipment. A high-quality China custom sheet metal stamping company knows when to choose certain stamping forms and how to use the process. We understand and can provide you with a one-stop production program.
