Stamping

Using a press and dies to transform flat sheet metal into a variety of complex shapes, such as stamping, laser cuting and bending.

What is Stamping?

Stamping

Stamping manufacturing is a process that uses stamping presses and dies to transform flat sheet metal into a variety of complex shapes. The process involves using a machine press to apply pressure to a sheet of metal, forcing it into a die to create a specific shape or cut.

The process is commonly used to create parts for a wide range of products, from small electronic components to large automotive parts. The benefits of stamping manufacturing include high accuracy, repeatability, and efficiency, which can lead to cost savings and improved product quality.

Material

Stamping is a metalworking process that involves pressing or punching a flat sheet of metal into a desired shape. The type of material and product that is suitable for stamping manufacturing will depend on the specific requirements of the project.

Some common materials used in stamping manufacturing include:

Steel: This is the most commonly used material in stamping manufacturing due to its strength, durability, and affordability. It can be used for a wide range of applications, including automotive parts, appliances, and construction materials.

Aluminum: Aluminum is lightweight, corrosion-resistant, and has a high strength-to-weight ratio, making it a popular choice for stamping manufacturing in the aerospace, automotive, and electronics industries.

Copper: Copper is a highly conductive and corrosion-resistant material that is commonly used for electrical and plumbing applications.

Brass: Brass is a durable and corrosion-resistant alloy of copper and zinc that is commonly used for decorative items, as well as plumbing and electrical components.

Products

Automotive parts: Stampings are used to manufacture a wide range of automotive components, including body panels, brackets, and chassis components.

Electronic components: Stampings are commonly used to produce electronic components such as connectors, terminals, and contact plates.

Appliances: Many appliance components are manufactured using stamping, including oven racks, refrigerator shelves, and washing machine parts.

Aerospace components: Stamping is used to produce a wide range of aerospace components, including structural components, brackets, and fittings.

Bending Press

A bending press, also known as a press brake, is a machine tool used in metalworking to bend and shape metal sheets into various shapes and angles. It is commonly used in industries such as automotive manufacturing, aerospace, construction, and metal fabrication.

The basic components of a bending press include a frame, a hydraulic or mechanical ram, a bending die, and a back gauge. The frame of the press is typically made of steel and provides a stable foundation for the machine. The ram is the moving part of the press that applies the bending force to the metal sheet. The bending die is a shaped tool that is mounted onto the ram and used to form the metal sheet into the desired shape. The back gauge is an adjustable stop that helps ensure accurate and consistent bending of the metal sheet.

Bending CNC

The bending process involves placing a metal sheet on the press bed, adjusting the back gauge, and lowering the ram onto the sheet to apply bending force. The bending die shapes the sheet to the desired angle. Between bends, the back gauge is adjusted for accurate positioning. Bending presses vary in size, capable of handling sheets meters long and millimeters thick. They operate manually or through CNC programming, ensuring precise bends.

These presses are crucial in metalworking, offering a reliable and efficient means to bend and shape metal sheets into diverse angles and shapes. Their versatility caters to a wide range of metal fabrication needs across various industries.

Material and Application

Defense: Producing military equipment parts like armor plates and ammunition components.

Stamping manufacturing excels in high-volume, precise production of complex parts. It’s a cost-effective, efficient method for creating numerous identical parts across various sectors.

Surface Finish

Metal products can have various surface finishes, including:

01. Polished finish

This is a smooth, glossy finish achieved through polishing or buffing the metal surface. It is often used for decorative purposes and to enhance the appearance of the product.

02. Brushed finish

This is a textured finish achieved by brushing the surface of the metal with a wire brush or abrasive pad. It is often used for products that require a non-reflective surface, such as appliances and machinery.

03. Matte finish

This is a non-glossy finish achieved by sandblasting or chemically treating the surface of the metal. It is often used for products that require a low reflectivity and a high level of durability, such as automotive parts and industrial equipment.

02. Anodized finish

This is a surface treatment that creates a thin, protective layer on the surface of the metal. It can be used to enhance the durability and corrosion resistance of the product, as well as to add color and texture.

02. Powder-coated finish

This is a surface treatment that involves applying a layer of powdered paint to the surface of the metal and then baking it on. It is often used to provide a durable, corrosion-resistant finish in a wide range of colors and textures.
