Precision Metal Stamping

Industries use precision metal stamping when turning metal sheets into required shape and size for parts used in their products. These products are used in cars, airplanes, industrial engineering, defense items, electrical and electronics, and the list continues. Eigen is equipped with the latest machinery, technology, manufacturing unit, and an exceptional team of experienced precision metal stamping professionals to serve you with great results.

Precision metal stamping is a combination of various operations such as stamping, folding, drawing, and piercing. It is either a single operation or a series of multiple operations depending upon the parts being stamped.

What is Precision Metal Stamping

Precision metal stamping uses a wide range of types of machinery and presses fixed with dies to convert a flat sheet metal also known as a coil to convert into a wide range of forms. Presses ranging from 20 tons to 10,000 tons are used in stamping various metals into the desired shapes. Most common materials used in stamping are steel, aluminum, and copper. There is increased competition in the manufacturing industry, and this pushes the stamping industry to deliver a great level of quantity and quality. Accuracy is a big advantage with this approach, as you can receive a high volume of exact specifications. And, that is the reason, precision metal stamping is preferred over several other processes.

Materials Used in Precision Metal Stamping

The type of material used in the metal stamping process is crucial to decide how much force is needed to cut and give it the desired shape.

Precious Metals: Gold, silver, and platinum. This type of metal is expensive but there are still many industries that are widely using these for their requirements.

Ferrous Metals: These include Iron-based alloys, such as stainless steel. Low cost and lower unit production prices make them the most commonly used in stamping operations.

Non-Ferrous Metals: Bronze, brass, and zinc.

Specialty Metals: Titanium and nickel. This type of alloy is tailor-made for specific applications.

Different Steps in Precision Stamping

Depending upon the type of metal, expected shape, and size  metal may go through different stages of cutting and forming, and some of them are:

CAD/ CAM technology

Punching: Punching creates a hole in the flat materials like sheet metals via shearing and removes a scrap slug from the metal piece. This process is used to produce holes of various shapes quickly.

Blanking: During blanking cuts, a metal workpiece is removed from the primary metal sheet. The rest of the metal is set aside.

Bending: As the name suggests, the bending process folds a metal along a straight axis to give it different shapes. This process is used to create finished products in metal stamping.

Coining: The coining process is widely used in this approach. Very high pressure is given to the metal to get a finished part with crisp edges.

Drawing: Drawing uses tensile forces to stretch metal into thinner form to give it the desired thickness and shape.

Embossing: Embossing is used to create raised or sunken designs and images on metal surfaces.

Flanging: Flanging is like bending that folds a metal along an axis. However, instead of straight-line, it bends the metal in 90 degrees.

Shearing: Shearing is used to cut a metal along a straight line. This metalworking method is best for producing rectangular or square large blanks of sheet metal.

Trimming: This is a finishing operation that cuts the excess material from a finished or nearly finished part from the blank. The leftover metal can either be sold or recycled.

Steps to Achieve High-Quality Parts through Precision Metal Stamping

This stamping approach is a complex process. Other than the cutting and forming operations involved in sheet metal stamping, you need to perform multiple other steps to get a high-quality finished part.

Planning and Design: The first step for creating a high-quality finished part is planning and designing a custom tooling to meet the specific needs. A prototype is created to be sure about the specifications planned for the actual part.

Preparation of Dies: A stamping die is a specially shaped tool that is used to cut or shape material by using a press. It is customized to the items that are planned to be created using the die.

Cutting and Forming: A series of cutting and forming processes are performed to give the desired shape to the metal piece.

Quality Check: After the final part is received, it goes through a rigorous quality check to keep up with the industry standards.

Benefits of Precision Metal Stamping

Precision is crucial in metal stamping and this process has been used for several years due to the many benefits that it provides. Some advantages of precision metal stamping process include:

  • Produce a large volume of parts with quick turn-around times.
  • The cost of dies is cheaper in the long run.
  • Secondary cost like the cost of cleaning and plating is significantly low in stamping compared to other metal fabrication processes.
  • Stamping uses high-end automation programs to offer greater accuracy and precision in metal stamping.
