Materials And Forming Operations In Precision Metal Stamping
Turning sheet metal into high-quality, finished products requires a high level of accuracy and consistency. Precision metal stamping is the cornerstone of this process. It enables manufacturers and fabricators to produce reliable components.
To deliver the best results, this process works hand in hand with the right materials and suitable forming operations. Gauer Metal Products has spent nearly eight decades honing these skills into an art. Understanding how it works, its capabilities, and its benefits can help you optimize this process for the best results.
Let us find out more about the materials and forming operations it requires to achieve flawless results.
What is Precision Metal Stamping?
Precision metal stamping is a manufacturing process that uses a die and press to apply force to sheet metal with the goal of creating metal components. This process is applied in diverse industries to produce high-accuracy and intricate parts for various applications.
It requires extremely tight tolerances and could involve a single-stage operation or a series operation. A single-stage operation is when the manufacturer uses a single press stroke to complete a piece. Meanwhile, a series operation requires multiple strokes.
This process stands out due to its remarkably high precision in creating complex parts that require great attention to detail and have a zero error margin. Typically, the process begins with a computer model that simulates stamping to make sure there are no defects or errors.
After this testing stage, the manufacturer sends the design to the machine for production.
Benefits of Precision Metal Stamping
- Accuracy and Consistency: Precision metal stamping produces accurate and consistent components with uniform quality and tight tolerances.
- Cost Efficiency: The process supports high-speed, large-scale production. As a result, it helps reduce manufacturing costs.
- Structural Durability: It results in products with great structural integrity and durability.
Importance of Material Selection in the Process
The material used has an impact on the quality of the final product as well as its functionality. It can also determine the cost-effectiveness of the production process and product durability.
Parts made using the right material should meet corrosion-resistance, strength, and durability requirements while remaining cost-efficient. Furthermore, they should minimize issues like warping, cracking, or excessive wear on stamping tools.
With that in mind, let us find out more about the most popular material used in the process and the factors determining the choice.
Most Popular Materials in Precision Metal Stamping
Different industries and applications call for different materials. Meanwhile, the following are the most commonly used types of metals in stamping:
- Brass and Copper: These are most popular for their electrical conductivity and are extensively used in electrical and electronic components.
- Stainless Steel: Popular for its strength, corrosion resistance, and durability, stainless steel is used in automotive components, medical devices, and industrial applications.
- Carbon Steel: This is a cost-effective option for industrial parts requiring a blend of strength and moderate resistance to corrosion.
- Aluminum: Aluminum is ideal for applications where weight reduction matters thanks to its lightweight. It is most common in aerospace and electronics.
- Nickel Alloys and Titanium: These metals have remarkable strength-to-weight ratios and resistance to high temperatures and corrosion. They are popular in high-performance industries such as medical and aerospace.
Forming Operations in Metal Stamping
Forming operations are processes that manipulate a metal’s shape into a desired form without cutting. Typically, these processes use specialized dies in a stamping press to achieve the desired features and details on the final product. The forming operations used depend on the tooling method and project requirements.
Here are some of the most common techniques:
Blanking
As one of the foundational steps in the process, blanking involves cutting specific metal shapes using a die. The cutout is known as a blank. It serves as the starter material for forming operations.
Bending
Bending deforms a metal sheet along an axis to form folds, curves, and angles, without breaking it. It involves placing sheet metal into a die and applying pressure to create the desired shape.
Punching
Punching is removing material from a metal sheet to create cutouts, holes, or slots and then discarding or recycling the excess material.
Coining
Coining uses high pressure to create surface features or detailed shapes on metal. The manufacturer compresses it between a die and a punch to reduce material thickness in certain areas.
Embossing
This process is similar to coining. However, instead of compressing material, it creates recessed or raised designs on the surface.
Progressive Stamping
Progressive stamping involves passing the material through a series of dies, each performing a different operation (embossing, bending, punching, etc.). It is ideal for high-volume productions as it combines multiple operations into one workflow.
Deep Drawing
Deep drawing creates 3D patterns by stretching metal into a die by pulling it into the die cavity. It forms cylindrical or hollow parts without seams.
