Metal stamping is a manufacturing process that involves cutting and shaping metal metal to create various products. Deep draw metal stamping is one the most popular types. This process involves feeding sheet metal through a series of dies to create cylindrical or box-shaped products.

Trans-Matic specializes in creating intricate and precise parts for its customers. We are renowned for our expertise in deep draw stampings and have built a reputation for reliability and trust over the past 50 years.

This guide will explore everything you need to know about deep draw metal stamping, including its process, benefits, and applications. We will also discuss additional procedures utilized during this operation.

The Deep Draw Metal Stamping Process

Deep draw metal stamping is a highly specialized and precise metal forming procedure for making high-quality items with complex geometries and tight tolerances. The three steps to deep draw metal stamping are as follows:

Step 1: Planning the Part Design

Every deep draw metal stamping process starts with planning the part design. Manufacturers such as Trans-Matic determine the required dies and punches based on the end product’s size, shape, and customer specifications. During this phase, factors such as the dimensions of the part, the design complexity, and the production method must be considered.

Step 2: Selecting the Right Material

Once the part design is complete, the manufacturer selects the best-suited material based on the product specifications and the customer’s requirements. Popular materials used in deep draw metal stamping include brass, copper, low-carbon steel, stainless steel, and aluminum.

Step 3: Performing the Stamping Operation

In the last step, the blank material is formed into the final part shape through a series of draws or reductions. The number of draws or reductions required depends on the part design, material type, and thickness. Each station decreases the diameter and increases the height of the material.

Additional Processes in Deep Draw Metal Stamping

In addition to the fundamental deep draw stamping process, numerous procedures are used to improve the end product’s quality and precision. Among these procedures are the following:

• Bending: shaping the metal sheet into a curved or angled shape
• Bulging: expanding the diameter of a cylindrical part in a controlled manner
• Coining: applying high pressure to the metal sheet to compress and refine the surface
• Dimpling: creating a depression or indentation on the exterior of the product output
• Embossing: producing a raised or recessed design on the surface of the final product
• Extruding: generating a continuous shape or profile by forcing material through a die
• Piercing: making holes or other features in the metal sheet
• Ironing: thinning the walls of a deep draw part
• Marking: adding text or symbols to the surface of the end product
• Necking: reducing the diameter of a cylindrical portion in a controlled manner
• Notching: making a groove or cutout in the final result
• Threading: creating screw threads on the surface of the production
• Trimming: removing excess material from the output

Benefits of Deep Draw Metal Stamping

The following are the top advantages of using deep draw metal stamping for manufacturing parts:

Cost-Effective Production

Deep draw metal stamping can produce complex parts with high precision at a lower cost than other metal forming processes, such as casting or machining. This process allows for the mass production of components with consistent quality, reducing material wastage and labor costs.

Versatile Material Selection

This technique can work with a wide range of materials, which allows manufacturers to choose the most suitable material for their specific application.

Consistent Quality

Highly precise tooling and presses used in deep draw metal stamping ensure consistent quality across all parts produced. In addition, the process can achieve tight tolerances and accurate dimensions, reducing the need for additional machining or finishing.

Complex Part Design

Deep draw metal stamping can produce complex part designs with multiple shapes, angles, and curves. It allows for creating parts that would be difficult or impossible to achieve with other metal-forming methods.

Enhanced Strength and Durability

By raising the material density of the component and decreasing porosity, deep draw metal stamping can increase the strength and durability of the finished product. This makes it an excellent method for producing items requiring high tensile strength or structural integrity.

High-Quality Finishes

This process can produce parts with smooth, consistent surfaces, free from the usual imperfections of other manufacturing processes.

Fast Turnaround

Deep draw stamping can be a very fast manufacturing process. This can be particularly important for industries where time-to-market is critical, such as electronics.

Applications of Deep Draw Metal Stamping

Deep draw metal stamping has wide applications across several industries. Here are some of its most common applications:

Automotive

The automotive industry relies heavily on deep draw metal stamping to produce various components, such as fuel systems, engine, and transmission components.

Medical

Deep draw metal stamping is employed in the medical sector to create parts for various medical devices. This includes surgical instruments, implanted devices, and diagnostic tools.

Aerospace

This procedure is utilized in the aerospace sector to manufacture components like sensors, fittings, compressor discs, and numerous other parts used in aircraft engines.

Electronics

Deep draw metal stamping is used in electronics to make various parts, including enclosures, connections, and heat sinks.

Consumer Goods Industry

The consumer goods sector utilizes deep draw metal stamping to create kitchen appliances, lighting fixtures, and other home furnishings.

Factors To Consider in Deep Draw Metal Stamping

Deep draw metal stamping requires careful consideration of various factors to achieve high-quality results. Some of the most important factors to consider when undertaking a deep draw metal stamping project include the following:

Material Selection

The choice of material is one of the most important factors in the success of any deep draw metal stamping project. The material’s strength, ductility, formability, and corrosion resistance are some factors to take into account. Other considerations include cost, availability, and the specific requirements of the final product.

Die Design

The design of the stamping die is important to the project’s success. The die must be meticulously developed to generate the desired form with the needed accuracy, consistency, and repeatability.

Lubrication

Proper lubrication is essential for reducing friction and heat buildup during stamping. This helps to prevent damage to the die and the workpiece and improves the quality of the finished product.

Tooling

The tools must be designed to produce the required shape precisely. They must also be kept in good condition to ensure consistent results.

Production Volume

The volume of produced parts is an important factor to consider when planning a deep draw metal stamping project. High-volume production may require specialized equipment and tooling, while low-volume runs may be more feasible using simpler equipment and processes.

Quality Control

Quality control measures include regular inspection of the parts being produced. This also entails testing for dimensional accuracy and material properties and ensuring consistency and repeatability.
