Ultimate Guide to Deep Draw Metal Stamping
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 ProcessDeep 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 DesignEvery 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 MaterialOnce 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 OperationIn 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 StampingIn 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
