Benefits of Forming Deep Drawn Metal Parts
The deep drawing metal forming process is a cold forming process performed in an environment at or near room temperature, below the material’s recrystallization point, where the metal is permanently deformed into the desired geometry. In this process, the flat metal blank is formed and stretched around a die cavity with a punch, typically done by a mechanical or hydraulic press. As the materials is drawn into the die cavity, it flows to conform precisely to the contours of both the die and the punch, taking its shape, and resulting in a cup, housing, or enclosure.
The dimensions on the part are set based on the shape of the plug, the shape of the die, and how depth of the draw. Deep drawing is ideally suited for applications requiring their depth to be greater than their radius, while providing excellent structural integrity and ductility due to material work-hardening and localized thickening as the blank is drawn into the die cavity.
Seamlessly Formed
- Fewer failure points or weak joints
- Higher load-bearing strength
- Increased longevity
- Smoother product flow
- Can handle heavy-duty applications
- Ideal for waterproof or airtight applications: because of their seamless build, deep drawn parts can be leak-proof
- Reduces the need for secondary metal forming operations
Uniformity and Reduced Defects
- Higher product quality
- Improved structural integrity
- Production repeatability and consistency ensures that every part is formed with the same specifications, reducing defects like wrinkling, or tearing
- Lower scrap rates
Rapid Cycle Times
- Can be automated or partially automated, allowing for continuous operation
- The deep drawing process is done with the stroke of a press, forming a single metal blank over a die. This can be done in just one operation
- Eliminates the need for further fabrication, welding, or other secondary processes minimizes the production cycle time
Fast assembly
- Oftentimes deep drawn metal applications do not require a weld, or further forming.
- Because of its seamless construction, a part taken directly off the press can be washed and boxed up for shipping
Durable, Ductile, and Strong
- The deep drawing process exerts a great amount of compression on the metal during the forming process, increasing its long-term strength. The metal’s fundamental structure is often highly compressed into a hard crystalline structure.
- Excellent Structural Integrity
