Metal Sheet Forming Process

The most serviceable process used in metal sheet forming is deep drawings. It is one of the most popular methods used in metal forming available to manufacturers. They form blank sheets of metal into a desired shape. The metal forming process is called deep drawing when the depth of the item created is equal to or greater than its radius.

Metal sheet forming process

  • The material used is a metal blank.
  • The single blank is used to facilitate the creation of parts or products with deeper shapes.
  • These metal blanks are placed on a reel to enable the metal to form efficiently.
  • At every step of the process of deep drawings, the metal blank is shaped through pressure applied by a metal die.

Benefits of this type of metal formation

Unit cost decreases as unit count increases. Once the tooling and dies have been created, the process continues smoothly with very little cost and operation. Construction tools are lower in comparison to similar manufacturing processes.

  • More advantages in functionality

When considering the functionality of the end product, deep drawing poses still some advantages. The technique is particularly ideal for products that require significant strength and minimal weight.

  • Deep drawings are perhaps most useful for creating cylindrical objects

A circular metal blank can easily be drawn down into a 3 dimension circular object having one draw ratio, time and cost cutting in both productions. One popular example of this method is the production of the aluminum can.

Other factors that affect cost-effectiveness

  • Increase cost in manufacturing.
  • Diminishing appeal for deep drawing.
  • Increase in the maintenance of complex products.
  • Obvious increase in maintenance costs.
  • Labor costs and production costs.

Limitations of conventional deep drawings

Limitations are a barrier for some its industrial uses. Radial drawing and tangential compressive stresses are common concerns in wrinkling, fracturing in some tasks. Numerous unconventional deep drawing techniques have recently been implemented that have significantly increased deep drawing uses in industries. These processes include: aquadrawing process, Guerin process, hydraulic deep drawing process, hydroforming process, hydro-mechanical deep drawing process and the Marform process.

Virtually all manufacturing industries will benefit potentially from manufacturing process of deep drawing. The technique is perhaps most useful for manufacturing tiny parts of component as relays in electronics, solenoids, and assembly housings. Products of all designs, forms and dimensions, however, can be manufactured economically using the process, Consider such items as cookware, kitchen sinks and cans.

Conclusion

Deep drawing applications also benefit from the widest array of metals that can subjected efficiently to the process. Many types of metals are currently used to manufacture products through deep drawings.
