Understanding Deep Stamping and Drawing Technology

Deep stamping stretching is a popular metal forming process that is favored by manufacturers due to the cost savings of mass production. There are many problems with this technology, such as: What is deep stamping stretching? Deep drawing mold attention?... See the article below for the answers to these questions!

What is deep stamping and stretching

Stamping is a sheet metal process. Place the metal plate into the mold and shape it with a punch. This process is called "deep" stretching when the part to be formed is deeply greater than its diameter (at least twice its diameter). This process is called a "shallow" stretch when the depth of the part to be formed is less than 0.3 in diameter.

A flat metal plate will be placed on the positioning ring of the mold. The punch presses the metal sheet into the mold to form a mold-like shape. The punch tensile tool (die, punch, etc.) produces the load or energy required to suppress the material during stamping.

During deep stamping, the material changes into the shape of the mold. This molding is controlled by the pressure applied to the workpiece and the lubricant (deep-pulled oil) applied to the workpiece or mold.

Each stamping operation is a separate step, each reducing the diameter and increasing the height of the part. One or more stampings may be required to produce the desired final shape. To determine the number of stamps, it must depend on the following factors: material type, material thickness, corner and bottom radius, and the shape of the product.

Benefits of deep stamping and stretching

Deep processing is particularly useful in mass production: once the tools and molds are created, the stamping process can be performed continuously, and the downtime or maintenance time is very short. And as the number increases, the cost will be greatly reduced. The cost of making stamping molds is also lower than a similar manufacturing process. The technology is ideal for products that require high strength and low weight. This process is also recommended for products whose shape cannot be achieved by other manufacturing techniques.

The most useful solution for creating cylindrical hollow objects that reduces production time and cost (Manufacturing medicinal metal cans, metal bottles, and beverage bottles) Squares, rectangles, and complex geometries may produce slight complexity but can still be easily and efficiently created. Often, as the geometric shape's complexity increases, so does the production cost.

In short, deep stamping and stretching are the ideal manufacturing solutions in metalworking.

Characteristics of deep flush parts

Seamless parts: deep flush parts are made of metal plates.

Fast cycle: A large number of products can be easily produced by this method.

Complex axial geometry: deep stamping stretching provides excellent detail and precision.

Reduce technical labor: high precision can produce the same results as technical labor.

Products for deep stamping and stretching applications

Products can be made by deep stamping and stretching of various metals. Some suggested labels include: pure iron, aluminum, brass, copper, cold-rolled steel, stainless steel, nickel, copper alloy, loseable alloy, etc.

Products made from deep stamping and stretching are very diverse, ranging from products less than 1cm in diameter to aircraft parts, automobiles, and large equipment. Deep stamping tensile processing is also widely used in cans, battery boxes, fire extinguishers, sinks, and other household items.
