7 Steps for Perfect High-Precision Stamping Part Manufacturing


High-precision stamping part is the shaping of a material under the action of an external force in order to obtain the desired part. It takes a lot of effort to machine the work piece in this way. Moreover, for this, there is equipment that comes with an effort of 16 to 500 tons.

High-Precision Stamping Part

The tooling installed in the press is a stamp. In it, there is a direct contact of the working tool with the precision. Similarly, for 1 stroke of the machine, a part of a high degree of accuracy is obtained.

High-Precision Stamping Part

The history of the process

Stamping of precision products started in the 16th century. This was due to the development of weapons production, where it was required to obtain a large number of identical parts. In the 19th century, the rapid development of stamping production began.

In addition, household items are produced. There is a need to manufacture high-quality serial products.

With the advent of the automotive and shipbuilding industries, precision forming has taken a key position in the development of these industries. With the help of high-precision stamping part, dimensional parts began to be produced.

High-Precision Stamping Part Areas of Use

Industrial production is not complete without cold and hot stamping. Using these methods, you can create both small and large parts in a short period of time. Furthermore, hot stamping is common where three-dimensional parts need to be obtained.

When stamping flanges, 2 methods are common:

  1. Hydraulic presses are common in the forging high-precision stamping part, Here, under the influence of pressure, the precision flows into the cavity, which comes in the striker. This space corresponds to the shape of the resulting part.
  2. When using sheet precision as a work piece, crank presses are common. Moreover, a stamp inserts into them and sheet precision is fed. Similarly, the flange draws under pressure.


The essence and purpose of sheet high-precision stamping part

Cold stamping is the most popular technology for manufacturing Keyword: high-precision stamping part and polymers. The versatility of the method lies in the fact that it allows the production of structures of any size: from kitchen utensils to elements of large ships.

Cold sheet plastic deformation is appreciated for the following benefits:

  1. Endless possibilities for mechanization and automation of the process.
  2. Low production cost.
  3. High utilization rate of the material.
  4. In the manufacture of thin-walled elements, the strength of the structure does not reduce.
  5. There is no need for finishing the finished product.

High quality and manufacturability have a downside: it requires qualified specialists to set up equipment. In addition, designing a high-precision stamping part is a time consuming operation.

Stamping technology

The technology of manufacturing parts by stamping both hot and cold presupposes the presence of tooling. Similarly, for both types, stamps have certain differences. Hence, they are good for metal that has a different degree of thickness.

Cold forming operations

Any working operation of high-precision stamping part can attribute to the group of separating or shaping actions. Let's consider the main procedures:

Cutting: The operation involves cutting the material along a straight or complex line. Moreover, various types of scissors or guillotines are common as working equipment. Cutting is easy to perform both at the start and at the finish stage of high-precision stamping part.

  1. Get a free-form hole.
  2. Cutting down. Cutting the structure along a closed contour. In this case, the separated part is a part, and not a waste, as when punching.
  3. The operation of creating a side along the outer or inner contour. Most often, the procedure carries out on the end of the pipes, in the places where the flanges install.
  4. Convert a flat product to a hollow volumetric part. Moreover, the process comes by a change in wall thickness.
  5. Reducing the size of the end part by crimping in a conical die.
  6. Giving a curved shape to flat parts. Similarly, the most common are V and U bends.
  7. Change the local shape of the part while maintaining the dimensions of the outer contour.

High-Precision Stamping Part Equipment Classification

Basically, the stamping press is a machine with a crank or hydraulic drive. Moreover, there is a wide variety of equipment on the market. The characteristics of stamping lines differ in strength and dimensions of the processed materials. Similarly, high power machines are not required for soft precisions.

Stamping production and equipment for it are regulated by the requirements of interstate standards. In addition, GOST establishes the maximum permissible consumption of materials and approves the rules for the development of projects.

Consider the equipment that is common in High-Precision Stamping Part.

Crank Presses

The principle of operation of the equipment comes on the conversion of the crank mechanism of the torque into the reciprocating movement of the slide.

Such equipment classifies as a simple type of mechanism. Moreover, they can be double or triple acting.

Hydraulic presses

The most powerful equipment capable of developing an effort of up to 2 thousand tons. The principle of operation is based on the movement of two hydraulic cylinders of different diameters. The magnitude of the difference in size determines the degree of impact on the surface. Similarly, the fluid moves in special electrically driven pumps.

Radial forging presses

They are a molding press for the production of parts of a cylindrical configuration. The complete set of the machine includes an induction furnace for preheating blanks.

The High-Precision Stamping Part is common to produce square, round or rectangular forgings.

Electromagnetic High-Precision Stamping Part presses

This is a product of modern technology. Furthermore, the driving force is the energy of the electromagnetic field, which presses on the wire-wound core. In the process of moving, it acts on the executive part of the machine.

Automatic stamping lines

Modern machine tool enterprises offer a wide range of automatic High-Precision Stamping Part lines and complexes for solving various problems.  Similarly, the machines are high-tech equipment manufactured under the guidance of qualified process engineers.

Modern complexes come with CNC systems with a central touchscreen display, which reduces the operator's functions to a minimum.

High-Precision Stamping Part is a popular technology that allows the production of parts with high performance characteristics. Do you think semi-automatic machines can compete with numerical control or such equipment outdate? Hence, you can share your opinion in the comment section.
