What is a precision stamping die and what are the characteristics of a precision die?

A fine blanking die is a die used in the precision blanking process and is a key tool in precision stamping technology. Fine blanking is a special blanking process, which can produce parts with high precision, no burr, flush cutting surface and no subsequent processing.
The products made by fine blanking die are usually some metal stamping parts with high precision and high quality requirements. There are many things made by fine blanking dies: for example, engine parts, gears, brake components, seat frames, etc. in the automotive industry. Precision connectors, circuit board mounting brackets, housings, etc. in the electronics industry. Compressor parts, motor components, control panel frames, etc. in the home appliance industry. Precision structural parts, transmission parts, etc. for the construction machinery industry.

Stamped parts made by fine blanking die have the following characteristics:
1、High precision: the dimensional accuracy of the products made by fine blanking die is very high, which can reach the tolerance requirement of micron level, and the surface is smooth, which does not need to be machined or polished subsequently.

2、No burr: The edges of the products produced by fine blanking process are flat and burr-free, which can be directly used for assembly without deburring treatment.

3, complex shapes: fine blanking molds can be manufactured with complex internal and external contours of the parts, such as automotive parts in the precision gears, electronic equipment shells, medical equipment parts and so on.

4, high strength: fine blanking process of the pressure exerted on the material, making the stamped parts have a high internal and surface quality, and therefore have better mechanical properties and strength.

 5, one-time molding: through the fine blanking die, can be in a stamping process to complete a number of shapes of molding and size of the precise control, greatly improving production efficiency and economic benefits.

Complex structure of fine blanking dies: Fine blanking dies are usually designed with precise crimping devices, such as toothed ring platen or other forms of strong crimping mechanism, to ensure that the metal sheet is fully pre-pressurized during the punching process, and to reduce the possibility of tearing of the material in the shearing process.

High precision of fine blanking dies: The cavity part of the die has extremely high dimensional accuracy and flatness, ensuring that the punched parts have strict dimensional tolerances and excellent flatness.

Sharp and wear-resistant punching edges of fine blanking dies: the edges of the dies are made of high-quality die steel and are precision machined and heat-treated to ensure that they have sufficient hardness and wear-resistance to maintain stable punching results in the long term.

Perfect cooling system of fine blanking dies: In view of the large amount of heat in the fine blanking process, the dies are usually equipped with a perfect cooling system to ensure that the temperature of the dies is effectively controlled during the continuous production process, so as to maintain the precision of blanking and prolong the life of the dies.
