Orienson's Fine Blanking Parts

Fine blanking is a kind of precision stamping processing technology developed on the basis of general blanking. Although it belongs to the separation process with general blanking, it contains the processing method with special process parameters, and the parts produced by it also have different quality characteristics. Especially in the fine blanking and cold forming (such as bending, stretching, flanging, upset, sinkholes, piercing and squeezed, etc.) processing technology, the combination of fine blanking parts is applied to many fields, (such as automobile, motorcycle, electronic industry, etc.), which has been replaced the parts processed by blunt machining, forging, casting and powder metallurgy, and thus play its huge technical advantages and economic benefits.

What Is The Difference Between Blanking And Fine Blanking?

Fine blanking originated from ordinary stamping but is not simply an enhanced version of ordinary stamping. The essential difference between the fine blanking process and the general blanking process is that ordinary stamping can not effectively avoid the tearing of the section, and the fine blanking tries to restrain the tearing of the sheet when cutting.

Fine blanking is always maintained as a whole before the parts are separated from the sheet metal, and the sheet metal is always in the plastic deformation process during fine blanking.

Benefits of Fine Blanking Parts

High Quality

Fine punching parts have the advantages of a smooth blanking surface, high dimensional accuracy, and high flatness.

Efficient Process

For many complex shape parts, such as gear, ratchet, sprocket, CAM, and other flat parts, they can be completed once with a fine blanking process, after deburring processing can be directly assembled so as to reduce many milling, planing, grinding, leveling and other processing procedures. Therefore, the use of a fine blanking process can significantly improve the process.

Low Cost

Fine blanking avoids a lot of energy consumption and material consumption caused by the cutting process, which not only improves the production efficiency but also avoids the accuracy loss of each process, ensuring the repeated precision and production reliability of mass production parts. As a result, sometimes it can replace the sequential fire process and further reduce energy consumption and cost.

Friction Resistance of Edge Rolling Parts

Friction Resistance Performance Improved

Because the surface after fine blanking has a strong cold hardening effect, its surface hardness, strength is greatly improved, friction resistance performance is significantly improved.

Long Life Span

Those fine blanking parts that are used as a moving surface, friction surface gear tooth profile, shaft sleeve is improved its life.

Application Of Fine Blanking Parts

The application of the fine blanking process covers a wide range, has been widely used in daily life, such as watches, motorcycles, textile machinery, agricultural machinery, computers, household appliances, instruments and measuring tools, and other fields. Especially in the automobile industry, from the car transmission system, gearbox, seat and safety system, brake system, to door locks, glass lifters, shock absorbers, and so on. In addition, there are quite a number of casting and forging blanks, which can be used to replace the original cutting process to produce qualified parts, and the application prospect is broad.

After many years of development, Orienson has accumulated rich experience in R & D, design, and precision parts manufacturing with an experienced team, complete production & test equipment, welcome to enquire.

Fine Blanking Parts Design

Precision blanking is the die of a special structure, its convex and concave die edge of the material is under the action of three-dimensional compressive stress, forms a great hydrostatic pressure effect, inhibits the fracture of the material so that the material plastically shear deformation to state separation. The section of precision blanking parts is smooth and vertical to the board surface, so this kind of blanking part is high precision.

Now with the progress of modern industry, the requirements of stamping parts quality are more and more strict, precision blanking application is very extensive.
