Metal stamping parts hardness testing using Rockwell hardness tester. Small, complex-shaped stampings that can be used to test small flat surfaces can not be detected on a common benchtop Rockwell hardness tester.

Stamping parts processing, including blanking, bending, drawing, forming, finishing and other processes. The materials for stamping are mainly hot rolled or cold rolled (mainly cold rolled), such as carbon steel, alloy steel, spring steel, galvanized steel, tinplate, stainless steel, copper and copper alloy Board, aluminum and aluminum alloy plate.

PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stampings. Alloy stamping is metal processing, machinery manufacturing the most commonly used parts. Stamping parts processing is the use of mold separation or forming of the metal plate processing methods. Its application is very broad.

The main purpose of stamping material hardness testing is to determine whether the purchase of the sheet metal annealing degree is suitable for subsequent stamping parts to be processed, different types of stamping parts processing technology, the need for different hardness levels of the plate. Aluminum alloy sheet for stamping parts processing available Webster hardness tester, material thickness greater than 13mm can be changed to Barcol hardness tester, pure aluminum or low hardness aluminum alloy plate should be used Barcol hardness tester.

In the stamping industry, stamping is sometimes called sheet forming, but with a slight difference. The so-called sheet metal forming refers to the use of sheet metal, thin-walled tubes, thin profiles as raw materials for plastic processing methods collectively referred to as sheet metal forming, this time, the direction of plate deformation generally do not seriously consider. China's stamping market and technical level Because many stamping plant belong to the OEM, therefore, stamping parts market is very imperfect and sound. However, the small stamping parts market in some parts of the South is very mature. From the current situation, China's stamping parts market the following problems:

(1) some oversupply of production capacity, some of the mainframe factory stamping plant, let go, can not hold. Most of the year lack of production tasks, no market behavior.

(2) household appliances, electrical stamping parts market competition. However, there are not many enterprises with international competitiveness in a climate.

(3) careful study of stamping parts market no one to carry out. Stamping market disorderly.

In the above market conditions, technological development is limited, the entire industry is also behind, manifested in:

(1) Low overall level, excess capacity in many industries and lack of high-end technology. Technical progress is slow.

(2) Material technology, mold technology, lubrication technology and equipment level are all at a low level, far from meeting the needs of domestic production and development.

Through the understanding of current products, it is also possible to know how extensive the fields of application of springs such as compression springs basically cover various fields such as machinery, hardware and electrical appliances.
