What are the advantages of metal stamping
2020-05-05 566
Compared with other methods of mechanical processing and plastic processing, stamping has many common advantages both in technology and economy. The main performance is as follows.(1) the stamping process has high production efficiency, convenient operation and easy completion mechanization and automation. This is because stamping depends on stamping die and stamping equipment to complete the proc

How to test metal stamping parts
2020-05-05 576
Rockwell hardness tester is selected for hardness test of hardware stamping parts. Small stamping parts with complex shape can be used to test the small plane, which can not be tested on ordinary Rockwell hardness tester.Stamping process includes blanking, zigzag, drawing, forming, finishing and other processes. The processing data of stamping parts are mainly hot-rolled or cold-rolled (mainly col

What properties should metal stamping molding sand have
2020-05-05 559
The quality of molding sand and core sand has a direct impact on the quality of castings. Poor quality of molding sand will cause defects of castings such as porosity, sand hole, sand sticking and sand inclusion. Outstanding molding sand shall have the following functions:1) air permeability typeAfter the high temperature liquid metal is poured into the mold, the mold is filled with a large amount

What are the processes of metal stamping parts
2020-05-05 548
The primary and fundamental processes of stamping are blanking, punching, zigzag and drawing:(1) blanking and punching blanking and punching are processes to separate the blank. Blanking and punching process is exactly the same, just for different purposes. During blanking, the separated part is the finished product, and the remaining periphery is the waste material; punching is to obtain the hole

What are the processing technologies of metal stamping
2020-05-05 522
In stamping industry, stamping is sometimes called sheet forming, but there are some differences. The so-called sheet forming refers to the forming method of plastic processing with sheet, thin-walled tube, thin profile, etc. as raw materials. At this time, the deformation in the direction of thick plate is generally not considered.PHP series portable external Rockwell hardness tester is very suit
