How to check forging raw materials
Forgings before forging processing, need to go through a procedure, have to test the quality of its raw materials, to ensure that the raw materials have no quality problems before the next process, now we will look at what requirements it has. 一. General requirements for forging raw materials. 1...Read more -
The advantages of stainless steel flanges are introduced
(1) Stainless steel flanges have low hardness and good toughness data, such as low carbon steel and aluminum alloy. It has low hardness and good toughness. It is difficult to cut chips and easy to form chips during cutting, which affects the quality of the surface. Therefore, stainless steel flan...Read more -
What is the cause of flange leakage?
What is the cause of flange leakage? French factory staff summarized the following seven leakage reasons, hoping to help friends in need. 1, flange leakage reason: wrong mouth A staggered joint is where the pipe and flange are perpendicular, but the two flanges are not concentric. The flange is n...Read more -
Stainless steel flange die forging equipment and application characteristics
The mechanical properties of the forgings are higher than those produced on the hammer. High productivity; Less metal loss; Hammer forging die is composed of two parts of the upper and lower die, horizontal machine is composed of punch and by two half of the composite of a total of three parts of...Read more -
What are the uses of forgings?
Forgings are workpiece or blank obtained by forging deformation of metal billets. The mechanical properties of metal billets can be changed by applying pressure to produce plastic deformation. Forgings can be divided into cold forging warm forging and hot forging according to the temperature of t...Read more -
Forging stamping production technology characteristics
Stamping is one of the basic methods of metal plastic processing. It is mainly used for processing sheet forgings, so it is often called sheet stamping. Because this method is carried out at room temperature, it is also called cold stamping. Although the above two names are not very precise stamp...Read more -
How to identify the quality of forging
