What is the effect of thick rubbing on forging process?
Friction in forging is the friction between two metals of different composition and properties (alloys), between soft metal (workpiece) and hard metal (die). In the case of no lubrication, is the contact friction of two kinds of metal surface oxide film; Under the lubrication condition, the conta...Read more -

What kind of shaft forgings meet the requirements?
Axial forging is a kind of wide application of forgings, such as axial plus has good processability, m any porosity in practice, there is no other flaws, thus not only has good appearance, with fine, here is how to introduce you to conform to the requirements of axial forgings to be popular. Firs...Read more -
The sealing method of hydraulic cylinder forging
The reason why the hydraulic cylinder forgings need to be sealed is because of the existence of internal leakage and external leakage. When there is internal leakage and external leakage in the hydraulic cylinder, it will lead to the volume of the hydraulic cylinder's cavity and the efficiency wi...Read more -
What forging technology does the flange factory have?
Flange factory is a production enterprise producing flanges. Flanges are parts connected between pipes, which are used for the connection between pipe ends. It is also useful for the flange on the inlet and outlet of the equipment for the connection between two devices. The production technology ...Read more -
How to forge stainless steel forgings?
The precision of rough or stainless steel forgings is higher. The application of advanced technology and equipment can achieve little or no cutting. The metal materials used in forging should have good plasticity, so that under the action of external force, plastic deformation can be produced wit...Read more -
The sealing principle and characteristics of flange
Sealing of flat-welded flanges has always been a hot issue related to the production cost or economic benefit of enterprises. However, the main design disadvantage of flat-welded flanges is that they are not leakproof. This is a design flaw: the connection is dynamic, and periodic loads, such as ...Read more -
What should be noted in the examination of die forgings before heat treatment?
The inspection before solution heat treatment is a pre-inspection procedure to check the finished product's surface quality and dimensions according to the technical conditions, die forging drawing and process card after the forging forming process is finished. Specific inspection should pay atte...Read more -

What is the process of forging?
1. Isothermal forging is to keep the temperature of billet constant during the whole forming process. Isothermal forging is used to take advantage of the high plasticity of certain metals at constant temperature or to obtain specific structures and properties. Isothermal forging requires the mold...Read more -
The main disadvantages of water as a quenching cooling medium for forgings ？
1) in the austenite isothermal transformation diagram of the typical area, that is, about 500-600℃, water in the steam film stage, the cooling rate is not fast enough, often cause uneven cooling and insufficient cooling speed forgings and the formation of the "soft point".In the martensite transf...Read more -
