Forging and Deep Drawing
Forging is the process of shaping metal or metal alloys by hammering, pressing, or rolling them into shape with great pressure. This process can be done with manual tools, with a power hammer, or with a hydraulic press. While the process has been around since ancient time......

Roll Groove forming and Its Applications
Roll groove forming is a steel processing method used to produce roll grooves, which are found in a wide variety of applications. Roll grooves are used to form spiral helical, or straight channels in long, ductile material such as steel or aluminum. Roll g......
Multiple roll pass rolling
Introduction
Rolling mills are essential components in many metal forming processes. While typically used in the manufacturing of steel products, rolling mills can also be used to roll other materials such as aluminum or copper. The process of shaping a workpiece by repeatedly rolling it through ......
Reasons for fluctuations in the finished product size of the continuous rolling mill
Reasons for Fluctuation of Product Size in Rolling Mill
Rolling mill is an important equipment in the industrial sector and is used to reduce the thickness of steel or other metals. The efficient operation of a rolling mill is essential for ensuring the quality of the final product. Hence, the si......
variable section rolling
Section Rolling
Section rolling is one of the most common metal forming processes encountered in modern metalworking operations. Section rolling refers to the process of forming rolled steel sections as well as other sections such as angles, channels, I-beams and T-sections. These sections are us......
The basis for judging the quality of roll gap adjustment
Roll Gap Adjustment for Quality Control
Roll gap adjustment is an essential part of roll forming process control and is necessary to maintain the desired quality of the product being rolled. The roll gap is the distance between the two rollers and is the gap in which the strip material is rolled......
Stain marks and injection marks
Stain Stain and Wrinkle Injection
It is common knowledge that fabrics are prone to staining, whether it’s from spilled coffee or some other type of liquid. However, many people don’t realize the importance of immediately cleaning up any type of spill in order to prevent a stain from setting int......
Defects and prevention of lost foam castings - wrinkled skin
Introduction
Castings are often found with subsurface defects attributed to shrinkage. These defects known as “shrinkage porosity”, “shrinkage cavity”, or “cold shut” are located in areas where shrinkage flow of the solidifying metal is impeded due to the geometry of the casting. Shrinkage p......
