Roll Form Design. Most roll forming companies want to produce the most cost-effective and highest quality products. The number one way to accomplish this is to have the best roll forming design. We at Roll-Kraft are well aware of the complexities, when designing your roll form tooling.
Aug 08, 2006· While the first step in successful punching is to pay close attention to the quality and features of punching tooling, other factors come into play. Punched slugs are clues, and examining them can reveal whether the punch and die clearance is too loose or too tight and whether the machine is properly aligned.
Now we know why roll hardness is important. Next let's discuss how to achieve and measure roll hardness. As a roll of flexible packaging film material winds, tension builds inside the roll, which is known as in-wound tension or residual stress. If this stress becomes greater as the roll is wound, then the inner wraps towards the core will be put

Jan 31, 2002· Using a thin-wall or ultrathin-wall mandrel in place of a standard-wall mandrel is not recommended. Thin-wall and ultrathin-wall mandrels typically are weaker by design, and attempting to bend a tube with a heavier wall likely will break the mandrel. Mandrel Placement. Proper placement of the mandrel is critical.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

A good preventive maintenance program can help to keep your mill in top condition, but even so, an annual checkup with an alignment is a good idea.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Tube and Pipe Roll Tooling Design. If you want to produce the best and most cost effective tube and pipe, you need the best tooling design. Most tube and pipe producing companies know that if the roll tooling design is not correct, you will experience increased scrap due to marking, difficult setups, welding and other formation problems.
Tube roll design begins with the selection of the most appropriate breakdown roll forming type for the application. Then a sequence of shapes representing the desired amount of bending at each mill station is developed. When we stack these shapes on top of each other they look like a flower. Hence the term, "Forming Flower".
Tube roll design is an organized process culminating in the production of a roll formed welded metal tube. First consideration is the products' specific characteristics of size, shape and physical properties. The next consideration is the forming and welding machinery available to the producer.
