Rolling Form Technology can Creat More Benefits
As is evident from the coverage of developments in body design and engineering elsewhere in this issue, designers are coming up with edgier body panels. Many of these designs, when applied to closure panels, can be troublesome when it comes to hemming. To address this problem, engineers at Lamb Techicon Body & Assembly Systems recommend the use of roll forming. According to its Dan Stiers, vice president of Business Development, roll forming permits rolling back panel flanges that have an angle of 105 or more back to 90: to a position that is hemmable.
The process of roll forming is a continuous operation wherein a long metal strip /coiled steel is allowed to pass through consecutive sets of rolls at a room temperature. Each set of rolls perform the required incremental parts of the bend till the desired cross section of the metal strip is achieved.
The Roll forming technology combines many of the secondary metal forming operations like welding, stamping and this reduces the individual machineries’ operational installation and capital costs. Roll forming creates typically products with superior surface finishes, meeting the consistent uniformity and dimensional tolerances. Material gauges of merely. 010 inches to 1.00 inches thick can be just pressed into the required cross section and it is later cut into the required design and size order of the manufacturer.
The installation of the roll form machinery is not very expensive but it requires latest machinery installation and trouble solving knowledge. There are many online classes and workshops which train technicians, Engineers to follow a systemic approach to solve the day today issues and problems during the installation of these roll out machinery. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like belt conveyor, Henan Hongxing is always doing the best in products and service.
Apart from pointing out the features if one compares it with the Extrusions the undeniable advantage of the Roll form machine’s efficiency can be noted. Roll forming can combine embossing, punching as well as contouring to add up value and reduce machine costs but extrusion and its application is limited and its draw backs are evidently visible when the sheet/metal strip which is induced to extrusion is checked for flaws.
The other steel sent through roll forming presses for buildings is galvanized steel. Galvanized steel is an inexpensive and effective steel used in a wide variety of applications. It is used in steel frame houses, cars, roofing and it can be reused and recycled multiple times. Galvanized steel is also corrosive resistant. It goes through a chemical process where the steel gets coated with layers of zinc. A key factor with zinc is that rust won’t attack zinc. What makes the galvanized steel so effective is that the chemical reaction in the alloying process permanently bonds the zinc to the steel, that’s what galvanizing means. It is an electrochemical process named after Luigi Galvani, an Italian scientist.
You will find galvanized steel being used in a wide variety of uses, one of which is Purlin roll forming. You will find it on roofs, on siding, drain pipes and many more applications. It is inexpensive and much more durable than most other materials used for building. It can be painted and comes in a variety of different looks for your housing material needs.
