A guide to help choose the best sheet metal fabrications company
The technological capability and experience of a fabricator determines the outcome of the product. There are many fab-shops but very few are equipped with the technology to carry out precise metal fabrication works. For work on large sections of metal, a sophisticated assembly line that can convey and hold metal in place while being worked on makes fabrication process conforms to exact draft specifications. The process involves cutting, bending and assembly. A reputed fabricator will have capabilities to handle large contracts easily. Each of these stages would be modularized in his fabrication unit. Before you opt for a fabricator it is worth to spend time on investigating the technological sophistication.
Laser cutting
CNC cutters are able to cut carbon steel, stainless steel and aluminum easily. A high powered laser is directed by a computer on the metal surface. Depending on the method, the material vaporizes melts or cracks leaving a fine edge. The processes produce high accuracy cuts and the edges are devoid of even microscopic protrusions.
Such precision is desired for industrial applications as sheet metal after bending, is assembled with other parts before the final product takes shape. Without high accuracy cutting, the metal could undergo changes in dimensions on constant use and affect the functioning of the manufactured product. When compared to mechanical process, these process offers increased accuracy, speed and also ensures a cleaner workplace.
Using Press Brake to make predetermined bends
Press Brake Forming, as the process is commonly called, is indispensable in manufacturing. The metal rests on a die of desired shape and a matching punch from above creates a bend to make the metal conform the metal at the point of impact to the shape of the die. There are many types of dies available. Some commonly used die shapes are V-dies, offset dies, channel forming dies, 90-degree dies and acute angle dies. A set tonnage number determines the force exerted, which can further be controlled. The presses themselves are classified depending on their drive mechanism. Pneumatic and hydraulic are commonly used drive technologies. Servo-electric drive mechanism allows for correction during pressing, which may translate into higher efficiency.
Tube bending techniques
Freeform Tube bending is one of kind where metal is bent without the aid of a die. Such a process is useful for making multiple bends of piped metal. Besides round stock, rectangular or square stock can also be bent through this process. The degree of bend is controlled by the drive technology and the placement of the tube itself. There are many methods but those used in large fab shops include heat induction and roll benders.
