Process of custom metal fabrication Toronto
Custom metal fabrication requires a good number of manufacturing tools and machines that can perform the function of bending, rolling, cutting and the combination of metal into complex sizes and shapes. In the finishing processes of custom metal fabrication Toronto, the tasks will include adhesive sawing, screwing, riveting, grinding, deburring, bolting, bonding and painting. In the search for custom metal fabrication Toronto, it is important that the fabricator has as many features available in one roof.
Sheet metal bending
The bending of sheet metal is a common process in custom metal fabrication Toronto. Sheet metal bending is the plastic deformation of a workpiece over an axis to create a change in the part’s geometry. The shape of sheet metal may change but its volume remains the same; however, in some cases, bending may produce a slight change in the sheet metal’s thickness. In addition to creating a desired geometric form, bending can also impart strength and stiffness to sheet metal.
A large majority of metal products used today have undergone the process of metal rolling which is the creation of raw metal forms. Ingot or continuous casting is hot rolled into a bloom or a slab which are the basic structures in the creation of a wide range of manufactured forms. At a rolling mill, blooms and slabs are further rolled down to intermediate plates, sheets, strips, coil, billets, bars and rods which are the starting materials for subsequent manufacturing operations like forging, steel metal working, machining and custom metal fabrication.
Most cutting processes in custom metal fabrication Toronto are performed through the application of shearing forces to separate the material; however, other removal processes can be applied using heat or abrasion. Cutting with shear includes shearing, blanking and punching while cutting without shear forces include laser beam cutting, plasma cutting and water jet cutting.
Laser beam cutting – where a focused laser beam is directed at a material that either melts, burns, vaporizes away or is blown away by a jet of gas leaving an edge that has high quality surface finish. Industrial laser beam cutters are used in cutting flat sheet metal as well as piping and structural metals in custom metal fabrication Toronto.
Plasma cutting – is a process used to cut steel or metal of different thicknesses using a plasma torch. An inert gas is blown at high speed out of a nozzle at the same time that an electrical arc is formed through the gas from the nozzle to the surface being cut, turning some of the gas to plasma that will melt the material being cut.
Water jet cutting – uses a very high pressure of water or a mixture of water and an abrasive substance to cut hard materials like metal or granite.
