Sheet metal LASER CUTTING AND bending FABRICATION
What is Sheet Metal cutting and Bending Fabrication?
Sheet metal cutting and bending process is a fabrication forming process to overcome the metal sheet tensile stresses and compressive stresses getting a desired geometric working piece formed via the bending process. this sheet metal bending process will not change the material thickness, weight and properties. it is an cost effective way for big metal frames and parts manufacturing .
The metal sheet materials options are Aluminum sheet metal, Copper sheet metal and Stainless steel sheet metal. depend on different material will have different post finish treatments. the Sheet Metal process including bending, laser cutting, punches, welding, riveting and other prototyping process.
SHEET METAL bending PROTOTYPes AND LOW VOLUME PRODUCTION
What is the Application of Sheet Metal Bending process?
Sheet metal bending process is normally use applied for Prototypes, low volume production to medium volume production and even mass production. It is a flexible solution for filters, panels, frames, housings, enclosures, shells and cabinets apply in medical, defense and aerospace industrial area. Sheet metal bending process is a 3D forming process includes bending, fording, laser cutting, punches, welding, riveting and other prototype working and finishing processes.
How Sheet Metal Bending process works?
Sheet Metal bending is a thin, flat and even metal sheet piece formed by a metal working process to get cut and bent into a variety of shapes. Thicknesses are varied significantly between the soft metal sheet material like Aluminum sheet and copper sheet, and the hard structural metal sheet like stainless steel sheet. Sheet metal bending shows that the more thickness it has, the harder processing it will be for bending; and the less tensile stresses it has during bending, the more easier for material crack it will be.
What is the material options for Sheet Metal Bending?
The common sheet metal bending materials in prototyping and manufacturing are the SGCC, pure copper sheet, soft aluminum Sheet AL5052 and Stainless steel AISI 300 series sheet. Beside the above, other series of above material are in less tensile that parts joint edge of the sheet metal will get crack or even break during bending.
At the same time, The thickness is a factor to consider for sheet metal bending, which the more material thickness the sheet has, the bigger bend radius it will be for both inside and out; and if it is too thick, it will be hard to bend. For sheet metal bending, all the thickness of the material sheet in the exist market are given and all the tolerance of the material sheet are aslo given.
As for sheet metal bending post finish, beside the SGCC which is already with a plating film exist, All the others can apply the finish treatment such as brushing, Aluminum anodizing, powder coating, laser engraving, silk screaming and so on. Rivet studs, nuts, bolts is the most common inserts for the assembly position and use of the sheet metal bending products.
Comparation of sheet metal bensing and PLASTIC sheet bendin
What is the difference between Sheet Metal bending process and Plastic Sheet Bending process?
The advantage of sheet metal bending processing is quick and inexpensive for new products manufacturing from one prototype to volume production. Is it possbile to get the plastic sheet bending too? in Sandi rapid made company, the answer is Yes.
Beside sheet metal bending, plastic sheet bending is also a cost effective process for less structure shells and cover parts. The process is depend on the part design without uneven thickness structure like metal sheet material. the plastic sheet bending process normally is heat bending, material options are any sheet in clear or opquoe plastic, with or without surface treatment.
