Laser cutting

Laser Cutting

Laser cutting utilizes a high-energy laser beam to cut materials into desired shapes. 



Bending is accomplished by positioning the metal sheet on a bending machine and applying pressure to shape it as desired. 



Welding involves heating the metal to its melting point and using appropriate welding materials to join metal components together.

Sheet Metal Fabrication Overview

What is Sheet Metal?

Sheet metal is a process for thin metal sheets (usually below 6mm), including bending, punching/cutting/compositing, folding, welding, riveting, splicing, forming (such as automobile body, computer body), etc. Its remarkable feature is that the thickness of the same part is consistent. Products processed by sheet metal technology are called sheet metal parts.

Why Choose PROTO MFG
for Sheet Metal Fabrication?

1. High production and processing efficiency


2. Remarkable results

The cutting in PROTO MFG sheet metal processing is non-contact laser cutting, and the outer edge heating has little interference, which can avoid the adverse effect of thermal expansion on the product workpiece. It can suppress the collapsed outer edge caused by laser cutting of raw materials, and generally does not need to be processed again, which improves the work efficiency to a certain extent.


3. Not limited by material properties

The state-of-the-art equipment of PROTO MFG enables sheet metal processing to quickly produce aluminum profiles and carbide, regardless of hardness, which can be laser cut without distortion. The production and processing flexibility is also very good, not only can handle any graphics but also can cut pipelines and other various materials. Most non-metallic materials can also be processed quickly and efficiently.
