Our sheet metal fabrication facility, along with a team of experienced engineers, ensures that each part is manufactured to precise specifications and quality standards.
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.

Delivery
We stock a variety of metal materials suitable for various part applications and industries. Available materials include aluminum, brass, stainless steel and steel alloy for metal parts.
Cold-rolled sheet SPCC is mainly used for electroplating and baking varnish, which is low in cost, easy to form, and has a material thickness of ≤3.2mm.
Hot-rolled sheet SHCC, material T≥3.0mm, is also made of electroplating and baking varnish parts, which is low in cost, but difficult to form, mainly flat parts.
SECC electrolytic plates are divided into N material and P material. N material is mainly not used for surface treatment, which has high cost, and P material is used for sprayed parts.
It is mainly used as conductive material, and its surface treatment is nickel plating, chrome plating, or no treatment, and the cost is high.
Aluminum plate generally use surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
Aluminum profiles materials with complex cross-sectional structures, which are widely used in various sub-boxes. The surface treatment is the same as that of the aluminum plate.
Stainless steel is mainly used without any surface treatment, and the cost is high.
Enhance part performance by selecting surface finishes that improve the roughness, hardness, chemical resistance, and cosmetic features of the finished component.

According to the difference in the structure of sheet metal parts, the process flow can be different, but the total does not exceed the following points.
Cutting ; Fitter ; Flanging ; Punching machine ; Pressure riveting ; Bending ; Welding
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.
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.
