Skills Of Precision Sheet Metal

The skills of precision sheet metal processing mainly include the following aspects:

Surface treatment: The use of surface treatment technologies such as epoxy asphalt, chlorinated rubber, acrylic polyurethane, and fluorocarbon can effectively improve the corrosion resistance of metal products and resist the erosion of the external environment.
Bottom treatment: Remove the rust on the bottom of the sheet metal shell through special treatment to ensure that the bottom does not rust, thereby extending the overall service life.

Use epoxy zinc-rich paint: Epoxy zinc-rich paint is composed of epoxy resin, epoxy curing agent, zinc powder, anti-rust pigment, additives and organic solvents. It has good material properties and easy spraying, and can effectively prevent rust.

Corrosion-resistant coating: The use of a coating made of epoxy mica iron oxide can provide a long-term corrosion-resistant coating and improve the sealing performance and corrosion resistance of the composite coating.

Sheet metal design skills:

Cutting shape: Increase the artistic sense of the design through exquisite cutting.
Bending design: Reduce the indifference of the design, but may increase the processing cost.
Wrapping stacking: Create a rich sense of hierarchy through surface stacking.
Cutting: Often used in combination with stacking to achieve better visual effects.
Line color blocks: Use colors and lines to enhance the impact of the design.
Detail processing: Enhance the beauty of product details through lighting effects, silk screen printing, CMF processing (such as brushing, frosting, etc.).

Sheet metal process:
Shearing: Cut metal sheets into the required shape through a shearing machine.
Blanking: Use laser cutting or CNC punching to accurately cut the workpiece.
Blanking: Use ordinary punching machines or other equipment to process the product shape through molds.
Punching: Process various small holes through molds, such as screw holes, rivet holes, etc.
Bending: Bend the workpiece into various shapes through a bending machine.
Forming: Use a mold to deform the workpiece to the desired shape.
Punching: The process of forming a round hole edge on the workpiece through a mold.
Expansion: Use a drill or milling cutter to process a small hole into a large hole.
Countersinking: Process a tapered hole to fit countersunk screws and other fasteners.
Pressure riveting and expansion riveting: Use a punch or hydraulic press to firmly press fasteners such as pressure rivet nuts and expansion rivet nuts onto the workpiece.
