SuNPe has own sheet matal factory which can support projects from simple bent sheet metal prototypes to complex mechanical assemblies.

The materials commonly used in sheet metal processing are cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC、SGCC), copper (CU) brass, aluminum plate like AL5052, stainless steel (mirror/polished, brushing surface, frosted surface).

According to the difference of sheet metal structure, the process flow can be different steps as below:

1.Laser cutting is to use laser cutting method to cut out the structural shape of the plate on a large plate. Like CNC cutting material, laser program should be written. It can be used for various complex shape flat parts with low cost and precision of 0.1mm

2.Flanging: also known as pumping hole, flanging hole, is to make a slightly larger hole on a smaller base hole, re-tapping, mainly using thin plate, increase its strength and number of threads, avoid sliding teeth, its hole around normal shallow flanging, the thickness is basically unchanged.

3.Punching:the general punching machine has punching, cutting angle, blanking, punching bump (bump), punching tear, pumping hole, forming etc processing methods, it needs to have the corresponding die to complete the operation, the operation mainly pay attention to the position, direction.

4.Pressure riveting: there are mainly pressure riveting nuts, screws, bolt and so on, it is through the hydraulic pressure riveting machine or punching machine to do.

5.Bending: bending is to fold 2D of flat parts into 3D of parts. We usually make bending die to complete it.

6.Welding: argon arc welding is common used in welding process, weld two or more parts together to achieve the purpose of assembly finished products, or the edge seam of a single part needs to be welded to make the bending edge precise to increase the folding strength.

7.Assembly:we also have assembly workshop to support from prototyping to low volume production. Assemble the whole product to help our customer make their design to be real.
