Take you to know the sheet metal working procedure

1. Shearing: refers to the technological process in which the material passes through the shearing machine to obtain the rectangular workpiece.

2. Blanking: refers to the process in which the workpiece is cut by LASER or punched by CNC punch.

3. Blanking: refers to the process of obtaining the product shape by using dies on ordinary punches or other equipment.

4. Punching: refers to the process in which the workpiece is processed by a common punch and die.

5. Bending: refers to the process in which the workpiece is shaped by a bender.

6. Forming: refers to the process in which the workpiece is deformed by using a die on a common punch or other equipment.

7. Punching: Also known as "flanging", refers to the process of turning the round hole edge over the workpiece by using a die on a common punch or other equipment.

8. Tapping: refers to the process of machining the internal thread on the workpiece.

9. Reaming: refers to the process of machining small holes into large holes on the workpiece with a drill or milling cutter.

10. Countersunk hole: refers to the process of machining tapered holes on the workpiece to fit the connection parts like countersunk screw.

11. Pressing riveting: refers to the process of firmly pressing fasteners such as pressure rivet nuts, pressure rivet screws or pressure rivet nut studs onto the work piece with a punch or oil press.

Riveting: refers to the process of first countersunking the workpiece, then firmly pressing the riveting nut on the workpiece with a punch or oil press.

13. Nut pulling: refers to the process similar to riveting.The process of securely attaching a connection, such as a rivet nut (POP), to a work piece with a puller gun.

14. Pulling riveting: refers to the process in which two or more workpieces are joined together tightly with a pulling riveting gun as a tool.

15. Riveting: The process of connecting two or more workpieces face to face with rivets. If riveting the countersunk head, the workpiece should be countersunk first.

16. Punching convex lug: refers to the process of forming a convex shape of a workpiece with a die on a punch or oil press.

17. Punching tear: Also known as "punching bridge", refers to the process of forming a bridge-like shape of a workpiece with a die in a punch or oil press.

18. Imprinting: refers to the process of punching out words, symbols or other imprints on a work piece using a die.

19. Angle cutting: refers to the process of cutting the workpiece angle by means of a die on a punch or oil press.

20. Punching hole: refers to punching the workpiece with a die on a common or CNC punch.

21. Flattening: refers to the process of transitioning a shaped workpiece to flattening.

22. Drilling: refers to the process of drilling the workpiece on a drill or milling machine with a drill bit.

23. Chamfering: refers to the process of machining sharp corners of workpieces by means of dies, files, grinders, etc.

24. Leveling: refers to the process of leveling the workpiece before and after machining, using other equipment.

25. Back teeth: refers to the process of repairing the second screw teeth on the pre-tapped workpiece.

26. Affixing protective film: refers to the process of using film to protect the surface of workpiece.

27. Tear protective film: refers to the cleaning process of protective film on workpiece surface.

28. Alignment: refers to the process of adjusting the processed workpiece.

29. Heat shrinkage: refers to the process of using heating equipment (hot air gun, oven) to tighten the plastic covering the workpiece.

30. Labeling: refers to the process of sticking labels to specified positions of workpieces.
