Pipe Cutting

There are four main methods of pipe cutting: cutting, silver cutting, turning cutting, punching cutting, metal lathe cutting parts of the end of the machining precision is relatively high.

It is generally used for machining parts of pipes that need to use capacitive energy storage welding, with high production efficiency of punching, but the punch is easy to shrink, and its application area is relatively narrow.

Bending pipe is generally used in the bracket structure, bending pipe technology refers to the special machine tool, with the help
of special equipment to bend the pipe into a circular arc processing technology.

Bend pipe is generally divided into hot bend and cold bend.Hot bending is used for pipe with thick wall or solid core, but it is seldom used in metal furniture.Cold bending is formed by bending pressure at room temperature. The commonly used pressure methods include mechanical pressure, hydraulic pressure, manual pressure, etc.

Drilling and punching

General metal parts with screws or rivets combined, the parts must be perforated or punched.

Drilling tools generally use bench drill, vertical drill and hand electric drill, sometimes in the design will also be used slot.


Common welding methods include
gas welding, electric welding, energy storage welding and so on.After welding, welding nodules must be removed to make the surface of the pipe smooth.

Surface treatment

The surface of the parts should be electroplated or coated. There are two kinds of coating methods: spraying metallic paint and electrophoresis paint.

Assembly of components.

After the final correction, the parts are assembled into products with screws and rivets according to different connection modes.
