Plate metal technological processing might be a bit different, but mostly it is as the following.

Designing and drawing of plate metal pieces

It is known as triple viewed drawing and expresses plate pieces structure through a draw.

Draw the extension scheme.

This extends contricate structured pieces into a smooth part.


Blanking means may vary. Mostly they are as the followings:

  1. Shear blanking makes possible to cut the extended diagram breadth and length. In case of punching or corner notching, punch device merged with die is suitable.
  2. Punching blank.

Sheet form is shaped in the aftermath of piece parts extension through pressing in a single stage or multiple ones. It is advantagous with quick operation, effectiveness and low operation costs. It has a wide application in mass manufactury.

  1. NC blanking.

This has to be programmed. A software adopted by the device writes extended diagram and cuts out the required piece out of smooth plate in accordance with program.

  1. Laser blank implies obtaining the required form out of flat sheet through a laser.

Flange tapping.

This is also known as perforation and implies drawing a bigger hole on a less basis one and tapping in the hole. It increases force and makes possible to escape screw loosing. If the seet is of 2-2.5 mm a direct tap is possible and with no needto turn it over.

Punching Fabrication

Punch manufacture mainly implies hole punching, edge notching, blanking, convex frame punching, hole drawing and so on. Appropriate molds are needed to accomplish a certain operation. Convex frame punching is realized through a convex mold, tear punching is done by tear shaping die.


Pressure revet pins, screws and bolts are used by factories. Plate metal pieces are commonly riveted through a punch device or hydraulic revet device.

Bend process

Most commonly this implies foling 2 D pieces into 3 D ones. This process demands a press brake as well as appropriate bend dies to accomplish the process. There is a particular folding principle, which implies first folding the spot that does not interfere punching die immediately, later folding the areas where interference exists.

See Press Brake Ultimate Guide for a whole perception on press brakes.

Weld process

This process makes possible to obtain the ultimate manufacture requirements through welding different pieces or one piece seam welding for force increase.

This system involves such weldings as CO2 shielded, argon arc, spot or robot weldings.

Which of these weldings to choose depends on fabriaction demands and material composition. Mainly CO2 gas shield weld is suitable while welding iron sheet. Argon arc is used while welding aluminum sheet. In case of large work piece, long welding seam, for instance cabinet weld process robot weld is suitable. It shortens operation steps and provides top weld outcome.

Face processing

Face processing has got a phosphate slick, electro-plating colour zinc, chromated salt, oxidization, etc. The phosphate slick is applied while realizing cold roll. It coats plate stuff with a defence layer to escape oxidization. Next one functions to enhance paint adherence. Electro-plating colour zinc is suitable for cold roll plate face processing. Chrom and oxidization are applied in aluminum stuff face processing. Face processing technique selection depends on customers`demandings.
