Comparisons of Products

Treatment And ProcessingWe should specially pay attention to the following item when curving, bending, or processing with products：

 

Curving: we should specially pay attention the following three points when curving processing:

 

• Decrease the deckle edge of cutting side as far as possible.
• Clean the trimming and powders.
• Choosing of lubricant: when keep on using, the tools will chafed, asperate the cutting side, decrease the deckle edge, and may caused cracking. To lighten the chafed of tools, therefore, we should use some suitable lubricant.

 

Bending and rolling processing:

 

Bending processing: Because it is a organic film on the pre-painted steel sheet surface, so we should pay attention to the following five items when bending processing

 

• Must clean the scars, pollutions, and rust on the mechanism.
• The interspaces between the punch and die: we should consider that the thickness of the film when setting the interspaces between the punch and die.
• The film may occurred scar, broken and cracked when processing at low temperature, so we should avoid such this environment.

 

Rolling processing：the mechanism performance such as the following：

 

• yield force
• yield point
• work hardening index
• lankford value
• Young's Modulus

 

We should first consider that about material for long size forming, cutting side shape, roll arrangement, roll drive and cutting site then choose the suitable material, so we suggest that serious study about supplier before buying the steel material.

 

Storage

 

• Do not put coils in humid environment, because the capillarity will cause the damp can not volatile normally, easily worsen quality, lower workable years and effect outward
