Brief introduction for cold roll forming process

General cold roll forming process: single sheet forming, forming and continuous forming, combined molding.
 
1. Single sheet forming
The sheet forming process is to cut the plate into the specified length beforehand, and then the sheet is fed into the forming machine by selecting the material roller. After rolling the profile can be directly collected into the storage, especially for sheet metal forming after cutting easy deformation of products, used for small batch production.
 
The utility model has the advantages of simple equipment, low investment and small footprint.
 
2, roll forming and continuous molding
The process of forming and continuous forming is basically the same, and their different points are: the continuous forming of the plate connection must be welded to make the sheet continuous molding process, and the roll forming is a single volume supply.
 
Most of our roll forming machines use this method.The decoiler is to unfold PPGI or GI,and then feed it into the main forming machine. The working speed is more faster than Single sheet forming. For some high speed production such as high frequency pipe welded machine. There is an accumulator for continuous feeding. 

3. Combined Molding
The combined molding process is the molding process of special steel, the section steel has special requirements for forming process, and it needs complex forming equipment, which is suitable for the processing of high-strength sheet. Complex equipment requirements, high investment.
