How to distinguish the quality of the roof sheet roll forming machine intuitively?
Aug 06, 2018

For roof sheet manufacturers, it’s very important to choose the good roof sheet roll forming machines. Bought the good ones, then you can make the smooth production. How to buy the good roof sheet roll forming machines? We should know How to distinguish the quality of the roof sheet roll forming machine intuitively.

 

How to judge the roof sheet roll forming machine’s quality is good or bad, we can simply check the quality from the following main steps: 

 

Firstly, Check the machine frame. For example, watch the lacquering color. Check the material of the I-beam and plate. Check if machine fixed the good quality and high strength screws. Whether equipped the good electrical control system. The electric appliance is very important, because every production process will be controlled and finished by it. In addition, the raw materials determine whether the roof sheet roll forming machine is durable and has the long service time. 

 

Then, check the shaft’s quality. Are they solid or hollow? Because, the roof sheet’s quality depends on the roof sheet roll forming machine’s quality. Shafts are very important during the roll forming process. There are two kinds of shafts, Solid and Hollow. Solid shaft has the bigger  pressure, so, the roof sheet will have the better precision. Contrary, the hollow shaft’s extrusion pressure is small, so the roof sheet’s quality will not as good as the roof sheet which are produced by solid shafts. So, we must check the shafts are solid or hollow. The method is very easy, discharge one or two shafts randomly to check.   

 

Then, check the vertical plate’s size and thickness. Check the wheels’ material and sizes. Check the size of the driving chains. These can judge the roof sheet roll forming machine’s quality is good or bad intuitively.
