What equipment and technology do you need to establish a plastic steel door and window factory?

Plastic steel door and window factory is very simple.

The investment is not big,

The key is that you have a project and the project cost is no problem.

Equipment needs double-headed saw, plastic steel welding machine, layering saw and V-saw. .........

Large equipment. That's enough. Then there are small devices. Those don't cost much.

The technology is simpler. Find a master of plastic steel and solve everything.
