Metal door frame machine is a kind of roll forming machine which is developed to make various types metal door or window frames, reinforced, fire stop doors, etc by roll forming method. By this one metal door frame roll forming production line, you can finish roll forming, cutting end connection part and others. After roll forming by our production line, we could make very smooth and beautiful metal door frame without any scratch on surface. This metal door frame production line is composed by the following elements: De-coiler, feed & leveling device, main roll forming machine, cutter, run-out table, etc.  Those machines are customized according to the drawing profile of metal door frame.

We can do all kinds of metal door frame,just you send us the profile drawing, we will design the door frame machine according your demand.

The production Process:

De-coiler----Feeding and Leveler---Roll Forming---Cutting Part---Run-out Table

Composition of Metal door frame Roll Forming Machine:

1. De-coiler

Usage: It is used to support the steel coil and uncoil it in a turntable way..Passive uncoil pulled by roll forming system

Loading capacity:1.5T

Uncoiling width:300mm (according to the profile drawing)

Inner diameter450-550mm

2. Feeding and Leveler

Usage: Put the raw material(steel plate) through the beach to manufacture and process,it can guarantee that the products are neat, parallel and everything is uniformity.Please refer to the equipment regulation to know the function of locate angle iron.
