Super Channel Letter Bender Machine for Outdoor Giant Letters

Model VAM-S40 Stainless steel/aluminum Channel Letter Bender Machine is also called Industrial Grade automatic letter bender. The bending force, bending height and thickness perfectly improved, it is capable of bending stainless steel strips height up to 400mm (16”) and thickness 3.0mm (.118”). Specially designed large size active material feeding support, it is the first choice for making landscape letters, square letters and outdoor giant 3D sign letters.


1. Delta A2 series Servo and ball screw system, more powerful for high and thick coil strips.

2. Clamping alternating feeding system and closed-loop control System, perfectly matching with panel letter.

3. Ball screw notching system with cooling sprayer which is more humanized for higher efficiency.

4. The telescopic bending system can greatly reduce bending scratch which is capable for making letters with small angle and complex graphics.

Imported Servo Driver System​

Adopt imported brand 1500 watts servo motor and high-quality reducer, as well as 3 pieces of servo motor drivers provide large power, consequently to ensure bending strength for processing thicker materials of super 3D channel letters production.

Circulating Alternating Feeding System

Alternating Clamping Feeding system, greatly reduced the waste of materials. Designed by two sets of fixture clamping material circulating feeding, it is aim to eliminate the phenomenon of feeding slip. 

Servo drive and high-quality ball screw, moreover, the Linear guide configuration makes the feeding smooth, in other words, the material deformation can be effectively controlled. Most importantly, the length encoder and the system composed of a Closed-loop control system to ensure the finished channel letetrs and the source file perfectly matched.

S40 Imported Slotting System​

Imported Slotting System

High quality planer tool with air cooling system specially for large stainless steel, iron and aluminum plates.

CNC lathe knife as a slotting tool of German imported carbide knife, that is to say, it is high strength and low loss, double-sided with 8 flutes, as a result, it is time-saving and without sharpening. 

Telescopic Bending System

The telescopic bending system is made of nodular cast iron which has good shock absorption and high structural strength. Likewise, the number of parts spliced reduced, therefore, the bending structure never deforms, the positioning accuracy and bending stability effectively improved

The bending part adopts the servo drive control, so through the adjustment of servo linear, the rigidity and the torque, even the bending radian and the speed are in perfect control. In conclusion, the finished channel letters match accurately with laser cutting machines, plasma machines, and engraving machines, etc.
