Automatic Channel Letter Bender for SS/Iron/Aluminum Letters

Model VAM-S5 Automatic Channel Letter Bender Machine is Comprehensive upgrade on the basis of model VAM-S3, it is the hot option for bending stainless steel letters, both flat aluminum and profile channel letters. Meanwhile, the feeding, slotting, bending, height adjustment, all controlled by Delta A2 servo drivers, in addition, the pneumatic components are all upgraded to Japan’s SMC brand.


1. Material pre-straightening System of automatic channel letter bender is to avoid the material stuck during processing.

2. Double Servo and ball screw system, more stable and more accurate.

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

4. Exchangeable planer tool for ss, iron and milling cutter blade for flat aluminum.

5. The telescopic bending system can greatly reduce bending scratch which is capable of making letters with small angles and complex graphics.

Material Pre-straightening System

The multi-axis material pre-straightening system of automatic channel letter bender is to avoid deformation of the coil while feeding, thus the coil won’t be stuck in processing. Free Adjustable for different thicknesses of material.

Circulating Alternating Feeding System

Alternating Clamping Feeding system, which is 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.

S5 slotting

Double Slotting System

Exchangeable planer tool (for stainless steel, iron) and milling cutter blade (for aluminum and profile), it use 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. 

The aluminum profile adopts a DC motor drive alloy milling cutter blade, what’s more, it is equipped with a high-quality ball screw and linear guide, consequently, it is to ensure the slotting smooth and flat.

Telescopic Bending System

The telescopic bending system can greatly reduce bending scratch which is capable of making letters with small angles and complex graphics. 

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.

Self-developed Software System

The software system of automatic channel letter bender machine is developed based on years of industry experience and customer feedback.

For instance, the professional design of a variety of practical functions for different models, moreover, the English interface of software is simple and user friendly, easy to learn and operate.
