When change different material, just need to change the bending head and also choose the suitable software for different material.


Equip with rolling feeding material, the built-in closed-loop control system, to realize the closed-loop control of the contour length, make sure to send the feed precision up to 0.1mm


The depth of groove is adjustable, relationship of setting time, convenient regulation processing of different thickness of the material, tool setting more convenient and fast

Linkage type shoot bending mode, the processed products of forming high degree, ultrafast processing.





Materials: Aluminum, stainless steel, iron, galvanized sheetect. See below photo 


Industries: advertising industry, such as logos, signs, other advertising productions.

1. Automatic feeding, open angle 45-135 degrees, automatic bending arc(curved mini diameter 15mm)


2. Fast speed, finish at one time, no need a separate production of acrylic blocks.


3. Controlled by step motor, finish one 30cm letter “S” only takes 44 seconds.


4. Low energy consumption, the total power is 3000W, using power is less than 1500W.


5. Can read DXF,AI, plt vector file format, the same as laser cutting files. Much more convenient to work together with laser machines to finish the whole work of a channel letter.


6. Special need can be customized.


7. It adopts two servo motors that makes feeding and bending speed faster


8. Develop a self-make new software, match with machine working well and make easier process higher precision.


9. The original double-bent knife parallel bending technology, bending angle reached 130 °.


10. High precision machining, feeding precision can reach 0.01mm, bending accuracy up to 0.4 °.
