About this machine
TPS S8900 Automatic Channel Letter Bending Machine
TPS S8900 is the precision machine in the range, a full upgrade of the earlier S8710. Closed-loop control, pneumatic clamping and a double lead-screw alternate feed replace the belt drive, which raises feeding torque and keeps the strip from creeping under load — the two things that decide whether a tall letter closes cleanly.
A servo-driven V-groove slotter with adjustable depth and the telescopic alternating bending bars handle heavier gauges and taller profiles than an entry-level bender can. Side hole punching is available as an option and is done in the same pass, which removes a separate drilling step when the back plate has to be fixed.
It is the machine for high-grade landscape LED letters, stainless steel letters, punched letters and resin letters where the finish is judged close up.
Applications
- High-grade illuminated LED letters for facades, malls and commercial buildings
- Tall stainless steel and galvanised lettering up to 175 mm
- Punched letters with side holes for back-plate fixing
- Resin-filled and decorative branding letters
- Landscape and architectural signage

Frequently asked questions
What is the S8900 built for?
High-grade lettering where the finish is judged close up: illuminated LED letters for facades, malls and commercial buildings, tall stainless steel and galvanised letters up to 175 mm, punched letters with side holes for back-plate fixing, resin-filled and decorative branding letters, and landscape and architectural signage.
Which materials and letter heights does it handle?
Stainless steel, galvanised sheet and aluminium coil from 0.6 to 1.0 mm, at a processing height of 20 – 175 mm. An optional bending die takes aluminium from 1.0 to 2.0 mm.
Why does the feeding system matter on tall letters?
The S8900 feeds with a double lead screw instead of a belt. That raises feeding torque and stops the strip from creeping under load, which decides whether a tall letter closes cleanly. Four axes are driven by three servo motors and one stepper motor under closed-loop control, with pneumatic clamping.
How is the strip slotted and bent?
A servo-driven V-groove slotter with adjustable depth and telescopic alternating bending bars handle heavier gauges and taller profiles. The minimum bending radius is R7 mm, the minimum distance between interior and exterior angles 3 mm, and bending starts 3 mm from the strip end.
Can it punch holes for the back plate?
Yes, as an option. Side hole punching is done in the same pass as bending, which removes a separate drilling step when the back plate has to be fixed. Tell us if you need it and we will include it in the quote.
Which files does it take?
DXF and PLT, so you work from the files you already draw in AutoCAD, Type3, CorelDRAW or Adobe Illustrator. The machine runs closed-loop servo control with TPS in-house channel letter bending software.
What does it need on site?
An AC 220 V, 50 Hz supply for 2.5 kW installed power, compressed air at 0.4 – 0.6 MPa, and floor space for 1450 × 820 × 1550 mm. It weighs 600 kg net and 680 kg gross.
