Features
- The Ascent-4AS Channel Letter Bending Machine is fully programmable and calibrated for all materials, with the ability to add new materials easily in the future.
- The machine has all the necessary components, including a coil holder and extrusion holder.
- UL extrusion / profiles are non-proprietary and can be purchased from Ascent at competitive prices or in large quantities directly from the manufacturer.
- Extrusion comes in 1.35", 2", 3", 4", and F-trim sizes.
- Extrusion is painted Epoxy white that can be used without repainting or as an excellent primer for different colors. Other colors are available.
- Ascent's extrusion system uses a pneumatic gun (supplied with the machine) with tiny stainless-steel nails to form the initial shape of the letter, eliminating the need for adhesive. This makes producing letters without trim easier than the competition's system, which uses adhesive and a magnet table.
- The Ascent extrusion system is UL-certified for indoor and outdoor use for letters up to 66" (the competition is only certified up to 48").
- This bending machine accommodates coils of stainless steel, brass, aluminum, galvanized steel, and copper.
- Aluminum coils' height ranges from 1/2" to 8" (203.2 mm), thickness 0.025" to 0.063".
- Ascent equipment is the only bending system in the industry capable of making the smallest letters, with no size limit.
- The Ascent system can produce reverse / halo letters without welding.
- Relatively low-skilled operators can quickly run the machine and perform final assembly after three hours of training.
- Ascent includes installation, start-up, and complete training on the equipment with every machine.
- Separate knife and cutter heads for aluminum and stainless steel (software-driven) — more accurate letters than the competition's lengthy mechanical setup when changing materials.
- Uses 110 VAC / 30 A electrical power and compressed air: cleaner, more efficient operation than systems with an oil pump.
- Critical components made with superior reliability components.
- All recommended adhesives are produced and tested by the largest adhesive manufacturers in the US.
- Adhesive assembly is thoroughly tested at the Ascent Lab in a professional environmental chamber from −20 °C to +80 °C at 80 % humidity.
- Specially formulated Epoxy prevents "yellowing" when exposed to UV light.
- Support technicians available in Toronto, ON · Buffalo, NY · service center in Kentucky · or via the internet for diagnostics, calibration, and training.
- Competitive price.
- Familiar Windows operating system.
- Fully assembled and ready to go.
- Large stainless steel output table.
