We combine cutting-edge technology with expert craftsmanship to produce durable, specification-compliant signage — crafted in a state-of-the-art manufacturing facility. Complete in-house fabrication from raw materials to finished sign. No fabrication is subcontracted, and every sign is tested for electrical performance and LED illumination uniformity before it ships.
2× CNC Channel Letter Bending Machines
Channel letters at Wholesale Sign Pro are formed on CNC channel letter bending machines — computer-controlled systems that bend aluminum, stainless steel, brass, copper, and galvanized steel coil stock into precise letter returns for any font, letter height, and return depth. The bending systems produce flanging returns, front-lit, trim-less, reverse halo-lit (without welding), front- and back-lit, and side-lit plastic return channel letters, including the smallest letter sizes (3" height) with no maximum height limit. Aluminum coil from 0.040" to 0.063" and return heights from ½" to 8" are processed on the system.
CNC Trim Machine
A dedicated CNC trim machine processes plastic trim or converts flat aluminum into aluminum trim — an option for projects that require metal trim rather than a standard plastic trim cap.
Dual-Gantry CO₂ and Fiber Laser Cutter
Acrylic faces, aluminum sign panels, stainless steel components, and metal cabinet parts are cut on a dual-gantry laser system with two independent cutting heads operating simultaneously on a single large-format table. The 500W CO₂ gantry cuts non-metals — acrylic up to 1" thick — while the 3000W fiber gantry cuts aluminum, stainless steel, brass, and carbon steel. Running both gantries simultaneously allows acrylic and metal components for the same order to be processed in parallel, reducing production time on multi-material sign orders.
Fiber Laser Welders
Aluminum and stainless-steel channel letters that require welded construction — complex contour shapes and custom logo components — are welded using fiber laser welding systems, with no post-weld grinding required. A handheld continuous fiber laser welder handles larger-format welding tasks, structural sign components, and cabinet fabrication. Fiber laser welding produces significantly cleaner and more consistent results than MIG or TIG welding on sign-gauge aluminum and thin stainless steel.
MIG Welders
Structural sign components — pylon sign bases, monument sign frames, cabinet sub-structures, and custom support brackets — are fabricated using heavy-duty MIG welders. MIG welding covers the full-penetration structural welds required for load-bearing sign infrastructure that fiber laser welders are not designed for. The facility operates multiple MIG welding stations capable of welding mild steel and aluminum (with spool gun).
CNC Routers — 6′×12′ and 4′×8′
Dimensional sign components, PVC trim, polycarbonate backs, and routing-specific material profiles are processed on heavy-duty CNC routers built for production volume on acrylic, aluminum, PVC, and polycarbonate — complementing the laser cutter and supporting solid laser-cut letter production.
Industrial 3D Printer
Complex letter returns, script-font channel letters, tight-radius shapes, logo components, and custom sign elements that cannot be formed by conventional aluminum bending are produced on industrial 3D printing systems specifically designed for sign manufacturing. The printer bed is 600 × 600 × 120 mm (23.6" × 23.6" × 4.7") — large enough to produce multiple letter returns per print run — and operates at an extrusion speed of 31 mm³/s, the fastest in its class for sign production.
Professional Spray Booth
Assembled sign cabinets, channel letter raceways, monument sign panels, and large structural components are painted in a dedicated, ventilated professional spray booth sized for commercial sign production. Controlled airflow, overspray containment, and compliant exhaust filtration produce a uniform, contamination-free paint finish on powder-coated aluminum, primed steel, and raw fabrications — conditions that cannot be replicated in an open shop environment. Custom color matching, multi-coat finishes, and sign programs with specific RAL, PMS, or brand-standard color requirements are all handled within the spray booth finishing process.
Bubble Roll Packaging Machine
Finished channel letters and sign components are wrapped in protective bubble cushioning with an automated bubble-roll machine before crating and shipment. The machine produces consistent, uniform bubble wrap coverage on every letter — protecting acrylic faces, aluminum returns, and LED components from transit damage without relying on manual wrapping consistency.
LED Light Meters
The light output and face brightness of completed channel letters are measured with professional LED light meters before each order is packaged and shipped. Light meter testing verifies that illumination meets the specified brightness and is consistent across every letter in the set — identifying underpowered LED modules, driver configuration errors, or face material variations before they reach the customer. Brightness readings are documented per order for quality-sensitive programs and national brand rollouts where uniform illumination across multiple locations is a requirement.
