Sign Manufacturing Process
We start by carefully selecting raw materials, including acrylic sheets, metal profiles, LED modules, and lighting parts to ensure stable quality. Then we use CNC cutting, laser engraving, bending, and welding machines to process the structure. After that, we do fine polishing and surface finishing to make sure every part is accurate and consistent.
For the lighting system, our engineers design LED layout and solder the wiring to ensure even lighting with no dark spots or shadows. We then assemble all parts together and apply waterproof, dustproof, and insulation treatment for long-term use.
Custom Letter Sign Manufacturing Process
We cut and bend metal into letter shells with CNC machines. We cut colored acrylic for front covers, then fit waterproof LED lights inside. We seal all gaps for water resistance and test every sign before packing.
In-House CNC & Laser Production System
At Hicen, we operate our own CNC engraving and laser cutting workshops with full in-house production across all processes.
All aluminum housings, back panels, and acrylic faces are manufactured internally without outsourcing or subcontracting, ensuring strict quality control and flexible modification capability.
Our fully self-managed production system guarantees stable quality, faster turnaround, and reliable project delivery for global signage clients.
Free design service from our professional design team, with the fastest turnaround of 1 hour for rendering.
We handle the entire cutting process in-house with no outsourcing, ensuring accurate dimensions, smooth edges, and no burrs.
We use professional bending equipment to precisely form aluminum returns, stainless steel, and other materials, ensuring smooth lines and a strong, stable structure.
We use professional painting processes to evenly coat aluminum and stainless steel parts, achieving various colors and finishes such as matte, gloss, and metallic effects.
We use 12/24V waterproof LED modules with evenly distributed lighting, standardized wiring, and sealed waterproof protection. Each product is fully light-tested and aged before shipment.
Our factory handles full in-house assembly, strictly controlling joint seams and sealing quality, with each finished product individually inspected before shipment.
Finished products undergo a 48-hour power-on aging test with full inspection of brightness and waterproof performance; any unqualified units are strictly rejected before shipment.
Finished products are securely packed with multi-layer pearl cotton, reinforced cartons or wooden crates, ensuring safe delivery and suitability for long-distance sea freight transportation.
Custom Light Box Manufacturing Process
We have developed a set of exclusive production workflows independently, which cannot be found in other factories. Our one-stop customized processing and special light calibration procedures greatly improve product stability and presentation effect.
LED light box signs free design by our in-house designers; drafts ready within 1 hour, and you may also provide your own design files.
All aluminum frames, LED components and backlit fabrics are sorted and prepped here before production.
Aluminum or acrylic profiles are precision cut to custom sizes per customer drawings before frame fabrication.
We use professional bending equipment to precisely form aluminum profiles into the light box frame, ensuring straight lines, tight corners, and a strong, stable structure.
LED parts are pre-assembled into modules before final assembly and undergo 100% aging testing, greatly shortening on-site installation time.
