Our flagship gel coating sheet production lines are purpose-built for manufacturing high-performance FRP panels used in truck bodies, cargo containers, and commercial vehicle bodywork. Explore our core machine models below.
The global commercial vehicle industry is undergoing a material revolution. FRP gel coating sheets have become the preferred solution for truck body panels — combining lightweight performance, corrosion resistance, and superior aesthetics.
Global demand for FRP truck body panels is growing at a CAGR of over 7% through 2030. Logistics fleets, refrigerated transport, and long-haul trucking operators are rapidly replacing traditional steel and aluminum panels with FRP gel coat sheets due to their 40–60% weight reduction and zero-rust performance.
Modern truck body manufacturers are transitioning from manual lay-up processes to fully automated continuous FRP sheet production lines. Gel coating sheet making machines enable consistent panel quality, faster throughput, and reduced labor costs — making high-volume production economically viable for manufacturers worldwide.
Stricter emission standards in the EU, North America, and Asia are pushing fleet operators to reduce vehicle weight. FRP gel coat panels — produced by advanced sheet making machines — directly contribute to fuel efficiency improvements of 8–15%, helping manufacturers meet CO₂ compliance targets while reducing operational costs.
DNUO's FRP gel coating sheet making machines integrate cutting-edge automation, precision resin distribution, and intelligent control systems — delivering superior panel quality for truck body applications.
Automated gel coat spraying systems deliver uniform coating thickness (0.3–0.8mm) across the full panel width, ensuring a mirror-smooth, high-gloss surface finish ideal for truck body aesthetics.
Patented continuous belt-press forming ensures consistent panel density and thickness across production runs up to 2,500mm wide — meeting the dimensional demands of large truck body panels.
Full PLC automation with touchscreen HMI allows precise control of resin ratio, curing temperature, belt speed, and gel coat viscosity — minimizing defects and maximizing production efficiency.
Capable of integrating fiberglass mat, woven roving, and surface veil in a single pass — producing structurally optimized panels that meet truck body impact resistance and flexural strength requirements.
DNUO's continuous production line transforms raw fiberglass and resin into finished, road-ready truck body panels through a streamlined, automated process.
High-quality polyester or vinyl ester gel coat is uniformly applied onto the carrier film to form the outer surface layer.
Chopped strand mat and woven roving are laid onto the gel coat layer via automated dispensers for structural reinforcement.
Calibrated resin distribution rollers ensure complete wet-out of fiberglass reinforcement with minimal void content.
Precision-controlled curing ovens with multi-zone temperature management ensure optimal resin crosslinking and panel rigidity.
Automated flying saw cuts panels to exact customer specifications, ready for direct installation on truck body frames.
FRP gel coating sheet making machines serve a wide spectrum of truck body and commercial vehicle applications — each demanding specific panel performance characteristics that DNUO machines are engineered to deliver.
FRP gel coat panels produced by DNUO machines are the material of choice for refrigerated truck bodies. Their inherently low thermal conductivity, combined with a seamless gel coat surface that resists moisture ingress, makes them ideal for insulated panel sandwich construction used in cold chain logistics. The smooth, cleanable surface also meets food-grade hygiene standards required by regulatory bodies in Europe, North America, and Asia.
High-gloss FRP gel coat side panels for dry van trailers and box trucks offer superior impact resistance compared to painted aluminum or steel. The gel coat surface integrates UV stabilizers during the machine production process, providing long-term color retention without repainting — significantly reducing fleet maintenance costs over a 10–15 year vehicle lifespan.
Chemical-resistant FRP gel coat panels produced with vinyl ester resin formulations provide excellent resistance to acids, alkalis, and solvents. DNUO's gel coat sheet making machines can process specialized corrosion-resistant resin systems, enabling manufacturers to produce panels certified for chemical tanker body linings and hazardous material transport applications.
As the EV commercial vehicle market expands globally, reducing body panel weight is critical to maximizing battery range. FRP gel coat panels from DNUO production lines weigh 40–60% less than equivalent steel panels, directly extending electric truck range by 8–12% — a compelling value proposition for EV fleet operators and OEM manufacturers transitioning to electric powertrains.
Fire trucks, ambulances, and military logistics vehicles demand body panels that combine lightweight performance with structural integrity under extreme conditions. DNUO's gel coat sheet machines produce panels with flame-retardant resin systems, meeting international fire safety standards while providing the dimensional precision required for emergency vehicle body fabrication.
The explosive growth of e-commerce has created massive demand for urban delivery vehicles. FRP gel coat panels enable manufacturers to produce lightweight, aerodynamic body panels for last-mile delivery vans and micro-trucks. The ability to produce complex embossed and textured surface finishes on DNUO machines adds brand differentiation value for fleet operators and logistics companies.
The FRP gel coating sheet making machine industry is evolving rapidly, driven by sustainability demands, digitalization, and the global shift toward lightweight transportation solutions.
Next-generation FRP gel coat sheet machines are being engineered to process bio-based and recycled resin systems, reducing the carbon footprint of truck body panels by up to 35%. DNUO is actively developing resin delivery systems compatible with bio-polyester and epoxy acrylate formulations to meet evolving sustainability mandates.
Machine vision systems and AI-powered defect detection are being integrated into FRP production lines. Real-time surface inspection cameras linked to PLC control systems can automatically adjust gel coat application parameters, reducing panel rejection rates to below 0.5% — a critical advancement for high-volume truck body panel manufacturers.
DNUO's latest machine generation supports IoT connectivity, enabling remote monitoring of production parameters, predictive maintenance alerts, and cloud-based production data analytics. This digital transformation allows truck body manufacturers to optimize OEE (Overall Equipment Effectiveness) and reduce unplanned downtime across multi-line production facilities.
Emerging UV and LED curing systems are replacing traditional thermal ovens in FRP gel coat production lines, reducing energy consumption by 40–55% and cutting curing time from minutes to seconds. DNUO is pioneering the integration of hybrid UV-thermal curing systems optimized for truck body panel production speeds exceeding 8 meters per minute.
The trend toward modular, scalable production line design allows truck body manufacturers to start with core gel coat sheet production capability and progressively add embossing, in-line cutting, and automated stacking modules as production volumes grow — reducing initial capital investment while preserving future expansion flexibility.
Rapid infrastructure development in Southeast Asia, Africa, and South America is driving new demand for commercial vehicle manufacturing capacity. DNUO's export-ready machine configurations — with multilingual HMI, local voltage compliance, and comprehensive remote commissioning support — are positioning FRP gel coat sheet production technology for accelerated global adoption.
