Explore our primary machinery portfolio engineered for commercial printing, packaging converters, and folding carton manufacturers worldwide.
In modern post-press operations, achieving high surface gloss, superior rub resistance, and eco-friendly recyclability has become a core operational imperative. As a premier China High Speed Varnishing and Calendering Machine Supplier & Factory, Guangdong Shanhe Industrial Co., Ltd. delivers sophisticated finishing systems designed to replace legacy, energy-intensive film lamination with high-efficiency water-based and UV varnishing technology.
Our HSY and HSG series full-automatic high-speed varnishing and calendering machines apply uniform liquid varnish onto printed paper substrates. Through thermal calendering under mirror-polished chromed rollers, substrates achieve a mirror-like finish with gloss ratings exceeding 90+ GU (Gloss Units).
Global regulations (such as the EU single-use plastic directive) are shifting converters away from plastic film lamination (BOPP/PET). Water-based (aqueous) and solvent-free UV varnishes provide 100% recyclable, biodegradable surface barriers without compromising luxury visual appeal.
Engineered for high-volume folding carton lines, our equipment delivers precise registration at speeds up to 10,000 sheets per hour. Inline integration reduces process steps, labor footprint, and turnaround time for folding carton plants.
The SHANHE HSY-120 and HSG-120 series represent thirty years of R&D refinement. Built on heavy-duty cast-iron machine frames, our equipment ensures vibration-free operation under continuous 24/7 high-speed production conditions.
Utilizing high-precision ground ceramic anilox rollers paired with reverse-angle doctor blade assemblies, our machinery achieves film thickness accuracy within ±0.002 mm across full-width sheets (up to 1200 mm width). This prevents orange-peel effects, pinholes, and streaking.
The core calendering cylinder is forged from high-density alloy steel, surface-ground, and hard-chrome plated with a surface roughness of Ra 0.01 μm. Heated via an internal oil-recirculation heat exchanger, it delivers uniform temperature distribution up to 150°C, pressing micro-grooves flat to generate unmatched specular reflection.
Featuring intelligent multi-zone IR heating tunnels for water-based varnishes and high-intensity UV curing lamps for UV coatings. Automatic sensor-driven energy adjustment throttles lamp power relative to line speed, reducing thermal stress on sensitive paper stocks.

As international brand owners mandate sustainable packaging solutions, converters in Europe, North America, Southeast Asia, and the Middle East are re-tooling post-press departments. Plastic film lamination faces strict landfill penalties and recycling bottlenecks. Inline water-based varnishing followed by high-pressure thermal calendering provides the exact visual profile of film lamination while preserving 100% paper recyclability.
Focuses heavily on VOC reduction and food-grade barrier coatings. SHANHE machinery supports low-migration aqueous coatings and LED-UV curing systems that meet strict EU regulations.
High-speed throughput and rapid job changeovers. Our non-stop feeder and delivery stackers eliminate downtime during continuous high-volume folding carton production.
Rapid expansion in consumer goods manufacturing requires cost-efficient, durable machinery with low maintenance requirements and quick return on investment (ROI).
Different end-use packaging sectors require specialized surface treatments. Shanhe Machine engineers tailors configurations to meet rigorous industry demands.
Requires ultra-high gloss without yellowing or micro-scratching. Calendering applies high temperature and hydraulic pressure to achieve a mirror sheen on rigid setup boxes, perfume cartons, and lipstick packaging.
Demands anti-rub resistance, smudge-proof surfaces, and compatibility with downstream braille embossing and high-speed folder-gluers. Our spot UV and aqueous coaters prevent coating migration on medicine boxes.
Focuses on moisture-barrier properties, grease resistance, and non-toxic water-based formulations for frozen food boxes, confectionery cartons, and wine display cases.
Combines heavy-weight cardboard substrates (up to 600 g/m²) with heavy scuff protection, ensuring retail boxes maintain structural aesthetic during transoceanic shipping.
Buying directly from a China high-speed varnishing and calendering machine factory requires complete confidence in quality control, electrical compliance, and global after-sales infrastructure.
Every machine manufactured in our 34,175 m² Shantou plant complies with strict European Union CE safety machinery directives, including emergency safety light curtains, interlocked guards, and Siemens CE-compliant electrical enclosures.
Our senior mechanical and electrical engineers deploy directly to customer sites globally. We provide complete commissioning, operator calibration training, and preventive maintenance instruction in local languages.
Equipped with IoT remote diagnostic modules, our service center can analyze PLC logs live over secure cloud channels. Wear parts and replacement metering rollers ship within 24–48 hours via global express networks.
As Industry 4.0 digitizes packaging production, SHANHE MACHINE is pioneering smart post-press ecosystems. Our R&D center focuses on four core technological evolutions:
Real-time ultrasonic sensors continuously measure varnish viscosity and temperature inside the reservoir, automatically injecting solvents or water to guarantee constant coating weight across 100,000-sheet runs.
Transitioning traditional mercury UV units to cold-cure LED-UV arrays reduces curing energy consumption by up to 50% while completely eliminating ozone emissions and heat-induced paper curling.
Standard OPC-UA protocols allow seamless connection to plant-wide Manufacturing Execution Systems (MES), providing production tracking, predictive component wear alerts, and automated job setup recall.
Comprehensive answers to key technical, operational, and purchasing inquiries for factory managers and procurement directors.
