Of course, Kingsun Machinery provides full after-sales support, including installation assistance. For large production lines like rotogravure printing or hologram machines, we can send technicians to your site for setup. For other machines, detailed installation guides, videos, and remote support are provided. Our dedicated technical team ensures fast responses and long-term service, so you can run your production smoothly and worry-free.

Kingsun rotogravure printing machines have different width: from 600mm to 1800mm width, from 1 color to 12 colors, speed from 150m/min to 450m/min. Our rotogravure printing machine with shat drive (mechanic shaft) or servo drive (shaftless) type, which fit for paper, film or foil etc. machine with different configuration, adopts world latest technology parts, with reliable performance for gravure printing.

Printing Plate Cylinder: The plate cylinder is typically designed and manufactured by specialized factories. Producing a plate cylinder for your specific design involves over 15 precise processes, resulting in high accuracy and wear resistance. We have established long-term partnerships with reputable plate cylinder manufacturers. If you need support, we are happy to help you. Every year we export thousands of printing plate cylinders)

Doctor Blade System: Equipped with electric adjustment and lateral oscillation mechanisms, it ensures uniform pressure distribution, effectively reducing streaking (doctor blade lines).

Drying System: Utilizes an efficient hot air circulation drying system, which is energy-saving and provides even drying, compatible with various ink types.

Tension Control: A fully automatic tension control system maintains material flatness and ensures consistent web tension throughout the printing process.

Registration System: Features a fully automatic color registration system, employing the latest domestic or imported registration technology (e.g., Kesai), guarantee precise printing registration during production (accuracy up to ±0.1mm).

The price of a rotogravure printing machine is influenced by multiple factors including printing width, number of color units, printing speed, compatible substrate materials, and additional configurations (such as automated registration systems, inspection systems, and special functions), as well as the choice of component brands. Typically, prices range from USD 50,000 to 1,000,000. We can recommend the most cost-effective solution tailored to your specific budget and flexible packaging production requirements.

The delivery lead time for standard models is 1–3 months, depending on the specific model. Customized gravure printing machines may require a longer production period. Installation and commissioning are handled by our engineer team. We will send technicians to your factory for installation, and operator training, which typically takes 2–4 weeks. Sea freight duration varies depending on the destination port. We recommend preparing visa applications for our technicians upon departure shipment of the machine, so they can travel to your factory promptly upon the machine's arrival.

A Dry Laminator is a machine that bonds two layers of substrate using solvent-based or water-based adhesives. The process involves applying the adhesive, drying it in an oven to evaporate the solvents/water, and then pressing the layers together. Its advantages include wide material compatibility (especially for aluminum foil and metallized films), high peel strength, and mature and reliable technology. Disadvantages are higher energy consumption, solvent emissions (requiring separate treatment systems), and a relatively larger space needed.

A Solventless Laminator bonds two layers using 100% solid-content adhesives. The adhesive is applied, and the materials are pressed together by big cylinders at room temperature or slightly elevated temperatures, where they chemically cure. Key advantages are environmental friendliness (zero VOC emissions), energy efficiency, high operating speeds, lower operational costs, and a more compact machine size. The main challenge is its higher sensitivity to material surface tension, workshop environmental conditions, and precise process control.

Peel strength depends on the perfect synergy between the materials, adhesive, and process parameters. Our laminators ensure optimal bonding through:

 Precise Coating System: Guarantees uniform adhesive application. For Dry Laminators, it precisely controls the adhesive coat weight (e.g., 2.5-4.0 GSM). For Solventless Laminators, it accurately controls the adhesive mixing ratio.

Uniform Drying/Laminating Pressure: Dry Laminators feature independently controlled temperature zones in the drying oven. Solventless Laminators have evenly stabilized nip roller pressure.
Professional Process Support: We provide initial parameter sets for various material combinations as a starting point for your production. Additionally, comprehensive operator training is included with the purchase of our equipment.

Our machine is compatible with common laminated flexible materials such as BOPP/CPP, PET/PE, PA/PE, and Alu Foil/PE etc. The prerequisite is that the materials must be pre-laminated, supplied on rolls with good flatness and uniform tension. For materials with extremely high or low coefficients of friction, or with excessively thick or thin sealing layers, it may be necessary to adjust the machine's process parameters, such as setting appropriate temperature and pressure, so can ensure the final pouch quality meets quality standards.

Our 3-Side Seal Pouch Making Machine ensures seal integrity and quality through several key design features:

Intelligent Temperature Control: Utilizes a PID closed-loop control system with independent, precise temperature zones (±1°C), ensuring stable sealing knife temperature.

Adjustable Pressure & Dwell Time: Features pneumatic or servo-driven sealing pressure for precise adjustment, combined with servo-driven control of sealing dwell time, to adapt to different materials.

Dual Sealing & Cooling Process: The standard configuration includes pre-sealing followed by main sealing, coupled with a cooling station. This prevents heat distortion and ensures the seals are strong and flat.
