Used post processing machine in China

Overview

Laminating and coating equipment applies protective films, adhesives, or liquid coatings to substrates like paper, cardboard, plastics, textiles and metal foils. Common in packaging, printing, label and industrial finishing, machines range from roll-to-roll and sheet-fed laminators to extrusion, hot-melt and cold adhesive coaters. Buyers evaluate web width, line speed, temperature and tension control, drying/curing systems and rewinders to match throughput and material compatibility.

FAQ

What should I inspect when buying a used laminating or coating machine?

Check rollers and sleeves for wear, heater and control panels, pumps and metering systems, web tension systems, drive motors, and condition of entry/exit guides. Ask for recent service records and a live run test with similar materials.

How do I choose the right machine size and speed for production?

Match web width and maximum line speed to your highest-volume job, and ensure the machine’s heating/drying capacity and unwind/rewind sizes support your rolls. Leave some margin for future growth.

What electrical and utility requirements should I confirm?

Confirm voltage, phase and amperage, compressed air pressure/flow, steam or hot oil systems if used, and any cooling or ventilation needs. Verify site capacity before delivery.

How should laminators/coaters be shipped to avoid damage?

Use heavy-duty crating, secure movable parts, drain fluids, lock or remove delicate rollers, and work with carriers experienced in industrial web equipment. Consider partial disassembly and professional rigging.

Are spare parts and consumables easy to source for older machines?

Parts availability varies by make and age. Common items like rollers, bearings, adhesives, and heaters are usually obtainable, but custom doctor blades or obsolete controls may require aftermarket or refurbished solutions.

What routine maintenance keeps a laminator or coater reliable?

Regularly clean rollers and heaters, inspect seals and bearings, calibrate tension and metering systems, replace worn sleeves and belts, check electrical connections, and follow manufacturer lubrication and inspection intervals.
