Buyers usually start with working width and price. The heat source is what they live with for the next ten years.
Xinghua Machinery has built textile coating machines in Wuxi Qianzhou since the predecessor factory was established in 1993. The limited company was registered in 2003, and still builds only equipment: no trading, no turnkey contracting. ISO 9001 certificate 54326Q00104R253 covers “manufacture of textile finishing equipment and carpet finishing equipment”. Four workshops sit on one site — machining, structural, sheet metal, assembly — so the oven, the frame and the coating head are all made under the same roof as the machine that carries them.
Thermal oil
Thermal oil is a closed loop: the oil heater sits outside the oven, oil circulates at a set temperature, and the chamber sees a steady figure. On our lines the oil loop is held at 250 °C. For heavy coated fabric such as tarpaulin, and for carpet backing where the coating has to cure through a thick layer, steady is worth more than fast. The cost is a separate oil heater, a pump set and a loop that has to be maintained.
Gas
Gas heats quickly and the oven reaches working temperature sooner after a cold start. It also means a burner train, gas supply stability and local safety requirements become part of your plant. Where the local gas supply is steady and the fabric mix changes often, gas is the practical answer.
Steam
Steam is usually chosen where a boiler already exists. Its temperature follows pressure, so the ceiling is lower than with thermal oil, and the oven responds more slowly. For lighter coatings and for plants that already run steam for other processes, it keeps the utility side simple.
What decides the result is not the fuel, it is the zoning
A single temperature number across a 4.2 m oven is not a setpoint, it is an average. The oven temperature controller (patent CN206131698U) zones the chamber, so the entry zone, the curing zone and the exit zone can hold different figures. Two related patents are on the same logic: the carpet oven (CN206131638U) and the combined coating head (CN205995709U), which lets you change coating weight by changing the head instead of dismantling the machine.
Working width 1.8–4.2 m, variable speed drive, heat source thermal oil, gas or steam. 29 published models: 8 coating machines, 3 stenters, 14 carpet finishing machines, 1 electrostatic flocking machine, 3 others. More than 15 countries and regions, including Korea, Japan, Turkey, Egypt, India, Pakistan, Thailand, Uzbekistan, Argentina, the Netherlands, the UAE and Indonesia.
119 patents is the company total, and it includes carpet and flocking machinery. For the coating machine itself, the four patents that matter are the ones with “coating machine” or “coating” in the title: combination coating head CN205995709U, combined infeed frame CN205995743U, temperature-controlled infeed frame CN205995744U, electro-hydraulic servo control for carpet coating CN206111703U.
Lead time is about 3 months, 4 for special models; 30% deposit, balance before shipment; sea or land freight; one-year warranty, on-site installation and commissioning, engineers available overseas, lifetime service. The trial run happens after installation and commissioning at the customer’s plant, with the customer’s own fabric.
