1. The tunnel furnace has infrared IR, light curing and cooling system, widely used in screen printing, spray dyeing, drying, dehumidification and other processes such as electroplating and printed circuit industries, can also be used in food, textile, die young parts, surface coating and other industrial drying, baking. Can be arbitrary in the domestic and imported printing line, composed of complete production lines. 2. drying room temperature: room temperature -150 ℃ arbitrary; has hot, cold, UV-light, easy to operate, high efficiency. 2. set up hot air circulation system, temperature, air flow evenly, is not only prints dry quickly, and small shrinkage, ensuring the overlay accuracy of printed materials. 3. The variable frequency motor drive, variable speed, digital display, smooth transmission. The far-infrared heating lamps, controlled by a microcomputer. 5. access to material ends are equipped with emergency switch, to facilitate the operator to handle emergency situations, increasing security. 6. The high-pressure refrigerant, the workpiece after discharge, up to room temperature. 7. The machine according to different printed materials, different characteristics of ink, single lamp, multi-lamp combined operation, to ensure the quality of printed materials on the basis of, but also saves energy.
