The extrusion system adopts two-layer platform design for convenient operation and monitoring and can be attached with weightless extrusion control syste.
Advanced inner flow passage design makes the pressure loss of inlet and outlet water only 0.88Dar and thin wall design can control the roller surface temperature within +/-1.The uniform roller surface temperature and precise temperature makes it possible to improve the film performance and product rate dramatically,especially the adaptability for production of aluminium-plated base materials.
Infrared thickness gauge can take effective control to lateral uniformity and average thickness of the products by combining APC lateral control and linear speed vertical control.
Corona device can adjust the corona power acting on the surface of film automatically in light of the linear speed so as to achieve the same corona treatment value under different speed.After treatment,there is less temperature rise,no deformation and long time for maintaining of corona value and free of excessive reverse corona.
