The SF series of stranding machines is available in multiple models, providing customers with more options in stranded wire structures and working efficiency. The steel wire stranding lines in this series is equipped with efficient sound insulating devices which effectively reduces noise. Additionally, this stranding machine uses a draught fan and exhaust fan in its main chamber, hence reducing the temperature so the cable manufacturing machinery is more durable.
