1.Manual setting and automatic repetition guaranted the product homogeneity and save on time and work intensity. 2.There are two speeds set for the basic shaft, ensuring its maximum function utilization in thicker and thinner material bending. plete dies of block, so basically meeting the requirements of iron craftwork processing. 4.Having a broad processing range, it usually can twist 200mm-800mm long pretzel part. If longer than 800mm, we can twist by segment. With high efficiency it can twist 400 pieces of 12mmX12mm square steel per hour.
