With a dexterous look and sturdy construction, the machine is based on a combination of knitting principles with ergonomics and aesthetics. The whole machine adopts high-quality cast iron to avoid deformation of parts caused by aging effect under long-term natural or artificial conditions, with long service life and excellent production performance. The application of CNC machining centers and special surface heat treatments results in reliable long-term operation and durable machine parts. The transmission mechanism adopts German steel wire raceway bearings, which improves the operation accuracy, reduces noise and energy loss, and the machine is durable. The latest central adjustment device has a tolerance of less than 0.03 mm, which ensures the accuracy of the upper and lower levels, makes the weight adjustment spacing finer, and the coils are clearer and more consistent, thus giving the fabric a better feel.
