Product description


1. Material quality: The coat is 304 stainless steel, the water jacket is the high compression casting aluminum tube, the red copper coil.

2. Online testing of technical parameters to ensure the consistency of data product parameters

3. Mechanical size 100% meet the requirements, to ensure that there is no greater error in the use process

4. Automatic assembly line

Automatic assembly line, improve production efficiency, low cost without human operation, one line down intelligent mechanical automatic assembly

5.Electromagnetic furnace optimization design, lift torque, reduce temperature rise, so that the motor running smoothly

Stepping motor is a mechanical structure,which does not need be changed by electric brush or Hall sensor,thus reducing the probability and increasing the motor life.Stepping motor life usually determined by the life of the bearing.

6.Automatic machine operation, stable automatic work, high processing efficiency.
