3.1 the corrugated forming machine is arranged in a new horizontal structure. Compared with the vertical structure, the forming machine has higher rigidity, lower center of gravity, more stable operation and easier operation and maintenance;

3.2 the corrugated forming module adopts the innovative water direct cooling structure, which makes the cooling medium circulate inside the module at a higher flow rate and has high cooling efficiency, so as to ensure a higher output of the production line, up to 1800 kg / h (HDPE)

3.3 the innovative structural design of the molding machine makes the left and right frames open and close freely, which brings great convenience for flexible production. The left and right racks can be opened and closed through simple operation when replacing modules of different specifications or stopping at no-load, which can effectively avoid the cumbersome adjustment work caused by "holding" the die head by the corrugated forming module, so as to improve the convenience of equipment use and maintenance;

3.4 the unique design of the running track of the forming module can make the forming module run in both positive and negative directions;

3.5 the center height of the molding machine is fixed, and there is no need to adjust the frame or platform of the molding machine, so it is easier to use and operate;

3.6 advanced patented module manufacturing technology enables the cooling channel and vacuum channel in the precision cast corrugated module to be cast at one time, with high module strength and long service life, so as to ensure the high-quality and efficient production of pipes;

3.7 the automatic lubrication system is equipped with multiple lubrication points, which can set the lubrication time and frequency for automatic operation;

3.8 the position of the molding machine shall be adjusted electrically and equipped with perfect measuring and feedback devices; Accurately display the adjustment amount of each dimension.

3.9 the forming machine has the exit function in case of emergency;

3.10 the international famous brand PCC control system adopts modular control scheme, which has high compatibility, high control precision and high reliability.
