200L-30000L Automatic Plastic Water Tank High Speed Blow Molding Machine

200L-30000L Automatic Plastic Water Tank High Speed Blow Molding Machine

Corner machine head of 200L-30000L Automatic Plastic Water Tank High Speed Blow Molding Machine is composed of a tubular head arranged in a right angle from the connecting pipe and the connecting pipe. The internal flow path of the head has a larger compression ratio, and the die part has a long set section, which is suitable for extruding polyethylene, polypropylene, polycarbonate, ABS and other plastics. It is especially suitable for the manufacture of plastic water tank.

Corner machine head of 200L-30000L Automatic Plastic Water Tank High Speed Blow Molding Machine is composed of a tubular head arranged in a right angle from the connecting pipe and the connecting pipe. The internal flow path of the head has a larger compression ratio, and the die part has a long set section, which is suitable for extruding polyethylene, polypropylene, polycarbonate, ABS and other plastics. It is especially suitable for the manufacture of plastic water tank.

Because the melt flow direction is turned from horizontal to vertical, the melt is prone to stagnation in circulation, and the length of the connection tube to the head die is different. The pressure balance inside the head is disturbed, which will cause the difference in the melt performance in the head, so that the melt can flow freely and smoothly when the melt is turned in the turn, and there is no stagnation point and weld joint. The spiral flow guiding device and the side feed head are mostly used.

This structure makes the melt runner of the blow molding machine streamlined and the helix angle of the helix is 45 to 60 degrees. This structure can not completely eliminate the weld line, but it is very suitable for the production of 20 - 30000L water tank. The usual measures are: first, the material in each passage should be converged at a high speed, and there is a uniform stay in the head of the machine; the two is to increase the pressure of the head of the machine and to promote the melting of the melt.
