We are a professional entity who is manufacturing and exporting the whole production line of pre-stressed concrete pole.
I Introduction
Our factorty is leading manufacture of Pre-stressed Concrete Pole Manufacturing Plant in China.We are a professional company covering the comprehensive and systematic business scope including technological design, fabrication, field erection and commissioning, personnel training and technical service in the field of Pre-stressed concrete pole production line.
Pole steel mould is used for electronic concrete pole making. Its mainly processing technology is longitudinal tensioning the steel wire, then squeezing out the excess water in the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength after steaming in the pool.
Pole spinning machine is operated by remote-controlled continuously variable motor. It runs smoothly and has a variable-speed range. So the final products are good at quality and appearance. The base of the machine is welded in box-type structure, sturdiness and durability. The bearings are sealed and reliable, long life. Random electric control equipment is complete and easy to use.
II Features
1) Welding technique, which enhance the smooth finish of the mould wall, and eliminate uneven traces of rivet holes. So the concrete poles appearance will be improved significantly.
2) The cylinder is changed to U-longitudinal stiffener, it can greatly increase the stiffness and flexural strength of the steel mould,
3) Install the slot with plastic sealing strip, in order to prevent leakage to ensure quality.
4) Saving a great deal of steel, about 30~70% (employing cold drawn steel wire can save 30%~60%; employing high stress steel wire can save 40%~69%);
5) Crack resistance increased 3~5 times;
6) Rigidity increased 1~3 times;
7) Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%);
8) Good durability, can delay the existence and expansion of cracks;
9) Protect the environment on which human beings depend on for existence, and reduce the deforestation.

IV Work principle
1) The steel mould works with pole spinning machine. The steel mould should be placed onto the spinning machine smoothly.
2) Adding the slurry into the mould, it is driven quickly and rotated in the same speed of the machine. Each component is separated and released under the centrifugal force. Usually the higher the slurry rotate, the better the slurry separate.
3) Centrifugal sedimentation is the use of different density of each component in the slurry, which is rotated under the centrifugal force. To realize the liquid - solid (or liquid - liquid) separation.
4) The speed of separation is slow when the viscosity of slurry is high.
5) It is good for centrifugal sedimentation when the slurry density is different in each component.
