Production Equipment &Testing Equipment
1.Production Equipment
According to “quality first,customers first” aim, we purchased advanced production and laboratory
equipment.
The vulcanizing machine linked production line for flameproof steel wire core conveyor belt is purchased
from Qingdao Beihai Machinery Co.ltd. To achieve mold by continous tension and meet the requirements of
vulcanization technology.
Adopt England Fenner’s technology to produce PVC/PVG flame-resistant whole core conveyor belt ,
standard the most advanced technology in domestic market. Cover rubber and impregnating paste core are
vulcanized directly under the high temperature, has high adhesive and long life. Adopt advanced national
knife coating process, 3 times skim-coating and 4 times plasticization to ensure thickness of the belt, good
soaks of rubber and good plasticization .
Plasticization box adopt electrothermal tube, compared to other factories which are in same line, ours
plasticization box is more wider and longer which can increase the valid heating area and have better
plasticizing effect.
Adopt constant tension rolling manners then can make the products neat and tidy.
