ARPHU brand rubber vulcanizing press machine adopts electric heating technology. It’s greatest advantage is that it is evenly heated by using rubber pressure plate, the machine works smoothly with uniform pressure. And it’s also equipped with portable automatic electronic control cabinet , which is easy to operate and has long operating life.
Rubber vulcanizing press (hereinafter referred to as belt vulcanizing machine), the main body is made of high strength aluminum alloy. Common power supply, temperature uniformity, with a fully automatic electronic control cabinet, pressure systems supply 1.5 ~ 2MPa , the joint strength can reach the original belts 90 % or more.
The rubber vulcanizing press machine is widely used in metallurgy, mining, cement, power plants, ports, building materials, chemical industry, able to carry out conveyor belt hot vulcanizing and repairing effectively.

Hot vulcanization principle
The hot vulcanization method is to peel the canvas layer and the rubber layer from a part of the conveyor belts joint into a symmetrical step according to a certain form and angle, apply the vulcanization cement to bond it, and then pass the vulcanization reaction under a certain pressure, temperature and time condition, the raw rubber is turned into vulcanized rubber, and the joint portion is glued together to obtain a higher adhesive strength. This welding method breaks the traditional cold vulcanization method, which not only has good joint quality, flat and smooth, but also can make the tensile strength of the belt joint reach 85 % to 90 % of the original conveyor belts.
Rubber vulcanizing press is a kind of vulcanizing device through stacking the two ends of the conveyor belt with the raw rubber material body in between, via heating device in which the raw material body is melted and the both ends of the conveyor belt are bonded together by a pressurization and heat retention process.
