      There are differnt size for vulcanizing tank.It is very important to tire retreading.For example,4tyres, 5tyres, 6tyres,8tyres,10 tyres,12tyres,14 tyres,16 tyres,18 tyres,20 tyres,22 tyres,24 tyres and 26 tyres for all kinds of tire.

 

Benefits of tyre retreading:

      The benefits of retreading are that it is both environmentally friendly and cost-efficient! When the tread has worn off, only about 20% of the tyre is used up. The carcass, which represents about 80% of the tyre's value, can be re-rubberized for a "new tyre life".

      To produce a truck or bus tyre requires about 60-80 kg of rubber mixture. Retreading the tyre takes only about 15 kg of rubber. A considerable amount of raw materials can therefore be saved. In the EU, this equates to more than 300,000 tones per year!

      To produce a car tyre requires about 28 litres of crude oil. To retread a car tyre, on the other hand, only 5.5 litres of oil are needed.

About the making operation of tire retreading machine:

 

First, tyre body testing

The Prevulcanized retreading method is different from the traditional heat retreading techniques; it has more strict requirements on the tyre body. At first, the ring can not have broken wire, tyre appearance must be intact; the second , the tyre side face can not have too much broken scar, even broken thread. If rubber surface is aging and burned heavily, it can not be renew, the third, small pinhole surface can be renovated, but local wearing depth can not exceed three layers. Radial tyre steel wire should not broken, drawn wire or rust marks are not allowed.

 

Second: The tyre body drying process

Due to the long circulating time over market, there is much dust, dirt and other debris on the old tyre body surface, in order to improve the tyre appearance and enhance inspection result; we have to clean them carefully before the drying process. The aim of drying is to wipe off the water inside innerliner, so as to avoiding the tread surface and inside layers delaminating.

 

Third: The tyre body polishing process

A qualified tyre body, after the certain period of drying process, it should meet the first turn polishing process by "pneumatic tyre profile grinding machines", so as to clear the waste tyre body surface. According to strict requests, the polishing action must follow the tyre body's radian and depth direction. After this step, different kinds of tyre matrix need further manual repair on the hole and scar parts, to get a rough and clear surface.

 

Fourth: The tyre molding process

Put the polished tyre on the shelf spreading the pre-mixed glue on the surface of tyre. In the meantime, put the prepared tyre outer layer on clear board also spreading glue on it, waiting for two layers become dryer, then gluing them together by tread pressed machine to expel air inside and intensify the tyre body and tread bonding strength.

 

Fifth: The installation of tyre accessories

Put the glued tyre in the package envelope disassembly machine to finish the tyre outer packing, and then use the wheel changer, special wheel rim and chuck to intensify the outer packing coat, finally put the finished tyre into vulcanizing tank to get vulcanization process.

 

Sixth: Tyre vulcanization process

Because this process is the pre-vulcanization(cold turn) retreading tyre, so it has special requests towards the vulcanizing temperature and vulcanizing time. Through tyre inflating, tank inflating, and outer packet inner groove inflatable technique, and under certain scientic and reasonable time and temperature "physical" vulcanizing, the tyre surface and body part can glue together tightly.

 

Seventh: Product testing

Make serious testing towards the vulcanized tyre, so as to avoiding undetected bad products into the market, 

resulting in unnecessary trouble and losses.
