Bigwheel Retreading Indonesia. Retreading is the process where worn tyres are fitted with a new tread to give it a second life.The truth is, retreading is as old as the rubber tyre itself. Its history dated back to World War II when the natural resources were scarce and rationing in force. Civilians skinned the treads off vehicles damaged at the war and bonded them to their old tyres to give it a new life.
There are many methods being practiced to retread a tyre, but Cold Cure (Precure) and Hot Cure (Mould Cure) are the most common methods adopted by most retreaders worldwide.
Cold Cure (Precure)
As the name indicates, the tread rubber used here is molded and precured by the tread rubber manufacturer. The retreader selects the appropriate tread in strips or full circles of various designs, widths and thicknesses. In the precure retread process, a cushion gum bonding layer is placed between the tread and the casing. The proper tread width is applied to the prepared casing in a straight and even fashion. The tyre then moves on towards the curing chamber.
Curing now takes place within the chamber pressurized by heated air produced by electricity, steam or hot liquid such as oil. The prepared casing, with the new rubber in place, is put into the chamber where pressure and temperature, applied over the correct length of time cure the cushion gum layer and bond the tread to the tyre.
Hot Cure (Mould Cure)
This application of tread in the hot cure retread process is very similar to that of new tyre manufacture. Using one of several methods uncured tread rubber is applied to the crown area of the buffed casing (and in the case of bead-to-bead retreading, also to the sidewalls). The prepared casing, built up to the correct diameter with the uncured rubber material, is now ready to go into the mould for curing.
When the mold is closed and the tyre body inflated to the proper pressure, the swelling of the casing conforms the uncured material to the mould, forming the tread design. Heat is then applied for a specific period of time to accomplish curing.
Products Advantage
Our products are only as good as the materials used to make them.
Hence our insistence on using only premium tread-liners produced by renowned rubber compounder, for your earthmovers, dump trucks, fork-lift, bus, haulage and light truck. Excellent raw materials are complemented by the latest in German technology and finally subjected to stringent quality control tests in the making of a Bigwheel´s product.
