INDO F RKPOWER, PERFORMANCE...REDEFINED

Bremels was established in the year 1971 by the founder late Mr.B.R.Shetty. The vision and commitment of the founder, Board of Directors and top Executives, Bremels is recognized today in India as a force to reckon with when it comes to hot or cold retreading materials. The success in the field of tyre treads naturally promoted Bremels to enter into an equally challenging product group –Solid Cushioned (Resilient) Tyres. Here we depend on our strong technical support from one of India's top technocrat who not only has the product knowledge but also is fully conversant of product needs in USA, Europe and Far East.

We have a state of the art production unit, with in-house R & D facilities. Our factory is situated in the state of Karnataka, in the industrial suburb of the city of Bangalore at peenya and spread over an area of more than 90,000 sq. ft. During the last 38 years of our existence, our company has grown from strength to strength and has emerged as one of the major sources for quality tyre retreading materials.

Brand name 'BREMELS' has become synonymous with Quality and Performance.

Not all Tread Rubber is created equally. At BREMELS we pride ourselves on our hi- tech approach to the changing needs of the tyre retreading industry. We have earned over the years an enviable reputation for the consistent maintenance of quality of our products through research, technology upgrade and quality assurance – all areas we feel vital to meet the high standards of our valued customers. We are an ISO certified company.

On the international front we are exporting our products to many countries and our products have found acceptance in those markets flooding us with regular repeat orders. We have been exporting our product to more than 12 countries globally.

Today the company is steered by young dynamic team of well-trained professionals and having adequate educational background. Hence, Bremels is poised for a big leap ahead.

Load – Deflection curves

Ultimate performance of good solid tyre depends on load – deflection characteristics of its individual components. When put together they offer ultimate load – deflection properties to the finished tyre. Fig. 4 shows how Indofork tyre components behave under specific loads. For general comparison we have taken load- deflection characteristics of two leading European tyres, one is the toughest (competitive tough) and other is by far the best cushioned (competitive soft).

Combination of Indofork components ensures that the final tyre stays within these best European limits.

Stiffness without brittleness

When hardness of a compound goes up in conventional computing the stock tends to be brittle. In Solid tyre it would show layer separation and / or chunking or chipping.

Monsanto Co. in USA developed a new concept of using fiber web to reinforce rubber. Indofork core is based on such fiber web. Typical influence of web on rubber matrix is seen in fig.3. a properly compounded stock is further added with 10 to 25 parts of such a web material. Results are self explanatory.

Compound Testing

All Indofork compounds are tested on an advanced model of a Rheometer to control initial viscosity, Minimum viscosity, Scorch time, Optimum cure time and behavior after completion of cure fig. 2 shows typical curves of a tread compound and core. Every batch is tested to ensure that it is within specified limits.

Load Bearing Capacity

Solid Cushioned Tyres of Indofork make are engineered to provide high load bearing capacities and chemically protected from all deleterious effects of atmospheric oxygen, ozone flex, fatigue and shear. Typical section of Indofork Tyre is shown in fig.1. This is a beadless tyre that provides no slippage and better grip on wheels. It was possible to achieve this with latest techniques of using polyamide reinforcement.

Load carrying capacities of Indofork tyres are properly designed for front (load) and rear (steering) wheels for lift trucks and industrial vehicles.

Click (Easy Fit) Tyres

Development of easy Fit or Click tyres is extremely helpful in getting the right fitment with substantially higher

ease of fitment. In order to understand the designing of the Bead zone of the Click tyres one must study various

types of rims that are generally available for the mounting of conventional tyres.

2 Piece Rim: This is a very common design. Typical 5.00 – S – 12 Rim is shown in fig. 5. This assembly has only two

parts dividing the total rims in the center. While all conventional Indofork solid Cushioned tyres will fit this rim,

the Easy fit or Click tyres will not fit into this assembly.

3 piece Rim: This is shown in fig. 6. The total assembly consists of the locking Ring, the Side Ring and the Main

Rim. The Locking Ring locks the tyre and the side Ring into the rim slot. The tyre bead has to be shaped to suit this

and naturally conventional bead tyres will not fit this rim.

4 Piece Rim: Fig. 7 shows the assembly of this rim. It consists of Main Rim, Locking Ring and Side Ring. Again the

Bead zone has to be specially designed. When all the extra components viz. the Side Ring, Bead Seat Ring and

Locking Ring are removed what remains is the rim for Easy fit/ Click tyres
