The rubber washers are rings made of rubber used in mechanical devices and are used to plug any sort of leak in the pipeline system, seal parts in contact with liquids. They are used to prevent vibrations from spreading from one part to another so reducing noise. These are mainly common with chemical and food industries as major consumers of rubber washers and gaskets, etc.

With the continuing and increase in the rate of construction works, the demand for rubber washers, many of which are imported, will increase. The project annual operating cost is US $ 129,466 producing 359,986 units annually translating into revenue estimated at US $ 179,993 per year. The net profit margin is estimated 28% with a payback period of 4 months. Thus is viable and can be put up in areas where access to prime properties is guaranteed.

Production Process

In manufacturing these products, rubber compounds are cut into moulds and pressed with the help of hand press, which are heated with steam, cut to required sizes and finally packed for the market. The profiled plant has a minimum plant capacity of 359,986 units of washers per year

Industrial houses are the major consumers of rubber washers. Therefore, the entrepreneur has to establish a network before entering the market. However, due to the booming premises’ construction in the country the market is promising.

Source of Equipment and Material

Equipment can be fabricated in Uganda at: Tonet Ltd, Kanyanya, Gayaza Rd, John Lugendo and Co Ltd Ndeeba Masaka Rd, email and Tree Shade Ltd, Mwanga II Rd- Kisenyi Kampala can provide this. Materials are both imported and locally purchased.

Government Intervention

Initial allowance of 75% granted in the first year of production on the cost base of plant and machinery for industries located elsewhere in the country. 25% start up granted on actual cost over the first four years in equal installments.

Risk certainty

The risk with this idea is in case of poor quality rubber rings, the business may lose its market. Therefore, the need for better management control.
