Solder Wire


1. Product Description:  Soldering is a process by which two metals are joined together by a third metal which is known as soldering wire.  The wire is an alloy of lead and tin.  Soldering is different from welding.  In welding the two same materials melt first and then join, while in soldering, the metals to be joined do not melt but the soldering wire melt and join the two metals on cooling.  Along with the soldering wire some flux is also used to help in adhesion.  Soldering wire is used in electrical, electronics, telephone, plumbing, radiators, scaling of tin cans, making of gas meters, etc.


2. Rationale and Market Potential:  Like practically all other industrial products, soldering iron is imported from abroad.  The Amhara Region receives its share of the import from Addis Ababa.  Annual consumption of this product by the whole country is 90000 tons and share of the Amhara Region is 25000 tons.  Production of soldering iron can be done either in small scale, medium scale or large scale operations.  If this is the case, establishment of a plant to produce soldering iron in the Region can be a viable venture.


      The plant can start by producing first to the Amhara market and gradually it can expand its operation to cover the market of neighboring regions.


3. Source of Raw Material:  As mentioned above soldering iron is alloy made from tin and lead and the two raw materials will be imported.


4. Production Process & Technology: The principal process is making the alloy by melting the two metals and the molten alloy is passed through a die (casting) to make it into a wire.  After cooling, the wire is rolled on a rotating wheel and then groups of wire are packed together.  Machinery and equipment include coke fire furnace, rolling machines, wire cutting, winding machines and other accessories.


5.  Estimated Investment: The plant requires a 300 m2 building which will cost Birr 300,000.  Plant and machinery will cost about Birr 300,000.  Total Investment birr 600,000.


     6. Benefits:  Saving foreign exchange resources to the country, self- sufficiency in a critically important industrial products, enhancing the development of the electronics, electrical, canning and telecommunication sectors.  Introduction of new technology and know-how to the Region.
