3 - a.,,,,,,a Saudi Mechanica Industries Company SMI is a word-cass precision manufacturing company, offering a comprehensive service with emphasis on tota customer satisfaction. With a dedicated and experienced team of skied personne, we provide an efficient service to achieve the required specifications and quaity set by our customers. SMI utiizes Continuous Casters, fed by premet induction furnaces, in the production of its high quaity continuous cast bronze. The new faciity Continuous Casts up to " outside diameter in both soid and hoow bar. Centrifuga Castings are produced to a maximum outside diameter of 21" in maximum engths of 4". Extensive faciities and operationa versatiity enabes SMI to produce a variety of bronze aoys. SMI is ISO certified and, with fu in-house testing faciities, is abe to provide dimensiona, mechanica and chemica anaysis on request. Materia traceabiity is aso a standard procedure.

4 LG2 Bronze Sizes and Weights SMI manufactures both continuous and centrifugay cast bronzes, ranging in size from½ (.mm) to 21" (33mm) diameter. Aoys incude bearing bronzes, eaded bronzes, auminium bronzes, gear bronzes and manganese bronzes. Some bronzes and specia sections may require a minimum order quantity. The advantages of continuous and centrifuga casting of bronze incude : Reduced machining aowance Higher machining speeds Reduced too wear Exceent mechanica properties Homogeneous cose-grain structure Machining Aowance A sizes have the foowing aowance for finish machining. 3 " OD +.040" ID.00" 4" ;<;" OD +.00" ID.00" >" :S" OD +.04" ID." >" " OD +."

5 Imperia: Hoow Centrifuga Cast Continuous Casting Moten bronze is poured from a furnace into a crucibe which is cemented to the neck of a graphite die. The ower haf of the die is water cooed, meta sets in this section and is withdrawn through two sets of roers. A fying saw mounted beyond the roers cuts the bar to the required ength. Continuous cast rod has greaty improved physica properties compared with norma sandcast materia. Because of the bottom pouring conditions and rapid cooing that the meta receives in the cooing zone, incusions are competey eiminated, grain structure is tight and even giving exceent pressure tightness quaities. Tensie strength and wearing quaities are increased by up to 3% Centrifuga Casting Moten bronze is poured from the furnace into a piot ade which directs the stream of meta into a horizonta spinning die. The die determines the OD of the casting produced, and the amount of moten bronze fed to the die determines the wa thickness. When the die is fuy charged with the correct amount of meta it continues spinning for a predetermined period. On competion of the spinning process, the die end is removed, the casting withdrawn, proof machined and inspected. As with continuous casting this method produces an improved cose grained defect free materia.

6 C400 Auminium Bronze Continuous and Centrifugay Cast Aoy C400 has exceent strength, is hard and resistant to abrasion, wear, corrosion and impact. These physica properties remain good at eevated temperatures making C400 a suitabe aoy for high strength bearings, gears and worm whees. The tensie strength of C400 can be further enhanced with heat treatment if required.

10 Quaity Contro The principas of Quaity Management and Continuous Improvement are the foundation of our business. SM's documented quaity management system conforms to ISO001 /2000. The quaity of SMI Continuous Cast Bar starts with the introduction of the raw materia where experienced Foundry staff monitor incoming feed-stock to ensure ony the best materia for the required aoy is seected. From here the feed-stock is introduced to pre-met induction furnaces and sampes of each met are anaysed by spectrometer to ensure correct chemica composition is maintained throughout the production process. Upon confirmation of correct chemica anaysis moten bronze is transferred from the pre-met furnaces to the Continuous cast ine. Because of the bottom pouring conditions utiized by the horizonta casting process and the rapid cooing that the meta receives in the cooing zone, incusions are competey eiminated; grain structure is tight and even giving exceent pressure tightness, tensie strength and wearing quaities. The Continuous Cast Bar stock is then straightened, inspected for dimensiona compiance, cut to ength and racked ready for dispatch. With fu in-house testing faciities, SMI is abe to provide dimensiona, mechanica and chemica anaysis on request. Materia traceabiity is aso a standard procedure.
