Powder Metallurgy (P/M) is a long standing business that grew at a rapid rate from the 1980s. Much of its growth derived from powder-based parts replacing castings, forgings, and machined parts. The industry demonstrated that it could meet the needs of manufacturers but at a lower cost. More than 73% ofall P/M parts are sold to the automotive industry. P/M is useful in making parts that have irregular curves, or recesses that are hard to machine. It is suitable for high volume production with very little wastage of material. Secondary machining is virtually eliminated. Typical parts that can be made with this process include cams, ratchets, sprockets, sintered bronze and iron bearings (impregnated with oil) and carbide tool tips. P/M could potentially become an industry with saturated markets and grow mainly by acquisition or increasing market share. Though P/M technology has been widely used in automotive industry in many countries such as the United States, this technique is still new and not yet developed in Malaysia. Thus, this project is carried out to fabricate pinion gear for power window of car through P/M technique. The aim of this project is to optimize the P/M technologies so that it can be implemented in Malaysian automotive industry in future. The scope ofworks covers literature review, copy drawing ofexisting pinion gear, fabricate die and mould ofpinion gear, fabricate gears using P/M, conduct laboratory test and communicate the findings.
