Shah Alam Manufacturing Complex
Our rising story begins from here! On the 9th of July, 1985, our first manufacturing plant kicked off in Malaysia and the same year Proton rolled out as its first car, the Proton SAGA which is considered to be Malaysia's national car. It was an important moment that laid the foundation of Malaysia’s automotive industry. Then, the journey of success began and since then we have expanded our branches to include a host of new facilities. Proton SAGA has attained many milestones and became the catalyst that powered PROTON to sales of more than 4 million units of PROTON vehicles. High-class engines and assembly building inside the complex manufacture and assemble cylinder blocks, camshafts, and crankshafts for the CamPro engines.
Along with the chief plant, there comes a manufacturing complex that hosts a Multi-Vehicle Factory also known as the “Shah Alam Manufacturing Complex”.
Tanjung Malim Manufacturing Complex
Our plant of Tanjung Malim was officially kicked off in 2004 and started its operations that same year. The aim of building this masterpiece is to strengthen our production capacity to make sure that the demands of all the vehicles of PROTON are met effectively. It holds a capability of 150,000 units annually. Moreover, approximately 60% of its processes are geared towards increasing its efficiency, automation, and safety. This helps in providing a safe working environment where all the machines and men can work interact effectively and reliably.
Inside the 250 acres’ compound, there comes 5 major buildings; Body Assembling, Stamping, Engine & Transmission, Final Assembly, and Painting and Trim. With our thirst for innovation drives us to use new technology to build qualified products . Our building are funished with an error-proof “Automatic Line Control System”. This system aids the workers to increase the efficiency of production and to improve the quality. From the Shah Alam Manufacturing Complex, this new facility can produce multiple products that assemble the vehicles on 3 distinctive platforms.
