Our history


SDI Plastics was established in 1993, by founder and co-director, Sewa Dhanda.

Starting the business with only two machines, Sewa had a lifelong ambition to operate his own plastics manufacturing business. He is a passionate enthusiast for solving complex problems and bringing new ideas to reality. Having in depth knowledge of the plastics injection moulding business and a burning desire to start his own company, Sewa’s fundamental philosophy is to believe in the ‘art of the possible’ and most importantly believe in yourself.

our history

Fast track to today, SDI Plastics is growing exponentially and expanded operations to Malaysia and China. Our manufacturing operations have fully equipped tool rooms, over 50 moulding machines, robotic equipment and an exceptional workforce, with a combined staff experience of over 150 years.
