On Wednesday, 11 September 2024, the University of Johannesburg (UJ) celebrated the professorial inauguration of Professor Madindwa Mashinini, an esteemed academic in Mechanical Engineering and Acting Vice Dean of Teaching and Learning.

The event, attended by notable guests including Prof Bongani Ngqulunga, Senior Executive Director for University Relations, and Prof Daniel Mashao, Executive Dean of the Faculty of Engineering and the Built Environment, marked a significant moment in Professor Mashinini’s illustrious career.

During the event, Professor Mashinini delivered his inaugural address titled “Advanced Materials and Sustainable Processes for a New World”, where he highlighted the growing importance of sustainable manufacturing processes. Following his presentation, Professor Munish Gupta from Opole University of Technology in Poland delivered a brief response, underlining the global relevance of Prof Mashinini’s research and its potential impact on sustainable manufacturing worldwide.

Advancing engineering through sustainable innovation

In his presentation, Professor Mashinini emphasised the need for advanced manufacturing techniques that promote sustainability and efficiency within the engineering sector. He explored cutting-edge welding technologies, such as friction and laser welding, which enable the joining of difficult-to-weld materials like titanium composites and high-entropy alloys (HEAs). These processes improve material performance, durability, and reduce energy consumption, aligning with global sustainability goals.

Professor Mashinini also discussed the transformative potential of additive manufacturing (3D printing), which allows for the production of complex geometries with minimal waste, reducing the carbon footprint of manufacturing processes. His work highlights the integration of artificial intelligence and advanced machining methods to optimise surface quality and energy efficiency when working with high-performance materials such as titanium alloys.

A distinguished career in Mechanical Engineering

Professor Mashinini’s academic journey has been marked by numerous contributions to the field of mechanical engineering. He served as Head of the Department of Mechanical and Industrial Engineering Technology at UJ from 2017 to 2024 and currently holds the position of Acting Vice Dean of Teaching and Learning within the Faculty of Engineering and the Built Environment.

Recognised as an established researcher by the National Research Foundation (NRF) with a C2 rating, Professor Mashinini has published over 60 peer-reviewed articles, authored 11 book chapters, and presented extensively at conferences. His expertise spans welding, composite materials development, additive manufacturing, and advanced machining processes.

As a professional member of the Engineering Council of South Africa (ECSA) and the South African Institute of Mechanical Engineering (SAIMechE), he continues to play a pivotal role in advancing engineering standards and education both locally and internationally.

The inaugural lecture offered a glimpse into the future of sustainable engineering, with Professor Mashinini’s work paving the way for more environmentally conscious and innovative approaches in the industry.
