The Kwame Nkrumah University of Science and Technology (KNUST) has developed a locally-made machine designed to test the strength of various materials.
The high-precision material testing machine, named TechStress TS-50, was designed by researchers from the Mechanical Engineering Department of the university.
This innovation aims to eliminate the need for importing foreign-made machines for testing materials such as fibres, metals, and plastics.
Background and development
The lead scientist, Prof. Yesuenyeagbe Fiagbe, told GraphicOnline in a telephone interview that the project was inspired by the need to study the properties of fibres in Ghana.
"Initially, the team thought about buying a testing machine, but they realised they had the knowledge to build one locally. This led to the creation of a highly accurate, flexible testing machine that can be used in various industries," he explained.
He added that “this machine can test not only fibres but also metals and plastics, giving accurate measurements of their strength and properties.”
According to Prof. Fiagbe, the machine’s precision is as high as 0.0004, making it capable of detailed testing even for the smallest fibres.
The machine is equipped with advanced sensors, a touch screen, and electronic components, making it efficient and user-friendly. Its high accuracy and ability to collect and store data make it an important tool for industries that require rigorous material strength testing, such as cable and wire manufacturing.
“For industries that produce cables and wires, it’s important to ensure materials meet the required standards over time. This machine provides a reliable way to perform these tests, making it essential for quality checks,” Prof. Fiagbe said.
Beyond its industrial applications, the machine is also expected to benefit educational institutions.
“This machine will be useful in science labs, especially for experiments on material strength and stretching,” he noted.
Prof. Fiagbe expressed appreciation to Mr. George Ansong, a Research Assistant, who played a key role in the machine’s development.
