The ability to more rapidly prepare the components for inspection and testing ensures that Metric Automotive Engineering is able to speed up the quotation time.

The cleanliness of engine components prior to inspection, testing and assembly is critical to the subsequent successful remanufacturing of diesel engines. Metric Automotive Engineering recently invested in an MOT 750 ultrasonic component cleaning machine to provide faster turnaround times to the benefit of its customers.

Metric Automotive Engineering is a family-owned and operated company that remanufactures complete diesel engines and components. The company has built a reputation for superior service and a customer-centric attitude. Regular feedback from customers and research into new technology provide Metric Automotive Engineering with a sustainable business model.

“The ability to more rapidly prepare the components for inspection and testing ensures that we are able to speed up the quotation time to our customers. This results in reduced downtime of customer machines, with the concomitant improved productivity and enhanced return on investment,” Andrew Yorke, operations director at Metric Automotive Engineering, says.

The Tierratech MOT 750 ultrasonic cleaning machine operates on the principle of releasing ultrasonic high frequency waves (20 kHz and greater) into the liquid in which the components are immersed. The ultrasonic energy produced breaks the mechanical and ionic bonds that exist in the dirt and debris surrounding and within the components.

The components are bombarded with ultrasonic waves over 40 000 times every second, producing a highly efficient micro-bush effect for maximised cleaning effort. The system is so effective that it is able to penetrate nooks and crannies that are inaccessible using other cleaning media.

“Not only can we guarantee customers improved lead times on their remanufactured components and engines, but we are also exhibiting our commitment to environmental stewardship by using such a green cleaning methodology. The MOT 750 consumes minimal cleaning materials, since it operates at a very low concentration of about 2%. In addition, we are able to drastically reduce the amount of water used in the cleaning process, since all components are now immersed in the unit’s fluid container. Water filters are installed in a closed circuit to provide increased lifespan and operability of the unit,” Yorke points out.

Another benefit accruing to Metric Automotive Engineering is the elimination of a component cleaning operator. “The components are simply loaded into the cleaning bath of the MOT 750, the system is activated and the responsible person can then proceed with other tasks. In addition, by minimising the use of cleaning chemicals, we are able to ensure a safer working environment. Our employees can now avoid contact with hazardous products such as solvents, acids and highly alkaline detergents,” Yorke adds.

“The MOT 750 will result in a time saving of approximately 80% on previous cleaning methodologies. This time saving will be passed on to our customers who can then expect a much faster turnaround time on their engines. In addition to the time saving, this highly efficient cleaning mechanism provides both Metric Automotive Engineering and our customers with the confidence that even complex components are completely clean, for a more reliable engine” Yorke concludes.
