Diesel engine and com- ponent remanufacturer Metric Automotive Engineering is set to commis-sion the largest pressure tester in the country.
The company says this will effectively make it the only company in the country capable of pressure-testing the biggest cylinder heads on the market with accuracy.
The Carmec PTR 1600XLH tank pressure tester for cylinder heads and blocks supplements Metric’s existing pressure testing capabilities.
“The commissioning of an additional machine enables us to boost productivity and to provide faster reporting to our customers about the condition of their cylinder heads,” says Metric Automotive Engineering operations manager Andrew Yorke.
He notes that the latest engineering designs have seen heavy-diesel engines revert-ing to large single-piece multi-cylinder heads.
“This development prompted us to invest in the most appropriate testing equipment available on the market to ensure we provide an accurate testing service,” he says.
Yorke adds that accuracy is important because the design of the latest cylinder heads incorporates water, oil and fuel chambers in the same head.
“The advantage of this pressure tester is that the cylinder heads are immersed in water and thermostatically maintained at a temperature of 80 °C, which simulates the engine operating temperature.
“The tester’s automated fixturing allows for the vertical movement of cylinder heads in and out of the pressure testing tank by means of a hydraulic system, as well as a motorised full 360° rotation inside the tank, making it a simple task to check all sides of the cylinder heads from every angle.
“This rotation takes place while the head remains fully immersed, enabling our technicians to conduct a comprehensive leak test,” he explains.
Yorke says the addition of the new machine forms part of the company’s continuous programme of reinvestment in equipment, technologies and personnel to stay at the forefront of the industry in which it operates.
