Advanced part testing helps innovative oil filter development

Solvay Specialty Polymers : 08 November, 2014  (Application Story)
Solvay Engineering Plastics has been collaborating with Mahle in the development of oil filter modules using Technyl polyamide resins. The current glycol flow test benches at the company’s Technyl Innovation Centre in Lyon, France, are capable of testing as many as six parts at a time in temperatures of up to 135C and with oil under static pressure. Now, a new glycol bench will offer the possibility to perform, in parallel, high flow glycol and oil circulation tests at even higher pressures and temperatures.
 
With its three business units Engine Systems and Components, Filtration and Engine Peripherals, as well as Thermal Management, Mahle ranks itself among the top three automotive systems suppliers worldwide. Technyl compounds are used on more than 15 different current Mahle oil modules. All of them have undergone rigorous testing, including long-term ageing resistance in glycol flow, according to major OEM specifications, and have been fully validated. 
 
“Our part testing capabilities are designed to help develop more efficient thermal management components,” states Laurent Perret, Application Laboratory Manager for Solvay Engineering Plastics. “From February 2015, we will be able to manage two flows of media simultaneously, at 150C with pulsated pressure of up to 10 bar on the glycol side and 16 bar on the oil side.”
 
In addition – and mandatory not just for oil modules – Solvay also offers vibration testing in dedicated shaker equipment furnished with a thermal chamber for temperatures ranging from -35 to +180C and capable of test frequencies from 5 to 2000Hz. Other available equipment includes a dynamic tensile device for final part testing with a load up to 30kN and hot air pulsated pressure bench reaching air temperatures of up to 220C.
 
“Reliable oil management is critical in modern automotive engineering and must ensure that lubricants are properly supplied, cleaned and thermally managed,” says Ralf Kiemlen, Head of Development Oil Filtration Systems at Mahle Filtersysteme.
