QSIL acquires Philips facility

We are pleased to announce that QSIL acquires Philips’ fused quartz and special glass operation in Winschoten, Netherlands. The corresponding purchasing agreement has been signed at the beginning of July 2016 and the closing of the transaction is planned in the third quarter of 2016.

Through the announced acquisition QSIL further expands its technology basis and acquires an absolute quality leader in the production of tubes and rods out of fused quartz.

Stephan Behr, CEO at QSIL explains: „Now we have the capability to offer all our customers in the lighting industry as well as in semiconductor or chemical industry the whole spectrum of rods and tubes – produced by either using the one step or the two step tubing process, whatever brings the best advantage for the individual customer.”

The future QSIL Group will employ about 300 people and will generate sales of about 65 million euros. By this means QSIL catches up with the big competitors in the market of fused quartz.
