bm|t strengthens Ilmenau as a site for technology companies: QSIL obtains 7‑figure financing

  • 2015

QSIL (Quarz­schmelze Ilme­nau GmbH) – a lead­ing sup­plier of fused quartz prod­ucts – has closed a 7‑figure financ­ing round from a fund man­aged by bm|t (beteili­gungs­man­age­ment thürin­gen gmbh).

With the fund­ing, QSIL will expand its site in Ilme­nau, which cur­rently has more than 150 employ­ees. QSIL’s pro­pri­etary plasma fusion process makes it one of the only com­pa­nies in the world capa­ble of trans­form­ing up to 500 kg of crys­talline quartz sand into fused quartz by use of a sparked plasma arc heated to 2000 °C.

The tech­no­log­i­cal exper­tise, mar­ket posi­tion and sta­ble eco­nomic devel­op­ment of the com­pany have con­vinced us to invest in QSIL. We are glad that we can sup­port QSIL’s con­tin­ued growth at its Ilme­nau loca­tion with our financ­ing,” said Udo Werner, Man­ag­ing Direc­tor of bm|t.

Stephan Behr, Man­ag­ing Direc­tor of QSIL GmbH, sees the regional pres­ence of financ­ing part­ner bm|t as a spe­cial benefit.
