Kerke started from the extruder parts trade, then we have our factory to produce screw elements and sell to extruder factories, in 2009, we started to produce extruders by ourselves. Now many other manufacturers still buy core parts from outside, but we still insist on producing core parts by ourselves, because we can control the quality and send all parts to our customers fast.
