Clay Extruder for Chemical Engineering Applications
MPI locally fabricated and installed a stainless-steel clay extruder for the Department of Chemical Engineering at UET Peshawar, combining dual-auger mixing, vacuum de-airing, interchangeable dies, cut-off handling and safety controls.
Project in brief
A locally fabricated extrusion system for laboratory material processing
The requirement called for a robust, cleanable machine capable of mixing, vacuum de-airing and extruding clay through different die profiles. MPI fabricated the main structure, mixing chamber, augers, vacuum system, extrusion tooling and material-handling accessories as one coordinated unit.
The delivered configuration included limit-switch and overload protection, an oil-free vacuum pump, wired cut-off, receiving conveyor, collection chamber and the tooling required for supervised laboratory operation.
