Mingrui offers you a wide range of production facilities like
extrusion, injection moulding, pressing and casting. Depending on
product geometry and quantities, we will choose the suitable
technique for your products.For the final finishing of the parts we
use CNC machining centres, equipped with diamond tools in order to
meet high accuracies.
Our aim is to offer the ideal solution for any application. Our
engineers therefore offer custom solutions that range beyond our
existing product portfolio. With our well-equipped industrial
development facilities, we produce innovations that can be rapidly
commercially exploited.
