In our facility we have full capabilities to turn your prototype of a rotary viscous damper or friction hinge into a final product. It is engineered manufactured, tested and packaged for immediate shipment to you. The full process from prototype to final product is done in house to assure the highest quality. All done in the USA from 100% USA made components. We believe this is the way to be sure that full control of all processes is held tightly.  visit as us at www.mmtech.us  to contact us for your latest project.
