I was working on a heavy duty piece of rotary equipment recently and realized it could benefit from a friction hinge or a rotary viscous damper. The safety guards for this machine are 1″ thick aluminum and swing like a pickup trucks back door. It could slam on a body part or even damage itself or the test material. The cost of a damper or friction hinge relative to the cost of medical or broken machine costs is small. So if you are designing industrial equipment remember safety is job number one.Our products can help you there. See us at www.mmtech.us
