As a mechanical engineer reading this blog you should be aware of ambient temperature and it’s effect on the motion of a MMT rotary damper. We usually test the designs in a chamber setup to simulate the customers application. Even though we use a viscous compound that is very tolerant of temperature changes, exact changes in damping motion should be carefully examined to validate customers expectations. Also keep in mind, that structural components in the system are also affected. Metals and plastics expand and contract at extreme temperatures and we design with those temperature variables in mind. So if you have an application for a friction hinge or rotary viscous damper call us at 203-406-7900. Our website is
