China coupling facoty make mask machine to fight against COVID supported by Foshan govenment .It is a coupling fctory with 19 years rich ecperience.they have full professional machine equipment ,during the 2003,they hade made mask machine for xiantao ,the non-woven fabric town .Which is knows for its disposable mask.So we do believe they can make good quality mask machine .
As we all know flexible coupling well, it is necessary for us to know the working principal of flexible coupling. Invention of flexible coupling dates back many centuries. Even though the flexible coupling’s mechanism seems simple, the physics behind this mechanism are rather complicated and interes
Flexible couplings are simple and relatively inexpensive devices which aren’t difficult to install or maintain, yet many of which fail prematurely. These failures of flexible coupling also happen despite the devices being specially designed to tolerate slight misalignment and to cope with the tough
