SUNPASS small winding machine can produce basic type and wound gaskets with inner ring (need to be modified), and the diameter of wound gaskets produced by it is between 18MM-200MM. Driven by a variable frequency controlled gear motor. Especially equipped with a demoulding device without an inner ring gasket, there is no need to repeatedly load and unload the mold core. The simple and controllable outer diameter size control device can improve the production efficiency of gaskets.
