The spring unit (10) for tooling and equipment manufacture comprises a housing with a cylinder (1) with a coaxial pressure rod (2) guided in the cylinder (1) having a larger-diameter section at one end and projecting from the cylinder (1) at the other. At the outlet end of the cylinder there is an outlet element (3) through which the pressure rod (2) passes while at the opposite end there is a closure (6). In the housing there is a spring system which push the pressure rod (2) axially outwards against the outlet element (3) and against which the pressure rod (2) can be pushed into the housing. The cylinder (1), the outlet element (3) and the closure (6) are surrounded by a plastic jacket (12) forming the outer periphery of the housing. |
