  • Every rubber part goes through a chemical reaction during its production, the curing step. It is a necessary step to achieve the desired final properties of a rubber part. This step needs to be fast and well-controlled at the same time. In the end this is usually the bottle-neck process in the manufacturing environment and a significant contributor the cost of a part. The starting point in determining optimal conditions is a rheometric experiment that determines a deformation force over time at a given temperature. When moving to the actual mold such an “online” observation is not possible. Additionally, temperature distribution throughout the mold and complicated sample geometries can make it a real challenge to find optimal cure conditions. We have applied a combined rheometry/swelling experiment that enables to establish a transfer function from the rheometer to the press. This allows to connect the equilibrium swelling of a production part to the corresponding point on an isothermal rheometer curve and enables to reach short cure times while maintaining the desired cure state.
