Abstract: The mechanical and hydraulic rigidities of twoplaten clamping systems and their influence factors were studied. It was found that it was very important to take the integral effect of the two rigidities into account during the design of clamping systems. It was different for the mechanical characteristics during the clamping and injection process, and the irreversible resilience of the mold impacted the secondary stretch of the mechanism.
