A recently filed patent (Publication Number: US20230311436A1) describes a method for manufacturing an actuator. The method involves assembling the actuator and then curing it using a predetermined heating profile. The heating profile consists of at least one heating phase and at least one temperature maintenance phase.

In the heating phase, the actuator is heated at a rate between 80°C and 200°C per hour. Each heating phase follows this heating rate. Alternatively, the heating rate can be between 90°C and 110°C per hour. The heating profile includes a first and a second heating phase, with the first phase having a longer duration than the second phase. The first heating phase lasts between 1.0 and 1.5 hours, specifically 1.25 hours, while the second heating phase lasts between 0.1 and 0.2 hours, specifically 0.15 hours. At the end of the first heating phase, the actuator reaches a temperature of 120°C, and at the end of the second heating phase, it reaches a temperature of 135°C.

The heating profile also includes a first and a second temperature maintenance phase. The second temperature maintenance phase has a longer duration than the first phase. The first temperature maintenance phase lasts for 3 hours or between 2.7 and 3.3 hours. The second temperature maintenance phase has a duration in the range of about 8 to about 9 hours.

The patent also claims an actuator that is manufactured using the described method.

This patent presents a method for manufacturing actuators that involves a specific heating profile. By following this method, manufacturers can ensure the proper curing of the actuator. The heating profile includes specific heating rates, durations, and temperature maintenance phases. These parameters are designed to achieve optimal results in terms of the actuator's performance and durability. The patent also claims the actuator itself, indicating that it is a product of the described manufacturing method. This patent could be of interest to companies involved in the production of actuators, as it provides a detailed and specific method for their manufacturing process.
