Step 3: Assembling the Parts
-
Cut a piece of silicone coated fabric that is a little bit bigger than the actuator top part.
-
Mix a small batch of EcoFlex and pour a little onto the surface.
-
Use a gloved finger to even out the liquid material over the whole surface - in a thickness of approx. 1 mm.
-
Place the actuator top part into the uncured silicone, with the open side facing down. Gently press it into contact with the material
-
Place a rectangular piece of wood (or something similar) atop the actuator top part to gently weigh it down thus ensuring contact with the strain limiting bottom during curing
-
Cure the acutator by putting it in the oven for approx. 35 mins. at 80°C or leaving at room temp. for 4 hours - the latter will create the most strongest bond between the two parts
-
Once the silicone has cured, cut of the excess fabric along the sides of the actuator with a pair of scissors or by using a ruler and an X-Acto knife
