How to Create a Soft Grip
One of the more common reasons to utilize the overmolding process is to create a soft grip. Pulling from the example used
below, the green part is used functionally as a twist-able nozzle that will help direct the flow of a liquid. However, in this case,
the plastic chosen to facilitate the flow and to keep its chemical resistance for lasting part integrity happens to be very rigid and
hard to the touch; not ideal for tightening and loosening with human hands.
The solution is to design for an overmolded rubber-like grip to aid the user in the twisting of this product.
But, tactile functionality is not limited to human grip. Overmolding can also be cleverly used to add rubber-like grips to
clips designed to grab inanimate objects.
