If vents are not incorporated into the mold design, the adhesion of the TPE to the substrate can be critically affected in specific areas of the part where air is trapped in the cavity during injection.
As the TPE melt is injected into the mold cavity, the air in the cavity must be able to effectively exit the tool.

Accounting for 25% or more of observed failures in the field, it is believed that ESC is the leading cause of plastic component failure.3 To better understand the environmental contribution of stress cracking, it is helpful to examine stress cracking in air (creep).

The thermal conductivity of conductive plastics is not as high as that of metal, but conductive plastics can be just as effective as metals in thermal management, transferring heat by conduction (which depends on the material) and convection (which depends on the design of the system and the flow of air or liquid around the polymer part).
All vents should allow trapped air and gasses to escape to the area outside the mold.
