However, undesired adhesion phenomenon makes molded part difficult to be released from tool surface during ejection stage of the injection molding process.
Serious mold adhesion phenomenon occurred in TPU injection molding process.
It was the adherent slime (i.e., slime in intimate association with the bacterial cell wall as shown by electron microscopy) only, which was responsible for resistance to multiple antibiotics and for the adhesion phenomenon
observed in the quantitative slime test.
In the die cutting sector have the "wear" complex as an abrasion phenomenon, adhesion phenomenon
, tribo-chemical reaction, surface destruction etc.
As the friction between the surface and the fluid develops, there is also the natural tendency of the fluid to resist separation of its own continuum mass, creating the adhesion phenomenon
called viscous drag.
While some studies have examined mold adhesion phenomenon
in IC packaging industry (1), (2), few have considered mold adhesion in the injection molding process.
Both TPU and skin have demonstrated absence of adhesion phenomenon
. Moreover, no influence of loading speed was found on this phenomenon.
This analysis has attempted to view the adhesion phenomenon
in terms of general dielectric components, with attention to the specific example of metal to dielectric adhesion.
