Issue Solution Example:

Vacuum Voids

Description: Vacuum voids are pockets of air trapped within or close to the surface of an injection molded prototype.

Causes: Vacuum voids are often caused by uneven solidification between the surface and the inner sections of the prototype. This can be aggravated when the holding pressure is insufficient to condense the molten plastic in the mold (and thereby force out air that would otherwise get trapped). Voids can also develop from a part that is cast from a mold with two halves that are not correctly aligned.

Remedies:

1. Locate the gate at the thickest part of the molding.
2. Switch to a less viscous plastic. This will ensure that less gas is trapped as air is able to escape more rapidly.
3. Increase holding pressure as well as holding time.
4. Ensure that mold parts are perfectly aligned.

Surface Delamination

Description: Surface delamination is a condition where thin surface layers appear on the part due to a contaminant material. These layers appear like coatings and can usually be peeled off (i.e. “delaminate”).

Causes: Foreign materials that find their way into the molten plastic separate from the finished product because the contaminant and the plastic cannot bond. The fact that they cannot bond not only has an affect on the appearance of the prototype, but also on its strength. The contaminant acts as a localized fault trapped within the plastic. An over-dependence on mold release agents can also cause delamination.

Remedies:

1. Pre-dry the plastic properly before molding.Increase the mold temperature.
2. Smooth out the corners and sharp turns in the mold design to avoid sudden changes in melt flow.
3. Focus more on the ejection mechanism in the mold design to reduce or eliminate the dependence on mold release agents
