Issue Solution example

Weld Lines

Description: Weld lines are actually more like a plane than a line that appears in a part where molten plastics meet each other as they flow from two different parts of the mold.

Causes: Weld lines are caused by the inadequate bonding of two or more flow fronts when there is partial solidification of the molten plastic.

Remedies:

1. Raise the temperature of the mold or molten plastic.
2. Increase the injection speed.
3. Adjust the design for the flow pattern to be a single source flow.
4. Switch to a less viscous plastic or one with a lower melting temperature

Short Shot

Description: As the term implies, short shots can be described as a situation where a molding shot falls short. This means that the molten plastic for some reason does not fully occupy the mold cavity or cavities, resulting in a portion where there is no plastic. The finished product becomes deficient because it is incomplete.

Causes: Short shots can be caused by a number of things. Incorrect calibration of the shot or plasticizing capacities can result in the plastic material being inadequate to fill the cavities. If the plastic is too viscous, it may solidify before fully occupying all the cavities and result in a short shot. Inadequate degassing or gas venting techniques can also result in short shots because air is trapped and has no way to escape; plastic material cannot occupy the space that air or gas is already occupying.

Remedies:

1. Select a less viscous plastic with higher flowability. This plastic will fill the hardest-to-reach cavities.
2. Increase mold or melt temperature so as to increase flowability.
3. Account for gas generation by designing the mold so that gas is not trapped within the mold and is properly vented.
4. Increase the material feed in the molding machine or switch to a machine that has a higher material feed in the event that the maximum material feed has been reached.
