Cavity weight result

The cavity weight result shows the calculated weight of each cavity in a multi-cavity mold.

This result is generated for the following mesh types:

• Midplane
• Dual Domain
• 3D

for the following molding processes:

• Thermoplastics injection molding
• Thermoplastics overmolding
• Co-injection molding
• Bi-injection molding
• Reactive molding
• Microchip encapsulation
• Thermoplastics microcellular injection molding

and for analysis sequences that include:

• Fill

Using this result

The cavity weight result shows the weight of the cavity, at the time the result was written. It can be animated, and changes with time. The result is written even when there is only one cavity in the model. This result is a time series result, written at several time steps, so you can also create an XY plot over time.

For dual domain and midplane models it is plotted on the triangular part element or part beam and excludes the feed system.

For 3D models the cavity weight result is plotted on tetrahedral elements, so cavity elements should be assigned the element type Part (3D). Part insert or core elements are not be included in this result. The feed system can be modeled as either beam elements, or as tetrahedral elements with the property type hot runner (3D), or cold runner (3D).

Things to look for

• Every part in a multi-cavity mold containing identical parts should have the same weight. Differences show that some parts are not filling; check the runner system.



• Check the weight of each component in the mold and compare against the expected weight. Consider changing the material, or changing the design, if the result differs from expectation.
