Applying Scaling

To create the model, liquid plastic is injected into the mold tooling while the mold is closed. A cooling system in the core and cavity reduces the temperature of the hot plastic.

During cooling, the plastic shrinks. To account for shrink factor, you must scale the model slightly larger before you create the core and cavity. The shrink factor is a known value that is based on the type of plastic and the mold conditions. Use the Scale tool to apply a shrink factor to accommodate for the amount the plastic will shrink as it cools. The Scale tool scales only the geometry of the model. It does not scale dimensions, sketches, or reference geometry.

  1. Click Scale (Mold Tools toolbar).
  2. Expand Solid Bodies(1) in the FeatureManager design tree and select Draft2 as the Solid and Surface or Graphics Bodies to Scale in the PropertyManager.
    The body in Solid Bodies(1) assumes the name of the last feature applied to it.
  3. Select Centroid in Scale about.
    Scaling about the centroid ensures that all of the geometry is scaled proportionately. A model's centroid is based on its mass properties. You can display the centroid using the Mass Properties tool that measures and displays the density, mass, volume, and so on for the model.

  4. Select Uniform scaling.
  5. Set Scale Factor to 1.05.
