Percentage molten layer result

The Percentage molten layer result is generated from a Cool analysis using 3D analysis technology and shows the percentage of polymer that has not frozen at the time specified.

This result is the inverse of the Percentage frozen layer result.

Using this result

3D parts often have thick sections that are difficult to cool. Some sections may freeze quickly, while thicker sections take longer to freeze. This result allows you to see which sections of the part are cooling more slowly.

The percentage molten layer should be very low, indicating that the part has cooled sufficiently. If the part is ejected before it has been cooled sufficiently in the mold, the part will cool outside of the mold and will be prone to warpage.

Note: A thick part should be sufficiently sound, structurally, to withstand the ejection process. Depending upon the ejection procedure, no more than 20% molten at ejection is a reasonable guideline.

Things to look for

• This result can be used to check whether the polymer has frozen off sufficiently before the part is ejected.
• Check the inverse result, the Percentage frozen layer result.
