Stripping time
The stripping time (also called drawing time ) is a term used in foundry technology for cold-curing molding materials .
The stripping time is a time concept depending on the rate of hardening in a closed mold or core box. The time depends on the resin or hardener mixture and is usually between 10 minutes and several hours that a core remains in the core box until it can be switched off. The stripping time is over when the molded part can be removed from the mold and exposed to normal room air on all sides. At this point, the crosslinking must have progressed so far that no more deformation can occur.
The terms of time in the sequence of the workflow for cold-curing foundry mold materials are as follows:
- Mixing time
- processing time
- Workability time
- Stripping time
- Hardening time
- storage time
