Cleaning plastic extrusion tooling during the disassembly process
lengthens the service life of your tooling, helps to reduce scrap and
helps you to maintain tighter tolerances on your final product.
Today, there are various options for cleaning plastic extrusion tooling.
They include:

  • Ovens
  • Fluidized beds
  • Propane torches
  • Cryogenic cleaning

Each method can be effective at removing the plastic, unfortunately,
each can also remove steel, damage the tooling or otherwise
compromise the integrity of the metal. For example, ovens are very
effective at vaporizing the melt, however, with repeated use they can
change the molecular structure of the piece and pit thinner areas.
This may result in leakage between critical components and higher
scrap rates. The other methods for cleaning plastic extrusion tooling
have similar concerns. In each case, we recommend a close look at the
cleaning method and tools used to ensure that damage is minimized.

B&H Tool Co. recommends cleaning plastic extrusion tooling during
the disassembly process. Cleaning your tooling at the extrusion line,
while it is hot, lessens the risk of damage to the tooling and reduces the
amount of time required for the traditional methods mentioned above.

With proper training and the right cleaning tools, operators can
increase the life of your tooling while reducing scrap and maintaining
the quality of your output. As efficiency increases, productivity goes up
and downtime is minimized. Here is a list of proper cleaning tools
and the comprehensive cleaning procedure in English.
