6 Tips Compounding Customers Can Use To Maximize
Their Purging

• Though compounding is extrusion, its a unique
  enough subcategory of extrusion to worth its own
  debate. Compounding encompasses the inclusion of
  resins, stabilizers, fillers, reinforcements, and
  other colorants to a base resin.
• What distinguishes film extrusion from
  compounding is the number of additives introduced
  to the base resin this is where compounders add
  their value. A standard compounding line will
  have more than one port where additives are
  introduced to the melt. These ports are areas of
  low melt pressure and are usually tough for
  purging compounds to clean.
• Due to these differences challenges,
  compounding is a subject thats presently
  inadequately served by commercial purging
  compounds. Below we would like to share a few
  tips with compounding customers to maximize their
  purging
• Knowing the capacity of your barrel before
  purging will let you cautiously regulate the
  quantity of purge being employed usually 1 to
  three barrels full of products are adequate. This
  will let you regulate inventory, and lessen
  outlays.

• Slowly rotate the crew to fill the flights. As
  soon as the purge begins to kick out, amplify
  screw speed to maximize the performance of the
  purging compound. Mechanical purges are most
  efficient at the highest safe screw speeds, where
  agitation turbulence are exploited.
• Disco Purge After the barrel flights of the
  screw are full of purge, stop screw rotation, and
  allow the melted purge to sit settle into any
  dead spots for 4-5 minutes. Then start screw
  rotation once more, repeat multiple times. The
  dramatic changes in pressure agitation let
  purges best perform their task.
• Vents are low-pressure areas that decrease the
  efficacy of purging instantly after the vent
  location. Plug the vents manually at the time of
  purging to amplify local pressure. If plugging
  the vents isnt feasible, feed the purge into the
  vents at the same time its being fed into the
  hopper.
• Mixing areas are usually quite tough to clean. In
  this scenario, a chemical purge might be an
  excellent option. Alternately, make use of the
  disco purge method with mechanical purges to
  make the most of cleaning in this area of the
  screw.
• Ensure that the purge compound you buy is rated
  to use with the least clearance in your die. The
  majority of purging compound manufacturers will
  have the right grade for your clearance needs.
