USA’S LEADING COST AND QUALITY PERFORMANCE PURGING SOLUTION FOR INJECTION MOLDING AND BLOW MOLDING

Extrusion

PurgeMax Plus Purging Guideline for Extrusion.

Dosage refer to printing on the box bottom, pls use PurgeMax Plus to run the
cleaning/testing, it will show you the good result.

  • Step 1: Maintain processing profile for resin in the machine. (minimum temperature 100°C)
  • Step 2: Empty the screw and barrel of residual resin.
  • Step 3: * Place PurgeMax Plus directly into hopper (by layering) and follow with purging material immediately.
  • Step 4: Continuous purging until resin appears natural and clean.
  • Step 5: Purging process is complete, resume with standard procedures for next job.

* Follow the dosage chart or you may double the quantity. This is because barrel capacity are commonly larger than injection molding’s.
E.g. screw diameter is 115mm = 8 packets + 4 (total 12 packets); initiate purging process and observe result. If purging resin is very dirty, user can repeat the purging process.
* For extreme/stubborn carbon, mix 2 packet PurgeMax Plus per Kg purging resin and start purging process.
Note: User doesn’t have place all packets at once, user may consider “layering” Purgemax
Plus in barrel.
Note: For twin screw purging, user may add 50% to the dosage required.

Purging Guideline – Vertical Injection

Standard purging process does not require PurgeMax mixing with purging resin. Soaking prior to
purging is not required also.

  • Step 1: Maintain processing profile for resin in the machine. (Minimum temperature 100°C)
  • Step 2: Empty the screw and barrel of residual resin.
  • Step 3: * Place PurgeMax directly into hopper and follow with purging resin immediately.
  • Step 4: Purging process can be done by purging or injection.
  • Step 5: Continuous purging until resin appears natural and clean.
  • Step 6: Purging process is complete, resume with standard procedures for next job.

* With applications that require more than one PurgeMax (refer PurgeMax Usage Chart) , place
one PurgeMax into the hopper and follow with a small amount of purging resin and repeat until
entire dosage has been added then charge the barrel with purging resin.
