PURGING GUIDELINE

 

Step 1: Maintain processing profile for resin in the machine. (minimum temperature 135°C)

Step 2: Empty the screw and barrel of residual resin.

Step 3: Place PurgeMax® directly into hopper and follow with purging material immediately. *

Step 4: The Purging process can be done by purging or injection. **

Step 5: Maintain continuous purging until resin appears natural and clean.

Step 6: The 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 (layering) and repeat until entire dosage has been added then charge the barrel with purging resin.

 

Note: A small amount of smoke may appear during purging. Although not very common, it is a normal condition.
