Should Poketone be dried before injection molding?

Before injection molding, dry Poketone for 2hr~4hr at 80℃ to reduce the water content to below 0.2%.
Should Poketone be cleaned after being used?

Shutdown Procedure for Polyketone

At the completion of the molding run at normal barrel temperature (about 235~250℃),
all traces of POKETONE should be thoroughly purged at processing temperature from
the barrel with purging material such as PCTG, high density-PP, HDPE, GPPS or other
commercially available purging compound.
After the purge appears clean, the screw is left in the forward position.
Barrel and nozzle heats can then be turned off.

(Can be purged several times at higher barrel temperature of 270~280℃ for better
cleaning of POKETONE, then purge again at the normal barrel temperature (about 240℃)
till purging clears.)

Guide Line for downtime during injection molding

☞ Stop within 20 minutes :
   1. Stop molding process while maintaining cylinder and Hot runner temp.
   2. Purge out several times before re-started molding

☞ Stop from 20 minutes within 2 hours :
   1. Purge out all the rest of Poketone material inside cylinder and hot runner manifold
   2. Decrease the temperature from current temperature to 20~40℃ on cylinder
      (hot runner temp) and stopped molding process while turning on heater.
   3. When re-started operation, please increase the temperature to the norm and
      purge out several times when reached to the temperature

☞ Stop from 2 hours within 12 hours :
   1. Purge out all the rest of Poketone material inside cylinder and hot runner and
      lower the temperature to 170~180℃ on cylinder(hot runner temp) then stopped
      molding process while turning on heater.
   2. When re-started operation, please increase the temperature to the norm and
      purge out several times when reached to the temperature
      (when increase the temperature, firstly increase cylinder temperature then later
       increase hot runner temperature)

☞ Stop more than 12 hours :
   1. Purge out all the rest of Poketone material inside cylinder and hot runner manifold
   2. By using purging material(PCTG, High-density PP, HDPE, GPPS, etc),
      keep purging out until inside of cylinder is completely cleaned then stopped
      molding operation

☞ For better cleaning :
   1. After purging enough using purging material, increase barrel temp. 30℃
      (about 270~280℃) then purge again several times using purging material.
   2. Decrease barrel temp to normal, then purge again.
