PRODUCT INFO
Specific Instructions for Injection Molding
- Empty the barrel feed throat of polymer.
- Reduce screw speed to 10-15 rpms.
- Screw back pressure should be reduced to zero.
- Barrel and nozzle assembly should be in position to take air shots.
- Place cardboard box over nozzle discharge.
- Pour ½ - 1 ounce of CA250 per inch of screw diameter into the screw - 2” screw equals one to two ounces of CA250.
- Follow with four ounces of polymer per inch of screw diameter - 2” screw equals eight ounces of polymer.
- Repeat #6 and #7 until CA250 exits the nozzle, keeping the feed throat empty at all times to reduce screw slippage.
- Continue #7 until the screw, barrel and nozzle are clean.
- Purge until CA250 is no longer evident.
- Resume production.
Proper safety precautions for the equipment require monitoring the back pressure and motor load.
Proper safety precautions for personnel require training procedures that emphasize liquids at elevated temperatures and pressure.
Keep personnel away from all exit ports.
