Common Issues in PET Bottle Preform Injection Molding
PET bottle preform injection molding is a good method. But it has its own troubles. Here are some frequent problems in making PET preforms and ways to fix them:
1. White Marks on the Bottom of PET Preforms
Cause: Not enough hot runner heat and low material heat.
Solution: BJY PET Mould suggests better heat keeping, more heat in the hot nozzle, and higher material heat. Also, speed up injection and slow the cooling to help fix this.
2. Non-Transparency of PET Preforms
Cause: Not enough drying of raw stuff, bad mixing, and too thick walls.
Solution: To fix this, BJY PET Mould stresses drying materials for at least four hours. Raise material heats too. And keep a steady injection amount. By drying the material to under 0.02% water, makers can get the wanted clear look.
3. Silver Stripes or Yellowing in Preforms
Cause: Break down of plastic in the molding step.
Solution: BJY PET Mould advises lower drying heat, longer drying time, change in injection speed, and control of material heat. This stops plastic break down and keeps the clear state of the preforms.
4. Air Bubbles in PET Preforms
Cause: Not enough drying of materials before molding.
Solution: BJY PET Mould proposes better drying steps, higher material heats, and slower screw speed. This gets rid of air bubbles and makes sure smooth preforms without flaws.
5. Irregular Ring Grooves Inside PET Preforms
Cause: Water vapor builds up inside the mold core.
Solution: To stop this, BJY PET Mould advises better drying in the work area, higher cooling water heat, and full drying of molds before use.
6. Defective Injection Point or Cold Flow Issues
Cause: Bad mold design and wrong injection settings.
Solution: The fix is in better mold design and change of injection settings. This includes faster injection speed and longer injection time. BJY PET Mould’s careful molds give better hold over these parts.
These are only a few cases of troubles makers deal with in the PET injection molding process. By picking BJY PET Mould’s top gear and custom fixes, firms can cut flaws, raise making speed, and give good PET bottles each time.
