To increase productivity and enhance quality, liquid carbon dioxide or liquid nitrogen can be used instead of cooled air in the plastic industry’s blow moulding processes.
Benefits of blow moulding:
- Better productivity through more effective utilisation of machines
- Improved dimensional stability of the moulded parts is improved
- Shortened time cycle
- Enhanced aesthetical qualities of the product
The method is most suitable for cooling of thick-walled parts with long cycle and cooling times.
