High-quality products are inseparable from regular mold cleaning and maintenance. Shuliy dry ice cleaning machine can quickly and deeply clean all kinds of molds and equipment without using chemical solvents at all and without causing secondary pollution. So, how is dry ice blasting applied to the PET mold industry?
Why is the dry ice cleaning so popular now?
Dry ice blast cleaning, also known as cold spray, uses compressed air as the power and carrier, and uses dry ice particles as accelerated particles. It is sprayed onto the surface of the object to be cleaned by a special dry ice blasting machine.
高速运动的固体干冰粒的动量变化（Δmv）、升华、融化等能量转换，将被清洗物体表面的污垢、油渍、残留杂质等迅速冻结，从而从而凝结、脆化、剥离，同时随气流除去。
干冰清洗不会对被清洗物体表面，特别是金属表面造成任何损伤，也不会影响金属表面光洁度。
Dry ice cleaning and PET mold manufacturing
采用传统的手工清洗方式，需要几个小时才能清理完144个孔。如果需要拆下模具进行清洁，甚至可能需要几天的时间。只能清洗模唇和模芯，不能清洗排气孔和模腔。
The Shuliy dry ice blaster machine is used to clean the PET molds, and the hot molds can be cleaned directly without cooling. The cleaning time only takes about 25 minutes, which can greatly improve the cleaning efficiency.
采用干冰清洗方法可快速清除模唇、排气孔、模芯、型腔上的污渍，且不会损坏模具。这可以大大节省清洁时间、减少停机时间并提高生产率。并且可以大大提高清洗效果，提高成品率。
