Injection Molding


Dry ice blasting
Dry ice blasting is the fastest way to remove a tarnished release agent from inside a plastic injection mould press and it is also the best way to remove 100% of the contaminant, especially in the hard to access valleys and crevices of the tool.

What can be cleaned with dry ice blasting?

  • Release agents
  • Overspray
  • Hardened plastic
  • Mix of all used materials and substances

Dry Ice cleaning of moulds
Dry Ice cleaning of moulds, screws, mixers ect.  in plastic and styropor injection industries can benefit from dry ice cleaning.

In situ on site cleaning without  having to remove the moulds from the plastic injection moulding machine. Cleaning when hot is an advantage to the cleaning with dry ice. Quick return of equipment back into production. No need to cool down and reheat. What normally could take hours can be done in minutes.

Regular cleaning reduces the time needed for each cleaning operation and more important reduces the rejects to a minimum.
No dust, water or chemicals used to get superior finish and quality.Advantages of dry ice blasting in plastic industry:
No damage to mould – longer lifetime – reduced cost

Dry Ice cleaning

  • Reduction in Labour cost
  • Preventing damage to the finished product surface – lowering waste and scrap rates.
  • No dust.
  • No water residue.
  • In site cleaning
  • Reduced time and labour cost as mould in cleaned in-situ
  • Dry ice also cleans slots and screen vents at the same time.
  • No changes in the mold surface dimensions.
  • Lower rejects as mould is 100% cleaned
  • Cleans what is not visible

How Does Dry Ice Blasting Clean?

The Dry Ice Pellets are propelled at supersonic speed by compressed air. Upon impact, the Dry Ice creates a “micro-thermal shock” (caused by the extreme cold of the pellet @ -79.5° C), which breaks the bond between the coating and the substrate. The high-pressure air stream removes the dirt from the surface and the Dry Ice pellets vapourise (sublimate) before your eyes.
