Injection Moulding

Why Cleaning with Dry Ice is the preferred method of cleaning plastic moulds.

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 hard-to-access tool crevices.

What can be cleaned with dry ice blasting?

  • Release agents
  • Overspray
  • Hardened plastic
  • Mix of all used materials and substance
  • Moulds, screws, mixers etc

Plastic, rubber and styrofoam injection moulding industries can benefit from dry ice cleaning.

There is often no need to remove the moulds from the plastic injection moulding machine. There is no need to cool down and reheat machinery as machinery can be cleaned while still hot allowing production to commence quicker.

What normally takes hours can be done in minutes.

Regular cleaning reduces the time needed for each cleaning operation and more importantly, rejects are reduced to a minimum.

No water or chemicals are used to get a superior quality clean.

Advantages of dry ice blasting in injection moulding industry:

  • No damage to mould -longer lifetime- reduced cost.
  • Reduction in Labour cost.
  • Preventing damage to the finished product surface – lowering waste and scrap rates.
  • No secondary waste.
  • No water residue.
  • 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 mould surface dimensions.
  • Lower rejects as mould is 100% clean.
  • Removes hard-to-see contamination.
