Dry Ice Core Box & Mould Cast Cleaning

See Other Applications

Safely clean core boxes & mould castings, while reducing downtime, improving product quality and eliminating the risk of damage

Dry ice blasting quickly and safely removes the buildup on core boxes and mould castings without creating secondary waste. The process is non-abrasive and will not damage screens, vents or the tooling. Cleaning core boxes and mould castings with dry ice cleaning leads to a significant reduction in production downtime and scrap rates.

Buildup of resin and sand on core box vents prevents core material from solidifying, and often causes vent clogging, which reduces product quality and creates scrap. Traditional cleaning methods are very slow, ineffective, can damage tooling and destroy vents on the core boxes. Dry ice blasting is extremely effective in cleaning both core boxes and moulds – the process can clean any type of mould and a variety of mould finishes up to and including A1 surfaces and textured surfaces.

The Cold Jet expertise and deliverables extends far beyond core box & mould casting cleaning with dry ice. Our expert dry ice technicians are highly knowledgeable and are always happy to answer your dry ice questions. Including:

How Does Dry Ice Blasting Work?

There are three primary factors that contribute to the dry ice core box & mould casting cleaning process. The factors include Pellet Kinetic Energy, the Thermal Shock Effect, and the Thermal-Kinetic Effect. In order to better understand the cleaning practice, the process can be broken down into three stages – Impact, Cold, Expansion (ICE).

IMPACT – The impact of pellets creates a kinetic energy effect. The soft dry ice accelerated by compressed air at supersonic speeds.

COLD – The cold temperature of dry ice creates a thermal effect. The low temperature of dry ice (-78.9°C /-109°F) causes the bond to break between the contaminants and the surface.

EXPANSION – The expansion of the dry ice pellets. Dry ice pellets sublimate on impact, expanding in size and removing the contaminants.

Why Should I Use Dry Ice?

Due to the unique characteristics of dry ice, it has many benefits that make it an extremely favourable option when compared to cleaning alternatives. The main benefits of dry ice blasting include, but are not limited to:

  • Cleaning equipment in place with little or no disassembly
  • Dry cleaning with no water or chemicals
  • Reducing downtime associated with cleaning
  • Cleaning without secondary waste
  • Improving product quality and reducing scrap
  • Eliminating equipment wear and tear
  • An environmentally responsible cleaning method

How Does Dry Ice Blasting Save Time?

Dry ice blasting, particularly for core box & mould casting cleaning, is incredibly time-efficient when compared to other cleaning methods. This is due to a significantly faster process that leads to minimised downtime and an increase in productivity. A reduction in labour and the lengthy processes that typically come with core box & mould casting cleaning mean that the process of cleaning with dry ice blasting is incredibly time saving and efficient. The lack of clean up, secondary waste and elimination of the need to relocate and disturb equipment also contribute to dry ice blasting saving significant time and labour.

How Is Dry Ice Eco-Friendly?

Believe it or not, dry ice blasting is the ideal solution for those looking for an environmentally friendly cleaning solution for foundries, core boxes and mould castings of industrial equipment. Here’s why:

Dry Ice Blasting Eliminates Harmful Secondary Waste

When the dry ice impacts the surface being cleaned, it sublimates – turning directly from a solid to a gas—and thus does not produce secondary waste. Similar cleaning techniques leave behind a residue that must be cleaned up afterwards, along with the offending contaminant. This media can become hazardous and create downstream contamination and harm the surrounding area and installations. Say goodbye to secondary wastes with dry ice blasting for core box & mould casting equipment cleaning.

Dry Ice Uses Reclaimed CO2

All dry ice used in the dry ice blasting process for core box & mould casting cleaning is made from reclaimed CO2, which is a by-product of other industrial processes. This CO2, which would have otherwise been released into the atmosphere, is captured and given new life as dry ice. Dry ice blasting does not produce or produce additional CO2.

Dry Ice Blasting Is Non-Toxic

Dry ice blasting for core box & mould casting cleaning is non-toxic and eliminates the need for chemical solvents in industrial cleaning processes. The dry ice used in the dry ice blasting process is a food grade media and is EPA, FDA and USDA approved for use around food manufacturing. It is colourless, tasteless, odourless and non-toxic.

Is Dry Ice Just Used for Core Box & Mould Cleans?

No – dry ice blasting is incredibly versatile and can be used for a wide range of applications. Due to the plethora of benefits of using dry ice blasting, the practice can also be used for a wide range of solutions, including:

  • Coating & Corrosion Removal
  • Composite Tool Cleaning
  • Core Box Cleaning
  • Equipment Cleaning
  • Historical Restoration
  • Core box & mould casting cleaning
  • Part Finishing
  • Surface preparation
  • Weld Line Cleaning
  • Dry Ice Manufacturing for Airline Catering
  • Dry Ice Cooling in Food Processing

Does Dry Ice Blasting Leave A Residue?

No – dry ice blasting does not leave residue or waste when removing contaminants from core boxes and equipment moulds. Dry ice sublimates upon impact with the surface being cleaned, which results in no secondary waste, no residue and no introduction of moisture. This eliminates extra clean-up, disposal of secondary waste streams and additional cleaning preparation, such as masking delicate sensors or wrapping electronic components before cleaning. Our process significantly reduces the duration of cleaning projects and the resulting shutdowns.

With no secondary waste produced, this also means equipment can be cleaned while online and still operating.
