Ru-CORES: Removes Adhesive Residue from Cores used in Foundries
 Metal Foundries across the world use 2 major process for making moulded products,
Cold Bake process & Hot Bake process
Cold Bake Process
The process involves,
1. Preparing the paste of Phenol based aldehyde adhesive, sand and other forming material.
2. This paste is poured in the Core and left to set and harden.
3. Once it is hard, the mould is removed from the core.
While the Core is separated from the Mould, some amount of hardened Adhesive sticks on to the walls of the core and over a period of time, the shape and accuracy of the core deteriorates. This adhesive is very difficult to clean and has to be scraped off by hand thus scratching the core and affecting the finish of the mould.
At Ru Chem, where innovation is the key to progress, a product has been developed and tested which resolves this cleaning problem smoothly and effectively. The savings in time and wastage of cores makes it an economical addition to the cleaning process.
RU-Cores ( NB ) is a water based, non hazardous, non flammable liquid. It is environment friendly with minimal ammonia content. It just required spraying the liquid on the core, wetting it properly, wait for 5 minutes and wipe off the adhesive. That's it! No scraping, scratching required.
Hot Bake Process
IN Hot Bake Process, the only difference to the process is that the paste is compressed into the core and baked to form a hard mould. Here the adhesive sticking on the surface of the core gets burnt and leaves a hard to clean residue.
RU Cores ( B ) is a hydrocarbon based product which can remove this residue without the need for scraping or sanding and thus retain the shape and size accuracy of the core.
Note: RU Cores ( B ) is flammable in nature.
Ru-Cores as industrial cleaner, designed to:
Give absolutely dry surface.
Helps to control water pollution.
Facilitates saving in terms of Time, Energy, Resource and Money.
Being water based it is non-flammable and can be used safely
Although in is required in much less quantity, it cleans up effectively
