settled and filtered as per the process mentioned above. After filtration and reclamation, fresh filler material should be added prior to use.
Recycling of the High Filled Waxes
Most filled pattern waxes contain more than 20 to 45 percent filler material. As a result, they are difficult to recycle since filtration is not possible. It is difficult to separate this density of filler material from the waxes. In this case separating the impurities with settling is the effective solution. Though we could not achieve a low ash content in these waxes after settling, we can definitely reduce the ash content and use these waxes for production for those jobs, where complete wax removal from the cavity is possible while dewaxing.
Steps for Recycling of the Filled Pattern Waxes
1. While continuously stirring, hold the wax at 1000 C to remove themoisture content of the wax.
2. After moisture removal, hold the wax at 1200 C. Stop the stirrer to allow the impurities to settle.
3. Provide sufficient time for the settling.
4. For this settling tank, two outlet vales should be provided. Valve No. 1 at the bottom of the tank. Valve No. 2 at 150 mm height from the tank bottom.
5. After sufficient time has passed to allow the filled wax to settle, remove the wax using valve No. 2.
6. This wax is passed through a magnetic separator to remove iron particles.
7. Filter this wax by a stainless steel wire mesh of 60 to 100 mesh.
8. Check the ash percentage and other properties. Adjust the properties and ash percentage by adding the fresh wax.
9. This Wax can be used for commercial jobs having maximum wax draining/dewaxing efficiency.
