Potted Exothermic Sleeve
In the steel and cast iron casting industries, sleeves or prefabricated feeders are used as a feeding system. When the molten metal enters the sleeve chamber, a chemical reaction begins that releases a lot of heat. After the reaction is complete, the remaining materials act as a thermal insulator and keep the heat concentrated in the feeder. The sleeve keeps the molten metal ready and available for feeding for a limited time. This feature creates a suitable thermal gradient between the part and the feeder, which results in directional solidification. To order and purchase a potted exothermic insulation sleeve, contact the sales experts of Avangard Company.
The use of potted or conical exothermic sleeves improves the performance of cast parts and makes it possible to reduce costs and eliminate shrinkage defects. In calculations, it is recommended that a maximum of 33% of the molten metal volume be considered for feeding the parts. In summary, potted exothermic sleeves play a very important role in improving the quality of the part and ensuring its soundness, and with careful calculations and their use, desired results can be achieved in the casting process.
Types of Potted Exothermic Sleeves
The widespread use of potted exothermic sleeves in the casting process can help improve performance and reduce costs. Increasing the range of melt delivery by the sleeves leads to a reduction in production time and costs. By correctly selecting the type and size of the feeder, it creates a suitable thermal gradient from the feeder to the cast part. As a result, by using potted feeding sleeves, costs associated with the finishing section and post-casting processes can also be reduced.
