Easy collapsibility coated sand: it is for non-ferrous metals (especially aluminum) is not easy to sand casting and developed a coated sand. The sand also has good strength has excellent low temperature collapsibility. With its production of non-ferrous metals (aluminum, copper alloys, etc.) coated sand casting regeneration, does not require re-heating the casting sand, just after pouring the casting to cool for 24 hours, you can SHAKERS. Centrifugal Casting coated sand: the coated sand suitable for centrifugal casting process, it can be used to replace the production of centrifugal casting and other coating materials based on iron pipe diameter size and technical requirements are different, can be processed into different performance centrifugal casting coated sand. Differs from other types of coated sand, is the density of the larger number of coated sand coated sand recycling plant, low-fat and fat volume of gas slowly handmade wet coated sand: The wet coated sand compressive strength can be adjusted within 0.1-0.3MPa. Stored for more than three months, or the system is suitable for hand molding core (like tung oil sands Hop fat sand), after stripping at room temperature, the type (core) in a heated oven or oven coated sand recycling machinery, heating temperature 250-350 ℃, heating time 3-10min, type (core) after curing with high intensity, low-fat volume, a small amount of creep-shaped, non-hygroscopic characteristics. The coated sand suitable for single pieces and small batch production of high precision casting coated sand regeneration companies, particularly suitable for township enterprises to adopt. It is worth noting that, in the type (core) heat curing, must wait to put the time to reach the required temperature of the heating furnace, the furnace temperature and avoid heating coated sand recycling company, coated sand regeneration, Qingdao, Qingdao Heng Heng Machinery Limited. Qingdao Heng Machinery Co., Ltd. (www.thjidian.com) strong, credible, Shandong Qingdao Cleaning equipment industry has accumulated a large number of loyal customers.
