The economic advantages of the precision production process for the counterweight castings of loaders mainly rely on this process. The commonly used sand mold forming and core-making equipment includes high-pressure, medium-pressure and low-pressure molding machines, sand polishing machines, no-box injection molding machines, injection molding core-making machines, cold and hot core-box machines, etc. In many modern loader counterweight factories, mold forming and core-making have been mechanized or automated. The production of loader counterweight blocks is not merely a process of melting the metal and then pouring it into molds to form. It also includes the smelting process. The molten metal must meet the specified requirements in terms of temperature and chemical composition. Therefore, in the smelting process of loader counterweight blocks, quality control tests for the purpose of quality management are carried out. Only when the liquid metal meets all the specified indicators can it be allowed to be poured.
Sometimes, in order to meet the high standards, after the metal liquid of the loader's counterweight block is extracted from the furnace, it still needs to undergo various furnace-outside treatments such as desulfurization, vacuum degassing, furnace-outside refining, nurturing or transformation treatment. The commonly used equipment for melting metals include electric arc furnaces, blast furnaces, induction furnaces, reflector furnaces, and resistance furnaces, etc.
The commonly used loading machine sand-mixing equipment includes wheel-type sand-mixing machine, counter-flow type sand-mixing machine, and blade-slot type sand-mixing machine. The latter was revised for mixing chemical hard sand and is characterized by continuous mixing and high speed. The core-making of the loading machine's weight blocks is based on the requirements of the loading machine's weight-mixing process, and is modified in the method of core-making. It is carried out on the basis of preparing the core-making materials.
