Casting Process Overview
With the advances in technology and the foundry industry, the rapid development of the different casting methods to prepare the content of the different mold. To apply the most extensive sand casting, for example, cast molding materials preparation, including the preparation and modeling made the two core tasks. Sand casting used to form the core made of various materials, such as foundry sand, molding sand binder, and other accessories, as well as by their preparation of the sand, core sand, paint and other materials, collectively referred to as modeling the task of molding materials prepared in accordance with castings requirements, the nature of the metal, select the appropriate raw sand, binders and accessories, and then according to a certain percentage of them as having certain properties of mixed sand and core sand. Equipment commonly used in sand sand grinding wheel machine, counter-flow sand machine and a trench-type sand mixer blades. The latter is designed for mixed-chemical self-hardening sand design, continuous mixing speed.
Modeling is based on making the core casting process requirements, a good modeling in determining the method of molding materials prepared on the basis of the. Casting accuracy and all the economic effects of the production process depends primarily on the working procedure. In many modern foundry, the shapes making the core are achieved mechanized or automated. Common core sand molding equipment made of high, medium, low molding machine, throwing sand machine, no box shoot squeeze molding machine, shoot core machine, cold and hot-box machine.
Casting from the mold pouring cooled after being removed, there are gate, riser, metal burr, Phi-feng Wo Hop mold lines, sand casting sand casting still clinging, it must be clean-up process. Equipment for such work, grinder, shot blasting machine, pouring riser cutting machines. Sand casting off the sand clean-up is the poor working conditions, a process, so in the choice modeling method, should be taken into account for the fall to create convenient conditions for sand clean-up. Some of castings for special requirements, but also by the casting post-processing, such as heat treating, shaping, anti-rust treatment, roughing and so on.
