The applicability of casting prg materials in different types of castings has its own characteristics.
For large castings, casting prg materials have certain advantages. It can have good fluidity through reasonable formula and process, and can fully fill the cavity of large molds, thereby ensuring the integrity of castings. At the same time, its good bonding performance helps to maintain the shape stability of large castings during solidification and reduce the occurrence of defects such as deformation. However, relatively speaking, for some super-large castings, it may be necessary to more strictly control the solidification time and shrinkage of the material to ensure the quality of the casting.
In terms of small precision castings, the high-precision molding ability of casting prg materials makes it more applicable. It can accurately replicate the details of the mold, achieve high dimensional accuracy and surface finish, and meet the strict requirements of small precision castings for precision. For example, in the casting of small parts of some electronic equipment, PRG materials can well ensure the dimensional accuracy and surface quality of parts, which is conducive to subsequent assembly and use.
Complex structure castings are also one of the applicable fields of casting prg materials. Due to its good flexibility and adaptability, when casting castings with complex shapes such as complex inner cavities and thin-walled structures, it can better conform to the shape of the mold and avoid problems such as insufficient filling or stress concentration. For example, in the casting of some complex structural parts in the aerospace field, PRG materials can help produce precision castings that meet high strength and lightweight requirements.
However, casting prg materials are not suitable for all types of castings. For some castings with extremely high temperature resistance requirements, such as some high-temperature alloy castings, PRG materials may need to be specially modified or used in combination with other high-temperature resistant materials to meet the use requirements. In addition, in some castings that need to withstand extremely high pressure or impact, its mechanical properties may need to be further improved or special processing processes may be used to enhance its applicability.
