1. Mechanical manufacturing field
In the mechanical manufacturing scenario, the performance requirements for Casting PRG are mainly concentrated on strength and wear resistance. Since mechanical parts usually need to withstand large loads and friction, Casting PRG needs to have high strength to ensure that it will not break or deform during operation. For example, in the manufacture of engine parts, PRG materials must be able to withstand high temperature, high pressure and wear caused by high-speed operation. At the same time, for precision mechanical parts, the dimensional accuracy requirements are strict, which requires Casting PRG to have good casting processability, which can ensure the dimensional stability and surface quality of the castings and reduce the workload of subsequent processing.
2. Aerospace field
The performance requirements for Casting PRG in the aerospace field are extremely demanding. First of all, lightweight is one of the key requirements. In order to reduce the weight of the aircraft, improve fuel efficiency and carrying capacity, Casting PRG should have a lower density. At the same time, high strength and high toughness are also essential performance requirements to ensure that the parts can maintain structural integrity in extreme flight environments, such as high air pressure changes and drastic temperature changes. In addition, corrosion resistance is also crucial, because the aircraft will be affected by various corrosion factors when flying in the atmosphere for a long time. Moreover, this field has extremely high requirements for the reliability of materials, and any minor defects may lead to serious consequences, so Casting PRG must undergo strict quality inspection and control.
3. Construction field
In the construction field, Casting PRG is mainly used for some special building components or decorative parts. For this type of application scenario, appearance quality and weather resistance are important performance requirements. Casting PRG should have good surface flatness and finish to meet the aesthetic needs of building decoration. At the same time, weather resistance requires that the material can maintain stable performance in a long-term outdoor environment and resist erosion by natural factors such as ultraviolet rays, rain, wind and sand. In addition, the construction field is usually more sensitive to cost, so Casting PRG also needs to have certain cost advantages while ensuring performance to improve its competitiveness in the construction market.
4. Electronic equipment field
In the field of electronic equipment, the performance requirements of Casting PRG mainly focus on thermal conductivity and electromagnetic shielding. With the miniaturization and high performance of electronic devices, the heat dissipation problem has become increasingly prominent. Therefore, Casting PRG needs to have good thermal conductivity to effectively dissipate the heat generated by electronic components and ensure the normal operation of the equipment. At the same time, in order to prevent electromagnetic interference, Casting PRG should have certain electromagnetic shielding performance to protect electronic equipment from interference from external electromagnetic signals. In addition, for some portable electronic devices, the material is also required to have a lighter weight to improve the portability of the device.
