High-voltage insulating parts are applied in high-voltage power transmission and distribution, and have very high requirements for insulation grade and mechanical strength. Solid resins and curing agents are used as insulating materials, and the functions and performance of the casting equipment are also required to be high.
Process features
Solid resin is melted and fed by pouring the material. The raw material bucket is heated to melt it.
Solid curing agents can be removed from the bag in a dust-free manner or directly sucked into the dissolution tank through a suction pipe under vacuum
The packing is bagged in small or ton packages without dust to prevent dust from polluting the workshop. The packing is stirred and heated under vacuum to fully degas and dehydrate the material
Resin and curing agent are automatically and continuously fed. The materials are mixed into two non-reactive A/B components. The material is automatically measured according to the ratio, and the feeding is precise and stable
The single-component materials are stirred and heated under vacuum, and the umbrella-shaped film degassing/continuous online degassing technology is adopted to quickly remove the water vapor from the materials
The A/B components are automatically measured and conveyed according to the ratio. The A/B components are mixed by dynamic or static mixing methods, and the mixed materials are conveyed to the vacuum casting tank product mold for vacuum casting and impregnation
Vacuum casting equipment Product advantages
Environmentally friendly design, energy conservation and emission reduction, and reduction of labor intensity
The materials are automatically fed, weighed, mixed, conveyed and cast into shape
The powerful control system monitors the equipment status and process flow throughout the entire process, and records production-related parameters in real time, which can be viewed at any time
The servo metering pump is used for material proportioning measurement, which is more accurate and stable. It adopts a silicon carbide ceramic piston with a wear-resistant and pressure-resistant design, ensuring a long service life
