Products Description
APG Mold(Automatic Pressure Gelation Mold) is a precision mold specifically designed for the APG epoxy resin casting process, widely used in the production of medium and high voltage electrical insulation components.
The mold works together with APG casting machines to ensure stable pressure injection, accurate gelation control and consistent product quality, making it a critical tooling component in modern electrical insulation manufacturing.
Our APG molds are designed for long-term industrial operation, focusing on precision, durability and process repeatability.

During the APG process:
Mixed epoxy resin is injected into the closed mold cavity under pressure
The mold maintains a controlled temperature to trigger resin gelation
Continuous pressure compensates for material shrinkage
The final product cures with uniform structure and minimal internal stress
The mold plays a decisive role in heat distribution, pressure balance and surface quality.
