Epoxy Resin Sleeve Production Process Under Pre-impregnation And Wrapping Construction Method

In the prepreg winding process, epoxy resin and reinforcing fibers are first mixed in a specific ratio to form a uniform prepreg layer. This layer is then wound onto a specialized mold, ensuring the fibers adhere evenly to the mold. The winding speed is matched to the mold rotation speed to achieve a stable interlayer structure. Appropriate control of the resin viscosity improves the wetting properties between the fibers and the resin.

After the winding is completed, epoxy resin cast bushing enters the curing stage. Under constant temperature and time conditions, the resin gradually cross-links and hardens, forming a tube with a consistent structure. This process balances material flowability and forming stability, ultimately giving epoxy bushing manufacturer good geometric consistency and overall density.

To ensure the controllability of the epoxy bushing for transformer production process, manufacturers must strictly monitor the resin formulation and curing conditions during wet winding. By properly setting the number of winding layers and the curing environment, a sleeve that meets the design requirements can be stably obtained.
