Analysis Of The Casting Process Of Epoxy Resin Insulators

The pre-treated insert should first be installed into the mold, and then a proportionally prepared epoxy resin mixture should be added. Casting should then be completed under vacuum or normal pressure, followed by a curing stage to create a one-piece insulator. This process allows the liquid resin to flow and fill the mold cavity, penetrating into the micro-spaces between the insert and the resin, avoiding the formation of bubbles and cracks. high voltage epoxy resin Vacuum casting is performed using molds or similar tools, requiring the viscosity after heating to be below a certain value to facilitate flow.

The casting process for high voltage standoff is typically considered the standard procedure: mold preheating, ingredient mixing, degassing, mold pouring, curing, and demolding. Mold temperature, resin formulation, and degassing status are all critical parameters.
