FRP rod preparation is an early but critical step in composite insulator manufacturing. The rod is the load-bearing core, so surface and dimensional quality affect later processes.
Rod preparation is linked to silicone rubber bonding, end fitting assembly and final mechanical test results.
Cutting and dimension control
Rod length and diameter must match product drawings.
Dimensional variation can affect molding, fitting assembly and test results.
Surface preparation
Sanding or grinding improves surface consistency for bonding and assembly.
Contune offers FRP rod sanding equipment for production planning.
Cleaning and inspection
Dust, oil or surface defects should be controlled before molding.
Inspection records help trace product quality issues.
Connection with final tests
Poor rod preparation may appear later as mechanical weakness or bonding problems.
