electrical insulation board Manufacturing Process

Material Preparation:
This includes selecting the base material, such as fiberglass, phenolic resin, epoxy resin, or composite materials. It depends on the desired electrical and mechanical properties of the final product.
Resin Mixing and Impregnation:
Mix resins according to specific formulation and viscosity requirements. This process ensures a proper bond between the resin and the substrate.
Layering and Pressing:
Many layers of impregnated material are stacked together to achieve thickness and strength. Stacked layers may also include conductive or non-conductive sheets or films for specific electrical properties. We then place the layered assembly into a hydraulic or heat press.
Heat Curing:
The stacked and pressed assembly is subjected to heat and pressure in a curing process. This step promotes resin cross-linking, resulting in the hardening and consolidation of the board structure.
Trimming and Finishing:
After the last step, we trim the insulation board to the required size using a cutting machine or CNC equipment. Then we grind and polish the edges of the boards to ensure uniformity and precision in the final product.
Surface Treatment:
The insulation boards may undergo additional surface treatments depending on the application requirements. This may include sanding or applying special coatings to improve surface smoothness, electrical performance or adhesion.
Quality Control and Testing:
This may involve visual inspections, dimensional inspections, electrical testing and other performance evaluations. Verify insulation resistance, dielectric strength, thermal conductivity and other relevant properties.
Packaging and Delivery:
We use safe packaging and then ship them to customers or stores for future distribution.
