Insulation parts are important components to prevent short circuits in transformers. Their performance and quality directly affect the reliability and service life of the transformer.

At present, transformer winding insulation parts are usually made by hand. On the one hand, manual operation has low production efficiency and is easily affected by human factors, resulting in the inability to effectively improve production efficiency. Manual operation also makes it difficult to ensure the uniformity of the insulating material throughout the manufacturing process, which will lead to safety hazards such as unstable performance of the insulation parts during use.

Some insulating parts are also manufactured by injection molding, but the density and uniformity of the insulating materials of the insulating parts are still limited due to the certain injection pressure of the injection molding method.
