Recently, our company officially launched a new-generation integrated vacuum potting solution for motor stators. Focusing on material innovation and process optimization of two-component epoxy adhesives, we provide highly reliable and customized potting services for clients in industrial automation, new energy vehicles, servo motors and other fields, helping end products improve insulation class, heat dissipation efficiency and service life.
As global advanced manufacturing evolves rapidly toward miniaturization, high power density and long service life, motor stator windings face three core pain points: insulation breakdown, local overheating and vibration aging. Traditional atmospheric potting has a bubble rate of 5%–15%, which easily induces high-voltage short circuits and poor heat dissipation; vacuum potting reduces the bubble rate to below 0.1%, increases insulation resistance by 50%, and achieves withstand voltage above AC3000V, completely eliminating traditional process bottlenecks.
Our self-developed two-component epoxy adhesive features five core advantages: high insulation, high thermal conductivity, wide temperature resistance (-50℃ to 180℃), low shrinkage and anti-aging. It enables penetration into micro gaps as small as 0.3mm, forming a dense protective layer after curing that ensures electrical safety, structural reinforcement and efficient heat dissipation. Equipped with automatic vacuum potting lines and a full-process quality control system, we customize adhesive formulas and curing profiles based on customer stator specifications and working conditions. Sampling, small-batch and mass production are available with a stable yield rate above 99.5%.
Currently, the global market for two-component epoxy potting adhesives continues to grow, with strong demand from automotive and industrial motor sectors. Our solution has been successfully applied to stator potting projects for servo motors, new energy drive motors, industrial water pump motors and more, winning wide recognition from domestic and international clients. Going forward, we will continue to invest in material formulation and process R&D, launching new high-thermal-conductivity, low-VOC, bio-based eco-friendly products to empower high-quality development of the global advanced motor industry with innovative technology.
