SAVI precision injection-molded gear product line leverages the company’s many years of accumulated expertise in modification technology for self-lubricating engineering plastics. Using high-performance engineering plastic base materials, high-strength fibers and special solid lubricants are incorporated via polymer modification technology. Combined with precision injection molding processes, the resulting precision plastic gears feature self-lubrication, maintenance-free operation, low noise and long service life.

SAVI extends its well-established self-lubricating material modification technology from plain bearings to precision injection-molded gears, delivering an integrated maintenance-free transmission solution covering “bearings + gears”. This unique dual capability enables us to provide customers with complete maintenance-free solutions ranging from friction pairs to transmission chains, rather than standalone gear components.

SAVI offers fully in-house and controllable end-to-end services, covering material modification formula development, gear tooth profile design, precision mold manufacturing, gradient temperature-controlled injection molding, gear accuracy inspection and finished product assembly. This helps customers shorten time-to-market and reduce supply chain complexity.
