Technology Features of DAIWA 2019 Castizm 25 15PE
TOUGH DIGIGEAR (Aluminum)
DAIWA’s DIGIGEAR is a gear system realized through a manufacturing technique that accurately shapes the form derived from numerical analysis of power transmission efficiency by computer. Instead of casting, the gears are processed using forging, which provides higher strength, and then the gear teeth surfaces are smoothed through ultra-precision machine cutting, allowing for efficient power transmission. TOUGH DIGIGEAR enhances this by increasing the surface area of the gear teeth and the radius of the gear, further improving durability and strength, resulting in a smoother winding experience.
MAGSEALED
DAIWA's MAGSEALED technology is designed to prevent water, salt, and debris from entering the reel, using magnetic fluid to form a barrier that protects critical components like bearings, line rollers, and gears from saltwater. DAIWA adapted magnetic fluid technology initially developed by NASA for dust protection in hard drives used in space. Unlike traditional rubber seals that increase handle rotation friction, the magnetic fluid is held in place by a magnetic field, reducing friction and enabling smooth operation. This technology enhances the reel's durability and performance, significantly improving reliability in harsh fishing environments without requiring meticulous maintenance.
AIR ROTOR
AIR ROTOR is designed to achieve the ideal spherical shape for a rotating body. Through high-precision rigidity analysis, it maintains the same level of rigidity as traditional rotors while achieving significant weight reduction and lower inertia. The reduction in inertia allows anglers to stop and wind the reel at will, providing excellent responsiveness and a lighter, smoother winding experience.
ZAION
ZAION is a top-tier carbon material created by DAIWA using proprietary technology to mold a special resin densely woven with carbon fibers, a process that is extremely difficult to achieve. It combines exceptional lightness and strength, making it the pinnacle of DAIWA's carbon materials. This superior performance is a privilege reserved only for the highest-end models.
