Zinc Alloy Die-Cast Housing for Fishing Reel Body

The main body of a rotary reel featuring streamlined side plates and an arched line guard, typically serving as the load-bearing frame for lure or sea fishing reels. This component integrates internal cavities for gearbox installation, mounting positions for side adjustment knobs, and bottom handle connection shaft holes. It presents a high-gloss metallic finish, designed to support precise internal transmission mechanisms and resist corrosion in seawater environments.

Such aesthetic components demand high precision in mold runner design and molding shrinkage control to ensure full filling of thin-walled areas and natural transitions at R-angles, avoiding casting defects like shrinkage and flow marks. Given the multi-point assembly requirements, we strictly control the coaxiality of central bearing seats, the positional tolerance of threaded holes, and the dimensional consistency of external contours. This ensures that gap and flushness after assembly meet kinematic standards while preventing later deformation risks caused by internal stress.

Leveraging our expertise in zinc-aluminum alloy die-casting and IATF16949 quality system certification, we provide one-stop services from mold development and precision die-casting to CNC post-processing and surface treatment. For these fishing tackle accessories, we independently perform deburring, tapping, and mirror-level polishing. We conduct 100% inspection of key mating dimensions using equipment such as Zeiss CMMs to ensure consistency in batch delivery, meeting the strict quality and lead-time requirements of both domestic and international orders.
