4″ Slim Swimbait Mold

4″ Slim Swimbait Mold

Precision Aluminum Injection Mold by BassMold

The BassMold 4″ Slim Swimbait Mold is designed to produce sleek, paddle-tail swimbaits with natural swimming action and consistent body shape. This slim-profile swimbait is ideal for matching smaller forage and excels in clear water, pressured fisheries, and situations where subtle presentation is key.

Machined from solid aluminum, this mold provides excellent heat transfer and long-term durability for repeat production cycles. Each cavity is precision cut to ensure smooth fills, sharp tail definition, and easy demolding with minimal flashing. The slim body design allows for easy injection and reliable tail movement, creating a smooth kicking action at slow and moderate retrieve speeds.

This mold is ideal for producing swimbaits for jig heads, weighted hooks, and finesse swimbait rigs. By adjusting plastic softness and salt content, anglers can fine-tune tail action, sink rate, and durability to match water temperature and fishing conditions. Whether you’re producing baits for personal use or small-batch production, this mold delivers professional-quality swimbaits with every cycle.
