This two-cavity aluminum mold offers durability and repeatable results for Ned-style baits. The CNC engineering ensures consistent wall thickness and sharp detail across injections, while compatibility with common plastisol injectors makes it a versatile option for hobbyists and professional shops alike. The 2.5-inch length is well-suited for bass fishing and Ned profiles, delivering reliable performance with repeated use.
Zoom Salty Super Fluke 4” Two Cavity
Features: Solid Soft Lure Mold Build For Durability And Unlimited Injections, CNC Engineered High Quality Aluminum, Injection: Standard 5/8″. Compatible With Most Plastisol Injectors
The Zoom Salty Super Fluke mold is designed for robust, high-detail fluke-shaped baits. Its two cavities maximize output while maintaining accuracy. Aluminum construction minimizes wear, and the standard 5/8-inch injection nozzle compatibility makes it easy to integrate with a wide range of injectors. Ideal for producing soft plastics that emulate baitfish with a natural profile in the 4-inch range.
Smallie Beaver 3.5” Two Cavity
Features: Solid Soft Lure Mold Build For Durability And Unlimited Injections, CNC Engineered High Quality Aluminum, Injection: Standard 5/8″. Compatible With Most Plastisol Injectors
The 3.5-inch Smallie Beaver mold focuses on compact bass-tail profiles. Its two-cavity design increases production velocity while preserving consistency of detail. Aluminum ensures fast heat transfer and tight tolerances, essential for plump tails and realistic action in soft plastics. Compatible with a wide range of injectors, this mold suits small- to mid-sized lure production.
Googan Bandito Bug 4” – CNC Aluminum
Features: ✓ INNOVATION AIR VENTS, ✓ ALUMINIUM 7075T, ✓ VERY HIGH DETAIL
The Bandito Bug mold blends high-detail fidelity with engineered air venting to control air pockets during injection. The 7075T aluminum provides excellent strength-to-weight ratio and heat resistance, supporting consistent fills for a variety of color and texture finishes. With a 4-inch length, it is suitable for producing life-like bug profiles that appeal to many freshwater species.
Three Cavity Gulp Shaky Worm 5” – Aluminum
Features: Injection: Standard 5/8″. This size ensures compatibility with most injectors, DETAILED BAIT DESIGN. Fine level of detail comparable with aluminum molds and far better than silicone molds
The three-cavity 5-inch Gulp Shaky Worm mold is tailored for complex worm profiles with shallow ribs and subtle tapers. Aluminum construction supports high-fidelity detailing, while the three-cavity design helps maximize output. Compatibility with standard injectors keeps setup straightforward for varied production needs. This mold suits a range of bass and predator-focused soft plastic applications.
Two Cavities Spunk Shad 3.5”
Features: Injection: Standard 5/8″. Material: Engineered stone with stone powder and polymers for low porosity and durability, Smart air vents to ensure full details fill
This spunk shad mold emphasizes robust material construction and a detailed shad silhouette. While the description mentions engineered stone, the listing pairing with aluminum molds highlights performance expectations for sharp ribs and precise tail shapes. The vent design minimizes air traps, helping to create consistent, detailed baits across batches.
Yama Senko 5” – Three Cavity Aluminum
Features: PROTOTYPE: Yama Senko 5”, INJECTION: Standart 5/8″. This size unsures compatibility with most injectors., Lubrication: not required. Unlike stone molds, the aluminum molds does not require lubrication
The Yama Senko three-cavity mold focuses on a classic Senko-style profile with ample surface area to hold color and texture. Aluminum construction ensures quick heat transfer and durability across repeated injections. Unlike some stone-based molds, aluminum does not require additional lubrication, simplifying maintenance and improving cycle times.
Buying Guide: Key Considerations For Aluminum Lure Molds
- Material and durability: Aluminum molds offer excellent heat transfer and longevity. Look for CNC-machined finishes and high-grade alloys (such as 7075T) for repeated use and consistent results.
- Number of cavities: More cavities increase output but may impact mold weight and heat distribution. Choose based on production goals and injector capacity.
- Injection compatibility: Most listed products mention Standard 5/8″ injections. Ensure your plastisol injector matches this size to avoid leaks or incomplete fills.
- Vent design: Air vents help prevent air pockets and ensure full detail filling. Vent quality can directly affect realism in fins, ribs, and tails.
- Detail and texture: Detail fidelity varies by mold and design. For bass and predator lures, prioritize high-detail profiles and accurate anatomy.
- Maintenance: Aluminum molds can be maintenance-intensive if not cleaned properly. Wipe away excess plastisol and inspect for burrs after each session.
- Compatibility and workflow: Consider whether you need two or three cavities, and whether your production workflow benefits from multi-cavity designs or single-cavity precision molds.
- Price and availability: Aluminum molds span a range of prices. Balance upfront cost with expected output and durability for your fishing goals.
- Weight and handling: Heavier aluminum molds require proper supports during injection. Ensure you have a stable workstation and secure handling practices.
In summary, aluminum molds for soft plastic baits deliver robust performance, precise detailing, and reliable repeatability for anglers and lure makers. The selections above emphasize a balance of cavity counts, profile variety, and advanced features like air vents and premium alloys to support a range of lure designs. When choosing, align your choice with your target species, injector compatibility, and production tempo to optimize results.
