FatFish V20-6C Bait Mold
The FatFish V20-6C mold provides a durable platform for unlimited injections, supporting repeated use without significant wear. A smart air vents design helps release trapped air, ensuring liquid plastic fills all mold details for a crisp, lifelike appearance. The overall design emphasizes fine detailing that approaches the quality seen with aluminum molds, while avoiding the higher cost and complexity of metal tooling. This mold is well-suited for fast production runs of small swimbaits in 2-inch sizes.
Key features include a robust build for long-term use and precise venting to reduce air pockets. The balance between detail and practical production makes this mold a strong option for hobbyists who want consistent results across batches. For anglers, the resulting lures typically exhibit better tail action and head contour fidelity due to the tight seal and grid-like cavity layout.
Do It Mold SBH-5-A Swimbait Head Jig
The SBH-5-A system centers on a swimbait head jig design that accommodates several common weights (1/4, 3/8, 1/2, 5/8, 3/4 oz). This mold is typically paired with specific WDB1000 and 32786BLN eye hardware options or similar items for the complete build. While the package may not include every component, the Do It Mold lineup is known for reliable geometry and compatibility with standard swimbait materials. It’s especially suitable for people who want to experiment with tail-propulsion dynamics and balanced head shapes.
The SBH-5-A mold emphasizes precision in head geometry and cavity alignment, helping ensure consistent lure casts and predictable buoyancy. When used with appropriate silicone or soft plastic formulations, the result is a sturdy, ready-to-pin lure that resists warping during cooling. This makes it a practical choice for anglers who value repeatable results and straightforward setup.
Premium Soft Plastic Lure Mold – 3″ Swimbait, 6-Cavity
This CNC-machined mold is designed to produce 3-inch swimbaits with six cavities and requires no release oil. The heat-resistant material withstands up to 200°C (392°F), enabling reliable demolding and reduced risk of bubble formation. The smooth finish and tight seal reduce flash and improve overall yield. Buyers benefit from consistent cavity dimensions and a straightforward demolding process that minimizes sticking or tearing of soft plastics during removal.
No oil or release agents are needed, which simplifies cleanup and reduces material costs over time. The design emphasizes a high tolerance for heat and a precise seal, enabling efficient production of uniform lures. This is a good option for makers seeking a durable, low-maintenance mold that still delivers precise, detailed baits in a small-to-mid-size range.
Premium Soft Plastic Lure Mold – Zako Swimbait 4″ (4 Cavities)
Like the 3-inch model, this 4-inch Zako swimbait mold emphasizes CNC precision, a tight seal, and a heat-tolerant design. The four cavities provide a balanced production option for mid-sized swimbaits while maintaining a consistent finish and minimal release agent requirements. The no-oil-needed approach aligns with cleaner workflows and faster demolding, helping pool makers and hobby crafters achieve reliable results across batches.
The mold’s emphasis on durability and precision makes it well-suited for higher-volume use, especially when producing standard 4-inch tail shapes with realistic contouring. Material choices and cavity geometry support sharp detail without introducing excessive flash, making this mold attractive for anglers who want dependable, repeatable lures with solid action in water.
Adygil Jighead Mold Kit (73 Pieces)
The Adygil jighead kit offers a broad range of jighead configurations across 7g, 10g, 14g, and 18g with four cavities. This kit is designed to complement swimbait production by providing compatible heads for various lure designs. It supports a variety of eye sizes and head shapes, enabling makers to tailor buoyancy and casting performance to different fishing contexts. The kit approach is suitable for those who want modular options rather than a single fixed mold.
In practice, using the jighead mold kit with soft plastic swimbait bodies can yield versatile presentations, from shallow-water finesse tasks to deeper-water retrieves. The four-cavity layout helps optimize production throughput while still allowing experimentation with head weight and balance to achieve desired strike-triggering movement in water.
Buying Guide: Key Considerations for Open Pour Swimbait Molds
- Material and heat resistance: Look for CNC-machined, heat-tolerant molds that withstand long sessions without warping or releasing imperfections.
- Detail and finish: Assess vent design, seal quality, and cavity geometry to maximize fill and minimize bubbles or flash.
- Compatibility: Ensure the mold supports compatible soft plastics, release agents, and any additional hardware (eyes, jigheads) you plan to use.
- Maintenance: Favor molds with straightforward demolding and easy cleanup to sustain production rates and reduce downtime.
- Capacity and size: Choose cavity counts and bait lengths that align with your target fish species and fishing conditions.
- Cost versus durability: Higher-detail, CNC-machined molds tend to last longer and offer consistent returns on investment for frequent users.
- Modularity: For makers who want options, consider kits (like jighead sets) that expand your design capabilities without buying multiple separate molds.
- Safety and handling: Follow manufacturer guidelines for temperatures and handling to prevent burns and material degradation.
