Soft Plastics Mold: Zoom Salty Super Fluke, Two Cavities
The Soft Plastics Mold is built for injection-based lure making with a standard 5/8″ nozzle compatibility, allowing many injectors to work smoothly. It uses engineered stone material—stone powder blended with polymers—to create a durable, low-porosity mold that preserves fine details. An integrated smart air vent system helps release trapped air, ensuring the soft plastic fills every contour of the mold for accurate ribbing, fins, and tail shapes. This setup is suitable for bass-focused worm designs that require consistent action and lifelike texture.
Smedioks Premium Soft Plastic Mold Lure Making Injection Molds
The Smedioks mold enables professional-grade lures at home with three cavities designed for 5″ Yama Senko-style worms. Its design prioritizes customization, allowing color and scent choices to tailor baits to different water conditions and bass behavior. The mold emphasizes cost efficiency for anglers who produce multiple lures across seasons, providing a scalable option for consistent bulk production without compromising detail or action.
Soft Plastics Mold: Crappie, 2 Inches, 10 Cavities
This Crappie-focused mold uses 2-inch lures with ten cavities, enabling rapid production of compact worm-like baits. The 5/8″ injection size matches most standard injectors, and the engineered stone composition supports repeated pours with stable results. The vents system helps air escape so each cavity fills cleanly, preserving small ripples and tail features essential for fin- and tail-driven bass lures. Ideal for creating small-worm profiles for finesse presentations in tight cover.
Soft Plastics Mold: Roboworm Straight Tail Worms, 4.5″, Three Cavities
Roboworm-inspired straight-tail worm designs in a three-cavity mold deliver stable action and detailed textures. The same injection sizing and engineered stone material are emphasized, promoting consistent fill and easy demolding. The air venting system reduces air pockets, helping plastics fill all tail and body contours. This mold is well-suited for anglers targeting bass with straight-tail worm presentations that track with subtle in-water movement and predictable hooksets.
Fusion X Kit: Bass Essentials Starter Kit
The Fusion X Bass Essentials Starter Kit comes with eight premium silicone hand pour molds and seven colors of plastic, offering a turnkey solution for beginners and seasoned makers. The kit emphasizes a “heat and pour” workflow, eliminating the need for measuring or mixing. This streamlined approach is ideal for quickly producing a variety of flexible worm designs that can mimic natural forage—benefiting bass anglers who want to experiment with different colorways and scent options to optimize bite chances.
Buying Guide: Key Purchase Considerations
- Size and cavities: Choose molds with the right lure size and a cavity count that fits your production pace. More cavities mean faster output but require larger storage space.
- Material and durability: Engineered stone or synthetic stone blends offer stability and repeatable results. Look for low-porosity materials to preserve details after many pours.
- Injection compatibility: Ensure the mold matches your injector nozzle size (commonly 5/8″). This affects fill quality and mold life.
- Vent systems: Effective air vents reduce air pockets and improve the fidelity of tail shapes and texture.
- Detail fidelity: CNC-machined or precisely molded designs tend to yield more realistic swimming action, which can influence bite rates.
- Cost vs. value: Kits with multiple molds and color options may save money over time, especially for anglers who pour frequently.
- Ease of use: Starter kits with straightforward pouring steps are ideal for beginners, while more advanced molds suit experienced pourers seeking finer control over color and scent.
- Maintenance: Look for molds that are easy to clean and resistant to warping after repeated heating and cooling cycles.
- Compatibility with soft plastic formulations: Confirm that the molds are designed for common soft plastics and avoid molds that are only suitable for particular polymer blends.
- Environment and safety: Work in a well-ventilated area and follow manufacturer guidelines for heat and handling of hot plastics and additives.
