Polyvinyl Chloride (PVC)

PVC is one of the most widely used materials in the production of 3D molded fishing lures due to its excellent balance of strength, flexibility, and moldability. It can be precisely cast into intricate, lifelike shapes—such as minnows, crawfish, or baitfish—enhancing visual appeal to predatory fish.

One of PVC’s key advantages is its ability to hold vibrant colors and internal reflective elements (like foil inserts), which increase visibility underwater. Additionally, soft-formulated PVC allows for natural undulating movement in the water, mimicking live prey. This realism makes PVC ideal for soft-body lures, jerkbaits, and swimbaits.

Thermoplastic Elastomer (TPE)

Thermoplastic Elastomer (TPE) is increasingly favored in lure manufacturing for its exceptional flexibility and durability across a wide range of temperatures. Unlike rigid plastics, TPE maintains its elasticity in both cold and warm water, ensuring consistent action and resilience during strikes.

TPE is especially effective in soft plastic lures such as grubs, worms, and creature baits, where a lifelike texture and subtle movement are critical. Its natural "give" when bitten enhances the chances of hooking fish. Furthermore, many TPE formulations are more environmentally friendly than traditional plastics, breaking down more readily and posing less long-term pollution risk.

Polyethylene (PE)

Polyethylene, particularly high-density polyethylene (HDPE), is valued for its toughness and rigidity, making it ideal for hard-bodied 3D lures. HDPE resists impact and abrasion, allowing lures to withstand repeated casting and contact with rocks or structure.

This material is easily injection-molded into complex geometries and can be colored throughout or painted for detailed finishes. Lures made from PE often produce a quieter, more subtle action in the water—perfect for clear conditions where fish are easily spooked. Their durability ensures long-term use across multiple fishing trips, offering excellent value for anglers.

Lead and Alternative Metals

Weight is essential for controlling a lure’s depth, casting distance, and swimming profile. Lead has traditionally been the metal of choice due to its high density, malleability, and cost-effectiveness. It is commonly embedded within the lure body or used in components like jig heads, internal weights, and lip ballast.

However, due to environmental concerns over lead toxicity, many manufacturers are now using eco-friendly alternatives such as tungsten, tin, steel, or bismuth. These metals offer similar performance with reduced ecological impact. Tungsten, for example, is even denser than lead, allowing for smaller, more sensitive lures with superior vibration transmission.

Silicone Rubber

Silicone rubber is renowned for its extreme flexibility, UV resistance, and ability to return to its original shape after deformation—making it perfect for high-performance soft lures. It performs exceptionally well in both saltwater and freshwater environments, resisting degradation from prolonged exposure to sunlight and moisture.

Silicone can be molded into highly detailed forms, such as tentacles, fins, or segmented bodies, providing unmatched realism. Its soft texture is attractive to fish, and its durability means it can survive multiple strikes without tearing. Common applications include soft jerkbaits, paddle-tail swimbaits, and imitation crustaceans.
