Introduction

Every angler knows the frustration of having the perfect honey hole but the wrong color or action on their lure. Maybe the fish are keyed into a specific shade of translucent purple that no tackle shop carries. Or perhaps you want a worm with a slightly softer texture for a better hook set. Learning how to make soft fishing lures gives you total control over your presentation. At BattlBox, we appreciate the self-reliance that comes with joining BattlBox and crafting your own gear. This guide covers everything from the chemistry of plastisol to pouring your first custom mold. By the end, you will understand how to create professional-quality soft plastics that catch more fish and save you money over time.

Quick Answer: Making soft fishing lures involves heating liquid plastisol to approximately 350°F until it becomes clear and syrupy, adding pigments and glitter, and pouring the mixture into a mold. You can purchase pre-made aluminum molds or create your own using plaster of Paris or silicone.

Why Make Your Own Soft Plastics?

Making your own lures is more than just a hobby. It is a way to gain a tactical advantage on the water. When you manufacture your own baits, you can adjust the scent, buoyancy, and salt content to match specific water conditions. Commercial lures are designed to sell to the widest possible audience. Your custom lures are designed to catch fish in your local river or lake, and the Fishing Collection is a solid place to keep that tackle box ready.

If you want another hands-on breakdown, How to Make Your Own Plastic Fishing Lures walks through the same DIY mindset from a different angle.

There is also a significant cost benefit. While the initial setup for equipment requires an investment, the cost per lure drops significantly once you start pouring in bulk. You can even melt down old, torn-back plastics to recycle them into brand-new lures. This sustainability ensures you always have a fresh supply of your favorite patterns without another trip to the store.

Essential Safety Gear and Workspace

Before you buy your first gallon of plastic, you must prioritize safety. You are working with liquid plastic heated to over 300°F. If this touches your skin, it sticks and continues to burn, similar to napalm. You are also dealing with chemical fumes that should not be inhaled, which is why the Medical & Safety collection is the right place to start.

Always work in a well-ventilated area. A garage with the door open or a dedicated outdoor shed is ideal. Never pour plastics in a kitchen or a space without a strong exhaust fan.

Necessary PPE (Personal Protective Equipment)

• Respirator: Use a Parcil Safety PD-101 Full-Face Respirator Gas Mask With OV & Particulate Filtration rated for organic vapors. Standard dust masks will not protect you from plastic fumes.
• Heat-Resistant Gloves: Leather work gloves are essential for handling hot glass measuring cups.
• Eye Protection: Safety glasses protect against accidental splashes or "burps" in the plastic.
• Long Sleeves and Pants: Cover your skin to prevent contact burns.

Important: Dedicate a microwave specifically for lure making. Do not use the same microwave you use for food. The chemicals released during the heating process can leave toxic residues on the interior surfaces.

The Supplies You Need to Start

To get started, you need a few core ingredients and tools. Most of these can be found in a specialized Emergency / Disaster Preparedness Collection or through tackle-crafting retailers. We often see gear enthusiasts start with basic kits before moving into more advanced custom pouring.

The Ingredients

1. Plastisol: This is the liquid plastic base. It usually looks like milk when cold. It comes in different Shore hardness levels, such as Soft, Medium, and Hard (Saltwater).
2. Colorant: These are highly concentrated liquid pigments designed specifically for plastisol.
3. Glitter: Only use high-heat polyester glitter. Craft store glitter will melt and ruin your bait.
4. Scent: Oil-based scents like garlic, crawfish, or coffee can be added to the hot plastic or applied as a soak later.
5. Worm Oil: This prevents the baits from sticking together in the bag and gives them a professional sheen.

The Tools

• Glass Measuring Cup: Use a high-quality, heat-resistant glass cup like Pyrex. Avoid plastic or cheap glass that may shatter.
• Metal Stirring Sticks: Use stainless steel spoons or butter knives. Avoid wood, as wood contains moisture that can cause the plastic to bubble and pop. A SOG PowerPint can also come in handy for small bench-side fixes.
• Infrared Thermometer: This is critical for monitoring the temperature of the plastic without touching it.

Understanding Lure Molds

The mold defines the shape and action of your lure. There are two primary types of pouring: open-pour and injection. Open-pour molds are flat on one side and filled from the top. Injection molds are two-piece units where you use a large syringe to force plastic into a cavity.

How to Make a DIY Plaster of Paris Mold

If you are on a budget, making your own mold from Plaster of Paris (POP) is the best way to start. It allows you to clone your favorite existing lures or even carved wooden prototypes.

For another beginner-friendly perspective, How to Start Making Fishing Lures: A Comprehensive Guide for Anglers is a good place to compare notes before you pour.

Step 1: Prepare the Casting Box. Find a small plastic container or build a box out of foam board. It should be about an inch larger than the lure you want to copy on all sides.

Step 2: Secure the Master Lure. Use a small amount of glue or double-sided tape to fix the "master" lure (the one you are copying) to the bottom of the container. Ensure it is flat and secure so it doesn't float when you pour the plaster.

Step 3: Mix and Pour the Plaster. Mix your POP according to the package directions. Pour it slowly over the lure. Tap the sides of the box repeatedly to vibrate out any air bubbles trapped against the lure's surface.

Step 4: Cure and De-mold. Let the plaster sit for at least 24 hours. Once hard, pop the plaster block out of the container and carefully remove the master lure.

Step 5: Dry and Seal. The mold must be bone-dry. You can bake it in an oven at 150°F for two hours to remove deep moisture. Once dry, seal the cavity with a high-heat epoxy or a mixture of white glue and water to create a smooth surface.

Key Takeaway: Moisture is the enemy of hot plastic. If your mold is not completely dry, the hot plastisol will turn that moisture into steam, causing the plastic to bubble or even erupt out of the mold.

The Pouring Process: Step-by-Step

Once your workspace is set and your mold is ready, it is time to pour. This process requires patience and attention to detail.

Step 1: Shake the Plastisol. The plastic resins often settle at the bottom of the container. Shake it vigorously for at least a minute to ensure a consistent mix.

Step 2: Heat the Liquid. Pour the desired amount of liquid into your glass cup. Heat it in the microwave in 30-second bursts. Stir between every burst. As it heats, it will turn from a milky white to a thick, gel-like state, and finally into a clear, runny liquid.

Step 3: Check the Temperature. Use your infrared thermometer. You want the plastic to reach 350°F. If you go too far above 380°F, the plastic will scorch, turn yellow, and smell terrible.

Step 4: Add Color and Glitter. Once the plastic is clear and at the right temperature, add your liquid pigment one drop at a time. Stir thoroughly. Add your glitter last to prevent it from settling.

Step 5: The Pour. Hold the cup close to the mold. Start at the "head" or the thickest part of the mold and pour in a thin, steady stream. For thin tails, pour slowly to allow the plastic to flow into the narrow channels.

Step 6: Let it Set. Wait about 5 to 10 minutes for the plastic to cool. Once the lure feels firm and is no longer tacky, gently pull it from the mold.

Step 7: The Water Bath. Drop the hot lures into a bucket of cold water. This "shocks" the plastic, helping it set its final shape and preventing the lures from warping while they are still warm.

Advanced Techniques for Better Lures

Once you master the basic pour, you can start experimenting with advanced designs. This is where you can truly differentiate your baits from anything found on a retail shelf.

How to Make Fishing Lures at Home covers a similar DIY process if you want another reference while you experiment.

Multi-Color Laminates

To create a "natural" look with a dark back and a light belly, you can perform a laminate pour. Pour the first color (usually the belly) into the bottom half of the mold. Wait about 30 to 60 seconds for it to develop a skin, then pour the second color on top. If you wait too long, the layers won't bond. If you pour too soon, the colors will bleed together.

Adding Salt and Weight

Adding fine-ground salt to your mix does two things: it adds flavor that makes fish hold on longer, and it adds weight. Salt-heavy baits, like the famous Stick Worms, sink faster and cast further. If you want a bait to float (like a topwater frog), avoid salt and use a "Hard" or "Floating" grade plastisol.

Using Scents Effectively

While you can add scent to the hot plastic, much of it can "cook off" due to the high heat. Many professionals prefer to bag their finished lures with a few drops of concentrated oil. This allows the plastic to absorb the scent over several days, making it much more potent when it hits the water.

Bottom line: Success in lure making comes from consistency. Keep a notebook to record how many drops of dye and how much glitter you use for specific recipes so you can replicate your best "secret" colors later.

Troubleshooting Common Issues

Even experienced makers run into problems. Here is how to fix the most common issues.

• Bubbles in the Plastic: This usually happens if you stir too vigorously or if there is moisture in your stirring tool or mold. Stir slowly and ensure everything is dry.
• The Lure is Too Soft: You may have used "Soft" plastisol for a large bait that needs more structure. Switch to "Medium" or "Hard."
• Dull Surface Finish: This happens with plaster molds. To get a high gloss, ensure your mold is sealed perfectly with epoxy, or switch to an aluminum mold.
• Colors Bleeding: Some pigments are "bleeders," meaning they will eventually migrate into other colors in the same bag. Look for "non-bleed" pigments if you plan on making multi-colored lures.

Myth: You can use any plastic, like old soda bottles, to make lures. Fact: Lures must be made from plastisol, which is specifically formulated to remain flexible. Melting down random household plastics is dangerous and will not produce a usable fishing lure.

Maintaining Your Gear

Your molds and tools will last for years if you treat them right. After a pouring session, wipe out your glass cups while they are still warm. The cooled plastic can be peeled out in one piece, which is very satisfying. Store your aluminum molds in a dry place to prevent any surface oxidation.

If you are using Plaster of Paris molds, keep them in a climate-controlled area. Extreme humidity can soften the plaster over time. Before every use, inspect your glass cups for any tiny cracks or "spiders," and keep an eye on the Flashlights collection if you want better visibility while you work. If you see a crack, throw the cup away immediately. A cup shattering in the microwave full of 350-degree plastic is a disaster you want to avoid.

Practicing the Craft

Don't expect your first pour to look like a factory-made lure. Like any skill we discuss at BattlBox, it takes practice. Start with simple shapes like a "senko" style stick bait or a basic grub. These are forgiving and very effective for bass and panfish.

If you want a fishing-specific next step, the Exotac xREEL Roundabout Kit keeps hooks, lures, and weights organized in a compact package.

As you get more comfortable with the temperatures and the "flow" of the plastic, move on to more complex shapes like swimbaits with paddle tails. The paddle tail is the hardest part to pour because the plastic must be hot enough to reach the very end of the thin tail section before it cools.

FAQ

What is the best temperature for pouring soft plastics?

The ideal temperature for most plastisols is 350°F. At this point, the plastic is fully "converted," meaning it has changed from a milky liquid to a clear, pourable state. Always use an infrared thermometer to ensure you don't exceed 380°F, which can cause the plastic to scorch and release toxic fumes.

Can I melt down old fishing lures to make new ones?

Yes, you can recycle old soft plastics by melting them down. Ensure they are clean and free of dirt or salt before melting. Keep in mind that mixing different brands or colors may result in a "muddy" brown or purple color, and the salt content might make the plastic smoke more during the reheating process. If you want more ready-made options, the Fishing Collection is a useful backup.

Is making your own lures cheaper than buying them?

In the long run, yes. While the initial cost of a microwave, molds, and plastisol can be high, the price per lure eventually drops to just a few cents. This is especially true if you pour high volumes of expensive baits like large swimbaits or specialized creature baits. If you want to compare the DIY route with more guidance, How to Make Handmade Fishing Lures: A Comprehensive Guide is a helpful companion.

Why are my soft plastic lures sticky after they cool?

Stickiness is usually caused by the plastic not reaching a high enough temperature to fully cure, or by an excess of certain oils in the mix. To fix this, ensure you hit 350°F during the heating process. You can also lightly coat finished lures in worm oil or unscented talcum powder to eliminate tackiness.
