Selecting the Right Materials for DIY Fishing Lure Molds

The first step in your lure-making adventure is choosing the right materials. A successful lure mold hinges on the quality of the materials used, particularly the silicone rubber.

Silicone Rubber

Silicone rubber is the gold standard for creating fishing lure molds due to its resilience, flexibility, and ability to capture fine details. When shopping for silicone, consider the following:

• Type: Look for "tin cure" silicone rather than "platinum cure" options. Tin cure silicone is generally more affordable and easier to find.
• Quality: Avoid the lowest quality options, as they may have manufacturing defects that can affect your molds.
• Color: Clear silicone is versatile, but colored options can be useful for creating opaque lures.

Mold Frames

You will need a mold frame to contain the liquid silicone as it sets. Wooden craft frames from art stores work perfectly for this purpose. Ensure that the frame has one open side to facilitate easy pouring and removal of the mold.

Master Model Materials

The master model is the 3D form around which your silicone cures. You can create this model from various materials:

• Wood: Easily carved into desired shapes.
• Modeling Clay: Offers flexibility in design and is excellent for adding intricate details.
• 3D Printed Models: If you have access to a 3D printer, this can yield highly precise models.

Release Agents

Using a release agent will help prevent the silicone from sticking to your master model. Common options include petroleum jelly or specialized silicone mold release sprays.

Preparing Masters for Fishing Lure Molds

Creating the master model is a crucial step in the molding process. A well-prepared master ensures that your final lures will have the desired shape and detail.

Designing the Master

If you are sculpting from scratch, consider the specific lure design you want to create. You can start by sketching your design or modifying an existing lure. Remember to:

• Focus on Details: Add intricate features like scales, fins, and eyes to your master model to replicate the look of real bait.
• Seal the Surface: Once your master is complete, seal it with a clear acrylic spray. This prevents the silicone from sticking and ensures a smooth finish.

Positioning the Master in the Mold Frame

To prepare the mold frame, do the following:

1. Angle the Frame: Prop up one end of the frame slightly to allow air bubbles to escape during the pouring process.
2. Apply Release Agent: Coat the interior of the frame with a thin layer of petroleum jelly.
3. Secure the Master: Use small strips of modeling clay to hold the master securely in place, ensuring it is positioned about 1/4 inch from the frame's bottom and sides.

By taking the time to properly prepare your master model, you set the stage for a successful molding experience.

Setting Up the Mold Frame

Setting up your mold frame correctly is essential for achieving the best results. Here’s how to do it step-by-step:

Step 1: Prepare the Frame

Start with a clean, dry mold frame. Ensure there are no gaps or openings that could allow silicone to leak. If necessary, line the frame with a thin layer of modeling clay to create a tight seal.

Step 2: Position the Master Model

Place the prepared master model in the center of the mold frame. Ensure that it is stable and does not tilt. Use additional modeling clay as needed to keep it firmly in place.

Step 3: Check Alignment

Before pouring the silicone, take a moment to check the alignment of the master model. It should be positioned directly upwards, which ensures symmetrical molds that produce consistent lures.

Mixing and Pouring the Silicone Rubber

Once your mold frame is set up, it’s time to mix the silicone rubber. This is a critical step that requires careful attention to detail.

Step 1: Follow Manufacturer Instructions

Always read and follow the manufacturer's instructions for the silicone rubber you are using. Mix ratios can vary, so it’s crucial to get this right.

Step 2: Mixing the Silicone

• Combine Components: In a separate mixing container, combine the two components of the silicone rubber.
• Mix Thoroughly: Stir the mixture for 2-3 minutes to ensure complete incorporation. Pay attention to any bubbles that form during this process.

Step 3: Pouring the Silicone

• Pour Gradually: Carefully pour the silicone over the master model. Start from one side of the frame and allow the silicone to flow over the master to minimize air bubbles.
• Burst Bubbles: Use a toothpick to pop any bubbles that rise to the surface while pouring.
• Overfill: Aim to pour about 1/2 inch above the highest point of the master model to account for shrinkage as the silicone cures.

Step 4: Curing Time

Allow the silicone to cure undisturbed for 8-12 hours, or as directed by the manufacturer. Once cured, you should be able to peel away the excess silicone from the outer frame easily.

Removing Excess Silicone and Releasing the Mold

After the silicone has fully cured, it’s time to remove your newly created mold.

Step 1: Disassemble the Frame

Carefully take apart the mold frame, noting any resistance. If necessary, use a hobby knife to cut away any areas where the silicone has bonded with the frame.

Step 2: Free the Master Model

Gently pry or cut the master model free from the silicone mold. Be cautious not to damage the mold in the process.

Step 3: Inspect for Quality

Check the mold for any imperfections. A well-made mold will have a smooth cavity that accurately reflects the detail of the master model.

Preparing Soft Plastic for Pouring Lure Bodies

With your mold ready, it’s time to prepare the soft plastic for pouring. This step is all about precision and timing.

Step 1: Choose Your Plastic

For beginners, purchasing pre-colored soft plastic worms or baits to melt down can simplify the process. This eliminates the need for adding powder pigments.

Step 2: Melting the Plastic

• Use a Double Boiler: Gently heat the plastic using a double boiler or a dedicated melting pot.
• Monitor Temperature: Keep the temperature consistent to avoid burning the plastic. The ideal melting temperature is typically around 350°F (175°C).

Step 3: Pouring the Plastic

• Pour Slowly: Carefully pour the melted plastic into the mold cavity, taking care to avoid creating air pockets.
• Overfill Slightly: Pour a little more than necessary to account for any shrinkage as it cools.

Step 4: Allow to Cool

Let the poured plastic cool completely before attempting to remove it from the mold. This may take several minutes, depending on the thickness of the lure.

Removing and Trimming Poured Lure Bodies

Now that your lure bodies are cooled and solidified, it’s time to remove them from the mold and make any necessary adjustments.

Step 1: Carefully Remove the Lure

Gently pull the lure from the mold. If it is stuck, you may need to apply a light release agent to the mold’s interior before your next pour.

Step 2: Trimming Excess Plastic

Using sharp scissors, trim away any flashing—this is the excess plastic that can form along the seam lines of the mold. Keep the lure attached to the sprue to maintain its upright position.

Step 3: Add Hardware and Finishing Touches

Most anglers choose to enhance their lures with hooks, rings, or other hardware. Be sure to:

• Insert Hook Hangers: Position them where they’ll provide the best balance and action in the water.
• Secure with Super Glue: This ensures that all components stay firmly in place.
• Customize Appearance: Paint, add eyes, or apply a protective epoxy finish for added durability.

Troubleshooting Common Lure Molding Problems

Every craft has its challenges, and lure molding is no exception. Below are some common issues and their solutions:

Issue 1: Bubbles in Cured Silicone

Solution: Ensure the mold frame is at a slight angle when pouring, and burst any bubbles immediately after pouring.

Issue 2: Mold Sticks to Master

Solution: Increase the amount of release agent used on the master model. A thin layer of PVA release agent can also help.

Issue 3: Flash Residue on Bodies

Solution: Ensure that the mold frame fits tightly and pour at the correct temperature to prevent leaks.

Issue 4: Lures Stick in Mold

Solution: Lightly spray the interior of the mold with a release agent before pouring the plastic.

Issue 5: Plastic Not Flowing Smoothly

Solution: Check that the plastic is fully melted and hot enough before pouring.

Maintaining and Caring for Your Fishing Lure Molds

Proper care for your molds can significantly extend their lifespan and performance. Here are some essential tips:

Storage

• Keep Away from Sunlight: Store molds in a cool, dry place, away from heat and humidity.
• Avoid Degradation: Never leave unfinished lures sitting in molds, as plasticizer oils can degrade silicone over time.

Regular Maintenance

• Lightly Coat with Oil: Apply a light coat of vegetable oil to the interior of your molds to prevent sticking.
• Inspect for Damage: Periodically check your molds for wear and tear, replacing them as necessary.
