Mixing Silicone Mold Compound
Making soft plastic fishing lure molds needs careful mixing of silicone mold compound. The right mix creates strong, flexible molds that last long.
This guide explains how to measure, mix, and avoid air bubbles in your silicone mold compound.
Measuring Ingredients
Use a clean scale or measuring cups to get exact amounts. Accurate measuring keeps the silicone strong and cures it properly.
Follow the silicone product instructions for the right ratio of base to catalyst. Too much or too little catalyst causes problems.
- Measure base silicone first
- Add catalyst carefully
- Check ratio on product label
- Use tools that are clean and dry
Mixing Techniques
Mix silicone slowly and steadily to blend the base and catalyst well. Stirring too fast can create bubbles.
Use a flat stir stick and scrape the sides and bottom of the container. This helps to mix all parts evenly.
- Mix for at least 2-3 minutes
- Stir in a figure-eight motion
- Scrape container edges often
- Avoid whipping air into the mix
Avoiding Air Bubbles
Air bubbles can weaken your mold. To prevent bubbles, pour silicone slowly and tap the container gently.
You can also let the mixed silicone sit for a few minutes. This allows bubbles to rise and pop before you pour.
- Pour silicone slowly and steadily
- Tap or shake container lightly
- Let mixture rest for 5 minutes
- Use a vacuum chamber if available

Mold Making Process
Making soft plastic fishing lure molds requires careful steps. The process uses silicone to create a flexible mold.
This guide explains how to set up the mold container, pour silicone, and cure the mold properly.
Setting Up The Mold Container
Choose a container that fits your lure prototype well. It should be slightly bigger than the lure on all sides.
Seal the bottom and sides to prevent silicone leaks. Use clay or hot glue to close any gaps.
- Use a plastic or glass container
- Make sure the container is clean and dry
- Seal corners with clay or tape
- Leave extra space for silicone around the lure
Pouring Silicone Over Prototype
Mix silicone according to the package instructions. Pour slowly to avoid air bubbles.
Start pouring at one corner and let silicone flow over the lure. This helps reduce trapped air.
- Wear gloves for protection
- Mix silicone thoroughly but gently
- Pour silicone slowly over the prototype
- Tap container lightly to release bubbles
Curing Time And Conditions
Let the silicone cure in a dust-free area. The curing time depends on the silicone type used.
Maintain a stable room temperature for the best results. Avoid moving the mold during curing.
- Typical curing time: 6 to 24 hours
- Ideal temperature: 70 to 80°F (21 to 27°C)
- Keep mold undisturbed during curing
- Check manufacturer instructions for details
Demolding And Finishing
After making your soft plastic fishing lure molds, you need to remove them carefully. This step protects your mold from damage. Finishing the mold ensures your lures come out perfect every time.
Good demolding and finishing improve the mold’s life. They also make your fishing lures look professional and work well in the water.
Removing The Mold Carefully
Wait until the silicone mold is fully set before removing it. Gently pull the mold away from the lure shape. Avoid using sharp tools that can tear the silicone.
Use slow and even pressure. Stretch the silicone if needed to release the shape inside. Work your way around the mold to keep it intact.
Trimming Excess Silicone
After removing the mold, you may see extra silicone edges. These are called flash. Use a sharp craft knife or scissors to trim them off carefully.
Trim close to the mold shape but do not cut into the detail areas. A clean edge helps the plastic flow better during casting.
- Use a new, sharp blade for clean cuts
- Trim small bits at a time
- Check edges under good light
Inspecting Mold Quality
Check your mold for any tears, bubbles, or imperfections. Small bubbles can create weak spots in your lures. Tears can cause leaks during casting.
Look inside the mold for smooth surfaces. The better the mold quality, the better your soft plastic lures will turn out.
- Run your fingers gently over mold edges
- Look for holes or thin spots
- Fix small issues with extra silicone if needed
