What do I need to get started with soft plastic mold making?

What's the best plastic type for a Do-It mold?

The best plastic type for a Do-It soft plastic mold is generally a plastisol designed specifically for soft plastic lure making. These plastisols are formulated to be heat-resistant, durable, and flexible after curing, allowing for repeated use without damaging the mold and producing lures with lifelike action.

The key considerations when selecting a plastisol are its viscosity, heat tolerance, and desired hardness. Do-It molds are typically made of aluminum, which can withstand moderate heat, but excessive temperatures can warp or damage them over time. Therefore, it's crucial to use a plastisol that cures within the temperature range recommended by both the plastisol manufacturer and Do-It. Lower viscosity plastisols tend to flow more easily into intricate mold details, resulting in better lure definition. Furthermore, the plastisol's hardness, often measured in Shore A durometer, will determine the lure's flexibility and action in the water. Different plastisols are available to achieve different properties. For example, you might use a standard plastisol for general-purpose lures, a super-soft plastisol for lures requiring maximum action, or a hard plastisol for lures intended to be more durable and resistant to tearing. Adding plasticizers can further modify the softness, while hardeners can increase durability. Always follow the manufacturer's instructions for heating and curing, and start with small batches to dial in the perfect settings for your specific mold and desired lure characteristics.

How do I prevent air bubbles when injecting plastic into a Do-It mold?

Preventing air bubbles when injecting plastic into a Do-It mold requires careful attention to technique and material preparation. The key is to ensure a smooth, continuous flow of plastic, avoiding any sudden stops or starts that can trap air. This often involves pre-heating the mold, using the correct injection pressure, and employing a steady hand during the injection process, while also paying close attention to the consistency of your plastic.

Achieving bubble-free soft plastics starts with properly preparing your plastisol. Make sure your plastic is thoroughly mixed, free of any solid chunks, and heated to the correct temperature recommended for your specific plastisol and mold type. Overheating can cause the plastic to become too thin and prone to air entrapment, while underheating can lead to incomplete mold filling and increased viscosity, making it harder to force air out. Experiment with small batches to dial in the ideal temperature for consistent results. Beyond the plastisol itself, the injection technique significantly impacts bubble formation. When injecting, maintain a constant, even pressure, avoiding rapid bursts or pauses. Start injecting slowly to allow the plastic to flow into the mold cavities, gradually increasing pressure as needed to fully fill the mold. Tilting the mold slightly during injection can also help air escape from the highest points. If you're consistently struggling with bubbles in a specific area of the mold, consider slightly modifying the injection port or adding a small vent to allow air to escape. Finally, ensure your mold is clean and pre-heated to facilitate even flow. A cold mold can cause the plastisol to cool too quickly, hindering proper filling and increasing the likelihood of trapped air. Pre-heating doesn't need to be excessive; a few minutes with a heat gun or on a hot plate will suffice. Regularly cleaning the mold with a mold release spray will further help to ensure a smooth, bubble-free injection process.

What temperature should I heat the plastic to for a Do-It soft plastic mold?

The ideal temperature for heating plastisol when using Do-It soft plastic molds typically ranges from 325°F to 375°F (163°C to 190°C). However, this range is a guideline, and the precise temperature depends on the specific plastisol brand, mold design, and desired softness of the finished bait.

It's crucial to consult the plastisol manufacturer's instructions for their recommended heating temperature. Some plastisols may require a slightly higher or lower temperature for optimal flow and to prevent burning. Overheating can cause the plastic to scorch, become brittle, and release harmful fumes, while underheating can lead to incomplete fills and weak baits. When in doubt, it's best to start at the lower end of the range and gradually increase the temperature until you achieve consistent, complete mold fills.

Also consider the mold itself. Intricate molds with small details may require a slightly hotter plastisol to ensure it flows into all the crevices. Conversely, larger, simpler molds might work well with a lower temperature. Experimentation is key. Start with a small batch of plastisol and adjust the temperature in small increments until you find the sweet spot for your specific setup. Keeping a record of the temperatures that work best for each mold and plastisol combination will save you time and materials in the long run.

How do I properly clean and maintain my Do-It soft plastic molds?

Proper cleaning and maintenance of your Do-It soft plastic molds involves gently removing excess plastic after each use, thoroughly cleaning them periodically with warm, soapy water and a soft brush, and storing them in a clean, dry environment, preferably with mold release applied, to prevent damage and extend their lifespan.

After each molding session, allow the mold to cool down slightly but while the plastic is still somewhat pliable, carefully remove any excess plastic clinging to the mold's surface or in the sprue channels. A wooden or plastic tool is ideal for this to avoid scratching the mold. Avoid using metal tools for this purpose. Regularly clean your molds with warm water and a mild dish soap. Use a soft brush, like a toothbrush or a small parts cleaning brush, to gently scrub away any accumulated plastic residue, especially in intricate details. Rinse thoroughly and allow the mold to air dry completely before storing. Proper storage is crucial for maintaining the integrity of your Do-It molds. Store them in a clean, dry location away from direct sunlight and extreme temperatures. A plastic storage container or a dedicated drawer is ideal. Consider applying a mold release spray before storing the molds to provide a protective barrier against oxidation and sticking. This will also make it easier to remove baits during your next molding session. Regularly inspecting your molds for any signs of damage, such as cracks or warping, is a good habit. Addressing these issues promptly can prevent further deterioration and prolong the life of your valuable molds.

What's the best way to add color and scent to my soft plastics using a Do-It mold?

The best way to add color and scent to your soft plastics when using a Do-It mold is to incorporate them directly into the molten plastic before pouring. This ensures even distribution and consistent results throughout the finished bait.

First, you'll want to select high-quality plastic colorants and scents specifically designed for soft plastic baits. These are typically available in liquid or powder form. Liquid colorants are generally easier to work with, as they readily mix into the hot plastic. Powdered colorants require more thorough stirring to prevent clumping. Add the colorant drop by drop (for liquids) or a small amount at a time (for powders) until you achieve your desired shade. As for scent, consider using oil-based scents, as they bind well with the plastic and provide a longer-lasting aroma compared to water-based alternatives. Common scent options include anise, garlic, crawfish, and shad. The key to success is proper mixing. After adding the color and scent, thoroughly stir the molten plastic for at least a minute to ensure even dispersion. Don't over stir and whip air into the plastic. Consider the volume of the Do-It mold so that you can estimate the color and scent to be added. Always test a small batch first to dial in your perfect color and scent combination before committing to a larger pour. Remember to always use caution when working with hot plastic.

Can I modify a Do-It soft plastic mold to create a custom bait design?

Yes, you can absolutely modify a Do-It soft plastic mold to create a custom bait design. Many anglers and bait makers modify existing molds to achieve unique profiles, actions, and appearances not found in commercially available options. This allows for personalized baits tailored to specific fishing conditions or preferences.

Modifying a Do-It mold generally involves physically altering the aluminum mold cavities. Common techniques include using tools like Dremel rotary tools, files, and sandpaper to reshape the existing cavity. You can remove material to thin profiles, add texture, or change the shape of the bait's body, tail, or appendages. It's crucial to proceed carefully and incrementally, as removing too much material is difficult to reverse. Consider practicing on scrap aluminum or test molds before committing to major changes on your primary mold.

Before you start modifying your mold, it’s wise to consider the following:

Remember safety glasses and proper ventilation when working with metal tools. With patience and practice, modifying Do-It molds opens a world of possibilities for creating truly custom soft plastic baits.
