Plastic Injection Moulding: Best Guide to Know Custom Colors in Moulding

Color proves to be an exceptionally powerful tool in the realm of plastic injection moulding. Because, it goes beyond mere aesthetics, playing a crucial role in communicating brand identity, ensuring safety, and enhancing functionality. For those engaged in crafting custom plastic injection moulding parts, this blog aims to elucidate the preparation of colors for molding, and guiding you to answer the pivotal question: What color is essential for your plastic moulding parts?

Essentially, Color Preparation For Plastic Injection Moulding Involves Four Distinct Methods

Custom Plastic Injection Molding

When delving into custom colors in plastic injection moulding, four primary methods are utilized to attain the desired hues:

  1. Masterbatch Colorants:
    • How It Works: Concentrated pellets or granules containing pigments dispersed in a carrier resin are mixed with the base resin during the plastic injection moulding process.
    • Advantages: This method ensures excellent color consistency, easy handling, and minimal impact on material properties.
    • Considerations: Achieving accurate color matching may necessitate close collaboration with your material supplier or a colorant provider.
  2. Precolored Resins:
    • How It Works: Some resin manufacturers provide precolored resin pellets, eliminating the need for additional colorants in custom plastic injection moluding. These resins, available in various shades, can be directly used in the injection moulding process.
    • Advantages: Precolored resins simplify the coloration process and deliver consistent results.
    • Considerations: Limited color options and potential material restrictions may apply.
  3. Dry Pigments:
    • How It Works: Powders or granules of dry pigments are mixed directly with the base resin during processing, offering flexibility in achieving custom colors in plastic injection moulding.
    • Advantages: Dry pigments provide a broad range of color options and can be blended to create unique hues.
    • Considerations: Uniform color distribution relies on proper mixing and dispersion.
  4. Liquid Colorants:
    • How It Works: Liquid colorants, in liquid form, are mixed with the base resin and are often utilized in applications where precision in color is crucial.
    • Advantages: Liquid colorants offer excellent color accuracy and uniformity.
    • Considerations: Precise metering and mixing may require specialized equipment.

What Color Do You Need For Your Custom Plastic Injection Moulding?

In determining the color you need, blend creativity and practicality. Here are some factors to consider for your custom plastic injection molding:

  • Brand Identity: Consider whether the color of custom plastic injection molding aligns with your brand’s identity, and evaluate, how maintaining consistency in color across your product line can significantly enhance brand recognition.
  • Aesthetics: Contemplate the visual appeal of the color and assess whether it resonates with your target audience.
  • Functionality: In some industries, color coding is crucial for safety and functionality. Ensure that your plastic injection molding serves a practical purpose by choosing a color that aligns with the required functionality if necessary.
  • Customization: Explore custom color options through color-matching services if you are looking for a unique shade that sets your product apart.
  • Material Compatibility: Consider whether the chosen color is compatible with the material you intend to use. Because some plastics may interact differently with certain colorants.
