Key Features
- Match color from real samples, Pantone/RAL codes, or standard color cards.
- Carrier and dispersion can be matched to PP, PE, PET, ABS, PS and similar resin systems.
- Made for parts where the same shade needs to stay consistent from batch to batch.
- Pearlescent, fluorescent, brightening, UV-resistant and other effects can be added when needed.
- After sample approval, the formula can move into regular batch production with color records kept for repeat orders.
Applications
- Injection molding part coloring
- Blow molded bottle and plastic container coloring
- Plastic packaging cap and housing coloring
- Daily-use product, toy, and household plastic part coloring
- Extrusion sheet, pipe, or profile coloring
- Colored plastic product projects
OEM / Customization Capabilities
- Color customization: Color matching is supported by Pantone, RAL, color plates, sample parts, or customer color samples.
- Resin matching: The formula can be adjusted for PP, PE, PET, ABS, PS, EVA, PLA, and other resins.
- Dosing ratio adjustment: Masterbatch concentration can be adjusted according to transparency, hiding power, and cost requirements.
- Functional additive compounding: UV resistance, anti-static, brightening, pearlescent, fluorescent, and other effects can be added as required.
- Sample confirmation: Color plates, injection molded samples, or customer-resin test samples can be provided.
- Batch standard retention: Color standards can be retained according to the approved sample to reduce color variation in later batches.

Frequently Asked Questions
1. What information is needed for color matching?
-
It is recommended to provide the target color sample, Pantone / RAL color code, resin type, processing method, product thickness, and final application.
2. How should the dosing ratio be confirmed?
-
The dosing ratio should be confirmed based on color depth, hiding power, base resin color, product thickness, and production testing.
3. Is it suitable for transparent or translucent products?
-
Yes. The formula can be adjusted for transparent, light-color, and translucent products according to resin transparency and product thickness.
4. Is dosing equipment required?
-
A liquid masterbatch metering pump or controller is recommended to reduce dosing fluctuation and manual weighing errors.
5. How is batch-to-batch color difference controlled?
-
Custom colors are matched against the approved sample, standard color plate, or customer sample. Sample results should be confirmed before batch production.
