Premixing of color masterbatch extruder:
In the premix process, all masterbatch raw material components are first mixed in a mixer. Then, normally via a volumetric feeder, this mixture is fed into the twin screw extruder where it is processed.
Also you can choose loss-in-weight feeder for more precise and gentle feeding.
1.Water strand pelletizing line for color masterbatch extruder
It is the most commonly used and economic method for color masterbatch making.
Application:
Incorporation of Fillers: Caco3, Talc, TiO2, carbon black,filled PE, PP, or EVA, etc.
High Concentration Color Masterbatches: PE, ABS, PS, EVA, PP,etc. with high concentration of pigments and other processing aids.
Masterbatches with Flame-retardants: PE, ABS, PS, EVA, PET, PP, etc. with flame retardants and other additives.
2. Water Ring pelletizing line for color masterbatch extruder
Water ring granulation can be applied to formulations with large differences in melt characteristics. On the other hand, the water ring cutting have a shorter residence time in the water, and the moisture content after the dehyddrator and the vibrating screen is less than 0.1%, and no additional drying is required.
Application:
PE, EVA etc. Filled with CACO3,talc,TIO2,carbon black etc.
Color concentrations of PE,ABS, PS,EVA,etc;
Flame retardant master batches of ABS,PS,EVA,etc;
Master batches with PE,PP,PS,etc carriers for degradation applications.
3. Underwater pelletizing line for color masterbatch extruder:
For more output: the strands go into the pelletizer automatically by the water flow, even the strands break during changing the filter. So there will be almost no waste during the manufacturing process.
Underwater pelletizing system also used to handle micro pellets making with a size of ≤ 1mm.

Color Masterbatch Production & Twin-Screw Extrusion: Frequently Asked Questions
Q1: What exactly is a "color masterbatch"?
A: A color masterbatch is a highly concentrated blend of pigments or dyes that have been perfectly dispersed into a "carrier resin" (such as PP, PE, PS, ABS, or PET).
Instead of handling messy raw pigment powders, plastic manufacturers simply add a small percentage of these masterbatch pellets to their raw plastic during production. It is a much cleaner, more precise, and highly efficient way to color plastics for industries like automotive, packaging, and electronics.
Q2: Why are twin-screw extruders essential for producing masterbatch?
A: The quality of a masterbatch depends entirely on how well the pigment is dispersed. Standard single-screw extruders simply cannot provide the necessary mixing power.
Co-rotating twin-screw extruders are the industry standard because they offer:
Intense Mixing: Powerful dispersive and distributive mixing capabilities.
Precise Control: Strict control over shear forces and residence time inside the barrel.
Stability: Highly stable temperature and pressure profiles, alongside accurate feeding of lightweight powder pigments.
Q3: How does a twin-screw extruder turn raw pigment into masterbatch pellets?
A: The production process happens in four highly controlled stages inside the machine:
1.Accurate Feeding: Pigments, the carrier resin, and any additives are precisely fed into the extruder using gravimetric or volumetric feeders.
2.High-Shear Dispersion: Specially designed screw elements apply targeted shear and kneading forces. This smashes pigment agglomerates (clumps) and distributes the color uniformly at a microscopic level.
3.Filtration: The fully mixed melt passes through a melt filter or screen changer to remove any impurities.
4.Pelletizing: The molten masterbatch is pushed through a die and cut into uniform granules, ready for easy storage and downstream dosing.
Q4: How do masterbatch pellets work in the final plastic product?
A: When a manufacturer is ready to make the final product (like a plastic bottle or car dashboard), they mix the masterbatch pellets with their base, uncolored resin. During injection molding or final extrusion, the masterbatch melts and the concentrated color disperses evenly throughout the final polymer. Manufacturers can easily adjust the color shade or intensity simply by changing the masterbatch dosing rate.
Q5: What are the main benefits of producing masterbatch with a twin-screw system?
A: For companies producing masterbatch, utilizing a high-quality twin-screw extrusion line provides several massive advantages:
Zero Color Variation: Uniform dispersion guarantees excellent color consistency from batch to batch, without streaks.
Reduced Pigment Costs: Because the twin-screw system breaks down and distributes the pigment so efficiently, you need less raw pigment to achieve the desired color strength.
Formulation Freedom: Operating your own compounding line allows you to develop, adjust, and protect your own proprietary color formulations in-house.
Reliable Operations: Controlled processing parameters ensure high repeatability and stable, scalable production.
The Machines to Produce Color Masterbatch provide precise mixing, dispersing, and pelletizing of pigments and additives into polymer carriers, ensuring vibrant color, consistent quality, and high production efficiency.
