Plastic Color Mixer
Fast, uniform pre-mixing for stable color and consistent additive dosing.
Nicety’s plastic color mixer is a compact vertical small-batch pre-blending machine designed to mix plastic pellets with masterbatch, pigments, or functional additives before injection molding, extrusion, or film production. It helps reduce color variation, improves feeding consistency, and minimizes scrap during frequent color changes.
- Stable color consistency for pellets + masterbatch / pigment blends
- Small-batch friendly for quick recipe switching and less waste
- Easy cleaning with stainless options and smooth inner surfaces
For more plastic mixer options, see our Plastic Mixer Types Overview for a complete guide.
What is a Plastic Color Mixer?
A plastic color mixer is a pre-mixing machine used to blend resin pellets with color masterbatch (or pigments/additives) so the downstream process receives a more uniform feed. Compared with adding masterbatch directly at the hopper, pre-mixing helps reduce color streaks, improves color repeatability, and stabilizes additive ratios—especially when you run short batches and change colors frequently.
For a broader comparison of mixer categories and use cases, refer to our all mixer types.

Our understanding of Color Mixer comes from decades of production experience
Typical Materials & Recipes:
This vertical pre-mixer is commonly used for:
Plastic pellets + masterbatch (e.g., PP/PE/ABS/PS pellets + color masterbatch)
Pellets + functional additives (anti-UV, slip agents, processing aids, etc.)
Regrind / recycled pellets + color correction
Pellets + small-ratio additives where stable feeding matters

How Do Plastic Mixer Machines Improve Color Stability and Additive Dispersion?
Why Pre-Mixing Improves Color Stability?
1) More uniform feeding = fewer color swings
When masterbatch is pre-mixed with pellets, the blend reaching the hopper is more consistent, helping reduce color drift caused by uneven dosing during feeding.
2) Reduced streaks and “spotting”
Pre-mixing can reduce visible streaks that happen when masterbatch or pigment is not distributed evenly before melting and screw mixing.
3) Faster color changes with less waste
Small-batch pre-mixing reduces the amount of off-color material during transitions and makes frequent recipe changes easier to manage.
4) Better control of small ratios
For low-percentage additives, a pre-mix step improves repeatability compared with direct hand-adding at the machine.

How the Vertical Plastic Color Mixer Works?
A typical workflow looks like this:
Load pellets + masterbatch/additives into the mixing chamber
Vertical mixing action blends materials evenly in a short cycle
Discharge the blended material to the hopper / feeding system
Run production with more stable input consistency
If your process requires large-batch pellet homogenizing or storage blending, consider a Vertical Silo Mixer instead.
For powder + additive formulations (or heavier mixing loads), consider a Horizontal Mixer.
Below is a common specification framework. (Final configuration depends on material, batch size, and dosing needs.)
Typical parameters
Batch capacity: small-batch (custom options available)
Mixing time: depends on material and ratio (short cycles for pellet + masterbatch pre-mix)
Motor power: configured by capacity and mixing load
Chamber material: SS304 standard; SS316 optional
Discharge: manual or assisted discharge options
| Model | Capacity/Volume | Mixing Motor Power | Dimension | Mixing Speed | Weight |
|---|---|---|---|---|---|
| NC - X50 | 50Kg | 1.5Kw | 2HP | 85(L)*85(W)*115(H)mm | 85 rpm | 130kg |
| NC - X100 | 100Kg | 3Kw | 4HP | 100(L)*100(W)*130(H)mm | 85 rpm | 180Kg |
| NC - X150 | 150Kg | 4Kw | 5.5Hp | 115(L)*115(W)*130(H)mm | 85 rpm | 270Kg |
| NC - X200 | 200Kg | 7.5Kw | 10HP | 125(L)*125(W)*140(H)mm | 85 rpm | 320Kg |

The FAQs About High Speed Mixer
In many factories, yes. A plastic color mixer is commonly used to pre-mix pellets with masterbatch (and sometimes additives) to stabilize feeding and improve color consistency.
It can significantly reduce streaks caused by uneven feeding. Final results also depend on screw design, melt conditions, and processing parameters.
Mixing time depends on pellet type, masterbatch ratio, and batch size. Pellet + masterbatch pre-mixing is usually a short cycle.
Yes, but pigment powder may require dust control (sealed lid/dust cover) and careful handling to keep the workspace clean.
A smooth chamber and quick-clean design reduces cross-contamination. If you change colors frequently, tell us your changeover frequency so we can optimize the structure.
Yes. Many users pre-mix functional additives (anti-UV, slip agents, processing aids, fillers at small ratios) for stable feeding.
Yes. We can provide interfaces for vacuum loaders and optional weighing/dosing solutions for consistent ratios.
For heavier mixing loads (powder + additives), consider a Horizontal Mixer:
For compounding with heating and fast dispersion, consider High Speed Mixer (Hot/Cold):
