MAS-CCOLOR SORTING SERIES

Precision Flake
Color Sortingfor PET and Rigid Plastics

Advanced optical detection and high-speed ejection deliver exceptional color separation for PET and rigid plastic flakes. Purify clear, light-blue, green, and mixed-color streams with outstanding accuracy and stable performance.

01

Feed

Even flake delivery ensures consistent sorting.

02

Detect

Optical detection identifies color and material.

03

Accept / Reject

High-speed ejection delivers clean accepts and accurate rejects.

Why MAS-C

A color sorter built to make recovered plastic worth more.

The Maximum Sorting (MAS) color platform is engineered for flake and rigid-fragment streams where visible color and appearance decide product value.

Advanced color sorting

Precise separation driven by subtle color and shade variation across flakes and rigid fragments.

Cost-effective

Low maintenance keeps the total operating cost down across the machine's working life.

Real-time performance insight

On-board data analytics support process optimization and faster line decisions.

Streamlined operation

A clear, user-friendly interface shortens operator training time.

Energy savings

An energy-efficient design lowers power consumption per tonne sorted.

Compact design

A space-efficient footprint integrates into existing recycling lines.

Main applications

Two color-sorting jobs, one platform.

MAS-C is positioned by the visible sorting target rather than a vague plastic category, so the recipe stays concrete.

Application 01

General color sorting

Sort single- and double-sided colored plastic flakes, detect and remove opaque and black flakes from multicolored material, and pull black material out of mixtures such as PC alloy and PC / PP / PS / ABS.

Application 02

Color sorting in PP / PE

Separate red and yellow, blue and green, black, multicolored, transparent and white flakes from PP and PE material to recover clean, single-color fractions.

MAS-C Pro

An optional Pro build for the hardest color targets.

The Pro version inherits the MAS-C color-sorting performance and excels at extremely light-colored plastic flakes. It also purifies single-color streams and slight color differences in ABS / PP / PE, giving the flexibility to meet demanding quality targets.

Flake color stream

Mixed color flakes, accepted color range and off-color rejects.

MAS-C is framed around visible color and appearance sorting for prepared flakes or rigid fragments, not whole bottles.

Feed

Color boundaries depend on visible contrast, flake size, moisture, lighting, presentation and the selected recipe.

Raw materials

Color classes MAS-C is built to recover.

Switch between material families and click any class to see exactly what enters the machine and what comes out — feed, accepted product, recovered color fractions and reject classes.

Typical color fractions recovered from prepared PET flake streams.

Incoming feed

Mixed feed

Clear PET dominates the incoming stream, mixed with blue, green, amber, pink and slightly yellowed pieces. This is the raw flake curtain MAS-C reads before any decision is made.

Accepted and reject classes are always confirmed on your representative samples before a configuration is quoted.

The platform

A dedicated color-sorting platform, not a generic line.

Stable feeding and presentation, controlled visible-light imaging and precisely timed ejection are tuned around prepared flakes so color decisions stay repeatable from the first pass.

How it works

From color sample to reject timing.

MAS-C should be explained as controlled visible inspection and recipe-led ejection for prepared flakes.

  1. 01
    Customer-prepared

    Feed & stabilize

    Prepared flakes are metered by a vibratory feeder and spread into a thin, even curtain so every piece is presented to the cameras the same way. Stable presentation is what makes the color decision repeatable from the first pass.

  2. 02
    Controlled lighting

    Illuminate & image

    Calibrated full-spectrum LED lighting floods the inspection zone while high-resolution cameras capture each flake's color, brightness and transparency — read from both sides so a flake cannot hide its off-color face.

  3. 03
    Live recipe

    Recognize against the recipe

    The processor compares every flake to the accepted color range and the named reject classes from your sample test — clear versus off-color, opaque, black or aged — and makes an accept/reject call in real time.

  4. 04
    Air ejection

    Time & eject

    A fast valve bank fires a precise air pulse the instant an off-spec flake reaches the ejection line, knocking it into the reject channel while accepted flakes fall straight through. Timing is tuned to flake size and chute speed.

  5. 05
    Quality check

    Verify & re-sort

    Accepted and reject streams are checked against your quality target. Tighter targets can run a second pass to lift purity, or route the reject stream to recover a saleable color fraction instead of losing it.

Buyer questions

What buyers ask before specifying a MAS-C.

Straight answers on purity, throughput, what MAS-C can and cannot separate, and how a sample test turns into a quoted configuration.

Is MAS-C for whole bottles?

No. MAS-C is framed for flakes or prepared plastic pieces. Whole bottles should be reviewed under MAS-B.

Can MAS-C separate PET from PVC?

Not as a color-sorter claim. PET/PVC material separation should be reviewed under MAS-P or MAS 3D where the selected configuration supports it.

Can one color recipe work for every flake stream?

No. Different polymers, colors, particle sizes, dirt and moisture levels need recipe review.

Are throughput and purity published here?

No. Those values require representative sample testing and confirmed configuration.

Real sample testing

Use your own flake color targets before finalizing the sorting recipe.

A MAS-C project should start from real feed, accepted color fractions, off-color pieces and borderline material from the line.
