Housewares
Houseware parts often take calcium carbonate as a filler to bring cost down. Calcium carbonate and resin differ widely in bulk density, so however well the tumbler blends them, one knock in the hopper and the filler settles out — the parts moulded at the start of a batch do not match the ones at the end.
How MegaColor deals with it
- The dual-material model meters each raw material in its own weighing chamber and blends them in a small chamber afterwards, leaving no time for separation
- Blends on demand instead of pre-mixing a large tumbler batch, which removes hopper settling at the source
- Nothing is left over — zero waste, with no tens of kilograms of pre-blended material sitting in a tumbler at changeover
Which model this industry usually takes
This is the common choice, not the only answer — resin temperature and throughput per machine are what actually decide the model.
Common choice: MegaColor 5th Gen Dual-Material
- Resin plus calcium carbonate counts as two raw materials, so each gets its own weighing chamber before they are blended
- Resins: PP / PE / PS / TPE and similar low-temperature resins
- Throughput: 50–70 kg/h
- Dosing configuration: Two materials standard (expandable to 4 with add-on modules)
When to choose a different model
- Running high-temperature resins (ABS / PC and similar) → same model in the high-temp configuration, see the model codes
- More than 70 kg/h per machine → large-capacity model
- Two powders to dose → dual-powder model
- Several raw materials to dose → dual-material model
Industry experience is no substitute for a trial run. Within one industry, every plant has its own resin grades, pigment suppliers and loading ratios. We do not conclude anything from "everyone in this industry uses model X" — send us the resin and powder you actually run, we test on your material and settle the model once there is data. There is no charge for this step.

The trial run is free. We talk model and price once the data is in.
