Technology and Patents
A patent list should not be a wall of certificate photos. This page gives you the title and application number of every granted patent, so you can look any of them up yourself in the CNIPA database.
The rights holder is the parent company. These patents are filed under Zhejiang Sunup Technology Co., Ltd. (NEEQ: 873579). MegaColor is Sunup's color powder dosing machine brand and sales entity. Search under Sunup Technology, not MegaColor.
Patent titles below are given in English for readability, with the original Chinese alongside. The filing of record is in Chinese — use the application number when verifying.
Invention patents (2, both granted)
Invention patents in China take years to examine and are substantially harder to obtain than utility models. These two cover the core machine architecture.
| Patent title | Application no. | Filing date | Type | Status |
|---|---|---|---|---|
| Fully Automatic Plastics Colouring Machine全自动塑料上色机 | 2016106305290 | 2016-08-03 | Invention | Granted |
| Modular Plastics Colouring Machine一种组合式塑料上色机 | 2020102043524 | 2020-03-21 | Invention | Granted |
Utility model patents (18, all granted)
These concentrate on the color powder container, the metering and powder-delivery assembly, valve components, the mixing chamber and the cooling mechanism — in other words, the parts that actually determine dosing consistency and changeover time.

Where several entries share a title (for example three filings of "Colour Powder Assembly for Plastics Colour-Dosing Machines"), these are separate filings for different structural solutions. The application numbers differ — they are not duplicate counts.
