Material use
Use this ready-to-process compound directly, or blend it with compatible virgin ABS in any proportion to adjust the fiber concentration and molded appearance. Run a molding trial after changing the blend ratio.
Coffee Ground Fiber ABS Composite
WYC-ABS PA757520
Coffee Ground Fiber ABS incorporates processed spent coffee grounds into an ABS base, producing a deep brown-gray material with fine dark particles and natural color variation. A mild roasted-coffee character may remain in the material, reinforcing its distinctive sensory identity. The ABS matrix gives molded parts rigidity and crisp form definition, while the coffee content creates a dense, stone-like visual texture. Typical uses include small appliance housings, serving trays, desk accessories, retail display components and decorative interior parts.

Usage Guidelines and Processing Notes
Color matching
Color matching is supported within a limited range. Because the natural base is dark, select dark color families; pale or bright colors cannot reliably cover the original tone. Confirm the target with a molded color sample.
Processing method
Injection molding.
Mold care
Use hardened, corrosion-resistant mold steel. Clean the mold promptly after processing, because plant-fiber composite material left in the tooling can corrode the mold if it is not removed in time.
Reference Processing Temperatures
| Stage | Reference setting |
|---|---|
| Drying | 90–100 °C for 5–6 h |
| Rear zone | 165–175 °C |
| Middle zone | 175–180 °C |
| Front zone | 180–195 °C |
| Nozzle | 180–195 °C |
| Mold | 60–90 °C |
Important: These settings are starting references only. Adjust them for the machine, mold, part geometry and residence time. Excessive temperature or residence time can scorch or carbonize the plant fiber; begin at the lower end and increase only as needed.
