Iron Oxide Pigment Manufacturing
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Where Science Meets Industrial Scale
Deqing Demi Pigment Technology Co., Ltd. is more than a supplier; we are a "Primary Manufacturer." Our factory is a hub of chemical engineering excellence, where we transform raw iron into high-purity pigments. We control every step of the process, from the initial raw material selection to the final micronization. This vertical integration allows us to offer superior quality control and price stability, as we are not dependent on external pigment processors.
Manufacturing Excellence Applications
- Core Pigment Production: Creating the fundamental reds, yellows, and blacks.
- Custom Calcination: Developing high-heat stable oranges and browns.
- Micronization: Achieving ultra-fine grinds for technical applications.
- Surface Modification: Chemically treating pigments for specific resin types.

Q: Do you use the Penniman process?
A: We utilize several advanced synthesis methods, including precipitation and calcination, depending on the specific crystal shape required for the grade.
Q: Are your manufacturing processes eco-friendly?
A: Yes, we adhere to strict environmental standards, recycling our process water and minimizing energy consumption.
Custom Synthesis Services
We can "Tune" our manufacturing line to produce a unique shade or particle size specifically for your proprietary product.
Factory Audits: We welcome our long-term partners to visit our manufacturing facility and audit our quality management systems (ISO 9001/14001) firsthand.
The Science of Crystal Growth
In manufacturing, we focus on "Nucleation and Growth." By controlling the "Seeding" process, we determine the final size of the pigment particle. Larger crystals result in "Duller, Deeper" tones, while smaller crystals create "Brighter, Cleaner" hues. We use real-time pH monitoring and oxygen-injection control to ensure that every crystal grows uniformly, which is the key to our industry-leading tinting strength and color purity.
