If you need long-lasting metal parts that won't rust and look great, Color Powder Coated Aluminum Die Casting is the ultimate solution. We are experts at precision die casting and professional powder finishing here at Shenzhen Ruiyihang Technology Co., Ltd. Our engineering-based method guarantees measurement accuracy within ±0.10 mm for castings and ±0.02 mm for machined areas. Our coating thickness stays the same at 60–120 μm. We take your ideas and turn them into high-performance finished goods. Our average engineering experience goes back 15 years, and we guarantee delivery within 7 days (as fast as 3 days for simple parts).
It's not just parts. Full manufacturing options are given to you, along with direct expert help.
Three important steps make up our process. First, materials like ADC12 or A380 are used for aluminium die casting. Next, precise CNC cutting makes important parts even better. Lastly, the finish you want is made by skilled powder painting.
There are big benefits to this combo. Your parts become very resistant to rust. The layer can stand up to rough conditions. The colours stay bright and true. The surface is much more resistant to chipping and fading than paint.
Color Powder Coated Aluminum Die Casting can be used for many things. The protective finish is good for electronics housings. Parts for cars get stronger over time. Frames of industrial tools can withstand being exposed to the elements. Coffee machine housings look good and do their job.

We start with high-quality aluminum alloys. Material selection depends on your specific requirements. Common choices include ADC12 and A380, known for excellent castability and mechanical properties.
Die casting creates complex geometries efficiently. Your parts take shape with good dimensional consistency. This stage establishes the foundation for subsequent processes.
After casting, CNC machining refines critical features. Drilling, tapping, milling—whatever your design requires.
We maintain tight tolerances during machining. This precision ensures proper fit and function. Our engineers consider coating thickness during this stage, guaranteeing final dimensions meet your specifications.
Proper preparation determines coating quality. Parts undergo thorough cleaning. Deburring removes sharp edges. Bead blasting creates ideal surface texture when needed.
This stage ensures strong coating adhesion. Skipping these steps compromises durability. We never cut corners here.
Electrostatic powder application distributes coating material evenly. Charged particles adhere uniformly to part surfaces.
Heat curing follows application. Parts enter curing ovens where powder melts and flows. This creates a smooth, continuous protective layer.
Coating thickness stays within your specified range. Standard thickness runs 60–120 μm. Thicker coatings provide enhanced protection when required.
Every batch undergoes inspection. We check dimensional accuracy post-coating. Coating thickness receives verification. Adhesion testing confirms durability.
Color matching follows your specifications. Whether RAL, Pantone, or custom standards, consistency matters. Visual inspection catches surface imperfections before shipping.

Q: What is the product?
It combines aluminum die casting with color powder coating to produce durable, corrosion-resistant parts with customized surface colors.
Q: Can die cast parts be CNC machined before powder coating?
Yes, CNC machining such as milling, drilling, and tapping is commonly applied before color powder coating.
Q: What colors are available for powder-coated die-cast parts?
Standard colors include black, white, gray, and custom colors can be applied depending on project requirements.
Q: How does powder coating compare to painting?
Powder coating provides superior durability, better corrosion resistance, and longer-lasting color compared to traditional liquid painting. The finish resists chipping, fading, and environmental damage more effectively.
Q: What industries benefit most from these parts?
Electronics, automotive, industrial equipment, consumer appliances, and architectural applications all benefit from the durability and appearance of the product components.
