Dmetal Power Coating Aluminum Die Casting Services CNC Machining & Painting Services for Aluminum Casting

In modern industrial manufacturing, Dmetal's integrated aluminum die casting services with power coating and CNC machining capabilities represent a comprehensive solution for high-quality aluminum components. Our services combine advanced die casting technology with precision machining and superior surface treatment to deliver components that meet the most demanding industrial specifications.

Material Selection and Properties
We specialize in aluminum alloys including ADC12, A380, and A413, which provide excellent fluidity for complex geometries and superior mechanical properties. These materials feature:

• Tensile strength: 280-320 MPa

• Yield strength: 130-160 MPa

• Elongation: 3.5-5.5%

• Excellent thermal conductivity (96-140 W/m·K)

• Good corrosion resistance and lightweight characteristics

Advanced Manufacturing Process
Our integrated manufacturing approach begins with high-pressure die casting using machines with clamping forces from 250 to 1650 tons. The process incorporates:

• Precision mold temperature control systems (±5°C)

• Vacuum-assisted casting for reduced porosity

• Automated extraction and quenching systems

• Real-time process monitoring with data acquisition

CNC machining centers perform secondary operations with positioning accuracy of ±0.01mm, handling complex features including threaded holes, precision bores, and critical mounting surfaces.

Surface Treatment Excellence
The power coating process employs advanced pretreatment with zirconium-based nanotechnology conversion coatings, followed by electrostatic application of epoxy-polyester hybrid powders. Our coating system delivers:

• Film thickness: 60-120 μm

• Adhesion: 0 grade (ASTM D3359)

• Impact resistance: 50 kg·cm

• Salt spray resistance: 750-1000 hours

• Color consistency: ΔE≤1.5

Quality Assurance and Applications
Our comprehensive quality system includes:

• X-ray inspection for internal integrity

• CMM verification for dimensional accuracy

• Coating thickness measurement at multiple points

• Performance testing per ASTM and ISO standards

These services support diverse applications across automotive components, electronic enclosures, industrial machinery parts, and consumer products requiring durable, precision aluminum components with superior aesthetic finish.
