Hardware decoration solutions

Die casting technology offers significant advantages in the field of hardware decorative parts, enabling complex shapes, high precision, and high surface quality. It is suitable for building decoration, home hardware, lighting, bathroom fixtures, and other fields. The following are key solutions and technical points for die-cast hardware decorative parts.

1. Core Application Scenarios

(1) Architectural Hardware

Door handles, pulls (Zinc alloy/aluminum alloy die casting, surface plating or oxidation).

Curtain wall decorative parts (Aluminum alloy die casting, anodizing or spraying).

Stair handrail accessories (Brass/aluminum alloy die casting, antique plating).

(2) Home Decoration Pieces

Furniture hardware (Cabinet door pulls, hinge bases, decorative fasteners).

Lighting accessories (Lamp shade brackets, chandelier decorative parts).

Mirror frame/picture frame decoration (Zinc alloy die casting + imitation gold plating).

(3) Bathroom Hardware

Faucet handles (Zinc alloy die casting, chrome-plated surface).

Shower head bracket (Aluminum alloy die casting, corrosion-resistant treatment).

Bathroom hooks/towel racks (High-gloss/matte surface treatment).

(4) Automotive/Yacht Decorative Parts

Car logos, air intake grille decoration (Aluminum alloy die casting + plating).

Yacht handrails/porthole trim (Salt spray corrosion resistance treatment).

2. Material Selection

3. Key Process Optimization

(1) High-gloss surface die casting (mirror effect)

Mold polishing (Ra≤0.05μm) + High-precision die casting , reducing subsequent processing.

Suitable for high-end bathroom hardware, automotive decorative parts.

(2) Complex texture die casting (imitation wood grain, stone grain)

Etched molds or in-mold transfer (IMR) , directly die-casting the texture.

Used for antique furniture hardware, art decorative parts.

(3) Insert die casting (metal + other materials combined)

Metal + resin (Such as decorative parts inlaid with crystal glass).

Metal + LED (Such as luminous door handles).

(4) Ultra-thin die casting (0.5-1.2mm)

Suitable for lightweight decorative parts (such as lampshade brackets, openwork carvings).

4. Surface Treatment Technology

5. Industry Challenges and Solutions

6. Innovative Application Cases

✅ LV luggage hardware: Zinc alloy die casting + 24K gold electroplating, luxurious texture.

✅ Apple flagship store door handle: Ultra-thin aluminum alloy die casting + anodizing, minimalist style.

✅ Swarovski crystal lighting: Zinc alloy die-cast frame + inlaid crystals.

✅ Tesla Cybertruck door trim: Die-cast aluminum + matte black oxidation, futuristic design.

7. Future Trends

🔹 Finer textures: 3D laser engraving molds to achieve micron-level patterns.

🔹 Smart decorative parts: Die-cast metal + embedded electronics (such as touch-sensitive door handles).

🔹 Environmentally friendly surface treatment: Cyanide-free electroplating, water-based coatings replace traditional processes.

🔹 3D printing + die casting combination: Rapid prototype verification + mass production.

Summary

The core of die-cast metal decorative parts lies in Appearance, durability, and cost balance.

High-end solution: Zinc alloy/PVD coating (luxury goods hardware).

High cost-effective solution: Aluminum alloy/powder coating (home decoration parts).

Special effect solution: Antique brass finish (retro style).

Companies can choose suitable materials, processes, and surface treatments according to market demand to create differentiated products.
