Zinc Alloy Die Casting Fasteners for WPC Door (Male & Female Corner Code)

1. Application Scenarios

Zinc alloy die-casting fasteners are widely used in WPC (Wood Plastic Composite) doors and frames for structural connection and reinforcement. Typical application scenarios include:

• WPC door corner assembly
  Male & female corner codes are used to firmly connect door panels and frames, ensuring stability and precise alignment.

• Interior & exterior WPC doors
  Suitable for residential, commercial, and industrial buildings where moisture resistance and durability are required.

• Furniture and modular structures
  Applied in cabinets, wardrobes, and modular WPC systems for quick and strong joint connections.

• Construction hardware systems
  Commonly used in door/window accessories, improving installation efficiency and long-term reliability.

Thanks to zinc alloy’s high strength, corrosion resistance, and dimensional accuracy, these fasteners perform well in humid or variable environments.

2. Production Process

The fasteners are manufactured using precision zinc alloy die casting, a highly efficient process for producing complex and high-accuracy components.

Main steps include:

1. Material Preparation
   High-quality zinc alloy (such as Zamak series) is melted at controlled temperatures (approx. 420–450°C).

2. High-Pressure Die Casting
   Molten metal is injected into a precision steel mold under high pressure, forming the required shape with tight tolerances.

3. Rapid Solidification
   The material cools and solidifies quickly, enabling high production efficiency and consistent quality.

4. Ejection & Trimming
   Finished parts are ejected from the mold, and excess material (flash) is removed.

5. Surface Treatment
   Optional processes such as electroplating, polishing, or coating enhance corrosion resistance and appearance.

6. Inspection & Quality Control
   Each batch undergoes dimensional and visual inspection to ensure precision and durability.

Key advantages of this process:

• High precision (tight tolerances up to ±0.05 mm)

• Smooth surface finish with minimal machining

• Fast cycle time (mass production capability)

• Ability to produce complex shapes and integrated designs
