Die Casting & Forging Solutions for Complex 3D Shapes, High Strength & Precision Bag Hardware
Complex 3D Shaping & High-Strength Metal Forming for Custom Handbag & Luggage Hardware
Two Core Forming Technologies for Different Design & Performance Goals
Die casting and forging solve different structural problems: one prioritizes complex shape replication, the other prioritizes internal density and load-bearing strength.
Die casting and forging are the two core metal forming technologies for handbag and luggage hardware, each designed for different design requirements and performance goals. At Junhao Hardware, with 19+ years of specialized manufacturing experience, we operate full in-house die casting and forging production lines, delivering precise, stable and consistent metal forming solutions for global brands and leather goods manufacturers.
High pressure die casting excels at creating complex, detailed three-dimensional shapes with smooth surfaces, making it ideal for decorative hardware, locks and logo parts. Cold forging compresses metal grain structure to produce ultra-strong, dense and durable load-bearing parts, perfect for hooks, chains and structural fittings.
All forming processes strictly follow ISO 9001 quality management standards, with strict dimensional tolerance control and full in-process inspection to ensure every part meets brand assembly and performance requirements.

High Pressure Die Casting
Die casting is the most widely used forming process for fashion bag hardware. It injects molten non-ferrous metal into high-precision steel molds under high pressure, replicating intricate contours, embossed logos and irregular curved structures with high accuracy.
Key Advantages
- Supports extremely complex 3D shapes, fine relief details, hollow structures and custom decorative patterns
- High dimensional accuracy and excellent repeatability for mass production
- Smooth as-cast surface base, ideal for subsequent high-quality polishing and plating
- Fast production cycle and high efficiency for large batch orders
- Compatible with zinc alloy, brass and most non-ferrous metals
Handbag turn locks, magnetic clasps, buckles, D-rings, logo plates, decorative trims and all complex 3D structured metal fittings.
Cold Forging
Cold forging is a high-strength forming process that shapes solid metal at room temperature through extrusion and impact pressure. It compresses and refines the internal grain structure, resulting in denser, harder and more durable parts compared to casting.
Key Advantages
- Superior structural strength and higher tensile load capacity
- Dense internal structure, no porosity or air holes, eliminating hidden breakage risks
- Excellent wear resistance and longer service life under frequent use
- Stable dimensions, tight tolerance control and high surface finish accuracy
- Ideal for safety-related and load-bearing hardware components
Heavy-duty spring hooks, load-bearing D-rings, chain links, strap connectors, tactical bag hardware and high-strength structural fittings.
