Key Features

Superior Design Flexibility: Investment casting (lost wax) and sand casting processes enable the production of one-piece complex geometries (irregular shapes, multi-way ports, integrated reinforcing ribs) that eliminate the need for multiple welded components, reducing assembly complexity and weak points.

High-Toughness Cast Material: Ductile iron (QT450-10) variants offer excellent impact resistance and ductility (10% elongation), avoiding brittle fracture under dynamic loads—outperforming traditional gray iron. Cast carbon steel (ZG230-450) provides enhanced tensile strength for medium-heavy load applications.

Precision Machined Interfaces: Critical connection surfaces (bolt holes, pipe sockets) are CNC-machined to tight tolerances (±0.2mm), ensuring a secure, gap-free fit with standard steel pipes (DN20–DN120), profiles, and fastener accessories. Machined bearing surfaces reduce wear and ensure long-term connection stability.

Multi-Layer Corrosion Protection: Undergoes a three-stage anti-rust process: (1) Shot blasting for surface smoothness; (2) Anti-rust primer coating; (3) Hot-dip galvanization (≥100μm) or epoxy powder coating. This system provides long-term protection against rust, moisture, and mild chemical corrosion in outdoor and industrial environments.

Cost-Effective Customization: Casting requires lower tooling costs than forging for complex shapes, making it the most economical solution for small-to-medium batch custom fasteners (e.g., specialized scaffolding couplers, unique frame connectors).

Universal Compatibility: Available in a full range of configurations (right-angle, cross, T-type, multi-way, rotary) to match diverse connection needs. Compatible with bolted, pinned, and welded installation methods, seamlessly integrating with existing structural systems.
