Manufacturing Flow of 5th Wheel Bumper Kit (Holland H-3510)
- 1. Alloy Melting: Selection of high-grade cast steel, melted to precise chemical standards (e.g., C≤0.25%, Mn≤1.3%, Cr>0.16%).
- 2. Precision Casting: Use of advanced sand & resin molds ensures uniformity and reduces micro-pore defects. Preheated molds (up to 500°C) improve grain structure for enhanced energy absorption.
- 3. CNC Machining: Multiaxis CNC equipment (1μm tolerance) refines coupler plates, guides, and pivot bores. Guarantee of absolute interchangeability among 5th wheel hitch parts.
- 4. Surface Coating: Electrostatic powder with an extra zinc-rich base (anodic protection) yields ISO 9227 compliance for >480hr salt fog resistance.
- 5. Inspection & Testing: 100% ultrasonic crack detection, dimensional verification, and load simulation (up to 185kN static, 130kN dynamic) per ANSI B30.1/ISO 1726.
