Our Packaging & Logistics Assurance
We take a full-cycle approach to protect your products—from tailored packaging solutions to reliable logistics partnerships—ensuring safe and on-time delivery worldwide.
1. Comprehensive Packaging Solutions
We offer multi-tiered packaging options, customized to product size, material, and shipping mode, to eliminate damage risks during transit:
Wooden Pallets/Crates: Designed for heavy/large heads, with reinforced structures to resist deformation and collision in long-haul shipping.
Iron Pallets/Containers: Ideal for industrial-grade heads, providing superior durability against external pressure and moisture in harsh environments.
Nylon Bags: Used as inner packaging for small-to-medium heads, isolating dust and minor impacts while maintaining breathability to prevent moisture buildup.
Polishing Protective Films: Applied to precision-machined/polished heads, forming a scratch-resistant layer that preserves surface finish and avoids post-delivery cleaning.
2. Strict Packaging Process Standards
Every package undergoes a 3-step quality check to ensure compliance with international shipping norms (ISO 12944, ASTM D4169):
Pre-Packaging Inspection: Check product surface condition and dimensions to select the right packaging type.
Secure Sealing: Use industrial-grade straps, cushioning materials (e.g., foam inserts), and waterproof tape to fix the product in place.
Labeling & Documentation: Attach clear labels (fragile, weight, handling instructions) and complete shipping documents for smooth customs clearance.
