Ning Bo AiNoLink Technology Co. Ltd. is a comprehensive industrial and trade enterprise integrating produ-

ction and trade. It has its own metal processing production base and a mature domestic sales network.

Our company is client-oriented, leveraging a robust supply chain network and professional market insights to provide customers with stable quality and timely delivery products and services. We also assist custom-

ers in reducing costs and increasing effciency, thereby establishing long-term strategic partnerships with them.

The products currently offered by the company include, but are not limited to, various metal products such as stainless steel, low-carbon alloy steel, ductile iron, gray iron, aluminum, copper, etc. They involve multiple processes such as casting, forging, stamping,welding, as well as surface treatment processes like heat treatment, electroplating, oxidation, blackening, and powder coating. The company is involved in industries such as automobiles, railways, agricultural machinery, construction machinery, electrical appliances, and medical equipment.

I. Preparations before Packaging
1. Casting pre-treatment
Surface cleaning: Remove the molding sand, burrs and oil stains from the surface of the casting, ensuring no residual impurities (using shot blasting or chemical cleaning).
Anti-rust treatment: Customized protection plan based on transportation environment:
Maritime transportation / High humidity environment: Spray epoxy zinc-rich primer + polyurethane topcoat (coatingthickness ≥120μm).
Short-term storage: Apply economical anti-rust oil for temporary protection.
Drying treatment: Ensure that the moisture content of the castings is ≤ 0.5%, to prevent internal rusting.

II. Core Packaging Process and Details
Individual protection
Edge protection: Hard edges are covered with EPE pearl cotton or custom foam corner protectors (thickness ≥20mm) to prevent puncturing the box.
Precision surface coating: Apply fluorocarbon spray to the surface and cover it with a PE protective film (such as for revolving door ceiling panels) to prevent scratches.
Moisture-proof measures: Place silica gel desiccant inside the box (quantity: 1kg per cubic meter) or adopt a perforated design (the stainless steel castings need to be breathable to prevent condensation).

2. Internal reinforcement design
Buffer filling: Fill the gaps with foam beads, paper scraps or air cushions to ensure that the casting does not shift. Load-bearing support: For overweight components (such as 70-kilogram castings), a "calcium plastic hollow board + directional reinforcing ribs" structure is adopted, which increases the load-bearing capacity by 40%. Layered isolation: When stacking in multiple layers, use solid wood pillow blocks for separation to prevent component collisions (such as in the packaging of rotating door profiles).

3. External Packaging
Box structure:
Wooden box: Five-layer composite board (thickness 0.9 cm) + metal snap fasteners for locking, with steel frame reinforcement at the bottom.
Calcium plastic box: Modular assembly, empty box can be folded to save storage space.
Sealing treatment: The top of the box is covered with double-laver moisture-proof film, and the seams are sealed with waterproof adhesive tape.
ldentification Specifications:
Printing enterprise logo, casting name/number, center of gravity symbol , rain protection sign.
Attach warning labels (such as"Sharp Edges") and hoisting indication marks.
