The company is involved in industries such as automobiles, railways, agricultural machinery, construction machinery, electrical appliances, and medical equipment.Our FactoryCompany AdvantageAfter-Sales ServicePackaging & ShippingI. Preparations before Packaging1. Casting pre-treatmentSurface 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 DetailsIndividual protectionEdge 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 designBuffer 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 PackagingBox 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.FAQQ: Are you a factory or a trading company?A: We are a company that integrates industry and trade.
