This ship-shaped Metal Keychain is based on zinc alloy and is formed through 3D modeling and precision die-casting technology to present details such as the cruise ship's hull, deck, chimney, etc. The size is usually 5-8 cm (suitable for handheld viewing). Its core processes include:
?
3D shape design
Features: The hull structure is designed using 3D modeling software (such as Rhino, SolidWorks) to ensure accurate proportions and smooth lines. Through multi-angle split die-casting, complex shapes such as the curvature of the ship's side and the texture of the deck are achieved to avoid the monotony of traditional flat keychains.
Technical details: Mold development needs to consider metal fluidity, key parts (such as bows and chimneys) need to increase wall thickness to prevent deformation, and at the same time reserve areas for engraving and baking paint.
?
Gold plating process
Features: imitation gold layer (such as zinc alloy) is electroplated on the surface of the metal substrate, with a thickness of 0.5-1 micron, and a glossiness close to that of a mirror, highlighting the luxurious texture. The gold-plated layer can effectively isolate the air and delay oxidation discoloration.
Technical details: Before electroplating, 12 pretreatment processes such as degreasing, pickling, and activation are required to ensure the adhesion of the coating; after electroplating, the durability is verified by salt spray test (48 hours without corrosion).
?
?
Paint coloring process
Features: Spray high-transparency epoxy resin paint on the surface of the gold-plated layer, and restore the real color of the cruise ship (such as white hull, blue deck, red chimney) through gradient spraying or layered coloring. The hardness of the paint layer reaches 3H and can resist daily scratches.
Technical details: The three processes of "primer + midcoat + topcoat" are adopted, and the baking temperature of each layer is controlled at 160-180℃ to ensure color saturation and adhesion; key parts (such as ship windows) are transparent through masking spraying.
?
Engraving process
Features: Engraving brand LOGO, ship name or route map on the surface of the hull or deck, with a depth of 0.1-0.3 mm, clear lines and no burrs. The engraving process is combined with gold plating and paint to form a three-dimensional visual effect of "relief + color".
Technical details: Laser engraving or CNC precision engraving is used. Before engraving, the path needs to be preset in the 3D model to ensure seamless connection with the overall shape; polishing is required after engraving to avoid scratching fingers.

Application field of 3D Printed Metal Keychain
High-end cruise retail
Scenario: Sold as cruise souvenirs in duty-free shops and gift shops on board, and the target customers are middle- and high-income tourists (such as business class passengers and family tourists). The keychain can be designed to be the same style as the cruise ship, engraved with the ship name and route, and become a "mobile cruise business card".
Case: An international cruise company launched a customized keychain on the "Quantum of the Seas", engraved with the ship name and the "Shanghai-Tokyo" route map. After listing, the monthly sales exceeded 2,000 pieces, and the repurchase rate reached 15%.
?
Cultural and tourism IP derivatives
Scenario: Combine popular tourist cities or landmarks (such as the Burj Al Arab in Dubai and the Sydney Opera House) to develop city-themed keychains. Carve the outline of the landmark and the name of the city to attract tourists to collect.
Case: A tourism bureau launched a series of "City Cruise" keychains, combining local landmarks with cruise ship shapes, and sold them at airports and scenic spots. They have become must-buy souvenirs for tourists and have driven surrounding consumption.

Custom Keychain Maintenance Guide
?
Cleaning
Use a soft brush (such as a toothbrush) to gently remove dust and avoid scratching with hard objects; if stained, wipe it with a cotton swab dipped in a small amount of neutral detergent (such as dishwashing liquid), and immediately wipe it with a dry cloth to prevent moisture from penetrating into the gold-plated layer.
?
Moisture-proof
For long-term storage, it is recommended to put it in a moisture-proof box or sealed bag and place a desiccant (such as a silica gel bag); if the keychain is exposed to rain or sweat, it must be wiped dry with a dry cloth immediately to prevent the gold-plated layer from oxidizing and blackening.
?
Scratch-proof
Store it separately in a velvet bag or a special jewelry box to avoid mixing with hard objects such as keys and coins; if there are slight scratches on the surface of the keychain, wipe it gently with a cotton cloth dipped in a small amount of metal polishing paste (such as AutoSol) to restore the gloss.
?
Anti-chemical corrosion
Avoid contact with chemicals such as perfume, cosmetics, alcohol, etc. to prevent corrosion of the gold-plated layer and paint; if accidentally contacted, rinse with clean water immediately and wipe dry.
