Metal Combination Lock for Coordinated Luggage Hardware
The Zinc Alloy Luggage Lock is a three-digit combination lock buckle made for luggage applications. Its main buckle body is manufactured from zinc alloy, providing a metal appearance and a structure suitable for different surface-finishing requirements.
The product does not require a key. Users open and close the lock by operating the three combination wheels. It is suitable for briefcases, business cases, vintage-style luggage, and other cases where the lock needs to match the appearance of the surrounding hardware.
Unlike a small portable luggage padlock, this product is more suitable as an installed hardware component within the luggage structure. It can provide closure, basic protection, and a decorative metal detail at the same time.
Surface Finishes for Different Luggage Designs
Zinc alloy can be processed with different surface finishes. Available choices include bright chrome, satin chrome, satin nickel, imitation gold, and black.
These finishes allow the lock to coordinate with luggage handles, hinges, corner protectors, and other metal accessories. Buyers may select a finish according to the case material, hardware style, intended appearance, and product positioning.
The Zinc Alloy Luggage Lock can be used for medium- and higher-positioned luggage products, briefcases, business cases, and retro luggage designs. During product selection, buyers should confirm the installation position, closing method, case material, and color of the other hardware components.
Product materials can be arranged for ROHS material testing.

Product Development and Custom Samples
Zhejiang Tongtai Lock Industry and its predecessor have more than 20 years of experience in luggage locks and related hardware products. The factory supports standard product purchasing, development from samples, structural adjustments, brand marking, and packaging design.
Buyers may provide technical drawings, a luggage sample, or an existing lock prototype. The research and development team can evaluate the dimensions, installation method, and required product changes.
For an existing model, a customized sample with laser logo processing can normally be completed within 2–3 days. A packaging sample normally takes around one week. The development time for a new product depends on the structural complexity.
Regular products have no minimum order quantity requirement. Custom packaging normally requires 1,000–2,000 pieces. Different colors or models may be combined in one order when production conditions allow.
Production Inspection and Shipment Support
The factory checks zinc alloy buckle dimensions, surface color, appearance, combination-wheel operation, locking and opening functions, connection strength, and assembly quality.
Product dimensions are inspected after processing. Electroplated or otherwise finished parts are checked when they return to the factory. Process inspections are carried out during production, and every finished product is inspected before packaging.
For approximately 10,000 standard pieces, the usual production lead time is around 25 days. Progress photos may be provided when production scheduling begins, when the first finished products are completed, during the middle of production, and after packaging.
The Zinc Alloy Luggage Lock is packed in an inner box and an outer carton. Stretch film can be added for pallet shipments. Regular locks have a one-year warranty for damage not caused by improper use, supporting later quality follow-up and repeat purchasing.
