Manufacturing Process
The Raw Materials
The process starts with the raw materials. These plastics include PC, ABS and PP, which are all popular when making luggage.
Plastic Sheet Extrusion
Small plastic pellets are melted and turned into large flat sheets using a plastic sheet extruder machine. How It Works: The machine heats and melts the pellets It presses the melted plastic into flat sheets of the required thickness and surface texture. The machine then cools and trims the sheets to size These sheets form the outer shell of the suitcase Artificial intelligence monitors the process to ensure each sheet has the same thickness, improving quality.
Creating the Shell of the Suitcase
Luggage shell manufacturing relies on two primary processes: vacuum forming and injection molding. These processes shape materials like ABS, PC, RPET and PP into durable and visually appealing suitcase shells.
Vacuum Forming:
Injection Molding:
Aluminum Molds
The vacuum-forming machine uses aluminum molds to shape the plastic shells. Aluminum molds are lightweight and cool quickly, saving time and energy. CNC machines make these molds with high precision, ensuring each suitcase looks perfect.
Cutting and Punching
The machine trims and cuts the formed suitcase shells to fit. It punches holes for handles, wheels, and locks. How It Works: CNC cutting machines follow pre-set designs to trim the edges and cut holes. The machine punches holes accurately to attach handles, wheels, drawbars and TSA locks. We use the heavy equipment like CNC machines- Wenzhou Chaoxu Machinery, ensures accurate cutting and punching. Real-time data helps machines adjust, reducing waste
Injection Molding for Accessories
Small parts like wheels, handles, and feet are made using injection molding. How It Works: Plastic is melted and injected into molds to form the parts. The molds cool and someone ejects the parts.
Assembly
The trimmed shells are assembled with linings, zippers and other components. How It Works: Sewing machines attach fabric linings and zippers to the shells. Factory workers install handles, wheels and TSA locks using rivets or screws. This step combines all the parts into a complete suitcase.
Final Product
The finished suitcase goes through quality checks before being packaged and shipped. Inspectors check the suitcase for matching situation of front and rear shells, scratches, dents, or loose parts. If everything looks good, the suitcase will be packed for delivery. Quality control ensures the customer gets a durable and well-made product.
