Rectangular Aluminum Foil Container Production Process and Features
The production process of aluminum foil containers mainly includes the following steps: rolling, stamping, trimming, curling and necessary surface treatmef aluminum plates.
The specific steps are as follows
- 1. Billet preparation: Large aluminum ingots are rolled to reduce thickness and extend into the required aluminum foil coils.
- 2. Stamping: Using special molds, the aluminum foil coils are cold stamped into the required shapes, such as round, square, etc., at one time by stamping. Since we are a manufacturer that mass-produces aluminum containers, container foils are usually produced in the form of giant rolls. Then, the giant aluminum foil rolls are straightened to avoid misalignment during the stamping process, which requires manual inspection at all times.
- 3. Trimming: The formed aluminum foil container is trimmed to remove excess parts and ensure neat edges.
- 4. Curling: In order to increase the strength and sealing of the container, curling is usually performed to form a curling structure at the mouth of the container.
- 5. Surface treatment: Surface treatments such as coating and printing can be performed as needed to increase aesthetics or functionality.
- 6. Finished Product Inspection: Quality inspection of produced foil containers to ensure compliance with standards.
