Premium bottle closure supplier said that although the beer bottle cap is just a very inconspicuous small cap, it plays a very important role and has functions such as preservation and sealing. So, do you know how beer bottle caps are produced? What is the production process of beer bottle caps?
Premium bottle closure supplier said that beer bottle caps are produced by a capping machine, which consists of a bottle holder turntable, a capping head, a capping slide, a height adjustment device, a hopper, and a blanking chute.
The production process of beer bottle caps: sending caps – positioning – pressing caps – reset. Check out the production video below:
Beer bottle caps not only define the diameter of the neck, but also the shape of the edge of the cap, as well as the material of manufacture.
Premium bottle closure supplier said that One of the requirements of the bottle cap is good sealing, which means more pleats; at the same time, the bottle cap must be firm, which means that the number of pleats cannot be too many to ensure that each pleat has a larger contact surface area.
However, the problem of rust in the production process of beer bottle caps has always been a big problem for manufacturers.
To prevent beer bottle caps from rusting, Premium bottle closure Supplier suggest that :
Quality control of bottle cap material sheet
Premium bottle closure supplier said that the corrosion resistance of the plate is mainly guaranteed by its own passivation quality and the quality and thickness of tin plating, but these two processes are completed by the steel mill, and the aircraft cover manufacturer needs to inspect the quality of the plate.
2 Reduce the damage to the anti-rust layer of the bottle cap during the beer production process
The punching cross-section without anti-rust layer is caused by the limitation of the current inner bottle cap processing technology.
Premium bottle closure supplier said that as a beer manufacturer, there is no good solution. Some companies, such as Japan, can apply an anti-rust layer to the cross-section after the sheet is punched according to the customer’s requirements, and then stamped and molded.
The structure of the steel bowl
The steel bowl is a hollow cylinder, which is composed of ordinary steel body and manganese steel or hard alloy steel. Enter the steel bowl, the upper part is cylindrical, and the diameter of the gland is controlled.
Scratches on the inner surface of the copper bowl
Premium bottle closure supplier said that although the inner surface of the steel bowl is made of hard alloy steel which is relatively wear-resistant? However, after a period of use, scratches caused by friction will form on the surface in contact with the age cover.
The more scratches on the inner surface of the steel bowl, the deeper the damage, the more serious the damage to the bottle cap.
Premium bottle closure supplier said that these injuries are concentrated on the protruding teeth on the edge of the bottle cap.
Therefore, in production, if the length after capping exceeds the specified value, it is necessary to check the inner surface of the steel bowl.
