OEM price beer crown caps 27mm with environment protection PE liner

Short Description:

Although the beer bottle cap is only a very humble small lid, but it plays a very important role, with such functions as preservation, sealing, so, do you know how the beer bottle cap is produced?

The beer bottle cap is produced by the capping machine, which is composed of bottle turntable, capping head, capping slide, height adjustment device, hopper, blanking trough and so on. Beer bottle cap production process: cap feeding – positioning – cap pressing – reset .

The cap defines not only the diameter of the bottle neck, but also the shape of the edge of the cap and the material it is made of. The cap is required to be well sealed, which means more pleats; The cap also needs to be strong, which means there shouldn’t be too many pleats to ensure that each pleat has a larger surface area. However, the rusting problem in the production process of beer bottle cap is a big problem that troubles manufacturers. It can be done to prevent beer bottle cap rusting :

Control the quality of bottle cap material plate
In the beer production process to reduce the damage to the bottle cap rust layer.The punching cross section without anti-rust layer is caused by the limitations of the current inner cap processing technology, which is not a good solution for beer manufacturers.But according to customer requirements, in the plate after punching the cross section coated with rust layer, and then stamping forming
In production, if the length exceeds the specified value, it is necessary to check the inner surface of the steel bowl. The surface of steel bowl can be used again after grinding.

Finally, we can collect the LIDS when we finish drinking the beer,

then turn them into a handmade craft!

Crown cover is a stamping type of tin cover, generally according to the actual need to usually choose 0.23mm thickness, T3 or T4 hardness, tin coating 1.1° / 2.8g/m2 of tin (SPTE) or chrome (TFS).The tinplate material shall meet the MR standard, and the imported iron shall meet the Japanese JISG3303 standard;Must have certain strength and hardness, and must have certain impact resistance.

These LIDS are manufactured in accordance with the internationally accepted German standard DIN6099 to ensure that all LIDS are the same.

The standard specifies not only the diameter of the bottleneck, but also the shape of the edge of the cap and the materials used to make it.

One of the requirements for a bottle cap is that it should be tight, which means more pleats;

The cap also needs to be strong, which means you can't have too many pleats to make sure each pleat has a larger surface area in contact.

Twenty-one teeth is the best compromise between these two requirements.

Twenty-one teeth has become the industry standard in modern times

Because beer contains carbon dioxide, there are two basic requirements for the bottle cap of beer, one is better sealing, the other is to have a certain degree of occlusity, which is usually said that the bottle cap should be firm.This means that the number of pleats per cap must be proportional to the contact area of the top to ensure that the contact area of each pleat can be larger. The corrugated outer seal provides both friction and ease of opening, and 21 teeth are the best choice to meet both requirements.

Only by having a comprehensive understanding of the printing and coating process and stamping process of crown cover, can we find out the reasons for each link and make corresponding adjustments when different quality defects appear, and the product quality can be guaranteed
