luminum slugs are metal disks that are impact extruded to make extruded aerosol cans, automotive cans, aluminum collapsible tubes and more. Aluminum Slugs are widely used in making electric container, cosmetic packing, bottle closure, capacitor shell, auto parts used in cold extrusion or deep drawing. Aluminum slugs have many specifications such as with holes and without hole, square shape and round shape.

How does the aluminum slugs made of? It has sevrial types. Punched from coils, strips or extruded plates. Sawn from round bars, tubes or profiles. The forms of aluminum slugs include round, oval, hexagonal, square, flat, domed and preformed. Today, we are going to talk about the bottle closure aluminum slug.

aluminum slug for bottle caps,Aluminium Circle

At present, the liquor, the wine and the medicinal liquor’s bottle cover are mostly made with aluminum slug

. This is because grass bottles are used in these fields. By using hot forming process, there are large errors in the aperture size. But using can achieve the relatively high seal. In the terms of the raw material, the cost of aluminum is lower than the plastic (an aluminum cap cost the half of an plastic cap), and anti-thef cap’s structure is very complicated, the current production lines in wine industry are designed for installing aluminum caps. What’s more, the aluminum anti-thef cap is finished with high-quality aluminum alloy. It has superior performance, and can be mechanized, mass production, and no pollution, and can achieve 100% recycling, and also can meet special requirements such as high-temperature steam sterilization. In addition, aluminum cap tend to replace the cork because of the unnecessary of special open tool, and it has got many bottle cap manufacturers' favor.
