Special-shaped aluminum cup and production method thereof

Abstract

The invention discloses a special-shaped aluminum cup and a production method thereof. The special-shaped aluminum cup sequentially comprises a cup bottom, a concave cup body, a convex cup body and a concave cup opening from bottom to top, wherein a curled edge is arranged on the concave cup opening, and all the parts are integrated. According to the special-shaped aluminum cup and the production method thereof, the diversification requirement of product modeling can be met, and the appearance printing design of products can be completely retained, so that the attractive power of the products are guaranteed.

Description

Technical field [0001] The invention relates to a special-shaped aluminum cup and a production method thereof. Background technique [0002] At present, the common aluminum cups on the market have a single shape. They are all straight cylindrical or tapered (large upper mouth, small lower mouth), or spun-shaped trumpets, which are in front of the increasingly abundant life needs. Each has its shortcomings. The straight-tube type has a simple appearance and can only maintain the same diameter at the bottom and mouth; the tapered aluminum cup is similar to the straight-tube type, but the bottom diameter will be smaller than the mouth diameter, and the cup body will remain straight; straight and tapered The only advantage of the flared cup with spinning process is that the printing shape of the cup body can be designed and selected arbitrarily, because it is straight and not limited by the printing process; while the flared cup with spinning process can be basically shaped. It con...

Problems solved by technology

[0002] At present, the common aluminum cups on the market have a single shape, all of which are cylindrical or tapered (large upper mouth and small lower mouth) by drawing and processing, or trumpet-shaped by spinning. Each has its own shortcomings

The appearance of the straight type is simple, and the bottom and the mouth can only maintain the same diameter; the tapered aluminum cup is similar to the straight type, but the diameter of the bottom will be smaller than the diameter of the mouth, and the cup body remains straight; straight and tapered The only advantage of the bell-shaped cups processed by spinning is that the printing shape of the cup body can be designed and selected arbitrarily, because it is a straight face without being limited by the printing process; while the bell-shaped cups processed by spinning can basically be used in shape. It fits the shape of a cup with a small bottom and a large mouth, but there are also obvious shortcomings: 1. The reprocessing of the surface of the cup body is affected by the surface curve and cannot be printed as a whole, but can only be limited to small areas such as partial printing in a small range Processing; 2. Due to the limitations of the spinning process, the diameter of the finished cup has been increasing during the process of extending from the bottom to the mouth of the spinning cup, and it is impossible to process a concave shape in the middle or a bulging cup in the middle. cup shape
