How are aluminum screw bottle caps made? This factory makes 250 million screw bottle caps of different sizes every year, consuming 1,000 tons of aluminum. Making screw caps starts with these pieces of aluminum.
First, the aluminum piece is first coated with a colorful glossy paint through an assembly machine, and after a 25-minute drying process, it is then printed on the surface of the aluminum piece with a design given to Jiangtong. Then the machine grabbed the aluminum sheet with sharp冒 and put them on the conveyor belt of the press hole machine, the press hole machine will press the aluminum sheet out of the shape of the bottle cap, this machine can press 500 bottle caps a minute, at this time the bottle cap has been shaped, but not the standard size. The next step is to carry out the second pressing of these bottle caps, after pressing the caps into the standard caliber with the milling machine, so that he can be perfectly combined with the interface. Equipment; cleaning equipment, injection molding machine, air compressor, vacuum plating equipment, stamping machine, screen printing machine, ultrasonic welding machine, hot stamping machine, spraying equipment, pad printing machine, mouth cup cap baking glue machine, baler, aluminum cap, then you have to corrode and polish and so on it! Some equipment have to do it themselves! For example, the assembly of the inner cover and the outer cover of the machine!
Second, the next to the customer requirements on the bottle cap for finishing, first to the bottle cap color, and then with a special ink through the steel roll decorative wear on the side of the bottle cap printed on the pattern, and then put the bottle cap in the oven for drying, drying the bottle cap will be detected by the machine, and will be pushed out of the bottle cap to fall to the side of the container, and then to make a cut in the molding of the bottle cap in the cutting and splicing machine of the perfect match, they can be a minute! With the perfect cooperation of cutting machine and joining machine, they can cut 200 caps per minute. Molds; injection molds, pad printing steel molds, corrosion molds, assembly molds, screen molds, stamping molds, etc., raw materials; (ABS resin, polyethylene and other plastic materials), aluminum tape, foam adhesive, cyclohexanone, ink, special paints, adhesive powder and so on.
Third, in order to ensure the watertightness of the solution inside the bottle, you also need to embed the same specifications for the bottle cap catch, so that the bottle cap can be tightly sealed the bottle mouth. Then check the bottle cap through the light to see if the cut grain and caoxian are qualified, and finally use the spiral reinforcement device to seal the bottle cap to the bottle mouth, so that an aluminum spiral bottle cap is manufactured.
