Bottling and capping in this industry
Most foods and beverages are packed in bottles fitted with a metallic caps. Popular brands such as Coca cola, Pepsi, beers and other beverages have long be packed using metal sealed bottles. In addition, pharmaceutical products stored in the glass bottles also utilize the top covering to effectively seal the container.
Use of power press in making metallic bottle caps
Power press machine is part of a larger manufacturing unit made up of the die, the blank material and the accessories for feeding the material.
The press supplies a heavy force to the punch which squeezes against the die and workspace to produce the desired shape. Punches and dies are replicas of the product to be made.
Metallic bottle tops are inherently made by punching using the power press. A flat sheet steel materials is specially printed to match the brand be packed. Normally, one sheet will have 24 to 48 prints. The sheet is then passed to the device.
The device rotational motion is converted to reciprocating motion that pushes the punch against the die. This effectively forms the shape and also shears it off from the sheet. In one process, up to 48 products can be pressed and formed. Due to the rapid cyclic movement of the machine, very many bottle tops are made with a minute.
In addition, the machine is also used to develop lids used to cover and seal many packed foods. These lids have special formations which can be produced by punches and dies.
Critical parameters that must be achieved
Though there are different types of this machine, the most common are the Gap frame and straight side types. The Gap frame assumes a C shaped structure where the dies are put. Since there sides are open, the die can be accessed from three sides. This machine handle high loads (250 tons) and is less costly
Since the backside is open, wastes and scrap can be easily discarded and this makes it suitable for mass production of caps and other punched products.
The straight side type is widely used for inline mass production. It has two vertical arms on the sides. It has a strong housing on the top part that house the crankshaft. They have crankshaft and pulleys that change the type of motion.
Trends in utilization of metallic caps in the industry
With the increasing number of foods, cosmetics and pharmaceutical industry requiring metal and plastic caps, the market is expected to rise gradually in the next 5 years. The use of metallic caps is however facing stiff competition from the cheaper plastic that contributes to over 80% of all the closures. In 2013, the closures market accounted for US$ 40 billion and this is expected to rise to US$ 43Billion (5.3%). US market closures consist of 80.6 % plastics and 9.8% metals. However, with the negative environmental impacts associated with plastics, the metallic closures are expected to take a larger portion.

Contractors specializing in fabrication of many custom items have to make numerous rings that differ in design. This is achieved by using CNC machine. The jewels are automatically made by adjusting the tools and feed. In addition, these devices have the capacity of not only performing the turning, facing and other conventional lathe work but can also mill and perform cylindrical grinding.
They are characterized by minute tool post and chuck which are designed to handle tiny work pieces. Their bed is machined to perfect straightness. They are also fitted with a plate chuck which assists in holding complex shaped work pieces. They have a smaller bed, tailstock, head stock and carriage. These machines also have low power consumption and are very efficient. They are compact, durable and have excellent functionality.
The shape of the container allows easy stacking on top of each other. Since they are manufactured from high strength materials and locked, they are intrusion free. They also have identification number allowing for easy tracking via GPS and RFID.
Aluminum types are made of steel frames while the sides, front, back, roof and bottom are made with high strength durable aluminum.
The roof panels are made pressing using a specially designed press brake machine. This device punch presses the plate against the die to form the intended shape.
The floor frame is then made by cutting the plate using a shearing machine and these are folded using a press brake machine. This machine folds the material forming a U shaped bracket. A series of these brackets are welded to form a very strong base.
Tractor engine (Inline and V type): numerous holes and attachments done with radial drill
Role of bending machines in fabrication of these systems
Special features
In 2012, the global AC market was valued at US$86.8 billion and US$91.6 billion in 2013. The Asia pacific region has the highest demand due to rising industrial, commercial and residential sectors. The main units demanded are roof tops, indoor packaged, chiller plants and central ducted types.
