The history of three-piece can designs goes all the way back to the 1950's when the English began using what was called the "three-piece" can. Three-piece cans still exist and these days are popular for use as kitchen canisters. Three-piece designs still have their place in can design today and they're not as widely used as they were in the past. One of the most common three-piece designs is a one-gallon steel can that has a one inch tall opening. The top of the can may be stamped with the manufacturer's name or some other symbol. On either side of this design is a metal piece that's been cut into thirds and secured by welding.
The first modern can model probably had a welded side seam on both sides but over time this has nearly completely been replaced by a three-piece can with a welded bottom seam. The first step in creating a three-piece can with a welded bottom is the shaping of the cylinder that forms the body. A metal file is used to remove any excess metal from around the edges of the body and a welding machine is used to burn a hole through the top of the can in order to create a three-pronged "eye" so that the side and bottom pieces can join together. This is typically a single-bladed tool with a very narrow tip which is used to weld the two pieces of metal together. The inside of the eye is then smoothed with a grinding wheel but care must be taken not to damage the internal paint of the can.
Because a tinplate can is generally made from copper, tinplate is a great material to use for a three-piece design. Tinplate is a good choice because it is very easy to shape into the desired configuration and also because it does not conduct heat well. It is important to keep in mind that while a tinplate body looks good, it may be difficult to actually get a good seal with tinplate because the tinplate body is rather thin and can easily be damaged if too much heat is applied to the welding area. For this reason it is usually easier to work with a larger sheet metal such as stainless steel. Working with stainless steel means that there is more flexibility when it comes to the possible configurations of the joints.
Using tinplate allows the individual pieces of metal to be joined at any angle which makes it much easier to create intricate shapes. When using tinplate the jointing amperage should be increased slightly so that the amount of heat applied to the area is reduced. The amount of solder used will depend on what type of tinplate is being used. If you are using low alloy grade tinplate then it will require more solder to ensure that it is thoroughly welded. Welding a two-part tin plate requires eighteen percent less flux than welding a one-part piece of tinplate. This is because a larger amount of filler wire is needed to complete the arc and it adds to the difficulty of the weld.
The Three-Piece canbody production lines are an essential part of many large production facilities. They help to produce thousands of cans every hour. There are numerous applications for these types of equipment. Candy industry can be easily started in a small factory by making cans from raw sugar. Other industries that make extensive use of this equipment include medical, photographic and food processing industries. Most of these canbody production lines are operated manually because they are very time consuming to operate.
Many businesses choose to use automation to operate these types of machines so that the operator need only have a computer terminal and a monitor. Automation makes it possible to speed up the process without losing quality of the product. If you want to know more about Three-Piece cans, feel free to visit my website by following the links below.
