How cans are made
Cans for food, drinks and non-food products may be constructed out of either two or three pieces of metal.
The first cans ever produced were three-piece and they were developed in the middle of the 19th century. They consist of a cylindrical body rolled from a piece of flat metal with a longitudinal seam, usually formed by welding, with a top and bottom, each seamed on the ends of the body.
Three-piece cans may be manufactured in almost any practical combination of height, diameter and shape. This process is particularly suitable for making cans of different sizes as it is relatively simple to change the parameters of the can under production.
The Cazander Brothers mainly have machinery for three-piece cans in stock.
What is a score repair system?
A score repair system in canmaking refers to a system used to repair damages or scratches on the edges of metal cans. When metal sheets are formed and joined to make cans, small damages such as cracks or scratches can sometimes occur on the edges. These damages can compromise the integrity of the can and jeopardize the safety of its contents.
A score repair system utilizes special tools and techniques to repair these damages. This may include smoothing out the edges, removing sharp edges, or filling in small cracks. By carrying out these repairs, the structural integrity of the can is restored, reducing the likelihood of leakage or other issues. This contributes to the quality and safety of the end product.
