At present, the three-piece cans and the two-piece cans are not much developed in terms of technological level. They are only some improvements, welding is also good, and the two-piece cans are also good at drawing and pulling, and the process needs to be further improved. There are basically no other big differences. The new product aluminum film lid can be said to be a relatively new product. It was previously used at Nestlé. Now that it has passed the time of patent protection, it has begun to be widely used in the market. Its greatest advantage is its safety. It is not easy to scratch the fingers. Although the aluminum film is not as tight as the lid, it is basically harmless to people. It is the most widely used in dry goods, such as tearing in the uniform food. Cover and aluminum easy to pull cover. However, there are still many difficulties in applying aluminum foil lids to other areas, such as meat.
Due to the technical problems of the aluminum film easy to pull the lid on the curling, there are still some defects. During the production and use, we must pay attention to the protection of the edge. Our company is also studying many methods. The first method is too difficult. There are many costs, so we are now studying another method. There is no problem with dry goods, and other new products also need improvement. At the show we have seen things that are already old. In Europe and America, this method has already begun to use, but we The price of tinplate is high, but the price of cans cannot follow up and it only starts to save costs.
The secondary cold rolled iron Origian is one of the most advanced in the industry. Once the time is right, the secondary cold rolled iron is at the forefront in the application of the current production line, and the utilization rate of iron is also relatively high. In the case of double stripping and shearing, the utilization rate can be greatly improved. At the same time, our company also conducted experiments on powders. The key is the issue of powder quantification.
People who are now optimistic about the Chinese market have increased more than two years ago. For Origen and other manufacturers, I hope my introduction to new technologies can help!
