There are many manufacturers of Kaiping machines, and it would be difficult for those who are not in this industry to choose. Two years ago, there were only a few manufacturers promoting Kaiping machines on Baidu. Now, through Baidu search, I have found many new manufacturers, but I have not found a few really good Kaiping machine manufacturers doing Baidu promotion. When choosing a Kaiping machine manufacturer, you should know:1. A manufacturer who truly produces a good product does not need to promote it on Baidu, as there are already too many orders from professional manufacturers to fulfill.When browsing the company website, check their product business scope. If their business scope is diverse, then the company is likely not a professional longitudinal cutting machine manufacturer.3. It is better to wait for a longer time than to order from a professional manufacturer. Choose an unprofessional Kaiping machine manufacturer. Although the price is low, the unreliable quality of the equipment will bring you a lot of waste, and the cost will be even higher when calculated.Before choosing a manufacturer, it is important to observe the operation of the equipment manufactured by the factory and conduct on-site inspections to understand user feedback.5. Search for keywords such as "Kaiping machine", "Kaiping line", "Wave shear machine", and "Wave shear line" on the internet to learn about the quality of the manufacturer's products.The materials with a thickness of 0.1MM-0.5MM for tinplate, cold-rolled plate, and aluminum plate are first-class equipment. The materials with a thickness of 0.5MM-1.2MM for tinplate, cold-rolled plate, and aluminum plate are first-class equipment. The materials with a thickness of 1.2MM-2.0MM for tinplate, cold-rolled plate, and aluminum plate are first-class equipment. The materials with a thickness of 2.0MM-3.0MM for tinplate, cold-rolled plate, and aluminum plate are first-class equipment. These equipment can also process color coated and galvanized plates. The others are equipment above 3.0 millimeters, including hot-rolled coil leveling equipment. As for where to do the best, it's difficult to determine, it's up to you to find out for yourself.
