There are also many types of cold isostatic presses, different users in the choice of isostatic press requirements are different, for friends who are new to this piece will face problems in parameters, efficiency and other aspects, so to choose the right cold isostatic press we have to consider from many aspects, let's take a look. The selection of the volume size of the pressing cylinder: 1. The pressing cylinder of the cold isostatic press is a cylindrical container, and the selection of its charging diameter and height size is particularly critical; 2. The selection of the charging diameter should be considered: A. It must be larger than the size of the single pressed product blank (including mold); B. Due to the diameter size of the pressing cylinder, it has a great impact on the cost of the equipment, and it is necessary to comprehensively consider the placement form, quantity and production efficiency of the single-laminated blank (including mold) in the diameter direction; C. Consider the space of the compacted hanging rail. 3. The selection of charging height should be considered: A. It must be larger than the size of the single pressed product blank (including mold); B. Due to the limited impact on the cost of equipment due to the comparison between the height and diameter of the pressing cylinder, the number of layers and production efficiency of the compacted (including mold) placement are mainly considered; C. Whether the height space of the plant meets the lifting requirements of the hanging rail; D. Select the pit or ground installation method. Second, the selection of working pressure: 1. The working pressure has a great impact on the cost of the equipment, and the pressure selection is too high, which is easy to cause high production costs, low relative production efficiency and increased investment 2. Determine the working pressure of the required pressed products; It can be determined by experiment or adopt mature process technology 3. The working pressure of the selected equipment should be 20~50MPa higher than the working pressure of the product; 4. When the size and working pressure of a variety of products differ greatly, it is more appropriate to consider choosing equipment of different specifications. Third, to meet the requirements of the pressing process: 1. Products of different materials have different pressing process (pressure-time curve) requirements; The equipment needs to have the function of satisfying its corresponding process; 2. With the development of technology, the current cold isostatic press equipment can meet the following pressing process requirements: A. Standard pressing curve B. Standard proportional pressure relief curve C. Variable speed boost - whole process proportional pressure relief curve 3. When selecting equipment, enterprise technicians should communicate with manufacturers to ensure the process and efficiency. Fourth, the consideration of maintenance costs: 1. Single media structure, with the same specifications, the charging space is large, but the maintenance cost is high in use, and the maintenance personnel are high; 2. Double media structure, with the same specification, the charging space is small, but the maintenance cost is low in use; 3. If you press high-hardness materials such as ceramics, metallurgy, and refractory materials, and the maintenance strength is poor, you should try to choose a dual-media structure. Fifth, consider the ratio of investment to output.
