The development of the polyurethane high-pressure foaming machine industry in the industry can be described as rapid progress. This is obvious to all. I believe that its future development trend is also very good, so at this time, it's very necessary for learn more about the details of all aspects of the polyurethane high-pressure foaming machine equipment.
1. When the polyurethane high-pressure foaming machine is injected, the actual average density in the box cannot reach the theoretical density. This is caused by the uneven distribution of the density of the foam layer. The large displacement of the gun head will form the upper part of the box. Accumulation causes the density to be too large, while the small gun head displacement is just the opposite, which also causes uneven density distribution and affects the difference between the maximum and minimum density.
2. For the uneven density distribution caused by the displacement size, an approved minimum density must be established first. If the local area cannot reach the approved minimum density, the quality of the foam layer may be affected. Only by increasing the injection The amount of material to achieve the approved minimum density.
3. At the same time, the sealing performance of the box should be strengthened. The minimum density value of the domain, which can reduce the injection volume under the premise of ensuring quality.
4. The size of the row stars should be determined by the specific cabinet. For larger models (such as longer cabinets), the displacement of the secondary foaming machine gun head is slightly larger, while for smaller cabinets (such as Shorter box), the situation is just the opposite. In fact, on the production line, the cabinet models are diverse, and the gun head displacement is fixed.
With the help of cold storage polyurethane foaming machines, we have the opportunity to send out high-quality foam products. After market testing, the polyurethane foaming machine has many advantages, easy to use, and the foaming efficiency can also be improved. Learn more, use it in the right envir
