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.
Polyurethane high-pressure foaming machine is a special equipment for infusion and foaming of polyurethane foam. Polyurethane high-pressure foaming machines are essential in many production areas. Polyurethane high-pressure foaming machine is a kind of precision equipment. In the actual operation pr
High-pressure foaming machine, also known as foam generator, the product of the foaming machine is foam, and what we need in the production process is also foam. In the work, polyurethane foaming has to go through two stages of foaming and curing.The high-pressure foaming machine will present variou
As a common product, high-pressure foaming machine has widely appeared in our real life, and the development trend is increasing:1. Polyurethane products are made of isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retar
The high-pressure foaming machine works for a long time, it is easy to heat up too high, what are the ways to cool down?Today, I will talk to you about the temperature reduction of the high-pressure foaming machine.Large flow box type high pressure foaming machineWhen using a high-pressure foaming m
Because foaming relies on heat, if there is no heat, the foaming agent in the system cannot evaporate and foam plastic cannot be formed. The heat comes from two aspects, one is the heat produced by the chemical reaction, and the other is the heat provided by the environment. The heat of chemical rea
A considerable part of auto parts, especially interior parts, are polyurethane foam products.

Polyurethane foaming machine is a large-scale equipment, which is used in many production enterprises. The emergence of polyurethane foaming machine production line provides companies with a lot of convenience, and the performance of this equipment is also very good in all aspects. Many people are m
The high-pressure precision foaming machine is carefully designed by the designer according to the user, and there are many models of it. Users can choose the model that suits them according to their needs to purchase. The high-pressure precision foaming machine in the market is economical. It is ve
1. Raw material system. The pressure of the raw material tank should be dry air, and nitrogen should be used as much as possible. Before starting the machine every day, turn the turntable of the raw material filter to the left or right a few times, and remove 200~300ml of raw material from the botto
