Classification

Classification Of UREXCEED Low Pressure Polyurethane Foaming Machine

UREXCEED^® low pressure pu foam machine is a device used in polyurethane foaming, casting, and other production processes, where raw materials are precisely mixed and injected under low pressure. It is widely used for small-batch production, precise control of the foaming process, and applications where the foaming speed is less critical. Compared to high-pressure foam machines, low pressure foaming machines are ideal for applications requiring gentler reactions or lower-density foams, such as flexible foams or low-density products.

The advantages of UREXCEED^® low pressure foam machines lie in their flexibility and energy efficiency, making them especially suitable for small-batch production or custom foaming products. They offer more stable control, allowing for precise adjustments when specific requirements for foaming rate, foam quality, or foam density are needed.

Working Principle Of UREXCEED Low Presssure PU Foaming Machine

The working principle of low-pressure pu foam machine involves precisely mixing raw materials and injecting them into molds under low pressure, typically used in polyurethane foaming, casting, and other production processes. Compared to high-pressure machines, low-pressure pu foaming machines are often used for applications that require gentler foaming reactions or lower pressures. The process is as follows:

01 Material Supply

UREXCEED^® low-pressure machine is equipped with multiple storage tanks for different raw materials, such as polyols, isocyanates, and other additives. These materials are delivered to the mixing head through pumps or pipelines.

02 Material Mixing

The low-pressure pump delivers each component to the mixing head at precise ratios and pressures. The materials are thoroughly mixed inside the mixing head to ensure uniform blending, resulting in a stable foaming process.

03 Low-Pressure Injection

After mixing, the material is injected into the mold under low pressure. Low-pressure injection helps minimize air bubbles and uneven mixing, making it ideal for applications where foaming speed is not as critical.

04 Curing and Molding

UREXCEED^® polyurethane material injected into the mold undergoes foaming and curing at low pressure. The curing time can be adjusted based on production requirements to ensure the desired product shape and performance.

FAQs

FAQs Of UREXCEED Low Pressure PU Foam Machine

Can a static mixing device be added to the low pressure pu foam machine?

Yes, a static mixer is a device that continuously mixes fluid materials without moving parts. Typically the fluids to be mixed are liquids, but static mixers can also be used to mix gas streams, disperse gases into liquids, or mix immiscible liquids. The energy required for mixing comes from the pressure loss as the fluid flows through the static mixer. One design of static mixer is the plate mixer, another common equipment type consisting of mixer elements contained in a cylindrical or square housing.

Does the pu low-pressure foaming machine need to add a fan to dissipate heat from the host?

It can be increased, but it is recommended not to add it because it is easy for dust to enter, and electronic components can work at a temperature of 90-120 degrees.

Is the low pressure pu foaming machine suitable for mass production?

Yes, low-pressure pu foaming machines are ideal for large-scale production, especially in cost-sensitive applications that require high throughput. They can provide stable production efficiency and are suitable for continuous production.

What is the production efficiency of polyurethane low-pressure foaming machine?

PU low-pressure foaming machines can usually handle a larger amount of raw materials in each foaming process and have higher production efficiency. The specific output of the equipment depends on the machine configuration and production conditions.

Is the operation of a low-pressure foaming machine complicated?

The operation of the low-pressure pu foaming machine is relatively simple and suitable for beginners and ordinary operators. Most equipment is equipped with automated control systems, making operation more intuitive and reducing the possibility of human error.

How to adjust the density of foam?

The density adjustment is mainly controlled by changing the proportion of components A and B. Low-pressure pu foaming machines are usually equipped with proportional control systems to ensure that foams of different densities can be accurately produced.

What are the maintenance requirements for the equipment?

The maintenance requirements of low-pressure pu foaming machines are relatively simple. Major maintenance tasks include regular cleaning of sprinkler heads, pipes and seals. The machine’s lubrication system and transmission system require regular inspection and maintenance.

Does the pu low-pressure foaming machine support customization?

Yes, the pu low-pressure foaming machine can be customized according to customer needs, such as adding barrels of different capacities, spray guns or changing pipeline configurations to suit specific production needs.

What is the energy consumption of pu low pressure foaming machine?

Low-pressure pu foam machines have relatively low energy consumption and are suitable for mass production, but the specific energy consumption also depends on parameters such as temperature and pressure during the production process.

How to extend the service life of low pressure foaming machine?

Equipment service life can be extended through regular maintenance, cleaning and replacement of wearing parts. Ensuring that excessive pressure and temperature do not occur during operation are also important measures to protect equipment.
