Advanced PU Foam Machines for Cold Chain
The cold chain industry involves a lot of product applications, including refrigerated trucks, cold storage panels, cake cabinets, kitchen refrigerators, beverage cabinets, wine cabinets, cigar cabinets, insulation boxes, turnover boxes, etc. The production of these cold chain products is inseparable from polyurethane foaming machines.
UREXCEED polyurethane foaming machines have diversified configurations and high efficiency, support multi-point injection, PLC control systems, and meet the needs of medium and large cold chain products manufacturers.
The Types of UREXCEED PU Foam Machines
There are two main types of polyurethane foaming machines for producing cold chain products, high pressure PU machines and low pressure PU foam machines. High pressure polyurethane machines can be divided into ordinary high pressure polyurethane foam machines and cyclopentane system high pressure pu foaming machines. You can choose different models based on your budget, site size and output.
High Pressure PU Machine
UREXCEED high pressure PU foaming machine adopts high-pressure airless mixing technology. The two liquid materials A(polyol) and B(isocyanate) are transported to the mixing head through a high-pressure metering pump. Under the impact of high pressure, they are instantly mixed and evenly sprayed out for foaming reaction.

Cyclopentane High Pressure Polyurethane Molding Machine
Cyclopentane high pressure polyurethane injection molding machine is a kind of high pressure polyurethane foam equipment specially used for using cyclopentane as foaming agent. It adds explosion-proof system and safety interlock control system on the basis of ordinary high pressure pu foaming machine, and is used to replace Freon foaming agent, which meets environmental protection requirements (such as the Montreal Protocol).
★The injection mixing head can move freely in six directions: front, back, left, right, up and down;
★The mixing head adopts dual proximity switch control to achieve precise injection;
★The inverter soft start and high and low frequency automatic switching are low-carbon, energy-saving and environmentally friendly, and energy consumption is greatly reduced.

Low Pressure Polyurethane Machinery
Polyurethane Low Pressure Foaming Machine is also a device used for polyurethane foam molding. Compared with high pressure PU machines, it adopts mechanical stirring and mixing. The equipment structure is relatively simple and the cost is low. It is mainly used for small and medium-scale production or application scenarios that do not require extreme foam fineness.
The low pressure polyurethane foam machine uses a low pressure gear pump to transport the two components A/B (usually polyol and isocyanate) to the mixing head in a set ratio. The mixing impeller in the mixing head mixes them and then sprays them out. The materials foam and solidify on the surface of the mold or workpiece.

They work on different principles. One relies on high pressure to mix raw materials, and the other relies on mechanical stirring to mix raw materials. The high-pressure machine mixes more fully, has a wider flow range, and has a self-cleaning function. The low-pressure machine is smaller in size and cheaper in price, and can be used to produce some particularly small foam products.
The weight of the product you need to produce, the product output, your budget and the size of the site, etc.
