Differences between Low Pressure Foam Making Machine and High Pressure Foam Dispensing Machine

Items High Pressure Machine Low Pressure Machine
Mixed approach High-pressure atomization collision mixing, strong mixing by the mixing chamber pressure of 8-12MPa The motor is stirred, and the mechanical and electrical mixing is used in the mixing head.
Exterior Precision production. General production.
Mixed effect The mixing effect is good, the foam quality is good, and the cells are stable and even. The mixing effect is general and the foam is uneven.
Environmental protection After pouring, there will be no residual material in the mixing head, the surrounding environment is relatively clean, the machine is self-cleaning, and no solvent is needed. Due to the large space inside the mixing chamber, residual materials will be left behind
Attrition rate No discharge head is required, no residual material is produced, and the foam quality is good, so the material usage is saved (about 5-10%) Due to the dynamic mixing, the mixing chamber needs to be filled before pouring the product, so there will be material residues, and the material usage is 5-10% more than the high pressure machine.
Convenience It is easy to operate and set the ratio. Computer input. The raw material tank is fully sealed. Material B (MDI) is not easy to crystallize. Use operation, set ratio, computer input, the raw material tank adopts atmospheric pressure circulation, prolonged shutdown can easily cause material B (MDI) to crystallize.
Independent color scheme Subject to mixing head technology, more than two colors are more difficult Support multi-color scheme
Environmental protection No environmental pollution. Low pressure machines have been banned in Europe (MC causes environmental pollution).
Mixing head life Simple maintenance, no need to clean the mixing mechanism, the service life is at least 1 million times The stirring should be changed frequently, and the mixing device should be cleaned every day.
Upgrade of cyclopentane system Support Not support
Filler Not support Support
Product application restrictions Products less than 20g are not recommended to use high pressure machine Products with less than 20g can be designed with micro foaming machine
Continuous injection Greater than or equal to 2 seconds. Greater than or equal to 0.3 seconds
Noise Low High
Price High Low
Foam quality High Low
Power High Low
Volume Big Small

Widely used in the production of heating floor tiles, refrigerator water tank insulation, water heater pipe insulation, insulation cup insulation box insulation and other products. Features 1. High-precision wear-resistant rotary valve device, simultaneous injection, long working life and easy maintenance; 2. High-precision measurement

  • 1.Are you factory or trading company?

    We are professional factory in PU industry with more than 10 years experience, covering high pressure pouring machine,low pressure foaming machine, pu spraying foam machine,pu elastomer casting machine and production line for flexible foam products like PU shoe /sole/insole,anti-fatigue mat, memory pillow, elastic stress ball, car seat and cushion,pu slow rebound ear plugs; also rigid foam products production line: PU decorative molding crown cornice line, float trowel making line, cold storage panel production line, sandwich panel production line, last not the least, elastomer product: forklift wheel casting line, coal sieve screen select line and so on.

    2.Where is your factory ?

    Our Factory is located in Wuxi city, Jiangsu Province.

    3.How can i get your factory?

    By air: You can take a plan to WUXI airport from China, if you fly from Korea ,Japan, USA, Singapore, Taiwan, Thailand you will can directly fly to us.

    By Train: You can stop at WUXI station, Not WUXI EAST station.

    4.Do you provide pick-up service?

    Yes, of course. If you are in Wuxi airport or station, we can arrange a special car to pick you up directly to our factory.

    5.What is the PU raw material used with this polyurethane/polyurea foam casting machine?

    Polyurethane which has two components polyol and isocyanate(poly and iso/mdi). Polyurea also can be used which helps to waterproofing and Anticorrosion and rust prevention. Polyurethane can be divided into two kinds, flexible foam and rigid foam. And flexible foam or rigid foam also has two kinds, open cell foam and closed cell foam.

    6.If I need to develop a special PU raw material formula solution based on my product, can you provide it?

    Yes, we can. We have technical team of chemical engineers and process engineers, all of whom have more than 20 years of experience in PU industry. We can independently develop raw material soluation like polyurethane rigid foam, polyurethane flexible foam, polyurethane integral skin foam and polyurea to meet customer’ s requirements.

    7.What is the application of PU foam machine?

    PU spray foaming machine has two functions:
    Spraying: building exterior wall coating, interior wall coating, roof spray, cold spray, cold storage spray, cabin coating, tank body coating, industrial anti corrosion, etc.
    Casting: solar water heater, insulation water tank, cabin, roller shutter door, security door, refrigerator, pipe joints, product packaging, highway construction, wall sound insulation, etc.

    PU polyurethane foam injeciton machine can make pu rigid foam products like pu crown molding, pu bed sets, pu plastering float, pu coldroom panel; pu flexible foam products like car seat cushion and car headsets, memory foam pillow, slow rebound ear plugs, pu stress ball and kids toy; pu elastomer products like forklift wheel, rollers, sieve screen and so on.

    You need to tell us specific machine application and budget, to spray or cast, then we can recommend suitable machine for you.

    8.How long is your polyurethane foam casting machine warranty?

    1 year. Within one yea, if it is not man-made damage, we will provide free replacement parts, but the shipping cost needs to be paied by the customer.

    9.How to solve the polyurethane foaming machine failure?

    For pu spraying machine: If there are quality problems with accessories during the one-year warranty period, we can provide replacement parts for free. If there are operations or other problems, you can send photos or videos to us, we will consult our engineers to help you solve the problem.

    For high/low pressure foam dispensing machine, elastomer casting machine and other production line: our machine all have remote maintenance and diagnosis function. You can also send us pictures or videos, our engineers can help to solve the problems via pictures and videos.

    10.What if I don’t install it after I get the polyurethane pouring machine? Do you offer installation services?

    Yes, we supply video technical support. If your company has engineer, you can come to our factory, we will provide field installation, commissioning and training. Of course, our engineers are available to service machinery overseas.

    11.What is your packaging of your PU foam injection machine?

    The normal package is wooden box (Size: L*W*H). If export to European countries, the wooden box will be fumigated. If container is too tighter, we will use PE film for packing or pack it according to customers special request.

    12.What transport methods do you have for your polyurethane foam making machine?

    For polyurethane foam spray machine, sea and air transportation are both available. For high/low pressure foam machine and other bigger machine, only sea transportation is accepted. But for little accessories of the machine like spray gun and mixing head, express is also ok.

    13.Can I be your agent in our own country?

    We already have some agents of pu spray machine, high/low pressure foam injection machine, pu elastomer casting machine around word like Pakistan, Iran, Malaysia, Algeria and so on, if you are interested, you can send your intentions with your company’s information and personal contact details, then we will email you our requirements to check if we can cooperate.
