Information

High pressure Polyurethane foaming machine is the most popular machine in Polyurethane foaming industry.

high pressure Polyurethane foaming machine can be tailored to:

Connect with 8 mix heads, for stationary molding applications
Become the pouring station for continuous process line
Permit more components for colored foam, dual density foam or multiple products system
EMM series outputs are available ranging from as low as 40g/s to as high as 500g/s, at ratios ranging from 1:5 to 5:1

We offer EMM series machine in the same quality as the European. But in order to help our customer starting a new project, we design the low configuration foaming machines as your requirements for very low price. And all EMM meet today’s stringent demands for chemical processing and plenty of spare parts in store.
Detail

In the polyurethane industry, EMM machine is a process where two reactants, typically isocyanate (iso) and polyol are pumped under high pressure into a high pressure mixing head. Inside the mixing head the iso and polyol collide at extreme velocities inside the mixing chamber, this is referred to as impingent mixing. The resulting high speed collision creates turbulence inside the mixing chamber, this turbulence mixes the reactants. The mixed reacting fluid exits the mixing head and enters the mold.

Advantages:


1. Multiple choices,machine can be chosen according to the configuration.

2. Easy to maintain, customer can designate spare part brand in local market.

3. Easy to operate.

4. Rich vulnerable parts in stock.

5. Professional After-sale service: Remote guide through computer and engineers install the machines on customer's site.

6. Professional manufacturer: We only manufacture PU forming machines and production lines, no other machines.

Mixing Head Principle:


The reactants collide at extreme velocities inside the mixing chamber. This is referred to as impingement mixing. The resulting high speed collision creates turbulence inside the mixing chamber, this turbulence mixes the reactants. The mixed reacting fluid exits the mixing head and enters the mold. Mixing heads are the key elements of Polyurethane production system, they determine the cost-effectiveness and quality of Polyurethane processing.

Item 2: Metering pump units


Meter pump unit is composed of an AC motor, magnetic coupling, metering pump with relief valve, flow meter, high pressure sensor, low pressure sensor, air release valve and Gap-Type Filter.

The magnetic coupling is a device for to transmit a torque between AC motor and metering pump without mechanical contact.

Brand & quality: METAU Italy or Chinese

Motiiv:

*No leakage forever, cause a cup seal on pump side
*No maintenance, cause no mechanicalcontact
*Safety torque, the maximum torque is limited during design
*Less mechanical vibrations, cause magnetic action is a vibration damper

For reducing cost, we provide mechanical coupling. But the pump seal will lose efficacy even with lubrication.It’s just a matter of time.

Metering pump


*The metering pump is a special axial piston variable pump for polyurethane foaming field. It transport polyurethane component under precise stability flow and high pressure to mixing head
*Metering pumps are the key elements of Polyurethane production system, they determine the cost-effectiveness and quality of Polyurethane processing
*Flow change by motor speed or pump’s hand wheel
*Brand & quality: Rexroth A7VK&A2VK series, DUT DMP series, Rotary power C range, Chinese brand, other brand on required.

Motiiv:

1.High metering accuracy and repeatability of the variable flows
2.Manual control via handwheel with built-in-precision measuring scale or alternatively mechanical rod control, for mounting 3.pneumatic or hydraulic control cylinders (remote control)
4.Operating pressure up to 250 bar
5.Low suction pressure, even when pumping highly viscous fluids
6.Very little pulsation of flow
7.Compatibility of pump components with materials to be pumped through use of specially matched materials and special seals
8.Quiet operation
9.Optimum volumetric efficiency

Flow Meter


Principle: The medium drives the gears. A non-intrusive sensor detects the movement of the gear. As each tooth passes the sensor, the sensor produces a square-wave pulse and measures a discrete volume of liquid. The resulting pulse train is proportional to the actual flow rate, providing a highly accurate representation of the fluid flow. The flow meters are highly wear-resistant moving parts to provide exceptionally long service life.

Flow meter is the key part for Closed-Loop Flow Control system.
