Insulation Building Panel PU Foam Making Machine

PU Foam Machine For Insulation Building Panel

1. Profile:

JH60-type two-component high pressure injecting machine, low pressure foaming

machine, has one PLOY barrel and one ISO barrel, and the two metering units are drived

by two independence motors , through change the motor's speed to control the metering

pump’s output. This kind of machine is specially used in the polyurethane foaming

products.

2.7 Pressure limit and control system

Both Polyol and Isocyanate working pressure are in a range of 0~2Mpa. Whenever the

working pressure exceed the range, the machine will be stopped automatically and give an

alarm at the same time.

2.8 Component flow control and test unit

According with the pump’s flow,the components’ mixing range and the related parameters,Our machine can change the components’ flow out by adjust the shift motor. Testing andcorrecting the components’ flowing parameters and the mixing range by their own feeding valve, so as to adjust and control the components’ flow.

2.9 Mixing head:

Material inject to the mixing chamber through valve, with high precision. And no block.

l Using motor to drive the agitator mixing mechanical.

l In testing status, the motor and the shaft does’t run.

l The stirring’s advance and lag time are controlled by the electric, which can be option of the stirring model at Automatic and Manual two ways.

l The valves’ open and close is controlled by the pneumatic cylinder.

l The mixing head,mixing chamber and the nozzle are convenient to take down.

l Adjust the pressure balance by throttle valve

l By setting the “pouring”,flushing”,cleaning”,emergency-stop” at the control box.
