Arc Lines PU

Line serves for pouring PU mixture to the open moulds Power 10 - 70 ml per sec. For larger forms is intended Arc Line ISO PU .

volume of containers is 250 l, are equipped with stirrers with electric motor
material hopper on the cover of each container is equipped by silica-gel air drying
cooling and heating by oil and circulatory pumps
indicating of oil level increase
heating of oil by electric convector, cooling by cooling unit with closed circuit
continuous level indication of each component on the main control panel and touch LCD display
each container is equipped with pump for filling of containers from barrels
heated suction pipeline for components

two accurate dosing gear pump with cycloidal gear box and electromotor
components are cleaned before entering the pumps, shell of filter is heated
pumps are heated
reading of component pressure with blocking of pump running during overrunning of maximal value

mixing head is fixed on the carrier, what is longitudinally moved on the arm
automatic longitudinal movement over the unit by pneumatic cylinder
automatic longitudinal movement of carrier with head over the unit
manual, crosswise movement of arm on the arc frame of form carrier
after pressing START button on the head carrier is position during pouring automatically stabilized by brake of crosswise movement
position of head with respect to the axe of units is read by inductive sensors
position, in which the unit is situated, is displayed on the touch LCD display

is constructed for two PUR components, with the possibility of supply of colour concentrate
coloring device"(container for colours)" cab be bought individually, see accesorries
inlet for rinsing by rinsing medium and blowing
mixing of both component is executed by rotary mixer with electromotor over the toothed belt
setting up of the accurate revolutions of mixer is displayed on the LCD display (RPM)
inlet and recycling pressure hoses are heated
mixing chamber is equipped with the cooling shell for water cooling from external aggregate

construction is made of 6, 12, 18 or 24 modular sections
unit for fixing of two-piece or three-piece moulds with the maximal volume W240xL420xH230mm
units opening and closing by the pneumatic cylinder with mechanical lock during closing- fully electric control for each unit
closing is two-hand after pouring is automatic or manual opening is automatic or manual
setting up of lean of unit with range ± 10°
each lower desk of unit is heated adjustable regulation always for 6 units

control of motors for container filling, of stirrers, of heating and cooling pumps and of dosing pumps
set up and regulation of temperature of heated hoses, of oil, of dosing pumps and filters
display of components temperature in containers for POLYOL and ISOCYANATE
setting up and control of unit temperature, common for 6 units
blocking of running during the deviation of actual temperature and set temperature
display of level of POLYOL and ISOCYANATE
blocking of running during shortage of one of component and during the rinsing
switch “holding operation” for saving of energy during shot-down of production
automatic switching off dosing pumps during overrun of maximal pressure
colour touch LCD display

setting up of desired flow rate of mixture from head (ml/s)
setting up of desired volume rate of ISOCYANATE to 100% of POLYOL
counter for cycles of pouring, rinsing, operating hour, number of product
setting up of doses for each unit individually (ml)
calculated time is automatically displayed from setting dose and discharge
setting up of time and of day in the week for automatic switching of heating the moulds (preheating before starting the production)
setting up of correct revolutions of head stirrer for pouring and individually for rinsing RPM
setting up of production batch for regular notice to the number of made products
setting up of time for looping the operation of stirrers of components in containers and pumps for oil
report “rinsing necessary” if the material stays in head without rinsing for longer time than is setting
possibility of prevention of change the important technical parameters by the help of password
operating report (“minimal level”, “air pressure decrease”, “temperature out of working range
breakdown report (“ circuit breaker breakdown”, failure phase”, “button error” ….)

switch / switch off of electromotor for head of stirrer
control of carrier brakes and arm
control of backsplash, pouring, rinsing and blowing
switch / switch off of the inlet of colour concentrate 1 and 2
touch monochrome LCD display for setting and control of the device state
function of “start” button placed in grip is automatically changed according the position of head

Change of technical parameters reserved

Air Drier Freezing – for totally dry air in press containers
Heating and cooling agregate – cool or heat of material in double tube (duplicated) containers
Cleaning PU – liquid cleaner hot for removing the PU material from metal elements
Containers for cleaning – suitable for use with cleaning PU
