COMPUPLAST presents the Amazing New Ultra Micro 3-layers Co-Ex film & sheet line

Featuring:
● Conical 8 mm extruders that can use regular pellet sizes
● Sectional feed block for A+B+A configuration
● Professional rolling stack with internal water heating and cooling
● Adjustable roll pressure
● Motorized wind up with bobbin gripper
● Touch screen control of all machine functions
● Up to 75 mm wide die with adjustable lips
 

The line feartures two units of our conical extruders which have the unique features to be able to use regular plastic pellet sizes. This is made possible by having an in feed section diameter of 18 mm which then gradually reduces to 8 mm at the screw tip.

The line features a section type of feed block which divided the in flow from the two extruders into layers A+B+A. This feed block type ensures a very even layer thickness. The layer thickness is regulated by the speed from the extruders which are driven by infinitely variable speed servo motors with a very constant RPM.
 

The flat die is of coat hanger type and has a set of adjustment screws for the lip gap. With this the gap can be set from 0.1 to 0.3mm

The feed block and die is connected to the extruders with C-Clamps. They can easily be removed for fast cleaning of both extruders as well as feed block and die.

Rolling stack with water heating and cooling

All tree rolls in the rolling stack are double walled for internal heating and cooling and connected to a built in water heating and cooling tank with circulating pump. The connections to the rolls are through miniature rotating joints.

The sub cabinet contains the custom built water circulating unit with which is connected to an external water supply. Due to the large internal water tank, the system can be used for several hours without the need for an external supply of cold water.
 

All the functions on the entire Ultra Micro Co-Ex Chill roll line are controlled on a touch screen with clear and easy to understand graphics. Shown here to the right is the main screen where the whole line is illustrated and where the running Parameters are clearly shown in real life.
 

The touch screen controller has a multitude of pages for easy and clear visualization of all machine functions

The sub cabinet also contains all the electrical and electronic components comprising of AC Servo & DC motor controls, relays and controls for water pump, electric water heating, PLC unit for touch screen and various safety controls.

The machine complies fully with CE and all other countries safety standards.
