Laboratory Co-Extrusion Systems and Controls

 

The computer co-ex extruder controls can be incorporated on a central control panel, for instance when used for a co-extrusion line. Picture to the right shows the panel for a 3-layer co-ex film line and to the right on the screen are the three extruders shown. Here all parameters on extruders and downstream film blowing unit are controlled by touching respectively the symbol shown at the bottom of the screen.

 

5 Layer, (3)- 12.5mm Extruders Co-Ex Chill Roll Cast Film Line with PC Data Acquisition Program

The Conical Extruder screws are easily removed from rear of gearbox with out disassembly of machine.

The extruder screw has a diameter of 12.5 mm and length 30D. The diameter of
the in-feed section of the screw has been increased to 20 mm in order to allow
the feeding of regular sized pellets,

QUICK TIPS FOR PURGING PLASTIC

Chemically enabled Plastic Purging Compounds like XPD8 are heat activated.  To achieve optimum results, you must raise your heats in the areas that you know problems are likely to occur. Such as:    
Dies    
Areas of Negative Flow    
Sharp Angles in The Flow Path    
Blow Molding Heads

However, in areas that you feel you don't have a problem, do not deviate from normal heat profiles recommended
    
The Feeder Zone in Injection Molders    
Straight Screw and Barrel in Extrusion Systems

By following these guidelines, you will be assured that the chemical activity of the Purging Compound will be used where it is needed and not prematurely expended and wasted in areas where it is not necessary.


RBM suggests that every time you have a prolonged shutdown of your equipment to employ the amazing abilities of XPD8 High Performance Plastic Purging Compounds to give you worry free restarts time after time.

XPD8 Compounds will not freeze up your screws, will never plug up a die head, and will guarantee an easy start up after a prolonged shutdown without any problems at all.
