Co-extruder
The co-extruder is an important part of the co-extrusion technology. It is specially developed to adapt to the small co-extrusion flow and can be docked with different forms of mainframe. In profile coextrusion, the extruder for extruding "small material" is generally referred to as a co-extruder, and the extrusion of the main profile is referred to as a main extruder. For co-extrusion of hard PVC profiles, the main extruder is usually a twin-screw extruder. The co-extruder is usually a single-screw extruder, and the small machine series are mostly type 25 and type 30.
The main purpose of the co-extruder is to work with a variety of main extruders, and it can also be used alone, with a suitable head to produce a variety of products.
The structural difference between the co-extruder and the ordinary extruder is mainly in the design of the frame. According to the different racks, the co-extruders can be divided into external and online. The external co-extruder can be divided into vertical, horizontal and angle co-extruders according to the installation position; the online co-extruder is placed on the main extruder and placed on the setting table. Minute. The co-extruder has the following characteristics:
1. Tight structure and small footprint;
2. Small control system, easy to operate;
3. Mobile rack for easy disassembly and assembly;
4. Flexible flow channel interface, strong versatility.
In the coextrusion technique, the arrangement of the extruder is also important. For new extrusion systems, if space permits, the extruder can be discharged side by side or star-shaped, and can be designed to be compact and easy to operate and maintain; for the existing extrusion system, the above arrangement can be used, or The coextruder was mounted shoulder-mounted on the main extruder.
In addition, Greiner recently developed post-coextrusion technology, which features a co-extrusion machine on the sizing table for composite co-extrusion after cooling and shaping the main profile.
