Engineering Plastics Joining Techniques

Design screw bosses with care. While small boss diameters reduce the tenden-cy for sinks and/or voids because they have thin side walls, they may not pro-vide sufficient structural strength to withstand assembly hoop stress. See figure 5 for suggested boss Get price

Polymer Screw Extrusion

The screw design is frequently modular, which allows for a nearly unlimited number of possible screw con gurations. Kneading blocks comprise several discs staggered at an angle to one another, the motion of which causes intense shearing and has a chopping effect on the material stream. Get price

Compounding twin screw extruders

1-Introduction This article aims at giving a 's eye view on PVC extrusion with particular emphasis on screw design. PVC compounds are extruded in single as well as in twin screw extruders. Whereas co rotating twin screws are mainly used for compounding operations, counter rotating screws are used for the extrusion of profiles, tubes and rods. Get price
