Transcript of Extrusion of Plastic Metal Combinations - in One Go!
Extruding Plastic & Metal in One GoApplications and Manufacturing of Hybrid Extrusion Profiles
Traditional Co-Extrusion If one material doesn’t meet all technical
requirements, it is combined with another material to yield further functions
Usually soft and hard thermoplastics
However there are many applications which require the combination of plastics and metals,
e.g. cables, hinges, spoilers, frames, ...
Surface Coating A common solution is the coating of the core
material with thin layers, either sprayed or glued
Usually soft and hard thermoplastics
But what if the extruded thermoplastic profile needs to have a metallic look or provide metal properties?
Hybrid Extrusion Combining thermoplastics and metals during the
extrusion process is called ‘Hybrid Extrusion’
Hybrid Extrusion – Why? This new approach to material engineering has
made it much easier to provide materials with a cool touch
Chrome- or aluminum glance and combinations of stiff and soft properties
E.g. conductance, magnetic attraction, and stiffness - all of that in a cost effective way
Several new fields of application
Hybrid Extrusion – How?
1. One base layer – the thermoplastic, e.g. PVC, TPU, ABS
Granules fed into hopper, melted in screw path
2. Forcing of the material through a die & cooling it
3. Roll forming follows (different possibilities here, for details see the free whitepaper): apply even pressure This is the trickiest part which requires experience to
avoid surface damage
4. Cutting of the material
Hybrid Extrusion – Avoid mistakes
It is important to consider a couple of factors before getting started: Design: Can extrusion do the job? Material: Which materials are suited? Processing: Which die architecture makes sense? Line design Process & quality control
