Extrusion Blow Molding - Processing
|
|
| Engineering blow moldings in PA, which are increasingly being used in both the automotive sector and other areas, are produced primarily from polyamide 6 and polyamide 66 products, and mostly in glass fiber reinforced grades. |
When these polyamides are processed by extrusion blow molding, it is particularly important for the material to have been very well pre-dried. The moisture content of the material affects both the stability of the parison and the surface quality of the blow moldings.
Furthermore, the plasticizing unit's design as well as the barrel temperature settings is of some importance.
When using Durethan for tanks and high-pressure storage systemsadditonal processing advice *has to be taken into account.
