The results over described use to all circumstance scientific studies and, for these good reasons, just the tool having a shoulder angle equivalent to 10° was considered for the following analyses.
Rising temperature and rising pressure can be observed with raising shoulder angle. The inclined surface area with the shoulder results in two helpful outcomes: over the just one hand, larger angles suggest a larger surface area and, therefore, larger heat enter; However, a conical shoulder floor encourages a cloth flow ingredient towards the center from the extrusion which enhances materials mixing and good bonding.
