6.2 Assembly and functional tests
The glue used for textile covering and heel assem-
bly is fully compatible with ABS; its adhesion was
tested with optimal results regardless of orientation
and process parameters.
Regarding SH1, because of the incomplete dissolu-
tion of supports inside the hole, O1 B was impossible
to assemble with the spine and the top piece; thus this
configuration is to be considered not valid.
More issues were observed during the assembly on
the heeling machine: while O1A did not encounter any
complication, O2 A and O3 A samples broke down.
