Default Structural steel plus plastic technique called ? failure mechanism?

VCR chews tapes because suspension arc for the jockey-wheel/idler/ slip
clutch assembly is an arc of plastic moulded over the steel of the chassis.
Then has cracked and catches the carrier as it swings across . A web of
plastic filaments joining odd bits of plastic pillars etc, located by
flowing through holes in the metal at formation, but one of the
interconnects forming this arc. If anyone remembers all those Philips car
radios that used plastic rim to the metal capstans, that failed, because of
excess heat inside the dashboard of a car in summer and differential
expansion of incompatible materials. Or I thought so ,this in a domestic
TV/VCR combo with ps and heat over the VCR , not under. This is a Daewoo
GB14F8T2 using coincidentally? lots of Philips chippery. So could it be just
an age effect, 1999 vcr, this hard plastic contracting with age
