I have a question on overmolding a new part. The scenario is as
follows: We will be injection molding pvc, 50 durometer from alpha
gary, onto a radel or ultem insert. We make the radel/ultem inserts
in our machine shop. Our product folks would like to use a primer to
ensure cohesive bonding of the pvc to the radel/ultem inserts. They
would like to treat the radel/ultem inserts prior to molding. The inserts
have mechanical locking features machined into them already. Does anyone
know of an acceptable primer to apply to get a good bond between the pvc
and radel/ultem inserts? Thanks.
