Can Polycarbonate be Blow Molded?
(OP)
I have a customer that wants to injection mold a base then blow mold a sphere from it.
Can this be done in Polycarbonate?
I have extensive experience with injection molding of engineering grade resins but know nothing about blow molding.
Thanks in advance.

It can be injection blow or extrusion blow moulded.
As suggested, contact material suppliers. Also contact machinery suppliers.

You need the parison to have enough strength when melted to support it's own weight while being stretched by the blowing process.

Blow molding grade should have lower melt flow rate.
