... especially important in panel molds. Aluminum molds often require steel or hardened pinch-off inserts to prevent coining of the parting line when some of the hard (high durometer) engineering thermoplastics are molded. The term pinch-off refers to a raised edge around the cavity in the mold that seals off...
