Verfahren zum Abtrennen des Angusses von einem Spritzgießteil |
摘要 |
<p>In order to remove the sprue (5) from an injection moulding (1) such as a delicate recording-medium disk, e-g- a CD, without producing dust and without the need for complex mechanical operations, the invention proposes that most the hole (20) in the disc is produced by injection moulding and the rest of the hole by removing the sprue from the mounding by a laser (6) once the moulding has been taken out of the mould.</p> |
