Step 7: Cut Off

Once the shell material has been removed, the parts are cut off the sprue and the gates are ground off. Part cut off can be done manually:

• Chop saw
• Torch
• Laser (limited applications)

Parts can also be cut off using automation, that is, the mold can be secured using a fixture on a programmable cut off saw.
