Molds that trim their parts
Change the mold's gate, the small opening where plastic enters the part, so the part breaks off as the mold opens.
| Cost | $2,000 to 6,000 per mold, in the mold shop |
| Payback | Not counted |
| Limitation | It suits only some parts and plastics, and a customer may have to approve the mark it leaves. The first check shows how much of the hand work is cutting. |
