INJECTION MOLD WITH SURFACE COATING OF THE INNER SURFACE |
| 摘要 |
A blow mold for PET bottles has the inner surface which contacts the hot PET during the blowing operation, coated with a layer of ceramic material having a nanometric thickness, of which at least one thickness layer is AI2O3 and/or TiO2 deposited by ALD technique. Due to this technique, the PET preforms are subject to less friction during the contact with the interior of the mold. |
