摘要:
Various embodiments of the present invention generally relate to a light-cure and dual-cure resin that have low color and is color stable over conventional light, self and dual-cured resins. Additionally, the light-cure resin has enhanced degree of cure over conventional light-cure resins. Finally, due to the low color and enhanced color stability of the dual-cure resins, their inherent property of having lower shrinkage stress as compared to light-cure resins can now be utilized in various dental applications and other resin applications.
摘要:
A method for forming an automotive instrument panel having a concealed door comprising a series of steps. A plastic parison is extruded to form the substrate layer of the instrument panel. The parison has first and second walls. The parison is placed within a mold and the first wall is contacted with the second wall to form a hinge. The area of contact forms a bond between the first and second walls. A different portion of the first and second walls are contacted to form an opening path. The opening path intersects the hinge. The opening path usually has a thickness much less than the thickness of the first and second walls to form an easily fracturable area. The door swings on the hinge to open. A elongated section of material on the second wall, enables the second wall to wrap along the hinge when the door is opened.
