Publication number: 20090224431Abstract: A method of providing at least one heat sensitive material on at least part of a surface of a polymer article formed from a heated polymer whose temperature is sufficient to adversely affect the at least one heat sensitive material, wherein an at least partly textured shaping surface is provided. The heat sensitive material is applied to at least part of the shaping surface, the shaping surface being at a temperature at which the heat sensitive material is not adversely affected. The heated polymer is brought in contact with the shaping surface and formed by the surface shape of the shaping surface. The at least one heat sensitive material is transferred from the shaping surface to the polymer surface, while maintaining sufficiently low the temperature of the shaping surface so that the heat sensitive material is not substantially adversely affected by heat upon or after contact with the heated polymer.Type: ApplicationFiled: March 15, 2006Publication date: September 10, 2009Applicant: INMOLD BIOSYSTEMS A/SInventors: Niels Bent Larsen, Susan Blak Nyrup, Henrik Pranov

Publication number: 20090212464Abstract: The molding apparatus includes a cavity mold with a cavity surface for defining a cavity in which a molten injection material is injected, and a core mold with a core surface for defining the cavity upon engagement with the cavity mold. The core mold has an intermediate core mold plate having the core surface and a support plate. A guide pin inserted into a guide hole formed in the cavity mold and fitted through the intermediate core mold plate to allow the intermediate core mold plate to be moved only in a forward and backward direction is fixed to the support plate. A first spring is installed between the intermediate core mold plate and the support plate, a first heating means is installed to a parting surface of the intermediate core mold plate and a cooling means is installed to the support plate.Type: ApplicationFiled: May 8, 2009Publication date: August 27, 2009Inventor: MYUNG-HO KANG
