Effect of decoration film on mold surface temperature during in-mold decoration injection molding process

International Communications in Heat and Mass Transfer, 2010
Abstract In-mold decoration (IMD) during injection molding is a relatively new injection molding technique and has been employed for plastic products to improve surface quality and achieving colorful surface design, etc. During IMD processing, the film is preformed as the shape of mold cavity and attached to one side of the mold wall (usually cavity ...

Parameters Affecting the Ink Wash-off in In-mold Decoration of Injection Molded Parts

International Polymer Processing, 2012
Abstract Ink wash-off has been one of the problems that has confounded the overall success of the in-mold decoration (IMD) process for injection molded parts. In this report, an experimental matrix design based on the Taguchi method was conducted to examine the influence of processing parameters on the ink washoff of molded parts.

Mechanism of Bubble Formation in a Combined In-Mold Decoration and Microcellular Foaming Injection Molding Process

Fibers and Polymers, 2019
A combined in-mold decoration and microcellular foaming injection molding process (IMD/Mucell) is proposed to improve the surface quality of foamed parts. Through theoretical inference, the mathematical models of temperature field, velocity profile and forces on bubble were established with combining traditional mathematical models and the different ...

Effects of insert film on asymmetric mold temperature and associated part warpage during in-mold decoration injection molding of PP parts

International Communications in Heat and Mass Transfer, 2013
Abstract In mold decoration (IMD) injection molding is a relatively new multi-process technique that has been used for improving the surface quality and achieving colorful cosmetic surface of molded parts. During IMD processing, the film having the same shape as mold cavity is first inserted into the mold then molten polymer is injected into the ...
