Precision Injection Molding PRECISION PROCESS CONTROL OF INJECTION MOLDING
1 INTRODUCTION The technical requirements of precision injection molded components demand a heightened level of process performance, and with corresponding process monitoring and control technologies. To obtain the desired critical to quality attributes (CTQs) of the molded products, the injection molding process must be consciously designed such that the key process variables (KPVs) are observ...
متن کاملCarbide Bonded Graphene Coating on Silicon Mold for Precision Glass Molding
The severe adhesion between silicon and glass has limited its application as mold material in precision glass molding. In this paper, a novel coating approach to create non-stick silicon mold for glass molding was introduced by using carbide-bonded graphene, a two dimensional material with a patterned atomic structure. A graphene coated silicon mold was fabricated using a coating process develo...
متن کاملStudy on the Mold Temperature Control for the Core Plate during Injection Molding Process
Abstract: During injection molding process, the mold temperature is one of the most important influences on the product quality. In this paper, the temperature of the core plate with the size of 100 mm × 100 m × 40 mm will be examined for different product sizes. Different types of heating and cooling channels are inserted in the core plate. The size of the plastic product will be changed from ...

متن کاملAnalysis of the Three Dimensional Mold-filling Process in Injection Molding
For the three decades, the mold-filling of injection molding process was modeled as Hele-Shaw model. However, this model can not consider the 3D effect. In this paper, numerical simulations of three dimensional mold-filling during the filling phase were performed. The governing equations were discretized by segregated finite element method, which used equal order interpolation for pressure and ...
