Development of In-mold Coating Process for Thermoplastics Injection Molding

Finding efficient frontier of process parameters for plastic injection molding

Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...

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...

Study 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 ...

Analysis 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 ...
