Efficient Heating in Vulcanization Molding Using a Mold

Design of Revolute Joints for In-Mold Assembly Using Insert Molding.

Creating highly articulated miniature structures requires assembling a large number of small parts. This is a very challenging task and increases cost of mechanical assemblies. Insert molding presents the possibility of creating a highly articulated structure in a single molding step. This can be accomplished by placing multiple metallic bearings in the mold and injecting plastic on top of them...

GroEL–Substrate Interactions Molding the Fold, or Folding the Mold?

(K d in the low micromolar range). As a first step, Chen and Sigler formed cocrystals of the SBP peptide and the isolated apical domain of GroEL (residues 191–336), and Molecular chaperones ensure that proteins achieve and solved this structure at high resolution (2.1 A ˚ , see Figure maintain their proper folds in the appropriate cellular 2a). They have also solved and partially refined a stru...

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 ...

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 ...
