The Effect Of Liquid Hot Filling Temperature On Blow-Molded Hdpe Bottle Properties, Benjamin S. Hudson
The Effect Of Liquid Hot Filling Temperature On Blow-Molded Hdpe Bottle Properties, Benjamin S. Hudson
Theses and Dissertations
The occurrence of deformation in plastic bottles is a common problem in the bottling industry where bottles are blow molded, hot filled at high temperatures and sealed. Plastics have unique properties that make it difficult to predict when and why such changes may occur. The root cause of such deformation is unknown by many bottle producers and recent attempts have been made to minimize the occurrence of such defects. The purpose of this research is to determine which variables involved in the bottle production process influence bottle shape. Earlier variables that were tested included both blow molding resin and total …

Development Of A Particle Flow Test For Rotational Molding, Russell B. Whatcott
Theses and Dissertations
One of the current testing method (the Dry Flow test) to qualify resin for use in production in the rotomolding process has been shown to have many flaws in both equipment and procedure. Research was done here to investigate a possible alternative that could eliminate some of these testing deficiencies. By reducing equipment and operator errors, the testing of materials becomes more valuable of an exercise. The Angular Flow test developed in this research can increase repeatability. By coming to understand the rotational molding process better, an evaluation that can give more valid information was devised.
