    Abstract: A method for simulating a hydroforming process includes modeling a virtual hydroforming die and a virtual tubular workpiece. The virtual workpiece is placed within the die after the die has been expanded. The die is then contracted to a finished size while the workpiece is deformed into a non-circular cross section in contact with the virtual die. The workpiece is subsequently pressurized to simulate production of a finished part.

    Abstract: A method for determining compensated addendum and binder surfaces as part of a springback compensated stamping die for producing a stamped part includes modeling of the existing addendum surface and binder surface of the stamping die. The addendum and binder surfaces are modified according to a number of compensatory surface displacements and in-plane rotations required for springback compensation of the finished stamped part. Following this modification, the stamped part may be separated from the addendum and binder without a loss of dimensional accuracy.

    Abstract: A polyester composition containing: a) aluminum atoms; and b) alkaline earth atoms or alkali metal atoms or alkali compound residues such as lithium atoms; and c) particles comprising titanium, zirconium, vanadium, niobium, hafnium, tantalum, chromium, tungsten, molybdenum, iron, or nickel atoms or combinations thereof, where the particles improve the reheat rate of the polyester composition. The polyester polymer compositions may also contain phosphorus catalyst deactivators/stabilizers. The polyester compositions and the articles made from the compositions such as bottle preforms and stretch blow molded bottles have improved reheat rate while maintaining low haze, high L*, a b* below 3, and have low levels of acetaldehyde. In the process for making the polyester polymer, the polymer melt is polycondensed in the presence of a) and b), with the particles c) added in a melt phase process or added to the polymer in an injection molding machine or extruder. The polyester polymer composition can be made to high IV from the melt phase while avoiding solid state polymerization.
