Researchers have been working for 10 years on various aspects of injection molding, treated separately: material properties, fluid flow, heat transfer, machine characteristics, plastic part design, etc. They will integrate these various aspects to include the computer-aided design of plastic parts, and to cover computer control of the process. They will extend their activities to include injection molding of materials other than pure thermoplastics, e.g., thermosets and fiber-filled composites. Researchers will test packages applicable to the design of plastic parts, test and evaluate existing geometric molding systems in terms of their modeling capability for constructing a part and the tooling needed to produce the part, formulate techniques for adaptively controlling the molding process, and develop the software to integrate a complete CAD/CAM system for plastic parts. They will study flow of molten plastics through openings of various sizes and shapes in molds; determine how thermoplastics pack, cool, and shrink in molds; investigate the mechanical properties of molded parts as they are affected by alternative mold-design configurations and processing conditions; and simulate and investigate the injection molding of thermosetting plastics and polymers containing fillers such as glass fibers.

研究人员已经在注塑成型的各个方面工作了10年，分别处理：材料特性、流体流动、热传递、机器特性、塑料部件设计等。他们将整合这些不同方面，包括塑料部件的计算机辅助设计，并涵盖过程的计算机控制。他们将扩大其活动范围，包括注塑纯热塑性塑料以外的材料，例如热固性塑料和纤维填充复合材料。研究人员将测试适用于塑料部件设计的软件包，测试和评估现有几何造型系统对构建部件和生产部件所需工具的建模能力，制定自适应控制成型过程的技术，并开发软件以集成完整的塑料部件CAD/CAM系统。他们将研究熔融塑料在模具中不同大小和形状的开口中的流动；确定热塑性塑料如何在模具中包装、冷却和收缩；调查注塑零件的机械性能，因为它们受到不同的模具设计配置和工艺条件的影响；以及模拟和研究热固性塑料和含有玻璃纤维等填充物的聚合物的注射成型。
