The fiber-reinforced composite products with stiffness properties are usually superior to those of unreinforced polymer products. In recent years, fiber-reinforced thermoplastics have been a popular technology in the field of injection molding. A lot of automobile plastic parts are made by fiber-reinforced engineering plastic due to the superior mechanical properties and heat distortion temperature. Since the reinforced composites have anisotropic properties, the injection molding process of fiber-reinforced thermoplastics became more complicated. The thermal and mechanics properties of the composite strongly depend on the fiber orientation pattern. The property of the composite is stronger in the fiber orientation direction and weaker in the transverse direction. However, at the same time, the thermal shrinkage effect is larger in transverse direction and lower in fiber orientation direction. The molded product may have high internal stress and warpage at unexpected locations. Therefore, during the design phase of a new product, we must consider the processing details comprehensively to understand the fiber orientation and warpage behaviors.
| Injection molding is a very complex procedure that combines the mold design, part design, rheological material, and process condition. Firstly, the polymer melt flows through a delivery system consisting of a sprue, runners, and gates to individual cavities. The design of the delivery system, also called the runner system, is very important because of its large impact on the quality of molded parts and on the production cost. Once the cavities of the mold with the gate locations and the runner system are designed, the runner system must be balanced so that each cavity will be filled under the same pressure at the same time. When the melt flows into the cavity, it must have a proper process condition to control the part for ensuring the good quality. However, a conventional trial-and-error method is ineffective to predict and control the procedure because of the complexity of operation conditions from raw material to products. Therefore, selecting an appropriate operation condition is a critical point for effective injection molding. |
