Metal injection molding (MIM) is similar to plastic molding in many respects, but MIM compounds (metal powders with polymer binders) are more susceptible to thermally induced flow instability because of their higher thermal diffusivity. The flow patt

A three-dimensional transient finite element flow analysis code that includes inertia and free surface modeling is used to predict uniform (axisymmetric) and nonuniform (nonaxisymmetric) filling patterns in a thick-walled tool with a diaphragm gate.

A strategy has been developed for optimizing the design of runners in injection molds with multiple identical cavities. This approach is based on mathematically rigorous derivations using the power-law viscosity model under conditions where the press

Following the optimal runner sizing given in Part I, this paper establishes rules for runner layouts to minimize volume using a mathematical analysis. For four cavities with their centers forming a rectangle, the X layout gives the smallest runner vo

A novel processing concept, the directed flow die, has been demonstrated to be a powerful method for producing controlled curvature in extrusions with complex shapes. The directed flow die operates by changing flow path lengths between a single, rela

Publisher Summary This chapter discusses the use of nylon 6 in thin-wall housings for portable electronics. The semi-crystalline nature of nylon 6 results in an excellent balance of stiffness and impact along with good performances at elevated temper
