Autodesk Moldflow is a simulation package for plastic injection molding. As part of the solutions for Digital prototyping, it helps CAE analysts and manufacturers optimize the design of plastic parts and injection molds. In general, models of the plastic parts are created at the first stage of product optimization and the major concern is the manufactured quality of the parts. Once the product ...

This paper describes algorithms for automated design of rotary-platen type of multi-shot molds for manufacturing multi-material objects. The approach behind our algorithms works in the following manner. First, we classify the given multi-material object into several basic types based on the relationships among different components in the object. For every basic type, we find a molding sequence ...

This paper deals with design method for structure of injection mold fabricated by Metal Laser Sintering, which is one of the rapid prototyping technologies. This technology provides mold with more sophisticated function and improvement of formability and productivity. To realize structure of mold with these advantages, the method has been developed by following processes : (1)Specifying importa...

Abstract In this paper, injection molding is used as a method of plastic molding, which in the molten state injected into closed mold cavity by compression, and material fills then cured cooling to maintain shape mold. The basic structural form parameters mold’s parting surface, winding system, system are determined flow analysis. CAE analysis move filling computer, casting system’s design sche...

The air-gap nucleation time, the stress evolution and the solid shell growth pattern are examined for different mold topographies to illustrate the potential control of aluminum cast surface morphologies during the early stages of solidification using proper design of mold topographies. The interaction between heat transfer and deformation during the early stages of solidification is considered...

The quantity of plastic parts in mechanical and electronic industry during past 2-3 decades has a tendency to grow up. Mechatronics systems, in particular, apply many parts of plastic materials. A plastic, which is one of the most versatile materials in the modern age, is widely used because this is an easiest way to get parts of complicated geometrical form and properties. The injection moldin...

Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and thei...

This paper describes activities relating to mold level control in continuous casting process as case examples of our process control solution business, in which we clarify and evaluate the process phenomena and design the control system. Initially, a mold level control model has been formulated by fluid flow analysis technique that evaluates molten steel flow in the mold quantitatively. The mod...
