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 study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injec...

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...

Thermoformed plastic parts are pervasive in modern products. Decorating these thermoformed parts is a critical step in their manufacture. For parts with significant relief, decorating the part after it is formed can be prohibitively expensive. Prior to thermoforming, the plastic which is in flat sheets or rolls can easily be fed through a printer. However, during thermoforming the plastic flows...

Designing cooling channels for the thermoplastic injection process is a very important step in mold design. A conformal cooling channel can significantly improve the efficiency and the quality of production in plastic injection molding. This paper introduces an approach to generate spiral channels for conformal cooling. The cooling channels designed by our algorithms has very simple connectivit...

One of the major challenges associated with the in-mold assembly processes at the mesoscale is the interaction between the polymer melt and the premolded components that are present in the mold. When a high speed, high temperature second stage melt comes in contact with a premolded mesoscale component having similar melting temperatures, the premolded component undergoes thermal softening and p...

The development of many photonic devices, such as photonic integrated circuit, optical sensors, and photovoltaic devices, demands low-cost and reliable fabrication technologies to fabricate sub-wavelength features. Here, we report a programmable nanoreplica molding process, which is capable of producing photonic devices with a variety of submicrometer patterns. The process utilizes a stretchabl...
