Finding efficient frontier of process parameters for plastic injection molding
Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...
متن کاملMolding block copolymer micelles: a framework for molding of discrete objects on surfaces.
Soft lithography based on photocurable perfluoropolyether (PFPE) was used to mold and replicate poly(styrene-b-isoprene) block-copolymer micelles within a broad range of shapes and sizes including spheres, cylinders, and torroids. These physically assembled nanoparticles were first formed in a selective solvent for one block then deposited onto substrates having various surface energies in an e...
متن کاملPVT Properties of Polymers for Injection Molding
PVT (Pressure-Volume-Temperature) properties of polymers are important for both engineering and polymer physics. Fig.1 shows the typical PVT diagrams of an amorphous (a) and semi-crystalline polymer (b). PVT diagram describes the specific volume as a function of pressure and temperature. Specific volume increases with the temperature increasing. There is a thermal transition in the polymer. The...
متن کاملMicrominiature molding techniques for cochlear electrode arrays.
We provide a general method for producing a variety of small, complex electrode arrays based on injection molds produced using computer-aided drafting and machining (CAD-CAM) procedures and a novel method for connecting to the very fine electrical leads associated with the individual contacts of such arrays. Cat-sized cochlear electrode arrays with up to eight contacts were built according to t...
متن کاملInformation System for Injection Molding Tools
Tools for injection molding are very expensive parts of this kind of production and they must be handled very carefully. An important part of their handling is the management of data related to the tools. The important data for injection molding tools is possible divide to different areas economical, technological, production etc. With an increasing impact of information technologies on manufac...
