based on our requirements and resources we identified a set of objectives and a time bound gantt chart was made
OBJECTIVES
1.Design and development of a twin screw extruder for mixing of nanoclays with thermoplastics which can be used in future for the purpose of polymer research in IIT Delhi.
2.Test the microstructure of the product obtained by the extrusion from the above mentioned machine to check if the mixture is in homogenized form upto the nanoscale
DELIVERABLES :1st semester
Project proposal , work plan and gantt chart
The designed parameters for all the sub parts of the twin screw extruder: their 3 D models made in solidworks2004 , Engineering drawings
The process sheet for the fabrication of the screws
The screws
A progress report on the work accomplished as well as the deviations and their analysis
DELIVERABLES :2nd semester
Process sheets for the fabrication of the barrel , die , hopper
The final copy at the end of the semester of the project report
The twin screw extruder
Operation and maintenance manuals , users manuals
Extruded nanocomposite and the validation , calibration manuals
Statement of expenses
Project closure statement
LEARNING COMPONENT
Manufacturing processes and process planning
3D modeling using solidworks2004
Hands on experience of working on an CNC machine apart from the machining experience
A little about nanocomposites and their method of preparation as well as the advantages it holds in the polymer world
Most important , the experience of a research and free thought environment
