Machine Design & Development
In today’s Global technological scenario, Innovative Product Development Cycle has become very important for competitiveness. Rapid Technological changes and advances in CAD/CAM/CAE including virtual prototyping have enabled shorter cycle time for innovations.

3D CAD Model of High Speed Braille Printer Machine Design Development Group (MDDG) in CMERI is equipped with a number of workstations networked extensively with high end PCs. Modern software tools e.g. I-DEAS, CATIA, MDT, AutoCAD are available for analysis, design and drafting.

This group undertakes development of various types of Special Purpose Machine (SPM).

Following SPMs has been developed by MDDG ( or the process is under development ) :

Cricket Ball Stitching Machine
Stitch Bonding Machine
Cricket Ball Throwing Machine
CTC Roller Sharpening Machine

 Important projects going-on
Automatic Fruit Sorting and Grading machine
Automatic Machine for sharpening / resharpening of CTC Tea rollers

Development of High Speed Braille Printer

MDDG is also integrated with the Electronics group to carry out automation related projects.
