Test Steps :
Sample Preparation
Loads used 500gm, 1000gm
Heights we have used 50cm,45cm,35cm Find the Break point
Convergence & Confirmation of result
Samples EX2 Machino Polymers India
6.Du Pont Impact
Test Samples
Observed no breaking of the sample till 4.9 joules and similarly in future I can find the breaking
point or maximum impact the material can absorb in deciding which material to use ( we want
maximum energy to absorb instead of cracking, as while minor accidents also it should not bedamaged)

Title : Bony Polymers factory visit
Contents:
Processing of MP tubes
Cleaning of Extruder
Purpose : To understand the processing of MP tubes and Cleaning of Extruder
Conclusion: Bony Polymers visit is very satisfactory and one flaw found is there is
no clear work instruction for cleaning is attached near instrument. Learnt the processing of tubes
Why cleaning is very essential in Extruder

Title : Kansai Nerolac Paints factory visit
Contents:
Process
Purpose : Pearl White Trial
Conclusion:
In case of Mica Base we observed both DFT & Pigment Conc are effecting, So we need to
control both to make optimization In case of Base Coat there is no significant effect observed
Concluded Mica Base is a key parameter

Training
Conclusions: The training is very helpful in first-hand experience of works at HGID.
The exposure to various plastic and rubber materials used in cars will bebeneficial in the future working.
Material knowledge, testing and process know-how which learnt dailyfrom the mentors are essential to any R&D, and hence will be useful in
the future.
Study of various test methods and their importance is necessary forfuture localization & development ,and will try to contribute to HGID.
Study of fabrics/plastics/rubbers will help to apply it in the future materialsfor Honda Cars.
Will try to Give my best contribution to HGID, with the knowledge andexperience gained through the training.
