FYP Presentation Day

Today is the day for 8 month that i am doing my project that is requirement before i am graduating as degree student in Bachelor of Manufacturing at Universiti Malaysia Pahang. Alhamdulillah, the presentation was going smooth and the panel accept and understanding what i am do for my project. Here is I share some picture in the "nervous" day.Everything is over and now submit for final thesis.tQ :-)

Dean Poster Award

Alhamdulillah..finish already the presentation with the engineer from industry. It make some knowledge and challenges in the industry in the future. Hopefully all the recommendation will do at the future. And now ready presentation for FYP2 soon on 02 June 2014...

Presentation Week

Assalamualaikum and good days,

2nd June 2014 is the date for our presentation of this final year project. May Allah bless all the works that I had done for 8 months. Thanks for the cooperation given while I am doing this project from the beginning until the end. I would like to express my sincere appreciation to my supervisor, Miss Suraya Binti Sulaiman for her encouragement, guidance, morale support, and critics in bringing this project successful. I acknowledge my sincere indebtedness and gratitude to my parents for their love, dream and sacrifice throughout my life. I cannot find the appropriate words that could properly describe my appreciation for their devotion, support and faith in my ability to attain my goals. To our panel Dr Amir Azizi thanks for your comments and I will practice it in the future. The last but not least, I am also very thankful to the staffs of the Faculty of Manufacturing Engineering CAD/CAM laboratory for the usage of computer for this project. My sincere appreciation to my entire course mates with their sharing and helps during my difficulties in completing my work for this project. Lastly, to individuals who has involved either directly or indirectly in succession of this project. Thank you very much.

                 ##DOAKAN YANG TERBAIK YE BLOGGER## :-)..XOXO...PUBLISH...!

Future Recommendation

From the results that have been obtained in the previous chapters, the following future works can be recommended:

1.      Using other simulation software.

·   It can be using the other FEM software such as Moldflow or Solidwork software so that the accuracy on this software can be compared.

2.      For increased confidence (accuracy) of the simulations          results, further work on such simulation on polymer flow by taking picture of a real parison and measure its diameter and compare with simulation process.

·   Measure the real parison and real bottle.

·   Redraw again as same measurement of the real bottle and shape.

3.      Comparing the simulation process with the actual fabrication process work.

·  By taking the both result and comparing the result and analysed

4.      Change the shape of bottle to more complex shape.

·   It can see the more stress effect on the bottle.

·  The thickness on the bottle can be predicted.

5.      Change the material to the other material.

· It also cans trial and error on the Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), and High Density Polyethylene (HDPE material.

· Also can do with the composite material such as glass fiber and other composite material.

·   It also can reduce the material cost.

6.      Variable of pressure

·   Increase the pressure to reduce the time step.

Summary of The Project

Blowing extrusion in mould is one of the most widely used techniques for the production hollow plastic product in order to survive in the competitive market and achieve customer satisfaction. Therefore, this project covers the areas of simulation works on blow moulding process to predict the final wall thickness and stress contour occurred at four different parison’s diameter which are 8, 10, 18, 20mm in polypropylene material. The simulation software used is ANSYS Polyflow software. The simulation works focus on five stages which are geometry, meshing, setup, solution, and results process under structuring and solidification of isothermal and transient flow of Newtonian fluid in complex geometries. The thickness and timestep during the blowing process are studied. The results of the investigations reveal that the 8 and 10mm diameter parison has a better contact with the mould cavity while 18 and 20mm parison diameter has a poorest contact. It is because the pressure not enough to blow the parison and the parison diameter not appropriate with the mould cavity. Stress may occur at the bottom of the bottle because at this point the thickness will increase from the wall bottle to accommodate the volume of the bottle. As the conclusion, 10mm diameter of parison is the best selection parison because the parison it is fully contact on the mould cavity and the thickness is relevant to produce in actual bottle. It also can save the time producing and reduce the rate of the material usage.
