IT HAS BEEN 5 YEARS since Proton adopted a technology known as HOT PRESS FORMING (HPF) which was used in some of their latest car models.
QUOTE
“In order to develop the REinforced Safety Structure (RESS), Proton acquired the Hot Press Forming (HPF) technology, making Proton the first carmaker in the ASEAN region and eighth in the world to acquire the Hot Press Forming technology. In the HPF technology, steel pieces are heated to 900 °C and the red hot steel pieces are stamped before being quenched at 4 °C, changing the steel phase from austenite to martensite. The process increases the strength of steel parts from the original 500 MPa to 1,500 MPa.”
ACADEMIC DISCUSSION WRITTEN BY MALAYSIAN ON HOT PRESS FORMING (HPF):
1) “Evaluation of hot press forming parts for Euro NCAP 5-star in Proton Preve” - http://dspace.unimap.edu.my/xmlui/bitstrea....pdf?sequence=1
2) “Optimization of quenching process in hot press forming of 22MnB5 steel for high strength
properties” - http://iopscience.iop.org/article/10.1088/...50/1/012064/pdf
3) “An overview of high thermal conductive hot press forming die material”
development - http://jmes.ump.edu.my/images/Volume_9/14_...and%20Aqida.pdf
Laboratory crash test might not tell the whole truth about vehicle’s crashworthiness. So why not we see for ourselves how these HPF-equipped Proton cars perform in the real world.
We have seen time and time again how people simply perish in car accidents. Sometimes the whole family was wipe out in an event that probably takes mere seconds. They’re all gone. Forever. And most of the time, it wasn’t even their fault. It’s heartbreaking.
From car safety point of view, they are two types of carmakers in MALAYSIA: (1) the FIRST WORLD carmakers that make cars to comply with the THIRD WORLD safety standards; OR (2) the THIRD WORLD carmaker that makes cars to comply with the FIRST WORLD safety standards.
The BRAND power is strong. No matter how hard that carmaker is trying to sell its safe cars, Malaysians are still going to buy that freaking Dugong which is probably made out of a few thin layers of metal sheet. When accidents happen, there will be a group of people that going to suggest an alternative to that Dugong, and there will be another group of people that going to say “kalau dah takdir, naik kereta kebal pun boleh mati”.
Feel free to post photos of accidents involving any of these HPF-equipped models here.
You may use https://ctrlq.org/images/ to upload the photos and hotlinking it here. [No registration or sign-up required]. I would appreciate if you could include a short commentary on that accident such as what types of vehicles were involved and whether or no there was fatality.
