Guys, please allow me to explain, I have prior experience (1 year) before continue my degree studies. So it's not consider that fresh. Anyway, thank you for your numerous feedback.

Hi bro, I'm also a mechanical design engineer but with 2.5 years experience. Just jumped into my current company a few months back with salary around 4.5k. May I know where are you located and how much % increase did you get jumping from design to production? How's the production life compared to design?

There's not so much choice in terms company for mechanical design in Malaysia. From what I observe, it's either you got promotion once in 2-3 years or jump to another company is the fastest way to boost salary.
