I need help on translating Chinese about polystrene machine, any volunteer??

...

Hahahahaha ... translating from English into Chinese? Have you tried Google or Bing?

just google it and put the chinese word for plastic.

If I had 2 kuai for each time someone asked me to help out with this or that, I could buy a car.

The OP wasn't asking you specifically. Perhaps you'd be able to buy a car if you adjusted your statement to 'if I had 2 kuai for each time I assumed someone asked me to help out with this or that', and you'd probably finish the car transaction 2 kuai up after the salesman asked you to sign the bill of sale. Result! 

nor is it greed. it is a matter of principle.

Is the principle 'these are my internets'? 

...

(continued) ... just a few words? doubtful ... but then, as I read the other day, its truth can never be proven, now that the "case" has ended ...

So what you are kids arguing about? Two kuai? Please ... hahahaha ...
