Question by Tar: Does anyone in California or elsewhere feel the plastic surgery pressure?
I live in the OC and everywhere I turn I see plastic surgery.
I see the old ladies with their stretched faces and crazy eyes then the soccer mom’s, and then the younger girls with their perky D cups. Usually it never got to me, especially since growing up in the Midwest, but lately as I cruise the beach, the bars, myspace, facebook…. ahhhh… you name it, it just surrounds me. I use to make fun of the girls with all the fakeness but now as one after another of my friends gets another boob job, nose job, and lip injection… I am starting to doubt myself. Now I want something done just so I can be in the club. Sounds ridiculous but the mentality that surrounds me tends to love the perfections of surgery beauty. Does anyone feel this weird pressure? Does anyone, ladies and guys, think it’s becoming cliche?

Best answer:

Answer by lonbear2000
Any lady that gets a boob job should be smacked. Many, many, of us men love the smaller busted ladies (A cup). I can understand some procedures like if a person lost a lot of weight and needed to have skin removed.

I do not think there are enough surgeons to help me.

Question by Sanjay B: is more flow or more pressure better for heat transfer in a frp cooling tower?
We have plastic injection molding machines and frp tower is used to cool the hot water which flows through the mold and machines

Best answer:

Answer by rswdew
you want more flow, pressure will build heat in one place. The tricky part is that you need pressure to create a greater flow!

A FANUC Robotics six axis M-710iB/70T top-loader robot pulls a molded plastic part from a large plastic injection molding cell. The M-710iB/70T then carries the part to a table and performs an automated tool change. The robot then trims and removes any plastic gating from the part with a cutting tool. After all gating has been removed, the robot performs another tool change and relocates the part to an out feed conveyor to complete the cycle. This automated process then starts over with a new molded plastic part. This six axis M-710iB/70T top-loader robot saves valuable floor space with its vertical mount above the machine, allowing easy access to the molded parts. The flexibility of this six axis robot allows it to perform multiple automated tasks in a wide range of work spaces.

Question by Robert R: For plastic injection molding what are the 3 significant factors from back pressure??
3 distinguished factors that back pressure might lead to for injection molding. I would like an explanation for each.

Best answer:

Answer by Edesigner
First there is STRIATION-this is thickness incompatibility…,,, then there is HONEYCOMB- this is the hole you see in the plastic where there is not suppose to be a hole… and there is also COMPACTION –this is when the air is pressurized out of the plastic making it a too brittle …All of these can be controlled by temperature modification and of course pressure..there is also another problem which factor into injection molding this is draft point- the place where the little piece of excess runs out and in the actual process if bead are used contamination will really blow out the dies …after all that’s what we need to save the most are the dies……Well there ya go …Good luck with the plastic billet business..From the E…
