Rick,

I will take that into consideration.
By the way, what do you thick of my findings with the condition of the heater system? I know it too outdated and perhaps the cause of too much...

Rick and Jendalf,

Here is the after image when we open the hot runner system.

Dear Rick and Jendalf,

After I checked the condition of the mold and runner I found that it has no shut-off valve and just a free flow system. I attached the picture for reference.
Now, looking...

Rick,

We are also looking forward for the resolution of the problem and at last, you are correct, we can take some nap time. :)
I will take your advises.

Jendalf,

It is unfortunate that I do not have the picture now but the void is inside the plastic. Now the concern is, that the product is a case that we place acid, then later due to unwanted...

Josue,

We also experienced this problem, I bet most of us I believe.
Considering the appearance of your product, first try o check the channel as they mentioned for the uneven surface or...

Rick,

Yes. I mistakenly accounted the friction to flow restriction.
By the way, this is another issue, but we observed in most cases, that our product under this mold (and heater) frequently...

Jendalf,

That is nice to here from the INCOE themselves.
We will try to consider of lowering the heater temp from 300 deg.c and see what will be the possible effect on the heater itself.
...

Rick.

I think the friction has less chance for the cause but for the excessive cooling, I think we have some issue here; but I will try to consider verifying both idea to see where the problem...

Rick and Jendalf,

Please correct me if my understanding is not inline with what you wanted to explain, but this tip expansion basically restrict flows, correct?
Does it really causes the nozzle...

Jendalf,

Yes. I believe that also. Perhaps the heater actual power output is already below the input value. I will consider also checking the calibration status of the heater.

Thank you!
...

Jendalf,

Sorry but I dot quote understand your second instruction, are your saying that I should increase the HR temp than of the barrel with +5/-10 deg. C variance?
I appreciate if you make it...

Rick,

That is quite an explanation but for that, I really got the point.
Tomorrow I will visit the plant for they reported another similar problem. I will apply all the information I have...

Dear Rick,

Yes. That is actually what is happening. We are also looking for the possibility of suggesting to change the setting to increase the barrel temp instead of the runner heaters.
Yes....

Dear Rick and Suhas,

The material is PP and the melt temp is set from 210 to 220 deg. C while the hot runner heater is set from Zone 1 to 7 with 366, 365, 351, 280, 327, 351 and 370 deg. C...

Suhas,

The nozzle I am referring is for the hot runner nozzle.

Dear Everyone,

Good day!

First I would like to thank everyone especially this site to where I learned the way of scientific molding.
Now, for my concern, we have molds in our customer that...
