You can mix the liquid color with raw material outside inside a batch mixer. then load to machine by pipe or manually.
It is a temporary and messy solution but, mostly solves our mixing issues.
Hello All,
I agreed with a company for manufacturing series of storage boxes.
Numbers are too high, therefore cycle time is important.
We did initial trials of molds without any cooling. All lids...
Dear Friends,
This is my first post after long time. During last 2 years, I was mostly working at the commercial side of office. So, a bit rusty here...
I came with a question here.
We produce a...
This also happened to me (Kraussmaffei 420t). It sounds like not creaking but breaking sound. But very loudy one, I can hear that from my 75m away office.
It happens in different stages

Hello All,
Im trying to fix this mess from half MB bags everywhere.
How do you store masterbatches ?
There is such an equipment;...
Thanks for the answer,
Currently, I have problem with non-hygroscopic material (PP) coming with octabin. Condensation during shipping may cause this ? But if it were, i think that would only be...
I have 4 different material and receive the materials with 25kg bags for now. (ABS, MABS, PP )
I want to switch to 1 ton delivery to reduce handling. and I would like to know advantages &...
Unfortunately, pre-colored material is extra %20 cost.
Any information, how to find saturation point of MB to ABS. How to do it injection molding machine by myself to check the MB performance?
comparing you I am new to injection molding -only 5 years-. But I also have an embarrassing story..
Once I was working on a 150t Arburg machine and I had colour/material mixing problem. Screw had...
As I understood from " locked out", you mean machine doors must be opened and not be able to close during mold changeover.
We also spend intensive effort on machine safety of injection molding...
Great, I also use residual melt cushion, inj. time and peak inj. I am not very aware of methods but I think measuring the part is not a criterion for machine performance, isnt it ? Of course for CpK...
Ok, I will do it. I already have your book :)
This was a discussion with mould maker just 30 mins ago. They said, when I use lower temperature I will need more pressure and this will lead to...
Which of the below leads to more flash on mould ?
20C mould temperature and high injection pressure,
or
40C mould temperature and relatively less injection pressure.
Processing PP on 650t...
I am performing CmK study for machine acceptance and here is my question;
What parameters do you use for CmK analysis for injection molding machine ?
Do you use holding time or less holding time...
Hello,
I am asked if it is necessary to make MFI test for incoming materials. I said it is nice to have, but I have never used this machine before and I do not know exactly how to use information...

Now I understand why you insist on clamping through the mould plates :))
Also for me, SPC and FMEA forms would be beneficial. Actually I am wanted to make process FMEA for injection molding machine and I am not sure how to summarize all related topics into FMEA :)
In european machines I have never seen two different 2nd stage (pack and hold). There is only 1 and called hold :) (There is 16 stage profile you can add of course but all called hold)

You need to achieve turbulence flow for each flow lines. Turbulence means Reynold number is over 4000.
First you need to know nominal diameter of your cooling channels.
Then You need water...
We were working with a world wide company. Now we switched to a local supplier for new factory. Time will show how quality is effected.
Fyi: ABS is from BASF, MB was from Clariant and now local...
