We currently have a few molds that run in semi-auto and require a full operator to run the press. The operator needs to spray the mold every cycle so the parts release.
Has anyone had success...
I would say almost like a combination of burnt and acidic.
Hi all,
We recently received a large quantity of PP resin in. As soon as we received the resin in there was a terrible smell to it and it was making some of our material handlers woozy even being...
Hi all,
We are currently using a foaming agent on a transfer tool from another company. The foaming agent is used to help eliminate the warp. When we cut the part in half we notice that there...
Is there any sweating occurring in the mold. (Condensation of water)?
I don't believe there is a shut off in the mold to run one part at a time individually.
The part is a family mold with two separate parts. One of the parts a lid was experiencing warping while the bottom cover (the other part) was experiencing the dimensional shrinkage (around a larger...
Two problems. One is warping and the other is dimensions being too small.
We have placed a foaming agent in there to help pack the part out greater (do not know how this will effect the shrinkage). We also got this as a transfer part from another molder an we have no idea...
I know PP tend to have a large variance in the shrinkage from one grade to the next/One manufacturer to the next. Does anyone have any recommendations for PP with low shrinkage rates?
We use gas assist injection molding with some part we currently run. We use a generator to generator our nitrogen and when the nitrogen generator is not keeping up/is broken we tend to get part...
Yes, the pullers and stripper bolts seem to be falling apart or breaking.

We are currently running a 3 plated mold with a stripper plate in the middle. When we try to run the mold in fully auto the hole mold falls apart. When the parts are run in manually the mold will...
Cross linking in plastic means that the plastic molecules are chemically bonded to one another. The chemical reaction that bonds the thermosets together("cross-links") can be anything from a...
Hi all,
We have recently been running into issues with our thermolators being off, during production runs and it causeing our mold to be too hot which leads to blistering/bubbles ex...
I was...
IS there a way to store all of that data into one common spot from the app? Could all that data be saved to one place so other people could reference it later from a different Ipad/phone?
The compression ratio of our screw is around 2:1. After talking with a resin supplier they suggested either getting a barrel with a higher compression ratio or doing a reverse temperature ramp and...
We were running the barrel temps at around 535 F and up to 570 F. Our thermolators were set at 120 degrees F. The transfer pressure was around 1000. Recovery time is around 12.4 seconds. ...
Hello all,
I am having an issue with a nylon 6,6 material. There is unmelted plastic pellets in the final product. We have tried melting the plastic by increasing the barrel temps as well as...
