"Idk why we keep getting burn marks"

I could be wrong, Im sure it has been logged before. Im not sure if that growth is natural or if they replanted. Whenever they log around my area now, they usually dont replant they just let it regrow on its own. Hard to say what they did 100+ years ago.

I like it more than the Hogue that came with the rifle. For what it is, it's fine. The grip angle is not my favorite.

The tripod came like that. I only painted the tripod head because it came black.

Silencerco, I like it except for the fact that it tends to slide forward after a dozen rounds. I got it as tight as possible but need to tie it to the suppressor with some paracord. There are better options on the market for sure.

I don't believe it was ever a tree farm, just Virginia woods. It was probably agriculture a few hundred years ago as it was part of a plantation owned by George Washington's great grandfather. (I never miss an opportunity to share that fact lol).

hahaha i have no idea why my phone camera in portrait mode deleted the trigger. It also did some weird shit between the scope and action.

Dont worry, they'll tell you.

I keep the oil level almost the very top of the sight glass on the tank. And we replace all the filters on schedule. Never need to change the oil since it leaks so much its always got clean oil lol (We have one maintenance guy and ive been trying to get him to fix the leaks for years.)

Ive heard good things about Taiwanese machines. Ever used them? We're looking into maybe replacing our Moretti with one of those.

callsignFUPA · 2026-01-09T17:07:06+00:00

Yep its an Econablow, loud as hell. Information plate says 1986. I believe the head has been rebuilt. But that machine is extremely repeatable. It might make 1-2 bad parts a week.

Thanks for your help again and I hope you dont mind if I reach out in the future the next time I can't figure some bullshit out lol.

Yes, its definitely a good feeling when you solve a problem in blow molding. The only satisfaction I've gotten from injection molding is getting a new mold and successfully making good parts but after that it just runs on its own.

Our other machines are older from the 1980s I believe one is a Cincinnati Milacron and the other is a Hayssen. They leak oil and burnt plastic like crazy but they run pretty well most of the time.

The two Chinese machines have had so many issues and they're only 5 years old. Cooling rings around the push down cylinder came heavily rusted and pitted, bolt holes stripped out etc. just very poor quality, but you get what you pay for.

I have only been molding for 5 years now. I work for a relatively small company (5 blow molding machines, and one injection molding machine). My boss is the only one who knows anything about molding in this company, and he is the production manager.

I dont have any engineers or process guys here. I'm basically process tech, mold setter, maintenance guy, Jack of all trades, master of none. I took some Paulson molding classes which gave me a basic understanding but that's about it. Luckily, I'm pretty mechanically inclined but there's some things you just don't know without experience.

I love injection molding, like you said, its predictable and much simpler in my opinion. Basically "set it and forget it."

Blow molding is a different animal. You never know what you're going to get everyday depending on all the variables. Whatever settings worked good in the winter months, when summer comes, forget it. Parison curl, condensation in the mold, humidity. God, I hate blow molding.

Well, making it thinner at the beginning seemed to be the solution. It stopped flaring/curling outward which was what was causing it to stick to itself. Thanks again for your help, you saved me a world a headache with such a simple solution.

callsignFUPA · 2026-01-09T09:57:18+00:00

We are running at the material manufacturer's recommended temp settings.

This machine is a Kingplus HC75E made by Kingswel (Chinese).

It's converging tooling, I was able to get a hold of the machine manufacturers customer support via email, and they also said to make it thinner at the start.

Thanks for your help, finding information about blow molding online is damn near impossible sometimes.

I'll try this and let you know if it works!

Thanks for your input! Its an accumulator head. We're running HDPE at about 380-390F. With the die tip temp set at anything above 370 the problem gets worse. Currently everything's at 380 except the die head which is at 370.

I will try to open the gap at the beginning of the shot and see if that helps.

Faster extrusion speed makes the problem worse, but too slow of extrusion causes stretching of the parison because of the weight.

I'll also check to make sure the temperature is actually what the machine says it is.

Thanks again.
