How blow molding works!! 

Rare to find videos like this that aren't just advertising a machine!

I've built them extruder heads before for Ford interior door trim panels. I also built the heat staker assembly unit that assembled the components together. I'm a 31 year machine builder, tradesmen and now tooler. I love my trade!!!

Have you ever made holiday decorations, like Santa's, snowmen, or jack-o-lanterns?

pretty fascinating. Ever since I was a kid I'd look at a milk jug or a toy and wonder how they molded it.

I worked in a milk plant in Huntsville Alabama from '99 to '02 and we made our own jugs. I was fascinated the first time I saw it. I was there one day when routine maintenance had to be done on the machine. They were in the process of purging so we took some of that and made a baseball bat (extremely crude) and a few balls. You don't want to get hit by that stuff. It's extremely hard and dense. I got some the next time and made a hammer. I had to put it through quite a few heat cycles to get it how I wanted it but I was able to drive 16p nails into pine studs with it. It was unstoppable!

Nice work! You should have auto deflashing built-in to the machine. Minimize the work-load on the packer.

I work for the Jones Plastics. We do injection molding, crazy to me how similar yet different all of this is.

I just got to say thank you for the video. I have worked at a that dealt with the little pellets for plastic molding. I have always wondered how they turned that pellet of plastic into stuff. I had a idea but wasn't sure exactly. I would mind even more videos about them it's a really neat process. Thank you for bringing us along.

Cool! Thanks for the lesson as always.

Great video, and I love your enthusiasm! Thanks for teaching me about blow molding!

Thank you. Cool stuff. Work safe.

I like the "no touchy" tape over that top button on the control panel. Lol

Very detailed *how it's made* video I'd like to see more 😀

Luvn the info❤

Fun to see. I made twine for close to 20 yrs. Very similar on the extruder. We made ours into a sheet than the went through an oven st stretched it into tape. The twisted into spools of twine.

I’m interested in knowing more about blow molding

We just acquired a blow molding machine but it's producing more scape than the real containers. The blow molding pin is damaging the container necks

Excellent example

A long time ago I worked for a plastics company in Reno, NV. as a machine operator. I had to walk through the blow molding department to get to the department I worked in. I typically ran a couple of thermoforming machines (hot sheet of plastic lowered onto a mold then vacuumed into shape). But occasionally I would run a CNC 5 axis router. Most of the parts that I made were the plastic pieces that go inside of slot machines (like coin hoppers), or car parts. The company had several other departments: acrylics, press molding, injection molding, we even had our own recycling (chipper) machines.

A couple questions: 1. Is the whole screw apparatus heated to keep the plastic molten? 2. Is there any risk in the plastic burning if it's kept at a molten temperature for too long? 3. Is the mold itself also heated? Thanks for making the video!! I appreciate you doing it.

Im used to seeing trim tooling and punch cylinders. That sucks you have to hand trim them!

Nice jugs! But seriously, do all of the jugs get tested, like with a pressure test? I work in quality at an automotive plant and an Off-road vehicle plant before that, and I'm curious about how inspection and testing goes into products.

What are the tests that the product should pass by the quality team? Please can you do a video about that?

Any information on adjustments on the blow press bar?

Great video, very informative! Older BM machines require manual deflashing, unlike many modern machines that integrate various automations such as leak testers, automatic deflating or post-cooling stations for large jerrycans. What are your thoughts on the All-Electric technology?

Awesome video... it's always nice to see when people do what they post. What I mean is.. you and your attention to detail. Well maintained machine there, she shows some aging but still runs smoothly. Thanks, for sharing your playground my friend.

Great video. We make bottles in our plant and fill with carbonated products too. Our 20oz line has two blowmolder one can run 20,000 bottles an hour the other one runs 16,000 bottles per hour. Our filler runs product into bottle 800-900 per minute. Our 2 labelers run 500 BPM each. Packer does 40 cpm. Palletizer does about 1 pallet 3-5 minutes 49 cases per pallet. Our full pallet conveyor hold about 10 full pallets. The warehouse forklifts on a good day can't keep up with the line. We can run over 30,000 cases of 20oz in 24 hrs

So like some manufacturers do does the flash go back to the beginning of the line and get reground up to be sent through again?

Excellent content. Are the caps next? Do you make those as well?

Wow it’s so old that machinery, did you use deflashing?

Good video. I worked in plastics for years. Nice to see that machine. Do you have stretch blow molders and or sheet extrusion machines ?

Can I make a blow mold plastic slide like a step 2 slide?

Very interesting... and I'm full of questions. Is blow molding the only process you have at that plant? Can the dies be switched out to make different shapes / sizes of bottles? Do you also make lids for the bottles at your plant? Are the lids also HDPE?

Pretty cool, but was hoping for a wheel machine... those shuttle types put me to sleep!! Good video though.

Sir what mold temperature of pp blowing and pet blowing? Same @ plastic injection?

Our latest supplier can't get the threads right, so after they are filled the caper can't put them on properly, gets very messy very quickly. I have a video if anyone is interested.

How long did it take you to get good with that machine? Im looking for a new job and i hate HR saying you dont know anything when even someone in the field for 5 years will have to learn the ins and out of a unique machine

But onc stetson not active

Hey Dan, I noticed when you were showing the control/operation screen, I noticed an American flag and a Chinese flag. Was this machine made as a joint venture between both countries?

Should that door be opened with the machine on?

i want to buy a blow molding machine. Is it available for sale?

Is that the normal operating speed? It seems pretty slow

Timers are the Honeywell timers?

What brand of machine is that

Why only running one side ? Would you be interested in working for a Succesfull growing blow molding company ? I can help you.

Trader horn? I'm not sure if that was a joke but to the best of my knowledge trader Horn went out of business
