Rotational Molding or rotomolding from ASH industries is a process for plastic part creation. Rotational molding machines create parts by rotating parts on an axis, which thereby force the plastic material to stick to the walls of the mold - hence why it's an ideal process for creating hollow parts.

Rotational molding, which is also commonly referred to as "rotomolding" or "rotational casting," is a common means of creating plastic parts that's increasingly gaining traction as an alternative means to plastic injection molding and other plastic producing processes. A big reason is because parts that are challenging or impossible to create via plastic injection molding, blow molding and thermoforming - such as hollow parts, partially enclosed parts, large and small parts and parts with other complexities - can be crafted via the process.
ROTO-XL™ represents ASH’s unique roto-molding division focusing on tooling & hollow thermoplastic components up to 18’ long and 52” in diameter. ROTO-XL™ molding is a cost effective alternative to injection molding for large plastic parts, components which must be hollow (such as berms, barrels, canoes, kayaks, slides), and those which may be made from commodity thermoplastics (polyethylene or polypropylene).

At ASH Industries, we have the ultimate tool to help when you're designing your part. The N.E.R.D. (New Engineering Reference Device) demonstrates real world molded radii (both inner & outer), wall thicknesses, textures, absent & present weld lines, as well as demonstrations of sink & no sink. This clever device can save you thousands of dollars and prevent mistakes from happening.
Made in America: ASH® is proud to do all our injection molding manufacturing in America, no outsourcing. Every point of our process is done right here in the USA, at our product manufacturing facility in Louisiana. We work with clients all over the United States and can ship products nationally and globally.
At ASH Industries we are always looking for ways to help you get real parts into your hands rather than waste money on 3D printing. If you 3D print parts to field test or to try something for a new product, you still have to spend the money to go into production. Our SuperMold™ program gives you the parts, tool and puts you in the spot to start production right away. (SuperMolds have these limitations: Parts must have a maximum 3/16” wall thickness, +-0.005” (0.127mm) tolerances and not have any undercuts. The molds must be “open & shut”).
Ash Industries' Move-A-Mold™ program can help you begin production of your components within one week. If your group has existing molds and you wish to benefit from ASH’s talents, you can move your molds with absolute assurance that your needs will be given priority.
MIM (metal injection molding) works similar to the other injection molding processes - powdered metal is combined with a binding material and then injected into a mold where it's left to form and curate. The end result is a metal part. The process is ideal for the short and long-run production of metal parts, especially those that are smaller in size and more detailed in terms of properties.
Silicone liquid injection molding, or LIM, is a manufacturing process commonly used to make silicone parts (considered a subset of rubber or thermoset) that need to withstand extreme conditions, regardless of the industry. The process is an injection molding process at heart, meaning that materials are injected into a pre-made mold, where heat accelerates part curing. Then, the process repeats itself until the part run is complete.

I work for a rotational molding company of very large septic tanks and water tanks. I've never loved my job so much. I'm so glad I got into this industry!
Thanks for sharing!
The best video I've *ever* seen about Rotational Molding. Thank you.
Wow, thank you!
I like this guy. Landed on this by accident. Who would have thought you could make plastic molding interesting.
thanks!
0:27 Called out, damn
But seriously, get some masks for your guys... dust is no good.
right! i thought that was hilarious
Yeap no masks while handling that fine powered products just plain stupid.
shots fired
I work in a rotational mold factory as a machine operator and honestly that powder won't harm you. At least ours doesnt. The only thing we worry about is the heat coming fro the oven when the oven timer cycles out so the next arm comes out of the 2nd cooling bay.
@@jacobgerig7552 It might not be harmful in short term but long term it definitely can cause harm to your lungs
I worked rotational molding at a company but they had just closed down our plant and relocated to a different state. I’m going in tomorrow at this other job that does rotational molding! I’m glad I could find more work that I have 8 years of experience
That is awesome! Why don't you call ASH and work there?
Excellent video production!
Learned alot about rotational molding, thanks!
Used to make buoys and fenders for boats back in the 80's with a machine like that, we used liquid PVC instead of powder.
This helped me understand so much for my furniture design project. Thank you!!!
Glad it was helpful!
*_Yeti has left chat_*
Yesterday I discovered friction welding exists
today it's Roto-molding.
Great technology showing here. However, please wear mask when you guys processing or handling the plastic powder. For long term inhale, it might damage your lungs and cause cancer.
Was thinking the same.
Was photographers fault- it was an unplanned shot at end of day- not real
Very informative. Thanks
So simple way to narrate the process. Very helpful. Keep it up
Thanks, will do!
Thanks for this video. I just had this kind of moulding suggested to me and this explains it perfectly.
Glad it was helpful!
Great stuff! Thank you!
Glad you liked it!
Thank you for the video! It was really interesting and the process was well explained!
Glad it was helpful!
Great video! Thanks!
Glad you liked it!
...and possibly purple... cool video! 💜
This was excellent
I am new to Plastic molding and love your video.
Awesome! Thank you!
That's badass.
wow, always wanted to know how my cooler was made!
I love rotational molding
I just bought a roto-molded cooler and was curious about the process. Excellent video!
Glad it was helpful!
Nice presentation. Can water/UV graphics be applied to part surfaces? For example pad print or permanent decals like the toy trike in your video- but bigger in scale, perhaps even masked and sprayed two tone? It’s for a personal flotation device.
Yes you can! - www.ashrotomolding.com - give us a call
Can I make a powder for the mould from a recycled material such as PET?
great companie
can i produce pvc bumps this way and whats the productivity rate and how many molds can i put on one axe
Great video😊!! Can we get a uniform thickness distribution for around 7 mm thickness? And can rotomolding produce thick walls?
Thanks,
While there's no definitive upper limit, walls exceeding 1 inch (25.4 mm) become increasingly challenging in rotomolding. Thicker walls take significantly longer to heat evenly throughout, extending cycle times and reducing production efficiency. Additionally, very thick walls can lead to uneven cooling and potential warping of the part.
Very Interesting!!
Glad you think so!
I know this is a solicitation for business... but I love learning about this stuff!
❤️🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸❤️
Thanks yes they are....but we are trying to keep jobs in America and videos do a great job of telling the story.
Buen vidio
Roto mold is a great way to make some parts. It was shown to me using a bottle of pancake syrup. He rolled the container slowly and the syrup coated the inside of the bottle. Basic concept to show somewhat how it works.
We made a product called The Dally Master using this process.
good example of how it works thanks for watching!
Thanks sir for your video
I am student of tool and die maker
I love you Hartie xx
hi sir...greetings from me ..., I am now working in a plastic water tank company and I am having trouble developing durable molding clamps because so far our company is still using bolts, if you don't mind, can I get a good example of clamps ... and frankly our miulding is not precise thank you.
Why do roto-molding products lose color？
Which material is better for a Kayak? LLDPE or HDPE?
LLDPE is better due to its low density in water for better floating.. If hardness matters than ofcourse HDPE.
Myself from same field !
Genius
The process is cool but the people at ASH are even cooler.
What if I needed a rotomolded guard to maintain it's shape at 100c ?
Then you would want it molded from an atypical thermoplastic. Many are available, but part geometry is a factor. Lets talk
Thanks
Welcome
Can you use "PETE" plastic in in root moulding machines
It is possible to use certain grades of PET in rotomolding machines. However, it is not common.
Good machine and clear explanation.
Can we mould plastic toys parts of small quantity at low cost?
Thanks
We'd love to see what you have in mind! www.ashindustries.com/contact-ash
Yes you can
I work at a rotational molding plant and we do a lot of Ag products. The one thing I like working on is Kayaks.
Good stuff
How long does the process of making water tank happen?
Hi. It takes apx 1 hour to complete the cycles dependent on size
It depends on the size of the tank. The largest tanks can take 4 hours from start to finish.
Great Evuro need plastic molding
how to fill up the foam inside the finished product.
Hi Junaid. That foam is likely a 2 part polyurethane foam. After the product body is molded, both parts of the foam are injected into a hole. When the two parts combine in the molded part, they begin to form foam, expand, and then solidify. The expansion of foam creates a lot of heat and pressure. Any small hole that isn't plugged will shoot out foam.
saw this at tonka toys, but wow
Is the powdered plastic not harmful? Feel like dust masks should be used in factory to prevent inhalation.
Agreed, but at the time of filming it was thought to see his face. Production mistake not a procedure mistake. thanks
I've been working in roto molding for 5 years we don't wear masks they jus fog up your glasses but I'll be honest we prolly should smh as long as that damn machine is going in circles it's a go!
Good video, the presenter is hilarious
Indeed‼
I did make the float molds for them. With their spider.
what is the of benefit float? And for what the float is Made?
Bravo
Super plus bravo plus bravo
bravo3
can we change or add more thickness to the products?
Yes. It's custom to your needs!
@@partgurus awesome 👍👍👍
Hello, how much would it cost for one product to be made using your machines in general ?
there are better ways to prototype - for one? 3D print?
Build so many things this way wish the products was cheaper but gotta pay the people
And especially good people- we take care of our people.
No respirators. OSHA would have a field day in there.
Our mistake - we were filming and not actually producing- cameraman oversight- they are always safe when manufacturing
Good ass video
I'm surprised those in the video don't wear any PPE or masks when dealing with all that dust.
For anyone familiar with the process - does YETI brand use any significant technologies or processes to differentiate their products from other rotomolded coolers? Or is it possible that YETI and other brands are made on the same machine using the same process?
Probably better quality material. But same process.
Something tells me they're all made by this company.
Same thing. Except their plastic is much THICKER and the amount of foam inside is thicker as well. Even the lid is insulated with foam. Most coolers have no foam in the lid.
I use the process for Plastics lining of Steel Pipe Fittings. I need a larger macine which can take the load of Large steal pipe fittings. Can you supply a costom made machine for me ?
ASH does not make machines but y9ou can try www.automationmachinebuilders.com/
very cool process , but it looks like a slow process loading the material by hand.
much of custom manufacturing for lower volumes is done by skilled people. Robotics isn't always economical.
How big can you guys do
Kayak Size
I run the Rock and Roll Roto machine
Should probably get the guys dumping the plastic powder into the molds some masks!
AGREE! that was set up footage a long time ago as the video guy needed a demo. they wear full protection in production.
and automatically our electricity is also still manual and we are also having trouble changing it
I work at a roto-molding factory, we got so many spider arms
What do you make?
@@packagingscientist9530 hi Christ do you do Foam injection?
whats low cost to yall? say a 30 x 40 closed
cylinder
give us a call to discuss. Tel. (800) 598-5274
So the plastic sticks to the walls huh?
not sticks- its a release mold- it settles due to the forces
@@partgurus So it settles and dries? How would it dry though if it keeps rotating into the heat?
sorry, I wanted to say in roto moulding machines
It's my machine! Rising Sun rotomolding in china.
these machines are very interesting
but it doesnt give me the definition.
Yes you can get definition- its based on the mold
Can you make my patent 10525174 ? I am also looking for co-inventors and to take these to show and sell I am old 85 and no spare money so I want someone to take over when I go. Thanks, Rex R. Bahr
Non practical for larger quantities until robots used
Ive been at my job for 4 years and our rings are so much smaller we have 3 or 4 molds on each side with only 11 minute cycles damn I would feel like a god at a much more spacious plant 🤣🤣 🤣
need a job c'mon down!
Wait, you’re not Phil Swift...
Big on moulding BUT not big on wearing dust masks. You can see the pulverised plastic in the air! Good luck breathing in that stuff all day long 😱
You are so right! We filmed this as a demo without thinking of the optics- they do wear masks....
Can women be a molder? I've heard it's extremely physical
yes you can - it has lifting of resin involved but most other parts are using hoists
Surely a mask has gotta help when that plastic powder is floating around in front of your face?
Yes- cameraman take the hit on this one. It was not really a working scene it was last minute "get in there for the shot"
Please wear masks while working here, the dust from plastic powder can cause micro plastic ending up in your lungs
These people shouldn’t be breathing in that plastic..
they wear masks ... we were were filming... no worries
large foot print, labor intensive , slow production.
Good
At least it’s low cost
Cheaper, Larger parts, easier processing.
Low overhead?
Why aren't masks worn when pouring that very fine plastic dust into molds? Small plastic particles sound like bad news for the lungs.
Blame the vidoegrapher...was only for the shot- masks are regular use
@@partgurus Great to hear!
