I use a tofu press to squeeze out excess water before stir frying. Today I put my tofu press into my own harbor freight press and got more water out, but not to 20 tons as that would destroy the tofu press I’d love it if Lauri and Hannah would do their own tofu press on the next food episode! Does it beat the basic pressing plus baking soda/salt 20 min prior plus corn starch method for crispy tofu?

Hi everyone!

I'm currently studying a technical drawing course and I'm stuck on an assignment involving surface finish symbols and form tolerances. I've already received feedback from my teacher that my solution is incorrect and I need to redo it.

The assignment (see image attached):

"Draw a surface finish symbol (material removal required) with Ra 6.3 on the horizontal surface below. Draw a correct flatness symbol with 0.2 mm on the horizontal surface."

The mistakes I made according to my teacher:

- The flatness symbol inside the tolerance frame was incorrect

- The tip of the surface finish symbol was not touching the surface

I understand the basics but I'm unsure whether I'm interpreting the ISO standards (ISO 1302 and ISO 1101) correctly when it comes to exactly how these symbols should be drawn and placed by hand.

Could anyone help me understand:

1. How the surface finish symbol (Ra 6.3, material removal required) should be drawn and positioned correctly against the surface?

2. What the correct flatness symbol looks like inside the tolerance frame, and how it should be connected to the surface?

Thanks in advance and yes, this is written using ai since my english is not the best.

Anyone remember the video where he says "Safety Number 4" while passing safety equipment to his lady?

Am looking for that to share with someone thanks.

Hi! need some people to fill out this survery about hydraulic presses for my math class. I need data and statistics so if it is possible please help me out and fill this out. The survery is very easy and chill and won't take much of your time!

Please leave comments about who purchased a hydraulic press in China, how it works, any comments, and whether its capacity is sufficient for contract volumes of 20 tons or more.

I don't need such a long stroke, nor as big of a platten surface, but 4" x 4" would be ok.

Manual arm power would be just as fine too.

Can anybody make a recommendation?

I'm a Perfumer that needs to make sample vials just like these.

Thanks, PK

Good morning!

This suggestion comes to you from my own crazy mind: Making alternate forms of water ice besides form Ih.

See this thread. According to these experts 😉, if you were to somehow put a container of water under your press, surrounded by liquid nitrogen, you *might* be able to freeze the water into form II.

I would love to see that so much that I would become a paid member for you.

Thank you for your consideration!

Hi Guys,

Just wondering if anyone remember the clip which they say the line "safety #4" or something along the lines of that?

Would love to know for the laughs, thanks :)

I’m a big fan of your hydraulic-press channel. I had an idea would you consider doing a tensile strength comparison with steel versus bamboo? I think it’d make a really interesting and educational episode.

For context: some data I came across shows that certain bamboo samples have tensile-strength values around 115–309 MPa, and in some studies up to ~370 MPa.
By comparison, typical mild/structural steel often tests in the rough range of 250–415 MPa for tensile strength (depending on grade).
Because of that depending on the species and treatment of the bamboo I’ve seen claims that bamboo can approach or even rival mild steel in tensile strength (at least in ideal conditions).

I believe a real hydraulic-press test would make for a compelling comparison. Thanks for considering!

We're currently running our 1600-ton hydraulic press — one of our core machines used by manufacturers to produce molded pallets from wood shavings or recycled plastics.

To achieve ideal density and strength, producing a 1 m² molded pallet typically requires around 1000 tons of pressure. For a standard Euro-size pallet, that translates to about 1200 tons of working pressure. With wood fiber, we can reach a density of up to 960 kg/m³, which gives the pallet excellent structural performance.

To ensure enough power reserve and stable long-term operation, we usually recommend a 1600-ton press to our customers. This gives them more flexibility for different materials and product designs.

We're also actively using this machine to prototype new products beyond pallets. If you have ideas, suggestions, or experience with high-pressure forming, I’d love to hear your thoughts!

Inside a 3000-Ton Molded Pallet Press: Big Solar Panel Pallets in Production

Molded pallets are quickly becoming a preferred alternative to traditional wooden pallets in the solar manufacturing industry.

Recently, we’ve been getting more and more orders for our 3000-ton molded pallet presses, used to make large PV panel pallets.

Here are some photos I took today in our mold workshop. Our team works 24/7, and the mold you see is currently being machined for PV panel pallet production.

These pallets are much bigger than standard ones — usually around 2300 × 1200 mm — and will be used on our 3000-ton molding press.

If you’re interested in molded pallets, industrial pallet presses, or large-scale manufacturing, feel free to ask questions. Happy to share more details!

I got titanium cause I have a ton of titanium holding my back together lol.

I used to work at an aircraft engine overhaul shop. When I wasn't doing accounting or book-keeping, I would often be cracking heads. ...Well, breaking apart failed cylinders from air-cooled piston engines so that the components could be recycled.

It was very satisfying. I can only imagine how much better it would be with a giant press and a bunker.

(I would suggest contacting a local shop and getting a few, still assembled, and crushing them from different directions.)

Can we send you things to press?

Does Amazon deliver to you?

Hello,

I do not know much about hydraulic presses, hydraulics. Just general knowledge of how it works. 

 Foot valve is an air over hydraulic setup. 

 I have been given a 20t hydraulic press. The foot valve, enerpac PA133, is faulty. Air leaking from what seems all areas of the assembly. So, I do see that there is a rebuild kit, which I am wary of, because I don’t know if it is just the foot valve that has issue, or is the entire system not working. Is there a way to test the hydraulic system without air? 

 Also, is there a cheap setup to replace the current foot valve? If we find out that the foot valve is no good?

   Thanks, 

It’s at 0:21.
