I have to share one of my try…
I am sure that @armbouhali will be happy
As my last tries:
Oven 40min at approx. 165deg
Could you imagine cnc Greek alphabet?
find a plastic to recycle
Here a old broken PP toy bucket
find the correct mould
Silicon mould bought on a lie press for 13,65 euros with transport cost included at the time of buy… Now cheaper.
Cut without shredder
Quantity to use
I weigh my previous alphabet to know approximately how much PP I will use.
Fill the mould…
Too big for my actual oven… I cut it in 2. In addition I destroy one part by overheat (triing to clean it)
In the oven
Unmoulding and finition
goddamn that amazing finishing one the surface. looks fantastic. keep up.
Such a good idea, so easy and opens so many possibilities 🙂
How easy was it to remove the pieces from the moulds?
@susanne0570 yes a alufoli because my oven is not so clean… And with the temperature some fat oil/duck fat leak… 🤤
@sharma-sagar the surface is not so bad… I am not satisfied of all of the letters. Some with the bubbles… Some others like the ‘l’ or ‘z’ or ‘n’ were not so aligned.
But sufficient for my daughters to start learning…
@katharinaelleke 2 molds so 2 situations
The kiwi burned one a’k : little bit sticky on some eckig letters (complex letter how to say in English?) but mold safe. I have more sticky things with others tries with this kiwi mold and with impact on its health.
The l’a mold was really easy and not sticky at all.
I didn’t use any spray or Vaseline.
In my future ‘things’ I am using a silicon spray… Not sufficiently used for a correct feedback for the moment…
Previous try… Innocent cap.
I am very impressed how the downward surface has a smooth finish using a silicon mould :).If you find a way to pressurize and cool the mold quickly. you may get way more better results.
Silicon is not designed to work with these plastics at first place, but it’s a viable option if it works under specific conditions.
Keep up the good work 🙂
Ha ! enfin ton retour !
–To pressurize… Seems not possible for my actual silicon mould.
–To cool down quickly… Why not… but what will be the advantage? Less deformation?
The smooth finishing is a thing easy to have when the bubbles are avoid 😎
Other disadvantage of silicon mould is its life time… You could not do a serie production. The temperature destroy them little by little…
I will publish other tries soon.
Good job!!!and good idea!the plastics letters are good for the kids:D i will try to make the mold with my cnc and i let you know!
You bought it only for precious plastic?
To do mould?
Hope I can see it myself this summer 🤤
