aluminium plate from casting

[Il marangon]

Hello

I have to make a rather large aluminum mold (1800 x 1200 h80) and my supplier made me the proposal of a cast aluminium plate (peralluman) instead of drawn.

Now I am not mechanical and my knowledge is practically 0; I wanted to know, what differences are there between one plate and the other?

I have to work this piece with minimal oil air lubrication and by previous experiences castings tend to knead a lot of tools

hello marangon
we talk about two different products
you have to understand what you need
If you need to get a model for foundry on which you can get food bags it is good the aluminum casting in any quality'
or as I read you must make a mold and in case you illuminate for which materials to print
the aluminium profile
in the possible if you specify what you have to do I will be more precise
When it comes to processing, it's hard for alumni to knead the tool.
then emulsion to fly
and above all the choice of the cutter
you have to choose a very wide helical type so that the chip can escape easily
typically use cutters with three helids running t
in the roughing it is better to use a puzzle
with which you can pass in removal of considerable importance
in addition to emulsion if the cn also has the option of the temporary oil spray also uses that
for the rest I expect your feedback
Thank you very much

I have to make an or mold to form felt, that of car hairs to understand

I've already had a fight with the aluminum kneading but some alloys you can also work dry. putroppo on the machine that I have no chance to lubricate abundantly, I only have an oil air sprayer

you have to make a mold for setup
what is used in the interior coating car industry
in that type of mold it is used to have an internal coil for heating the mold
if you make the model for foundry you can insert pipes in the fusion
avoid doing a subsequent mechanical operation to create a circuit
you can make a model with controlled weigher 20/25 mm and save a lot of weight so you just need the mold mantle
precise is a disused technology not because it is not valid
But because today it has become complicated to find people who can do this kind of work.
also you need a "suitable" foundry
as the mold "matrix and punch" are unique pieces you can also make models of expanded polystyrene and save on the equipment
If you have "light" cnc, it's obvious you have to watch the car.
eliminndo the accumulation of chips with the air blow
even if by experience on these types of molds there are not very deep pockets then accumulation of chips and relative
for me if you can build a well-made model and you have a faultless fusion go with the fuss saves a lot of money:wink:
Thank you very much

we also rated the fusion option but for the mold that I have to do is not worth, the max thickness is 80mm and the customer did not tell me about cooling system

then for a matter of times we opted for the plate

but what I don't understand, what differences are between drawn plate and melted plate like I proposed? definitely in the price (no less casting) but there must be a reason for the lower price. . .

the "pane" of cast aluminium costs today around 3.00€ per kg
(ii)
you have to add minimum 3-3.50-4 € transformation

for the peralluman plate (the quality that costs less) drawn we are intrno to 5.60€ per kg

it is possible that there are other commercial motives so that you can give yourself a fuse at a lower price of the plot
Thank you very much
