Love Casting

Im asking this cuz i know that some engine with aliminium in it either the intake , block , heads have a tendancy to wrap , leak, and be less durable overall than the good old chevy small block for exemple. So iz it just coincidence or iz cast iron really better than aluminium even if they say they use it to lower the weight of the car. For exmple i think a gm 3.8 3800 is all cast iron (intake block) and i know it has a better reputation than a 3.1 thx

the only reason for the heads warping. Is that the 3.1 had a iron block and aluminum heads that have different expansion rates and at the time was still a somewhat new technology. Any engine with aluminum/iron can have that problem. But engineering is alot better now then then. The 3.8 actually has a plastic intake that had a tendency to leak but they came up with a better replacement version that keeps that from happening. I guess there was some sort of lawsuit against gm and the coolent they use dexcool that some people said made the intake deteriorate.

Backyard aluminum casting at home. Melting aluminum in a charcoal foundry and pouring it into a greensand mold. The little flare up at the end was easily contained and nothing was damaged except the wooden box.

think i used brusselse aarde
no i used bindolzand (rode kneedbare zand / red sticky sand)
from http://www.hazelaar.nl 25kilo = 44 euro

i do not understand the price i payed for the scrap aluminium
on the londen metal exchange LME
the price is 2700 usdollar per 1000 kilo
2.7 dollar per kilo
2.7 U.S. dollars = 1.82679296 Euros
1.82 euro * 22 kilo = 40.18euro and i paid 25 euro
could get sleeping rich if i where a scrap metal dealer

An average aluminium can (without its contents)
weighed 16.55 grams in 1992.
By 2005 the aluminium can weighed about 14.7 grams.
thats 68 / 69 cans in a kilo
aluminium can price is 1.5 usd a kilo or 1500usd per ton

so this skull is aprox 345 cans

Aluminium has a melting point of 660°C
compared with 1540°C for iron

If all the aluminium cans sold in the UK were recycled for cash it would raise more than £30 million for collectors.
Setting up an aluminium can recycling scheme is a great way to raise funds for a charity or good cause without having to ask for donations.

Aluminium Die Casting industry

It is a stiffness problem. You need to know or assume the injection pressure, know the area of the slide, and the amount of deflection allowed at the face of the slide. That will give you the forces and the deflection allowed – or stiffness. From there determine the locking force and mould base stiffness needed to provide more stiffness than you calculated from the above. If the base and locking system are not stiff enough, the part will not be within tolerance.
