Sand AAC line 2015 new fly ash AAC line 

1. Fly ash sand AAC line simple introduce 

AAC block (light brick ) is the light and porous buidling material. It has 
Light keeping temperature cant burn and other advantages. It can be made into many kinds 
Of bricks(for example: 600X200X100, 80X80X180, 240X115X53, 600X200X125), they could 
Be used industry building and common building. They are more and more popular in the 
World. In the future, they will replace the Clay brick completely. 

2. Fly ash sand AAC line common conception 

Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3, 600kg/m3 
, 700kg/m3. It has not the big grain, main use silicon material (for example: Coal ash, sand, 
Stone dust and others ), through making the material small for example sand, they can be 
Used directly if has enough degree of small (for example coal ash. Mixing calcium material 
Lime cement water to a special slop, then add the aluminum dust and the additive. Make the 
Aluminum dust and the special slop have a Chemical reflect. Then produce Hydrogen to make 
The concrete slop to expanding or swell, foam. Next, put them into the curing room to 
Concreting cutting steaming curing, last, there will bacome the light brick, the porous rate 
Is 70-80%. 

3. Fly ash sand AAC line advantage 
1)light weight 
Areated concrete density is usually 400-700kg/m3, (according the market in produce ), same as 
1/3 of clay brick and 1/5 common concrete. So use the Light brick can reduce the weight of 
The build more, and also reduce the beam of roof and pillar press best. Then you can see, it 
Can save the material and cost, it also fighting shaking. 
2)keeping temperature 
It has many are porous, the delivery hearting coefficient is 0.9-0.22W/(mk), the same as 1/4 
Or 1/5 of clay brick, so it is best materials now in the world.

Gravity Casting Parts

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

  1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
  2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
  3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

  • Good dimensional accuracy
  • Smoother cast surface finish than sand casting
  • Improved mechanical properties compared to sand casting
  • Thinner walls can be cast compared to sand casting
  • Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
  • Steel pins and inserts can be cast in to the part
  • Faster production times compared to other processes.
  • Once the tolling is proven, the product quality is very repeatable.
  • Outsourced Tooling setup costs can be lower than sand casting.
