What is the alloy small lot casting method |
|
The die-cast very economically about the product with much
quantity because it is the casting law which does the cast about which the casting
skin is excellent in the high-precision in the mass production and is highly productive.
However, to cast hot fusion metal, being high-speed and being
high-pressure, the type precision and the durability are necessary, the term of
construction work hangs long, necessitously, the amount of money, too, has been
on high and it is unsuitable for the small job-lot manufacturing. Therefore, it
is a small lot casting law that was made to be able to cast a cast like the die-cast
simply for the small job-lot manufacturing. |

The good point |
|
| a) |
A shape, size precision, a thickness, casting skin like the
die-cast are gotten. |
| b) |
The curve for which it is difficult to be composed by the machine
processing, a deep ditch are gotten. |
| c) |
The manufacturing period is short. |
| d) |
Even if the design change and so on occur, by the correction
of the solid model, it is possible to support quickly. |

The main material |
|
| a) |
Aluminum alloy |
| b) |
Zinc alloy |
| c) |
Magnesium alloy |
| d) |
Copper alloy |

The comparison with the small job-lot manufacturing
process and with the other method of construction |
|
| The solid model manufacturing |
(The decompressed work) |
|
The sand mold casting:
The wooden form manufacturing -- The sand charging -- It removes a wooden form.--
It adjusts a type.-- The casting --The completion --The machine processing
The mold casting:
The mold engraving ----- The heat-treatment----------- It adjusts a type-----
The casting----The completion----- The machine processing
Lost wax:
The mold manufacturing for the model- The wax modeling -- It assembles a tree.--
It takes wax.-- The casting --The completion-- The machine processing

There are achievements in the car relation and the parts such
as the construction machine. |
