Contacting about aluminum castings
 

Rich knowledge and latest equipments

Aluminum castings are classified into die casting and sand or plaster casting.
And die casting are classified into pressure die casting and gravity die casting.
Pressure die casting is suitable for thin-walled and mass production, Gravity die casting is suitable for wall thickness shape.
Especially, there are several ways with superior features in pressure die casting.
We can propose the best way to your problems and issues by our rich knowledge and latest equipments.

Pressure die casting products

 
Aluminum die casting product is produced by filling a molten aluminum into a metal mold cavity under the high pressure.
Because die casting use a metal mold, it is suitable for the mass production which can make the excellent casting in dimensional accuracy and surface in a short period of time.
This method enable us to produce products efficiently in complex shapes, lignht weight or high strength.
 

Pore Free Die Casting

The gas in the cavity replaced by O2 can make the no blowholes material by chemical reaction with aluminum.
Because this method controls the gas content of the aluminum compared to general die casting, its product can be T6 heat treatment.
 
Pore Free Die Casting

Materials

We use following materials to our pressure die casting products.
Material Name Standard Remarks
ADC12 JIS H 5302 Mechanical properties, machinability, good castability
NH41(ANDC13) HiSilicon Abrasion resistance, good machinability

Gravity die casting products

 
Gravity die casting product is produced by filling molten aluminum into the metal mold cavity by gravity.
By gravity filling, it is less air entrainment(pore) compared with the die-casting.
The products have the feature which can be heat treatment and welding easily.
 

Gravity die casting with the disintegratable core

The disintegratable core is set in the cavity, before the aluminum injection by the gravity.
After the aluminum solidification, it is possible to make the hollow product by removing of the core.

Sand / Plaster mold casting and Prototype casting

 
Sand mold / plaster mold casting is produced by filling the sand mold / plaster mold a molten aluminum by gravity.
Because the sand / plaster casting method does not require the metal mold, it is advantageous in delivery time and cost compared with die casting , but one sand / plaster mold is required by one casting .

Fast prototype casting with 3D printing

We introduce PLASTER STACK MOLD 3D PRINTERS mainly for our model production of aluminum castings.
With 3D CAD data or solid data, it is possible for us to manufacture 3D models of plaster model printings or casting production by printed aluminum plaster castings in a short period of time.

Quality inspections

 
We also make every effort to provide the best quality aluminum products by other ways of inspections than this page.
 

Component analysis

We conduct the material component check, which is essential to procedure the high quality aluminum products, when we melt aluminum.

Mold filling simulation

We design the best casting plan by simulating the mold filling in advance of actual production.
We examine the effective and low-cost mold design using 3-dimensions data and mold filling simulation before the actual mold production.

Dimensional check

We have 2 types of measuring inspections.
One is the checking product size by brandnew mold,
the other is checking the unevenness under the mass-production.
We check the dimensions of mold and product using coordinate measuring machine.
