Differential Pressure Casting Technology
TANIDA has been operating its differential pressure casting process for many years. This process is effective to aluminum alloy and magnesium alloy, substantially reducing casting defects in sand castings. Castings produced with this unique method will have high fatigue strength and airtightness, without any downstream processes required such as Hot Isostatic Pressing (HIP) Process. This process is also suitable for thin-wall, complex castings, making it an innovative casting process like no other. TANIDA’s principle. It is all packaged in differential pressure casting method.
ABOUT“Differential pressure casting technology”
New standards with differential pressure casting technology
The following explains the new standards introduced by differential pressure casting technology, that has achieved superior castability in comparison to the ordinary gravity cast and low pressure cast, by covering the sand mold and molten metal with chamber.
New Standards
1. high-quality casts that TANIDA is proud to offer
By controlling the solidification process during the casting procedure to occur in pressurized atmosphere using differential pressure casting technology, this increases the degree of solid solution of H2 gas in aluminum (utilizing physical phenomenon), allowing outgassing to be controlled. This also allows precise and sensitive control of pouring speed of molten metal going into the mold, removing unwanted variations in casting process while keeping excellent runnability that had never been made possible.
2. Outstanding improvements in efficiency
Any pressure conditions (pressurization / depressurization) can be made to initiate the best casting parameters ideal for the product configuration and forms. (Pressurization/max : +800 kPa / Depressurization/max : -100 kPa)
3. Complex shapes made simple
Casting in inert gas atmosphere, such as argon and nitrogen gas is also available. Improved fluidity by preventing oxidation of molten metal and also effective for enhancement of runnability on thin-wall, complex configurations. It is also suitable for casting of active metal such as Magnesium.
4. Stable process and quality
Mechanical process will eliminate the variations that may occur in “manual” operations.
This will result in and maintain superior quality, and provide consistency in casting.

New Standard 02
Sand layer 3D printer
For sand casting, wooden mold (resin mold) is a mandatory tool to generate sand mold. However, with some projects, time constrains may not allow us to create wooden mold. Our solution to this is by the make of sand mold, replacing the time consuming wooden method. We are right in the pursuit of whatever we can to achieve the shortest delivery time possible.
