Leading Squeeze Casting Manufacturer in china
High strength, high air tightness, no casting defects
squeeze casting ------ Say NO to Aluminum Casting Defects
Squeeze casting, also known as liquid metal forging, is the latest aluminum casting process that combines the benefits of both die casting and forging. This process enables the rapid mass production of precision components with complex shapes, while also delivering the superior mechanical properties typical of forging parts.
Sanon Casting is a China-based aluminum squeeze casting manufacturer with patented technology and over 6 years of experience. We have successfully produced high-performance squeeze cast parts for industries like automotive, EV, trucks, motorcycles, medical, and power, etc.
-
Say NO to Casting Porosity
Squeeze casting can eliminate internal pores or shrinkage defects in castings, allowing you to achieve aluminum components free of porosity.
-
Say NO to leakage
Squeeze-cast parts feature a dense internal structure with no porosity, ensuring excellent airtightness. Min 0.7MPa
-
Say NO to Low Strength
The mechanical properties of squeeze casting parts are comparable to those of forging components.
-
Say NO to Expensive CNC Machining
Squeeze casting enables the production of high-strength, "near-to-shape" parts, significantly reducing machining allowances compared to the forging process. This allows you to achieve high performance while greatly lowering CNC machining costs.

Everything You Should Know About Squeeze Casting
01. Squeeze casting types
Direct Squeeze Casting
Process: Molten metal is poured directly into an open die cavity, and a punch applies pressure during solidification. This process has many limitations and can’t cast parts with complex structures.
Indirect Squeeze Casting
Process: Molten metal is injected from the bottom into a closed mold, and pressure is applied during the solidification process to forcefully eliminate internal porosity in the casting, resulting in higher-density parts.
Our process is indirect squeeze casting, which can produce aluminum parts with complex structures and high performance. The image on the right shows our self-developed and patented 400T indirect squeeze casting machine.

02. Squeeze casting features
1. Low Speed Filling
Unlike high pressure die casting, in squeeze casting, molten aluminum fills the die at a lower rate, which prevents air from being trapped in the liquid metal during the filling process.
Meanwhile the mold’s exhaust system can smoothly remove the air in the mold.
Aluminum casting parts without porosity are what we all want!
2. High Pressure Molding
Once the mold is filled, the pressure on the molten aluminum increases to over 100 MPa and pressure is maintained to feed the casting to compensate for shrinkage until the casting solidifies.
This further removes air from the liquid metal and refines the internal organization, giving the part a higher density.
3. Parts can be T6 Heat Treated and Welded
The heat treatment options available for squeeze casting are T4, T5, and T6. After heat treatment, the parts will have higher tensile strength, yield strength, hardness, wear resistance, air tightness, etc.
At the same time, the squeeze casting parts can be welded to better meet the actual needs.
4. Superior Performance
Tensile strength: 280-320MPa
Yield strength: 220-260MPa
Elongation: 7%-11%
Hardness: 80-110Hb
Air tightness: ≥0.5MPa, no leakage.
If your parts require high performance and high air tightness, please feel free to contact us and we will surprise you!
03. How Can Squeeze Casting Help Us?
Eliminate Casting Defects
The squeeze casting process allows you to get rid of common aluminum casting defects such as shrinkage, porosity, cold shut, cracks, etc., so that your aluminum castings will have the same quality as forgings and the same smooth surface as CNC parts.
Squeeze casting will provide you with a reliable solution for your demanding aluminum castings, especially thick-walled parts.
Cost-Effective
By replacing forging or CNC machining with squeeze casting, you will significantly reduce the cost of manufacturing your parts.
In addition, aluminum squeeze castings with high mechanical properties can also replace steel or iron parts. This helps reduce the weight and cost of the part.

05. Squeeze Casting VS Die Casting VS Forging

Squeeze Casting Advantages
1. Low porosity and shrinkage.
2. High density inside and smoother surface.
3. Parts can be heat treated and welded.
4. Higher mechanical properties.
5. High efficiency and small machining allowance.
6. High air tightness, pressure resistance ≥0.5MPa, no leakage.

Squeeze Casting VS Die casting
Lower porosity and better mechanical properties.
Compared with aluminum die casting parts, squeeze cast parts do not have the common defects of porosity or shrinkage, and their mechanical properties are much higher than die casting parts, which can be close to the standard of forging parts.
Squeeze casting products can be T4-T6 heat treatment to further improve mechanical properties such as tensile strength, yield strength, hardness and elongation.
Precess | Material | Tensile Strength | Yield Strength | Elongation | Hardness | Air Tightness |
---|---|---|---|---|---|---|
Die Casting | ADC12 | 140-160MPa | 80-90MPa | 1%-2% | 70-80Hb | 0 |
Squeeze Casting(after T6) | A356.2 | 270-300MPa | 220-240MPa | 7%-9% | 85-100Hb | ≥0.5MPa |

Squeeze Casting VS Forging
Less machining allowance and lower cost.
The properties of squeeze casting process are close to those of forging, but it is possible to complete parts with more complex shapes and to mold them in a single operation. Squeeze casting generally does not require machining or only a small amount of machining, thus saving a lot of time and machining costs.
