Squeeze casting, also known as liquid forging, is a combination of die casting and forging, with the advantages of both. It is typically used to produce near-net-shape, high-strength, high-airtight, high-wear-resistant, thick-walled, heat-treatable parts. It is a very cost-effective casting process!
Liquid metal is injected into the mold cavity at low speed to completely fill the cavity and reduce air entrainment. High pressure is then applied to forcefully eliminate shrinkage and porosity created during solidification of the liquid metal, so as to obtain squeeze casting parts free of casting defects.
Currently, the squeeze casting materials are mainly die-cast aluminum alloys, such as A356, ZL101, ZL104, AlSi9Cu3 and so on. Therefore, if you want to have aluminum parts with higher mechanical properties, the squeeze casting process will be a right choice.
Squeeze casting is suitable for parts with complex shapes and high performance requirements!
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.
Because squeeze cast parts are virtually free of casting defects, they have excellent properties：
Tensile strength: 260-300MPa
Yield strength: 220-260MPa
Elongation: 7%-11%
Hardness: 85-110Hb
Air tightness: ≥0.5MPa, no leakage.
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.
| Precess | Material | Tensile Strength | Yield Strength | Elongation | Hardness | Air Tightness |
|---|---|---|---|---|---|---|
| Aluminum Die Casting | ADC12 | 140-160MPa | 80-90MPa | 1%-2% | 70-80Hb | 0 |
| Aluminum Squeeze Casting | A356.2 | 260-300MPa | 220-260MPa | 7%-9% | 85-110Hb | ≥0.5MPa |
| Aluminum Squeeze Casting | AlSi9Cu3 | 350-370MPa | 260-280MPa | 2%-3% | 110-125Hb | ≥0.5MPa |
| Aluminum Squeeze Casting | Latest Material | 350-370MPa | 260-270MPa | 11%-13% | 110-125Hb | ≥0.5MPa |
Squeeze casting is the end of common aluminum die casting defects.

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!
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.
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.
Tensile strength: 260-300MPa
Yield strength: 220-260MPa
Elongation: 7%-11%
Hardness: 80-110Hb
Air tightness: ≥0.5MPa, no leakage.

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 |
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.

Squeeze casting process is divided into direct squeeze casting and indirect squeeze casting. Direct squeeze casting has a lot of limitations, it can not cast the parts with complex structure.
The machine in the picture on the right is our self-developed horizontal indirect squeeze casting machine. We have spent a lot of time, effort, people and money to develop a better performing squeeze casting machine. After numerous attempts, we finally succeeded and have developed 4 units.
The parts produced by these squeeze casting machines have a very smooth surface, high mechanical properties (similar to the forging process) and low machining allowances.
The parts can be produced regardless of complex or simple shapes, and the production efficiency is very high.
