What Is Squeeze Die Casting?
Squeeze Die Casting (also known as Squeeze Casting) is a advanced casting technology that bridges the gap between High-Pressure Die Casting and Low-Pressure Die Casting. Unlike traditional methods, it uses controlled pressure during the solidification process to eliminate porosity and improve material density.
A quick process overview reveals its core value: molten metal is injected into a die, then a mechanical squeeze force (ranging from 10 to 150 MPa) is applied as the metal cools. This extra pressure ensures the metal fills every detail of the die, resulting in components with superior strength and dimensional accuracy. Table 1 compares it to other casting methods:
| Casting Method | Pressure Range | Porosity Level | Strength (Al Alloy) | Ideal Use Cases |
| Squeeze Die Casting | 10–150 MPa | Very Low (<1%) | 300–450 MPa | Structural parts, medical devices |
| High-Pressure Die Casting | 50–150 MPa | Medium (2–5%) | 250–350 MPa | Consumer electronics, small components |
| Low-Pressure Die Casting | 0.1–1 MPa | Low (1–2%) | 280–380 MPa | Large automotive parts (e.g., wheels) |

The Squeeze Die Casting Process: Step-by-Step
The Squeeze Die Casting Process follows a streamlined process flow designed for consistency and efficiency. Each step is optimized to minimize cycle time (typically 60–180 seconds per part) while maximizing quality.
- Injection: Molten alloy (heated to 600–750°C for aluminum) is injected into a preheated die (150–250°C) at low speed (0.5–2 m/s).
- Squeeze: Once the die is filled, a hydraulic press applies pressure (20–120 MPa) to the molten metal. This step eliminates air bubbles and ensures full die cavity filling.
- Cooling: The metal solidifies under pressure for 10–30 seconds. Coolant channels in the die speed up this process while preventing warping.
Ejection: The die opens, and robotic arms (for automation) remove the finished part. Post-ejection, excess material (flash) is trimmed for precision.
Materials Used in Squeeze Die Casting
Choosing the right materials is critical to achieving optimal part performance. At Yigu Technology, we work with a range of high-performance alloys, each selected for its unique properties.

Advantages of Squeeze Die Casting
The advantages of Squeeze Die Casting make it a top choice for industries where performance and cost matter.
- High Strength: Parts have 15–30% higher tensile strength than high-pressure die cast components (e.g., aluminum parts reach 400+ MPa).
- Lightweight: Alloys like aluminum and magnesium reduce part weight by 30–50% compared to steel, improving fuel efficiency in vehicles.
- Reduced Porosity: Pressure during solidification lowers porosity to <1%, eliminating the need for secondary sealing processes.
