Gravity die casting (GDC) is a permanent mold casting process widely used to produce high-integrity aluminum alloy components across automotive, electronic, medical, and industrial sectors. The process delivers dense, dimensionally stable parts with good mechanical strength and complex geometry capability, making it suitable for structural and functional metal components.
| Industry | Common Products |

| Consumer Goods | Cookware, household appliance components, lighting fixtures, structural furniture parts |
Key Takeaways
- Gravity die casting produces high-density, structurally sound metal components applicable to automotive, electronic, medical, and industrial equipment industries.
- The process supports complex geometric forming with consistent dimensional repeatability and improved material utilization compared with traditional sand casting.
- In automotive manufacturing, gravity die casting produces robust structural components such as engine blocks and brake calipers for reliable mechanical performance.
- For electronic and telecommunication devices, GDC provides rigid protective housings and high-performance heat sinks for structural stability and thermal management.
Gravity Die Casting in Automotive Components
Gravity die casting is important for making car parts. Many parts in cars are made this way. This method helps make metal parts that are strong and exact.
Engine Blocks
Engine blocks are a key part of every car. They hold the cylinders and other engine pieces. Gravity die casting makes engine blocks strong and accurate. It helps make shapes that are hard to create and keeps the quality the same. This method gives better strength and uses less material.
Cylinder Heads
Cylinder heads go on top of engine blocks. They cover the cylinders and help move air and fuel. Gravity die-cast cylinder heads feature low porosity, stable tensile strength, and consistent elongation properties, meeting standard automotive engine operating pressure requirements. This way, you get metal parts that last and work well.
Brake Calipers
Brake calipers are commonly produced by gravity die casting because the process provides better structural integrity and lower porosity than many high-pressure casting methods. Gravity die casting makes brake calipers with tight grains and smooth surfaces. You get parts that fit well and are always the same. This method keeps holes low and is good for making many parts.
Wheel Hubs
Wheel hubs join the wheels to the car. Gravity die casting makes wheel hubs stronger and helps them last longer. These parts are light but still strong. This method lets you make hard shapes fast.
| Property | Gravity Die Casting | Sand Casting |
|---|---|---|
| Density (g/cm³) | 2.68–2.70 | 2.65–2.68 |
| Tensile Strength (MPa) | 240–310 | Lower than 240 |
| Fatigue Resistance | 2–3× better | Lower |
| Elongation (%) | 3–10% | Lower |
You can count on gravity die casting for car parts because it gives strength, accuracy, and trust.
Die Casting for Electronics and Telecommunications
Electronics and telecommunications need parts that are strong and last long. Many products in these areas use die casting.
Housings and Enclosures
Many electronic devices have die-cast housings and enclosures. These parts keep circuits safe from dust, water, and bumps. Gravity die casting helps make housings with tight shapes and smooth sides. This way, metal parts fit together just right. You can trust these enclosures to protect electronics, even in hard places.
MORELUX manufactures specialized housings for electronic and telecommunications equipment.Their products follow strict world rules. You get good protection for your devices, from small connectors to big control boxes.
Heat Sinks
Heat sinks help keep electronics cool. Good heat control stops devices from getting too hot. Die casting lets you make heat sinks with tricky fins and shapes. These designs move heat away from chips and circuits fast.
Aluminum is a top metal for heat sinks because it moves heat well. Gravity die casting makes light and good heat sinks for computers, routers, and telecom stations. Die casting makes sure every heat sink works the same, so you get steady results.
- Die-cast housings protect electronics and help with heat.
- Aluminum heat sinks from die casting keep devices cool and safe.
- Careful die casting makes sure connectors and hardware work every time.
Gravity Die Casting in Medical Equipment
Gravity die casting is important for making medical parts. Medical devices must last, look nice, and work well. This process helps make strong metal parts for hospitals.
Device Housings
Device housings are found in many medical machines. They protect inside parts from dust and water. Gravity die casting uses metal molds again and again. This makes smooth surfaces and exact shapes. You get housings with tight fits and nice finishes. You can pick different coatings or plating for your needs.
- Complex housings with net shapes
- Surfaces that resist damage and rust
- Same quality for many parts
Note: Gravity die casting lets you add heat sinks to housings. This helps control heat in medical equipment.
Precision Components
Medical equipment needs small, exact metal parts. Gravity die casting makes tiny designs with tight fits. You get parts that fit right and work well. This process is good for connectors, brackets, and frames.
- Keeps tight fits for accuracy
- Makes tricky shapes for hard devices
- Good for making lots of parts cheaply
MORELUX checks every part with strict controls. Their factory follows tough rules and gets certifications.
Industrial Parts from Gravity Die Casting
Factories use gravity die casting to make strong parts. This process is used for many machine products. You see it in pumps and valves too. If you buy or sell these parts, you want them to last. Gravity die casting helps make parts that work well in hard jobs.
Pump Parts
Pump parts must be tough and used a lot. You find them in water, oil, and chemical plants. Gravity die casting makes pump housings, impellers, and covers. These parts have smooth sides and fit together well. Metal molds help make the shapes exact. These parts do not wear out fast and last a long time.
- Pump valve parts
- Machinery parts
- Heat sink components
Valve Bodies
Valve bodies help control liquids and gases. They must be strong and not leak. Gravity die casting makes valve bodies dense and solid. This means they do not crack or leak easily. The process lets you make tricky shapes for special valves.
Gravity die casting makes valve bodies work better. The parts are the right size and have smooth sides. This helps valves last longer, even with heavy use.
