Die Casting Garden Lamp Manufacturing
When you look at a die casting garden lamp, you see a product shaped by a careful and advanced manufacturing process. Each step in aluminum die casting helps create a lamp that stands up to harsh weather and lasts for years. Let’s explore how this process works and why it matters for durability and weatherproofing.
Die Cassing Mold Design
The first step in manufacturing a die casting garden lamp is designing the mold. You start with a detailed plan for the lamp’s shape and features. Engineers use custom aluminum die casting to create precision molds from hardened steel. These molds have two halves: the cavity and the core.
- Uniform wall thickness in the mold keeps the lamp strong and prevents weak spots.
- Draft angles help you remove the lamp from the mold without damage.
- Ribs inside the mold add strength and stiffness without making the lamp heavy.
- Using corrosion-resistant aluminum alloys, such as 4420 or 4600, ensures the lamp can handle rain, snow, and sun.
- The mold’s design also helps the lamp cool evenly, which stops cracks and warping.
Tip: A well-designed mold means your lamp will have a seamless, weatherproof body that keeps water and dust out.
Metal Injection
Next, you move to the metal injection stage. Here, you melt aluminum at high temperatures, usually between 660°C and 750°C. The molten aluminum flows smoothly because of its excellent fluidity. You inject this metal into the mold using very high pressure—sometimes up to 25,000 psi. This step is key in the die casting process.
- Aluminum is the top choice for die casting garden lamp manufacturing. It is lightweight, strong, and resists rust.
- Sometimes, manufacturers use magnesium or zinc for special parts, but aluminum die casting is most common.
- The high-pressure injection fills every part of the mold, so the lamp has no gaps or weak spots.
This step creates a seamless lamp body. You get a product that keeps out moisture and stands up to outdoor use.
Cooling and Trimming
After injection, the lamp needs to cool and harden. Controlled cooling is very important in aluminum die casting. If the lamp cools too fast or unevenly, it can crack or warp.
- Cooling channels in the mold help the lamp solidify evenly.
- Special fixtures hold the lamp steady as it cools, keeping its shape perfect.
- Once the lamp is solid, you remove it from the mold using ejector pins.
- Trimming comes next. You cut away extra metal, called flash, and smooth the edges.
This careful cooling and trimming process keeps your die casting garden lamp strong and stable. It prevents problems like cracks, warping, or leaks that could let water inside.
Assembly and Testing
Now, you assemble the lamp. You add LED housings, wiring, lenses, and gaskets. Each part fits perfectly because of the precise aluminum die casting process.
- You use weatherproof connectors for the wiring to protect against rain and dust.
- During assembly, you check every part for quality and fit.
Testing is the final step in manufacturing. Each die casting garden lamp goes through:
- Electrical testing to make sure the lamp works safely.
- Waterproofing checks to confirm no water can get inside.
- Visual inspection for any defects or damage.
Quality control happens at every stage. You make sure each lamp meets strict standards for durability and weatherproofing. Many lamps also earn certifications like UL or IP65, which prove they can handle outdoor conditions.
Note: These steps in aluminum die casting and metal die casting make sure your lamp will shine bright and stay strong, even in tough weather.
