KYLT Aluminum Alloy Die Casting Working Process
The die casting process at KYLT typically follows a high-pressure injection method to produce precise aluminum parts. The workflow consists of the following key stages:
1. Die Preparation and Clamping
- Cleaning & Lubrication: The hardened steel die (mold) is cleaned and sprayed with a lubricant. This helps control the temperature of the die and facilitates the easy removal of the casting.
- Clamping: The two halves of the die are securely closed and clamped together by the die casting machine. High pressure is applied to ensure the die remains tightly closed during injection.
2. Melting and Injection
- Melting: Aluminum alloy ingots are melted in a furnace to a specific temperature (usually between 600°C and 700°C) to achieve the proper fluidity.
- Injection: Molten aluminum is ladled into the shot chamber. A hydraulically driven plunger pushes the molten metal into the die cavity at high speed and under high pressure (typically ranging from 10 to 175 MPa).
3. Cooling and Solidification
- Once the cavity is filled, the metal is held under pressure while it cools and solidifies.
- The cooling time depends on the size and thickness of the part. This phase ensures the casting takes the exact shape of the die.
4. Ejection
- After the solidification time has elapsed, the clamping unit opens the die.
