  2. Draft Angles:
    • Incorporating draft angles into the housing design is essential for easy ejection of the part from the mold. Draft angles allow for smooth removal of the housing from the die, reducing the risk of damage or sticking.
    • The specific draft angle required depends on the complexity of the housing and the characteristics of the mold. Typically, draft angles of 1-3 degrees are recommended.
  3. Ribs and Fillets:
    • Ribs and fillets are structural features that can enhance the housing’s strength and rigidity.
    • Ribs provide additional support and stiffness to the housing, helping to reduce deflection and increase overall structural integrity.
    • Fillets, which are rounded transitions between surfaces, help distribute stress and reduce stress concentration points, minimizing the risk of cracks or failures.
  4. Parting Lines:
    • Consider the placement of parting lines, which are the areas where the two halves of the mold meet. Ideally, parting lines should be located where they have the least impact on the housing’s appearance and functionality.
    • Minimize the complexity and number of parting lines to simplify the mold design and reduce the chances of flashing or other surface defects.
  5. Ejector Pins:
    • Ejector pins are used to push the housing out of the mold once it solidifies.
    • Proper placement and design of ejector pins are critical to avoid interfering with the housing’s features or causing damage during ejection.
    • Careful consideration should be given to the number, size, and location of ejector pins to ensure smooth and damage-free ejection.
  6. Gate and Runner Design:
    • Gates and runners control the flow of molten aluminum into the mold cavity.
    • Optimal gate and runner design enable proper filling of the mold, minimizing turbulence and the formation of defects.
