Aluminum Die Cast Parts Manufacturer In China

Table of Contents

Aluminum is the most abundant metallic element in the earth’s crust and has a silvery or dull grey appearance. It has good ductility, flexibility, electrical conductivity and durability. Aluminium is an ideal die-casting alloy material because of its excellent corrosion resistance, mechanical properties, and high thermal and electrical conductivity. This lightweight metal has good plasticity, is easy to process into various shapes, and is especially suitable for die-casting manufacturing complex parts structures.

Advantages of Aluminum Die Casting

  • -Lightweight Design: Aluminum is a lightweight metal, and aluminum die casting products are lighter than other metals, helping to reduce overall product weight for applications requiring lightweight and high strength, such as automotive and aerospace.
  • -Complex shapes: Aluminum die casting allows for the production of complex, sophisticated parts, enabling designers to achieve more innovative and complex product designs that improve product performance and functionality.
  • -High Strength: Aluminum die casting products have excellent strength and abrasion resistance, making them suitable for engineering applications requiring high strength and ensuring excellent performance in a variety of environments.
  • -Good thermal conductivity: Aluminum has good thermal conductivity, which helps to dissipate heat quickly, so aluminum die casting is widely used in electronic equipment and automobile engines and other fields that require efficient heat dissipation.
  • -Cost-effective: Aluminum die casting can achieve mass production, and the production process is relatively simple, so as to improve production efficiency and reduce production costs.
  • -Environmental protection: Aluminum is recyclable metal, aluminum die casting products have good sustainability, help reduce resource waste and environmental pollution.

Aluminum Die casting Process

  1. Mold design and manufacture: First, develop a suitable mould program according to the product design requirements. Then, manufacture the mold that can withstand high pressure to ensure accuracy and durability.
  2. Aluminum Alloy Melting: The aluminum alloy is heated to a liquid state in a furnace, usually with high purity aluminum blocks and alloying elements to ensure the uniformity and quality of the alloy.
  3. Injection Molding: A high-pressure injection machine injects The molten aluminium alloy into a pre-designed mold chamber. The high pressure ensures that the aluminum alloy fully fills the mold, creating a precise and dense product.
  4. Cooling and Curing: In the mold, the aluminum alloy is rapidly cooled and cured to form the desired shape of the part.
  5. Mould Opening and Cleaning: Once the aluminium alloy is cured, the mould is opened, and the finished product is removed. The finished product is then trimmed, deburred and cleaned to ensure that the final product meets the design requirements.
  6. Inspection and Quality Control: The finished product is strictly inspected, including dimensions, surface quality, etc., to ensure that the product meets the standards. Through quality control, eliminate defects and improve the quality of products.

Applications of Aluminum Die Casting

  • Automotive industry: Used in the manufacture of engine parts, transmission systems, chassis components, etc., to reduce the weight of the car and improve fuel efficiency.
  • Electronic industry: producing shells, radiators, and other electronic equipment components, using aluminium thermal conductivity to protect the equipment and allow it to work efficiently.
  • Aerospace: manufacturing aircraft parts, such as aircraft engine shells and structural components, to meet lightweight and high strength requirements.
  • Communication equipment: production of antennas, shells and other components to ensure the stability and efficient operation of communication equipment.
  • Medical devices: used to manufacture medical equipment shells, brackets, etc., to meet the requirements of medical equipment on lightweight and corrosion resistance.

1. What is the wall thickness requirement of aluminum alloy die casting?

The aluminum alloy die casting wall is not suitable for being too thin and prone to undercasting, cold segregation and other problems. In the usual conditions of use, the wall thickness is unsuitable for more than 4-5mm.

2. What is the appropriate temperature for aluminum alloy die casting?

The appropriate temperature range for aluminum alloy die casting is usually between 600℃ and 700℃. This temperature range ensures that the alloy achieves sufficient fluidity and lubricity while reducing the aluminium liquid’s oxidation possibility.

3. How do you control the temperature to get the best results?

  • Control furnace temperature: In the process of aluminum alloy die casting, the temperature of the furnace must be controlled to keep the temperature of the aluminum liquid in the correct range.
  • Control mold temperature: The temperature of the mold is crucial to the forming effect. After the liquid aluminum is injected, if the mold temperature is too high, it is easy to form bubble holes and uneven surfaces. If the mold temperature is too low, the liquid aluminum may condense, resulting in die casting sticking or damage.
