EMI-Shielding Zinc Alloy Die Casting Parts 0.05-10mm Thickness

Product Definition

Die-castings are parts manufactured through die-casting technology. The specific process involves preparing a die-casting machine equipped with a casting mold, injecting molten metals such as copper, zinc, aluminum, or aluminum alloys into the feed inlet of the die-casting machine. Subsequently, under the pressure applied by the die-casting machine (usually in the range of 30 - 150MPa, and up to over 200MPa for some large and complex parts), the molten metal is pressed into the mold cavity. After cooling and solidification, parts that meet the shape and size requirements of the mold are produced. In different regions, die-castings are also referred to as die-cast parts, pressure castings, die-cast aluminum, die-cast zinc parts, die-cast copper parts, etc.

Product Characteristics

  1. Capability of Forming Complex Shapes: Due to the excellent fluidity (e.g., the fluidity of aluminum alloys at die-casting temperature can reach 30 - 80mm/s, and that of zinc alloys can reach 50 - 100mm/s) and plasticity of metals such as copper, zinc, aluminum, and aluminum alloys, and the fact that casting is performed in a pressurized die-casting machine, die-castings can be manufactured into various complex shapes. These include thin-walled structures with a minimum wall thickness of 0.5mm, micro-holes with a diameter of less than 1mm, and integrated structures with multiple chambers and ribs. This characteristic greatly expands the possibilities of product design and meets diverse application needs. For instance, structures that originally required 5 - 8 parts to be assembled can be integrally formed through die-casting technology, reducing assembly processes.
  1. High Precision and Surface Finish: Die-castings can achieve high precision and surface finish. The dimensional tolerance can usually be controlled within IT11 - IT13 grade, and some precision die-castings can even reach IT8 - IT10 grade. The surface roughness Ra value is generally between 1.6 - 6.3μm, which can directly meet assembly requirements without extensive machining. Taking aluminum alloy die-castings as an example, their flatness error can be controlled within 0.1mm per meter, and the cylindricity error does not exceed 0.05mm. This not only reduces the number of machining processes by 30% - 50% and saves more than 40% of machining time and costs but also reduces errors that may occur during the machining process, improving the stability of product quality.
  1. Material and Cost Advantages: High precision means that the casting allowance of metal materials can be controlled within 0.5 - 2mm. Compared with traditional casting processes (where the allowance is usually 3 - 5mm), the material utilization rate is increased by 20% - 30%, avoiding unnecessary material waste. At the same time, reducing the amount of machining can lower electricity consumption by more than 50% and labor costs by approximately 30%. In addition, copper, zinc, aluminum, and aluminum alloys themselves have excellent thermal conductivity (the thermal conductivity of aluminum alloys is about 120 - 200W/(m·K), which is 3 - 5 times that of cast iron), low specific gravity (the density of aluminum alloys is only 2.7g/cm³, approximately 1/3 of that of steel), and high machinability (the cutting speed can reach 100 - 500m/min). These properties give die-castings obvious competitive advantages in many fields, with the comprehensive production cost being 15% - 40% lower than that of traditional machined parts.

Application Fields

  1. Automotive Manufacturing Industry: Die-castings are widely used in automotive manufacturing, covering engine systems (such as engine blocks, cylinder heads, valve rockers, etc.), transmission systems (such as gearbox housings, gear chambers, etc.), chassis systems (such as suspension components, steering knuckles, etc.), and body structural parts (such as door frames, bumper frames, etc.). Taking automotive aluminum alloy die-castings as an example, the number of die-castings used in a single car can reach 50 - 100 pieces, accounting for 8% - 15% of the total weight of the car. By using die-castings, automobiles can achieve lightweight design. For every 100kg reduction in weight, the fuel consumption per 100 kilometers can be reduced by 0.3 - 0.6L, improving fuel economy while ensuring structural strength (the tensile strength of aluminum alloy die-castings can reach 200 - 400MPa) and safety.
  1. Electronic and Electrical Industry: In electronic and electrical products, die-castings are mainly used to manufacture various housings, brackets, and heat dissipation components. Examples include the housings of mobile phones, laptops, and tablets, as well as internal structural parts of televisions and air conditioners. Aluminum alloy and zinc alloy die-castings have good thermal conductivity (the thermal conductivity of zinc alloys is about 100 - 120W/(m·K)), electrical conductivity, and electromagnetic interference (EMI) shielding performance (the shielding effectiveness can reach 30 - 50dB), which can effectively protect internal electronic components and improve the performance and stability of products. Taking laptop housings as an example, the thickness of aluminum alloy die-cast housings can be controlled within 1 - 2mm, and their weight is only 1.2 - 1.5 times that of traditional plastic housings, while the impact resistance is increased by 2 - 3 times.
  1. Aerospace Field: The aerospace field has extremely strict requirements on the performance and quality of components. Magnesium alloy die-castings have been widely used in this field due to their advantages such as low density (about 1.8g/cm³, only 67% of that of aluminum alloys), high specific strength (the specific strength can reach 120 - 180MPa/(g/cm³)×10³), and good shock absorption performance (the damping coefficient is 2 - 5 times that of aluminum alloys). They are often used to manufacture aircraft cabin internal structural parts, seat frames, engine accessories, and lightweight structural parts of spacecraft. The number of magnesium alloy die-castings used in a single spacecraft can reach dozens of pieces, which helps to reduce the weight of the aircraft. For every 1kg reduction in weight, the launch cost of the spacecraft can be reduced by 10,000 - 20,000 US dollars, improving flight performance and energy efficiency.
  1. Medical Device Industry: With the development of the medical device industry, the requirements for the precision, surface quality, and biocompatibility of components are constantly increasing. The die-casting process can be used to manufacture small precision components such as handles and housings of surgical instruments, as well as brackets and connectors of medical equipment. Its high precision (dimensional tolerance can reach IT9 grade) and good surface quality (Ra value ≤ 1.6μm) can meet the strict standards of medical devices for operational precision and hygiene requirements. For example, the dimensional error of die-cast surgical instrument handles can be controlled within 0.02 - 0.05mm. After passivation treatment on the surface, the corrosion resistance can withstand a neutral salt spray test for 500 hours without rusting.
  1. Other Fields: In addition to the above industries, die-castings are also widely used in motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, garden landscaping, power construction, architectural decoration, and other industries. For example, artistic decorations in garden landscaping (such as aluminum alloy die-cast pattern ornaments with a minimum detail size of 0.2mm), electrical equipment components in power construction (such as zinc alloy die-cast terminal blocks whose electrical conductivity meets the GB/T 13140 standard), and door and window accessories in architectural decoration (such as aluminum alloy die-cast hinges with a load-bearing capacity of more than 50kg) may all adopt die-castings.

Suitable die casting materials

When you are ready to begin your die-casting project, one of the most important decisions you will make is choosing the suitable material. The material you select must be able to withstand the high temperatures and pressures of the die casting process, as well as the demands of your end-use application.

Furthermore, it is important to choose a material that is compatible with the die casting operation you have selected. With so many factors to consider, working with an experienced die-casting partner who can help you navigate the many options and make the best decision for your specific project is essential.

However, aluminium, magnesium, and zinc are three of the most popular die casting materials, as they all are strong and lightweight:

Aluminium alloys

Aluminium is also highly corrosion-resistant, making it an ideal choice for die-cast parts that will be exposed to the elements. Some of its most suitable aluminium alloys for die casting are:

  • Aluminium 46100 / ADC12 / A383 / Al-Si11Cu3
  • Aluminium 46500 / A380 / Al-Si8Cu3

Magnesium alloys

Magnesium alloys such as AZ91D, AM60B, and AS41B are also well suited for die casting due to their high strength-to-weight ratio. In addition, these alloys offer good resistance to corrosion and wear.

Zinc alloys

Zinc, on the other hand, is an excellent conductor of heat and electricity, making it ideal for die-cast parts that will need to be heated or cooled rapidly.
