Aluminum die-cast parts have been widely used in various industries around the world, thanks to the extreme corrosion resistance, high electrical and thermal conductivity, high stability and high tensile strength of complex shapes, and unique light weight of aluminum alloy die castings. The automotive industry prioritizes the use of lightweight, high-quality aluminum alloy die castings to replace some of the steel parts in vehicles to improve fuel efficiency. Also aluminum alloy die castings are ideal for electronic connectors and housing molds because of their excellent heat dissipation properties, excellent electrical performance and shielding properties even in high temperature environments.

Fifty percent of what ends a consumer’s purchase is driven by one person’s emotions. This is especially true when shoppers are torn between two brands that offer the same product. In his book “The Brand Gap” Marty Neumeier writes, “The retail package is the last and best sales opportunity. If your product’s packaging succeeds in reaching consumers on an emotional level, it may increase the likelihood that you will be able to take advantage of your last and best sales opportunity.
Inc. notes that about 95 percent of new products fail every year. With about one-third of product decisions based on packaging alone, you can improve your product’s chances of commercial success by being compelling. Drupa says a product typically has about seven seconds to impress consumers in a positive way. With the right packaging materials and design, your product will attract shoppers and enable consumers to make a quicker and easier purchase choice.
According to the research of related institutions, the aluminum alloy die casting produced in Asia-Pacific region accounts for more than half of the global aluminum alloy die casting market share. And in the next 5-10 years, the growth rate will reach 200%, while China, as the world’s aluminum alloy die casting powerhouse, will contribute about $6 billion in output value. Another important region belongs to Europe and North America, Europe is expected to grow at a CAGR of 5.1% to reach $945 million during the forecast period, and North America is expected to grow at a CAGR of 4.9% to reach $2,220.25 million.

Currently, the main alternatives for aluminum alloy die castings with low requirements for accuracy and appearance are sand casting and investment casting.
Sand and investment casting are methods of manufacturing metal parts by pouring molten metal into prefabricated molds. The industry has been around for thousands of years, and there are significant differences between these two methods of manufacturing metal parts. Over the years, the sand and investment die casting processes have been refined to reduce the amount of metal used.
Sand casting is known as the oldest and most widely used casting method because of its unique versatility. The molten metal is poured directly into the sand mold and then cooled to shape, without the need to apply external pressure. Many identical parts can be cast at the same time and share a single mold, and the same sand mold can be reused many times, so this method is preferred for small batches of aluminum parts. However, this method usually results in a final product with less detail or a rough surface, which usually requires subsequent grinding and polishing before it can be put into service. The advantage of sand casting over investment die casting is that the mold design can be easily changed when the product shape needs to be changed.
Compared with aluminum alloy die-casting, sand casting is simpler and faster. If you need to produce small quantities of aluminum alloy parts with low requirements for precision and surface treatment, you can prefer sand casting, which can save a large amount of mold development and manufacturing costs and reduce the cost of products to improve the market competitiveness of products!
