Aluminum, a silver-white light metal, has good ductility. The content of aluminum in the earth's crust is second only to oxygen and silicon. It is an important metal material in industrial production. Because of its low melting point and good ductility, it has become the most frequently used metal material in the die casting industry. The fastest route for high-pressure die casting is to complete the molten metal component. It can be removed by injecting the molten metal into a hard steel mold, tool, and letting it cool and solidify under pressure. This process provides an accurate, fast, and low-cost production method.
Aluminum is a suitable metal alloy for rapid die casting. Aluminum is lightweight, has high toughness, plasticity, good dimensional stability, and can realize complex shapes and thin-walled parts. Aluminum does not absorb dust and corrosion resistance, and has good electronic properties and excellent thermal characteristics. Because it is a good conductor of heat, it can retain heat and maintain a good shape.
Heat treatment of high pressure die castings
A heat treatment method that can be used can significantly improve the properties of these aluminum alloys suitable for age hardening. Through heat treatment, the tensile properties, fatigue resistance, fracture resistance and thermal conductivity of aluminum alloys will be improved. High-pressure casting is the most cost-effective process technology for mass production of complex aluminum alloy parts close to the final shape. The heat treatment method provides an idea improvement of tensile mechanical properties for high pressure die castings, and strengthens other material properties.
This new heat treatment process technology is easy to adopt on existing processing equipment such as continuous belt charging furnaces and specialized for rapid fluidization furnace systems. The cost of each high-pressure die-casting part has the potential to be significantly reduced. They all have a rapid strengthening mechanism and have cost and energy advantages in processing.
Improved tensile strength properties. Traditional solution treatment. Aluminum alloy rapid die casting expand pores and cause unacceptable surface pores, resulting in distortion and lower mechanical properties.
|Best steps for alloy heat treatment|
|Alloy type||Optimal solution handling||Quenched||T6 tempering aging||T4 tempering aging|
|All alloys||480-505 degrees Celsius, pay attention to hot or cold water||16-24 hours at 150 degrees Celsius||720 degrees Celsius||It should be more than 10 minutes at 420 degrees Celsius and maximum temperature|
