is a kind of pressure-casting parts. It uses a pressure-casting mechanical machine equipped with a casting mold to pour the heated liquid aluminum or aluminum alloy into the inlet of the die-casting machine, and then die-cast by the die-casting machine to cast the mold Aluminum parts or aluminum alloy parts with restricted shapes and sizes. Such parts are usually called aluminum alloy die-casting.
Aluminum alloy die-casting has different names in different places, such as aluminum alloy die-casting parts, die-cast aluminum parts, die-cast aluminum parts, die-cast aluminum, aluminum alloy die-casting, aluminum alloy die-casting parts, etc.
Because metal aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is cast in a pressure die-casting machine, aluminum alloy die-casting can make a variety of more complex shapes, and can also make higher precision and Smoothness, which greatly reduces the machining amount of castings and the casting allowance of aluminum or aluminum alloy, not only saves electricity, metal materials, but also greatly saves labor costs; aluminum and aluminum alloys have excellent thermal conductivity , Small specific gravity and high workability; thus aluminum alloy die casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, electric motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, architectural decoration And so on in various industries.
Aluminum alloy die-casting can be manufactured into aluminum alloy die-casting auto parts, aluminum alloy die-casting automobile engine pipe fittings, aluminum alloy die-casting engine cylinders, aluminum alloy die-casting gasoline engine cylinder heads, aluminum alloy die-casting valve rocker arms, aluminum alloy die-casting valve seats, aluminum alloys Die-casting power accessories, aluminum alloy die-casting motor end covers, aluminum alloy die-casting shells, aluminum alloy die-casting pump shells, aluminum alloy die-casting construction accessories, aluminum alloy die-casting decorative accessories, aluminum alloy die-casting guardrail accessories, aluminum alloy die-casting aluminum wheels, etc. .
The four basic processes in the die-casting aluminum industry are annealing, normalizing, quenching and tempering. These four processes are called the “four fires” in die-casting. In the process of die-casting, the relationship between quenching and tempering is very close. , Both are indispensable.
