Aluminum Casting Process Requirements

Aluminum die casting is a kind of pressure casting part. It uses a pressure casting mechanical die casting 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 casting by the die casting machine. Aluminum parts or aluminum alloy parts that are restricted by the shape and size of the mold, such parts are usually called aluminum alloy die castings. Aluminum die-casting parts are called differently in different places, such as aluminum die-casting parts, die-casting aluminum parts, die-casting aluminum parts, die-casting aluminum, aluminum die-casting parts, 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 parts can be made of various more complex shapes and can also be made with higher precision And smoothness, thereby greatly reducing the machining amount of castings and the casting margin of metal aluminum or aluminum alloy, not only saving electricity, metal materials, but also greatly saving labor costs; aluminum and aluminum alloys have excellent thermal conductivity Performance, small specific gravity and high processability.

As a result, aluminum alloy die castings are 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 other industries. Aluminum die-casting parts can be manufactured as aluminum die-casting auto parts, aluminum die-casting automobile engine pipes, aluminum die-casting engine cylinders, aluminum die-casting gasoline engine cylinder heads, aluminum die-casting valve rocker arms, aluminum die-casting valve seats, aluminum die-casting power accessories, aluminum die-casting Motor end cover, aluminum die-cast housing, aluminum die-cast pump housing, aluminum die-cast construction accessories, aluminum die-cast decorative accessories, aluminum die-cast guardrail accessories, aluminum die-cast aluminum wheels and other parts.

  1. For the produced die-casting parts, the dimensions and various technical requirements specified in the product drawings should be guaranteed, and the machining parts and machining allowances should be reduced;
  2. The mold should meet the technological requirements of die-casting production;
  3. On the premise of ensuring the quality of castings and safe production, a reasonable, advanced and simple structure should be adopted to reduce operating procedures, so that the action is accurate and reliable, the rigidity of the components is good, and the vulnerable parts are easy to replace and repair;
  4. The various parts on the mold should meet the requirements of mechanical processing technology and heat treatment technology, the material selection is appropriate, the matching precision selection is reasonable, and the technical requirements are met;
  5. Master the technical specifications of the die-casting machine, give full play to the production capacity of the die-casting machine, and accurately select the installation size;
  6. When conditions permit, the mold of Power tools die casting part should be standardized and generalized as much as possible to shorten the design and manufacturing cycle and facilitate management.
