Die Casting Toolings in China

Toolings are fundamental to die casting production. The quality affect straightly the production efficiency, casting parts quality and production cost, also the survival and development of casting companies.

Nowadays, with the booming of domestic automotive industry, especially domestic auto companies, Chinese casting industry has been developed fast and well. Die casting is applied to manufacture aluminum alloy blocks or magnesium alloy blocks, which meets the requirement of light weight. These kinds of toolings are very difficult to make. In the past, most of these toolings used in China were imported from Europe or Japan. And now, the technologies of casting toolings has been improved and mature. More an more toolings manufactures are able to make block casting toolings with three cavities or four cavities by themselves. And in the tend of saving energy and reducing pollution, the die casting toolings market is very large.

Since 1990s, the toolings has developed into larger, more complex, longer in lifetime. And in the past two years, the appearance quality and lifetime of toolings has been enhanced. In the process, CAD/CAM is applied widely in toolings design; some companies utilize software of finite element analysis to analyze flow field and temperature field , such as ANYCASTING, PROCAST, etc; processing program of fine finishing after quenching is adjusted widely, and other advanced equipments and technologies are recruited and developed.

Nowadays, the casting toolings these are used in household appliances, motorcycle industry, etc totally could meet the dometic requirements. And the domestic share is raised gradually. Meanwhile, most of large, high precision, complex casting toolings need to be imported. However, some toolings made by Chinese manufacturers has been exported to developed countries.
