GRAVITY DIE CASTING
STATIONERY DIE CASTING
Stationery die casting, also known as permanent mould casting, derives its name from the use of long-lasting metal moulds—typically made from steel or cast iron—instead of conventional, single-use sand moulds. These durable moulds provide exceptional reliability and consistency throughout the casting process.
To form the internal features of the casting, we employ cores crafted from silica sand using advanced methods such as the Shell, Amine, or CO₂ process.
The cavity surfaces of the moulds are meticulously coated with fine, heat-resistant materials to ensure thermal stability and smooth metal flow.
Prior to casting, the moulds are preheated to approximately 200°C (392°F) to facilitate optimal metal flow and reduce thermal shock. Molten metal is then carefully poured into the mould cavity under controlled conditions, ensuring uniform solidification. To maintain precise thermal balance during casting, various cooling techniques are employed—including water cooling, air cooling, and selective radiation methods—thereby ensuring the integrity and dimensional accuracy of the final product.
