A chill in casting purpose is to control the solidification sequence of the casting, accelerate local cooling to improve the casting quality.
The purpose of a chill in casting has the following six main functions:
Accelerated Solidification
Condenser is a material with high heat capacity and thermal conductivity. It is often placed at the edge or inside the mold cavity to accelerate the cooling rate in that area. This helps to change the solidification sequence of the casting so that the casting solidifies in the desired order.
A chill in casting of prevent shrinkage and pores
A chill in casting is to place condensates in locations where it is difficult to feed material through risers can prevent shrinkage and pores from forming. This is because the condensates can quickly absorb heat, thereby reducing the occurrence of these defects.
Improve mechanical properties of a chill in casting
A chill in casting is by accelerating cooling in local areas, condensates can refine the grain structure of the casting, thereby improving the mechanical properties of the casting, such as strength and toughness.
Controlling thermal stress
Condensate can reduce thermal stress caused by temperature gradients by accelerating cooling in local areas, thereby preventing cracks.
A chill in casting improving production efficiency
Using condensate can increase the feed distance of the riser and reduce the number of risers required, thereby improving production efficiency.
Surface hardening
A chill in casting, in some cases, condensate can also be used for surface hardening to make the surface of the casting hard and durable, suitable for applications requiring wear resistance.
Haichen die casting machine
Haichen, is one Chinese machine manufacturer produces high pressure die casting machines. It includes cold chamber die casting machines and hot chamber die casting machines.They have high durable and precise features. we have auxiliary machine-cooling chillers for option.
The purpose of a chill in casting in the casting is to control the solidification sequence and quality of the casting by locally accelerating cooling. Thereby improving the overall performance of the casting and production efficiency.
