Sand core manufacturing

As a concept of advanced casting industry integrated online service provider,Liujing Technology Group to give full play to its advantages in casting technology, environmental protection technology, supporting services, and continue to extend the casting service industry chain, has become a number of foundry enterprises sand core supplier.

Liujing Technology Group, the sand core made of ‘cast heart’ brand coated sand has high strength, good air permeability, yielding and routing. At the same time in the realisation of process support, reduce the pressure of the front-end pollution of foundry enterprises, can effectively reduce the cost of transport and storage of foundry enterprises, reduce the pressure of foundry park logistics and dust pollution.

Technical features and advantages

● High strength: the sand core can withstand the pouring of metal liquid and maintain a stable shape and structure.

● Good air permeability: during the pouring process, the sand core is able to quickly expel the gas generated, avoiding defects such as porosity inside the casting.

● Excellent yielding and routability: after the casting is cooled and solidified, the sand core can be easily separated from the casting for subsequent cleaning.
