La plus grande fabrication de sable de fonderie de céramique en Chine

Brève description:

Ceramic foundry sand, technically named as “Sintered Ceramic Sand for Foundry”, some factories also named as ceramsite, cerabeads, ceramcast, is good artificial ball sand for foundries. Its main content is aluminum oxide and Silicon oxide. Ceramic foundry sand compare with Silica sand, it has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, high resistance to wear, crush and thermal shock, high reclamation rate, it could reduce the resin addition and coating amount, increasing your castings yield, more than ten times the number of reclamations. Compare with black ceramic sand, it has almost same properties except lower bulk density and higher more than 3 times reclamation. Sintered ceramic sand bulk density is 1.45-1.6 g/cm3, but black ceramic sand is 1.8-2.1 g/cm3.

Avantage

 

● Ceramic foundry sand offers longer work life and reduction of sand usage

● Ceramic foundry sand spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility resulting in lower scrap and casting efficiency

● Ceramic foundry sand offers lots of price savings compared with Zircon, Chromite, Black ceramic sand, Naigai cerabeads sand

● Safe to environment compared with Silica (silicosis) sand

● Lower thermal expansion and thermal conductivity. Casting dimensions are more accurate and lower conductivity provides better mold performance

● Nécessite 30 à 50 % de résine en moins

● Peut être utilisé comme un seul sable

● Offre une densité réelle et une surface spécifique inférieures

● Durabilité améliorée par rapport aux autres sables de fonderie

Application

 

As a neutral material, Ceramic foundry sand is both used to acid and alkali resins.

It can be widely used in all kinds of sand molding, such as resin-coated sand, self-setting resin sand, cold core box, green sand, precision casting, lost foam casting and 3D printing etc., excellent properties help you reduce more production cost.
