Moulds were made with furfuryl moulding sand with the following initial composition: matrix: 90 mass% reclaim of high-silica sand + 10 mass% fresh high-silica sand, together 100 parts by mass; Kaltharz 8117 furan resin, 0.90 parts by mass; and 100T3 activator, 0.35 parts by mass (bulletins and manufacturers).
The alkyd resin – a complex oil-modified polyester – is used for the no-bake moulding process, especially where stripping times are long (i.e. min 1 hour). Its percentage of use is about 0,8-0,6% on the sand weight, lower than traditional binding systems such as the phenolic and furan ones. It is totally anhydrous, thus avoiding long and ...

Application. Most resins are suitable for use on both new and reclaimed sand ildeally at additions of 0.65 - 1.2%. Due to the range of nitrogen contants available, the resin can be chosen, which gives the most metallurgically and economically acceptable system.
Furan Resins for foundry industry. The biggest furan resin manufacturer in the world with 200,000MT annually plant. The biggest furfuryl alcohol manufacturer in the world. Continuously development on lower VOC emissions, lower odor resin series. Lower monomeric furfuryl alcohol content resin without any sace on strength.
+1(306)612-1114 4.1 Furan No-bake Process For furan bonded ceramic sand, its hardening rate is much higher than silica sand, and when adding the same amount of resin, the strength is remarkably improved. To test the tensile strength of ceramic sand and Dalin silica sand, add 1.2% furan resin of the

Omega Sinto Provides Mixing Technology for all Foundries. The first continuous mixers were developed by Omega (then Baker Perkins) in the early 1960's for use with molasses and silicates, but in the early 1970's furan resin bonded sand had started to become popular for mould production due to its flexibility and speed of curing.
What is Resin sand molding plant . The resin sand casting process, conceptually similar to sand casting process, has . peculiarities as the type of elements used in the making of the mold.-It takes, phenolic resins and urea-furan which, together with a chemical catalyst, are mixed before forming to the sand.
Fundamentals of Sand Reclamation How easily the acid catalyzed furans and phenolics on reclaim depends primarily on how much resin is used to bond the sand and how much resin is burned away by casting operation. Experimental data and experience in dicate that both the furans and phenolics are quite thermally stable.
For a reclamation plant to realise the full value of a sand reclamation system, it must operate at optimal efficiency. Without the careful monitoring of outputs and control parameters in place, the foundry could risk an unacceptably high level of casting defects as well as lost production – and thus revenue.
