Technical Key Points
Ø Ni, Mo, Cu, ferrochromium, ferromanganese, ferrosilicon and other metal alloy materials used in the smelting must be baked at high temperature before adding, so that to thoroughly remove oil and moisture and prevent the oxidation of molten steel.
Ø Structural characteristics of the valve body castings make it easy to generate shrinkage and slag (sand) defects at the bottom, which seriously affect the pressure resistance of the castings, and may cause leakage of the media matter(water, gas, oil, etc.) during application.when setting feeding riser, feeding gate must be set or extended, if necessary, extend the feeding runner to the bottom of the casting.
2003 Wuxi Lingtong Casting Co.,Ltd. Founded, with main products of sodium silicate silica sand precision casting and sand casting.
2005 Lingtong started to cooperate with LKL located in Netherlands, our products entered EU market.
2008 start to supply castings to WKM in China.
2014 our factory moved to industrial park of Mashan in Wuxi Binhui District, in addition, we added 1.5 tons and 2 tons of medium frequency electric furnace, as well as sand mixer and phenolic resin regeneration system. Formally start bulk production production of cast steel, especially production of stainless steel, carbon steel and duplex stainless steel.
2015.4 our samples provided to Wuxi Hitachi Pump Co., LTD get approval, and start cooperation with them.
2016.10 Established a cooperative relationship with Shanghai Liancheng pump industry Co., LTD.
2017.6 our vertical pump body casting won the award of "Special gold award for quality casting" in 2017 CIFEX. material is CF3M (316L stainless steel), the pump body was exported to the United States.
