Ningbo Fly Engineering Machinery Co.,LTD products

The main alloy elements of lost wax casting bucket teeth&adapter are C,Si,Mn,Cr,Al,ect.To improve the performance,we could also add some microelements,like Mo,Ni so that the wear resistance will be better. The hardness of investment casting bucket teeth & adapter is about 48HRC with impact over 15J under the condition of room temperature.

In our foundry, usually used material for casting the valve bodies are Carbon steel, alloy steel, cast steel. Materials standard include ASTM A148 Grade 80-50, A148 Grade 90-60, A148 Grade 105-85, A148 Grade 115-95. ASTM A216 WCC, WCB, LCC. GB/T 16253, ZG240-450B, ZG280-520, ZG20SiMn. Heat treated in ways of Hardening, Quenching, Normalizing, Tempering, Annealing, Case hardening, Induction hardening, etc.

Alloy steel. Current material used for casting this ripper point is alloy steel ASTM A4340. The main alloy elements Mn,Cr,Mo,Ni. Such alloy steel castings made in China foundry with certain heat treating process can achieve a good mechanical properties and hardness of the products. Thus, to ensure the wear resistance and lift time for using such lost wax casted ripper point. Such lost wax castings, can be used to be assembled onto the agricultural machines used in soft and rock condition soils.

Cast steels,Alloy steels & Carbon steels. Current material used for casting the pump body casted in our foundry is ASTM A148 standard. We can lost wax cast according to custom chemical components, and achieve required mechanical properties by heat treat processes, such as hardening, tempering, normalizing, annealing, case hardening, induction hardening process, etc.

Pump impeller is the hydraulic core part of pump and the quality will directly decide the system properties of pumps.Mostly the pump impeller has thin wall with twisted blade,and its structure is also complex,so it always require high accuracy dimensions and good surface roughness.Currently,we normally use lost wax casting process to manufacture pump impeller.Then why do we use lost wax casting process?Firstly,lost wax casting is suitable for most metal casting parts.Secondly,it could cast out impeller with good surface finish.Secondly,no quality is limited and high volume is available.Finally,lost wax casting process has replaced fabrication process,so it is with good financial savings.

Lost wax cast hydraulic roller made in Fly foundry China are used to build the hydraulic machinery all over the world. Material used to cast the lost wax cast hydraulic roller are alloy steel(42CrMo4, 20CrNiMo), carbon steel(GB45, ASTM 1045), stainless steel(SS304, SS316) and brass.

Fly lost foam casting foundry casts and machines various valve castings for customers around the world. In our foundry, usually used material for casting the valve castings are Carbon steel, alloy steel, cast steel. Materials standard include ASTM A148 Grade 80-50, A148 Grade 90-60, A148 Grade 105-85, A148 Grade 115-95. ASTM A216 WCC, WCB, LCC. GB/T 16253, ZG240-450B, ZG280-520, ZG20SiMn.
