The frame is often made from casting or sealing-in, the material of frame often use casting steel, for example ZG35. With the development of sealing-in technology. Most frame of jaw crusher is made by steel welding. After welding, destressing, shot peening treatment processes, the quality of jaw crusher plate can be guaranteed in good state.zoneding Machine can produce two kinds of jaw crusher frame, Customers can choose the best one according to their demands.
Moving jaw usually use the whole cast steel structure by mechanical processing manufacture ,but at present there are some products adopt welding production.
Jaw plate is a wearing parts, it is often made of high manganese steel.There are moving jaw and fixed jaw, the size of the jaw plate is dfferent according to the type of jaw crusher.
