Bed frame casting

Characteristics of bed frame castings:

(1) The bed frame casting has good shock absorption. Due to the favorable lubrication and oil storage properties of graphite in cast iron, its performance is good. Similarly, due to the superior shock absorption properties of graphite compared to steel.

(2) Good process performance. Due to its high carbon content and eutectic composition, gray cast iron has a relatively low melting point, good flowability, and low shrinkage rate, making it suitable for casting complex or thin-walled castings. In addition, due to the tendency of graphite to form chips during cutting, the machinability of gray cast iron is superior to that of steel. Our factory also produces various large casting products such as machine tool bed frames, large castings, and vertical lathe castings.

Bed frame castings are the basic castings used in the mechanical operations of various industries such as machinery, machine tools, shipbuilding, automobiles, and electricity. They are also known as machine tool castings or machine bed frame castings, and are commonly used as bed frames for various large machine tools. They can also be processed and directly used as machine components. To meet the usage needs of different users,

Sand casting is preferred for machine tool bed castings, mainly due to its lower cost, simpler production process, and shorter production cycle compared to other casting methods. When the wet mold cannot meet the requirements, consider using clay sand surface dry sand mold, dry sand mold or other sand molds. Machine bed castings are manufactured according to standards. Resin sand molds have good rigidity, and in the early stage of casting, it is possible to utilize the graphitization expansion, shrinkage, and porosity defects during the solidification process of cast iron to achieve low riser and no riser casting of gray cast iron and ductile iron parts.
