Why design lifting holes on cast iron platforms

After casting blanks,cast iron platform manufacturers need to stop sand cleaning and disposal of their cast iron platform castings.The sand cleaning method for cast iron platform manufacturers is shot cleaning.The cost of manual sand cleaning is low,and some parts are not disposed of very cleanly.On the other hand,shot blasting and sand cleaning are the opposite,with high costs,and the surface of the cast iron platform is cleaned

After forming,the cast iron platform needs to be ground,and the grinding method usually adopts the three sided mutual grinding method,which is not only the cast iron marking platform transmission method,but also a commonly used inspection method for cast iron platforms.During the flipping and mutual grinding process,deformation of the cast iron platform cannot be prevented.At the same time,consumer manufacturers of cast iron platforms usually design lifting holes on cast iron platforms,which can avoid deformation caused by cast iron platforms.The working surface of cast iron platforms can be processed with V-shaped,T-shaped,U-shaped grooves,round holes,long holes,etc.No matter how the cast iron platform is designed,both sides of the plane should be designed to facilitate easy lifting during transportation.

In order to avoid deformation of the cast iron flat plate series during lifting,it is necessary to use a similar steel wire rope to simultaneously tie the four lifting points on the cast iron platform and smoothly install the cast iron platform onto the transport vehicle.The four support points of the cast iron platform should be well padded to make it sturdy.Stop the inspection of the workpiece on the cast iron platform and handle it gently.Do not damage the working surface of the cast iron platform.The cast iron platform should be placed in a well ventilated and dry place to prevent wet corrosion of the cast iron platform.After use,the workpiece should be removed from the cast iron platform in a timely manner to prevent long-term deformation of the workpiece on the heavy platform of the cast iron platform.
