Drop forging is when half of the die is dropped from a height onto the other half of the die, which will contain the hot metal workpiece to be formed. Drop forging is used for mass production.
Press forming is instead of dropping half the die onto the other half the two halves are put together and pushed together under a large pressure (up to about 10000 tons) forming the object
the difference is that drop forming leaves the centre of the metal not so hard as the outside, but press forming gives more uniform hardness for larger components

What are the differences between open die forging and close die forging?
-Open Die Forging is taking hot steel and shaping it with "flat" dies (sometimes angled; sometimes used for making "steel wheels".) Open die forging is mainly used to elongate steel. -Closed Die Forging is taking hot steel and shaping it with impression specific dies such as tie rods, crank shafts, and yokes. -In some cases parts need to be open forged, then closed forged. We are a Chinese drop forging company for various closed die forging parts,check our website dropforging.net and contact us while there is any inquiry!

What is the difference between CSS box shadow and CSS filter drop-shadow?
A CSS box shadow effect is applied to the outer layer of an element while the filter drop-shadow, an experimental property, follows the rendered shape of any element including pseudo elements, such as a tootip with an arrow. A filter drop-shadow also takes into account the transparent aspects of a .png image.
