Last year, the city's equipment manufacturing industry achieved an industry added value of nearly 105.5 billion yuan, an increase of 11.1% year-on-year, and the equipment manufacturing industry accounted for more than 40% of the city's industrial share. This is the first time that the added value of the equipment manufacturing industry in the city exceeded the 100 billion mark. Since last year, enterprises in our city have teamed up with local research institutes to research "machine substitution" technology, and equipment manufacturing companies and application companies have jointly conducted pilot projects for automation (intelligent) equipment training, CSR Ningbo Industrial Base, Beilun High-end Equipment Industrial Park, etc. The construction speed of the new equipment industry development platform has accelerated, and the high-end equipment manufacturing industry has grown by leaps and bounds. Recently, the Provincial Economy and Information Commission issued the "Zhejiang High-end Equipment Manufacturing Development Plan (2014-2020)", which made it clear that the province will focus on "green, intelligent, supernormal, integrated, and service-oriented" in the future. By 2020, the output value of Zhejiang's high-end equipment manufacturing industry will exceed 1.1 trillion yuan, accounting for 25% of the equipment manufacturing industry. This brings new benefits to the city's efforts to develop high-end equipment manufacturing. “This year, the city will further increase the structural adjustment of the industrial economy, strive for equipment manufacturing, strategic emerging industries, and high-tech industries to grow at a faster pace than industry regulations, and contribute to building a strong industrial city.†Say. A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape. It can be also called a [roll bending machine", [plate bending machine" or [rolling machine".

There are different kinds of technology to roll the metal plate:
Four-roller machines have a top roll, the pinching roll, and two side rolls.
The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate.
Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls.
The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders.
For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum mechanical advantage. With the side rolls all the way in, you have the least mechanical advantage. So, a machine has the capability of rolling 2-inch-thick material with the maximum mechanical advantage, but a job is only 1/2 inch thick. Reduce the mechanical advantage and one has a machine that can roll from 1/2 to 2 inches thick.A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape.
