The 21Century Co., Ltd. produces a variety of ultra-precise vacuum plates used in MLCC and semiconductor industries.
Because industrial vacuum plates have large suction holes, they can damage objects, and the demand for precision vacuum plates composed of micro holes is increasing. In the case of thin sheet-type products such as Film, a vacuum plate made of micro holes is needed because if the hole is large, the product may be damaged or embossed.
As a result, in the 21Century, high-precision vacuum plates consisting of micro holes from Ø0.1 to Ø0.03 are produced and supplied to various industrial area. Although the vacuum plate made of Porus Ceramic is widely used in the semiconductor field, it is unstable in high floor plan and uniform pressure management due to the size of the particles, and the importance of the vacuum plate of 21Century is emerging.
Although it varies depending on the size of the specification, we manufacture and provide the highest quality and performance vacuum plates for customers’ needs with 0.001 floor plan management and precise suction hole management up to Ø0.03.
The 21Century Vacuum Plate, which boasts high quality and performance, was selected as the next world-class product in 2023 and won the official brand certification of the Korean government as a leading product and company in the global market.
