LCD Cassette is mainly used in TFT LCD process to carry, transmit and protect glass substrate equipment. When PEEK support line is in glass substrate card box, its wear resistanceand high surface hardness,can greatly reduce particle production. Ultra-high purity and low gas release can avoid pollution, so as to improve the process production rate. Because of High temperature resistance, there is no need to cool down between the various stages of process production, thus improving the process efficiency. Chemical resistance can withstand most of the chemicals.The key parts used in process production equipment can prolong the service life of the equipment and reduce the maintenance requirements of the equipment.
