PURPOSE:To safely and easily coat a core material with fluororesin at a relatively low temperature and coat a core material having deteriorated heat resistance or even a long core material having a large port diameter with the resin. CONSTITUTION:The method for manufacturing a fluororesin coating comprises the steps of pressurizing a fluororesin tube having a smaller inner diameter than an outer diameter of a core material in the case of manufacturing the coating by coating a surface of the material with the tube, orientating the tube until it becomes larger than the outer diameter of the material, inserting the material into the orientated tube, and then thermally shrinking the tube to bring the material into contact with the tube. |
