Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tape production equipment, specifically a tape extrusion die. Background Technology
[0002] HTV tape is a type of tape made primarily of high-temperature varnish. It features the following characteristics: High-temperature resistance: Maintains stable performance at high temperatures, resisting aging, deformation, or loss of tack. Good adhesion: Possesses excellent bonding properties, firmly adhering to various materials. Chemical stability: Exhibits good stability against most chemicals and is not easily corroded. Ease of processing: Can be easily processed into various shapes and sizes.
[0003] HTV tape comes in different thicknesses and is produced by extrusion dies of different specifications. The thinner the HTV tape, the more difficult it is to process the extrusion die, which can easily result in the surface roughness not meeting the requirements, thus causing the tape quality to fail to meet the requirements. The existing 0.5mm die is integrally formed, which is difficult to process and the surface roughness is also difficult to meet the requirements. Therefore, a tape extrusion die is needed to address the above problems. Utility Model Content
