Thermo shrink end caps are typically used to seal cable ends and provide mechanical and environmental protection, inner wall with glue coating, provide excellent seal to moisture.
How is the thermo shrink end cap is coated with adhesive?
There are two kinds of common glue coating methods: hand scraping and spiral spraying by machine, both of which are as follows:
Hand scraping, is using artificial way to use chopsticks tools such as dipped in hot melt, and then shrink rapidly to the inner wall of the cap scraping, the technology is low quality, scraping by artificial factors greatly, the product wall scraping is not uniform, so the quality control is not stable, the sealing is poor, in there are high requirements of the occasion is not suitable, The glue coated by hand is not continuous, and the depth is serious, which is very harmful to the quality of the product.
Spiral spraying, the advanced technology, automatic coating equipment in the nozzle cap sealing wall uniform injection strip of hot melt adhesive liquid under the control of the program, After retraction of cable end cap, the inner wall of end cap covered with a spiral hot melt sealing,
