We maybe meet some problem of the fire sleeve appearance. How to identify them? I will make a presentation for you.
Pimple Figure 1: The fiber bulge caused by the yarn replacement or finishing process of the product, the pimple generated after being coated with silicone and vulcanized at high temperature and will not affect the strength, elasticity, heat insulation and other effects of the product itself
Crack Figure 2: The coating is not fully covered due to partial surface unevenness, which has no effect on actual use.
Flow mark Figure 3: Flow marks appear during natural coating ,due to the hardening of the initial dispensing tumor.
Crease Figure 4: The product will not produce creases during the production process. Due to the thick silicone coating layer, after the casing is folded and squeezed for a long time after storage, there is a possibility that individual creases will occur. have no effect on the performance of the product.
What we will do to solve this problem?
Quality Control:
Conduct quality awareness training for employees, strengthen production process quality monitoring, and conduct 100% inspections.
