ManySilicone TubeAfter manufacturing, some parts need to be spray painted according to customer requirements, but the silicone tube surface will have many small particles after painting. Is this due to the inherent nature of the product or a defect caused by the spray painting process?
Firstly, the main factors causing granules on the surface of the oil-spraying silicone tube are as follows:
Silicone tubes were not cleaned properly before spraying, such as having fine hair or dust on the surface. If they are sprayed without inspection, particles are likely to occur.
2、Silicone TubeInsufficient vulcanization time in the mold extrusion molding machine results in the silicone tube not being fully cured; there may be raw material on the surface and also particle formation.
3. Overheated vulcanization temperature led to air marks on the silicone tube surface.
4. Extrusion silicone tube machines have leftover material or damaged molds.
Additionally, the purpose of spraying silicone tubes is to make the product feel smoother and more comfortable to the touch. However, not all silicone tubes require spraying, as those like food-grade silicone tubes and high-grade silicone tubes that come into direct contact with the human body have been tested and certified accordingly. Silicone touch oil, being a surface ink coating, is non-toxic but should not come into direct contact with the human body. Therefore, when selecting silicone tubes, one should consider the product's intended use before deciding whether to apply the touch oil.
