Bad Features Of Sealing Ring Products
Jun 06, 2022
1. Impurity: If it is not compatible with the rubber material, it will show different colors or obvious foreign matter on the product.
2. Cracks: There are obvious cracks on the inner and outer surfaces or other surfaces of the sealing ring product.
3. Degumming: The rubber material of the sealing ring product is separated from the skeleton and cannot be bonded together.
4. Lack of material: There is no obvious outline of the sealing ring product, or there is no glue injection in some parts, or the glue injection is not satisfied, or there are obvious signs of glue flow.
5. Air bubbles: The surface of the sealing ring product has obvious protrusions and is spherical.
6. Flow marks: There are obvious lines on the surface of the sealing ring product, and the surface is shiny and linear.
7. Dirty mold: The surface of the sealing ring product has an obvious lack of smoothness.
8. Mold marks: During the production process or use of the mold, the cavity is bumped or scratched, causing the corresponding surface of the product to be dented or raised (the same cavity product is the same).
9. Burning: There is obvious scorch on the surface of the sealing ring product.
10. Repair: Button teeth appear in the trimming part, which will destroy the colloid of the product itself.
11. Unilateral: Symmetrical parts appear inclined, with more on one side, less on one side, or one side and one side without. For example, the upper end face of the incision has a large width on one side and a small width on the other side, and the wall thickness is uneven.
12. Car damage: There are obvious cutting marks on the cutting surface or the cutting edges are not neat and serrated.
13. Glue overflow: encapsulate the exposed part of the product with the exposed skeleton.
14. Miscellaneous colors: There are impurities that are different from the color of the product rubber due to rubber materials, molds, etc.
15. Coil: There is a wire ring on the surface of the sealing ring product.
16. Freezing: The product is frozen and trimmed to cause product gaps or cracks. A good and qualified sealing ring is a prerequisite to ensure the normal operation of mechanical equipment.
