1. Raw material quality problem: If the quality of rubber raw materials used in the production process is uneven, the hardness of the final product may be inconsistent.
2. Formula problem: Improper formula during rubber mixing, such as incorrect proportions or uneven dispersion of each component, will lead to differences in hardness in different parts of the hose.
3. Mixing process problem: Improper control of parameters such as temperature, time, and pressure during rubber mixing leads to uneven mixing, making the rubber properties of different parts different.
4. Vulcanization process problem: Uneven temperature control: Uneven temperature control during vulcanization will lead to differences in hose hardness. Inconsistent vulcanization time: Too long or too short vulcanization time will affect the hardness of the rubber. Uneven vulcanization pressure: Uneven pressure during vulcanization will also lead to uneven hardness.
5. Production equipment problem: Aging or failure of production equipment may cause the temperature, pressure and other parameters in the production process to be unable to be accurately controlled, thereby affecting the hardness of the product.
6. Uneven wire weaving: Inconsistent tension during wire weaving leads to uneven distribution of wires, which will affect the overall hardness of the hose.
