Small parts in every industry will be used, so there are a lot of penny-wise and poundlessly happened around us, in various industries sealing protective supplies without the assistance of silicone parts materials, many products in the combination of silicone parts and influence can play a great role in the effect, and the deployment of softness and hardness can completely affect any functional problems, So the hardness of silicone parts if the choice is not appropriate will also produce quality problems, different hardness and softness on the function of what impact!
Spare parts are mainly used for assembly, sealing, shock absorption, protection and intermittent and other aspects, and the soft and hard value of silica gel in different functions have drawbacks.
In the sealing function, if the hardness of the silicone sealing parts is high, the folding and fitting strength is low, it is likely to lead to the leakage phenomenon of slack singing, and the life after long-term aging will be affected to a certain extent, the phenomenon of damage and cracking, the low hardness function can be buffered, and the hardness can be reduced as much as possible in the waterproof function to achieve a more effective waterproof effect. However, the material and thickness of the product must be appropriate to achieve good extended resilience.
In terms of cushioning and damping, silicone products need to achieve as high a hardness value as possible, due to the influence of the force, the low hardness of the product is likely to lead to its insufficient shock absorption effect, unable to achieve functionality, followed by low hardness silicone parts assembled due to the influence of strength is likely to achieve the impact of active buffer shock resulting in loosening and falling off. After the hardness value is increased, it can not only improve the firmness, but also achieve the buffering effect because of the high hardness value.
Assembly, many silicone parts manufacturers understand that sealing parts are assembled with different materials, and the completeness of the assembly is also affected by the hardness of the incomplete product functional problems, high hardness materials is not easy to assemble, and the higher the hardness of the tensile resilience is smaller, so high hardness accessories assembly as much as possible to reduce its tensile degree, low hardness assembly is better, But also pay attention to the problem of stretching too much.
