First of all, the production of silicone sealing ring begins with material preparation. This includes selecting high-quality silicone raw materials and adding appropriate amounts of auxiliary materials such as fillers, stabilizers, catalysts, etc. according to product requirements. The selection and ratio of these materials are crucial to the performance of the final product.
Next is the mixing process. Put the prepared silicone and auxiliary materials into the mixer for stirring so that the various materials are fully mixed and uniform. The mixing time and temperature need to be strictly controlled to ensure the stability of the raw material rubber.
Molding is one of the key steps in the production of silicone sealing ring. The mixed silicone material is processed into the required shape and size through equipment such as extruders or die-casting machines. In this process, parameters such as temperature and pressure need to be controlled to ensure that the size and shape of the sealing ring meet the requirements.
Vulcanization treatment is another important link in the production of silicone sealing ring. The molded silicone sealing ring is placed in a vulcanization tank for high-temperature vulcanization treatment to enhance its physical and chemical properties. Parameters such as vulcanization time, temperature and pressure need to be determined according to the formula of silicone and product requirements.
The vulcanized silicone sealing ring needs to be cooled to ensure the stability of its size and performance. The cooling process needs to control the temperature and time to avoid deformation or cracks of the sealing ring due to uneven cooling.
Next is the post-processing process, including steps such as deburring, cleaning, and coating. These steps help improve the appearance quality and performance of the product. Applying a layer of coating or lubricant can increase the friction and anti-adhesion properties of the sealing ring.
Finally, quality inspection of silicone sealing ring is an important step to ensure product quality. Through appearance inspection, dimensional measurement, hardness test, tensile test and other methods, quality problems can be discovered and solved in time. Only silicone sealing rings that have undergone strict quality inspection can be shipped from the factory.
In short, the production process of silicone sealing ring involves multiple key steps, and each step requires strict control of parameters and quality to ensure that the performance and quality of the final product meet the requirements.
