Rubber seal production process: Uncovering the secrets of the manufacturing process to ensure quality and performance

As an important part of industrial equipment, the quality and performance of rubber seals directly affect the safe operation and production efficiency of the equipment. The manufacture of high-quality rubber seals requires strict production processes and procedures. This article will reveal the production process of rubber seals and how to ensure their quality and performance.

1. Raw material selection

The quality and performance of rubber seals are closely related to the selected raw materials. Usually, nitrile rubber, propylene rubber, silicone rubber and other rubbers with good wear resistance, aging resistance and oil resistance are used as raw materials. When selecting raw materials, it is necessary to consider the working environment, temperature, pressure and other factors of the seal to ensure that the seal has suitable physical and chemical properties.

2. Mold manufacturing

Rubber seals have various shapes and sizes, and suitable molds need to be designed and manufactured. The precision and quality of mold manufacturing directly affect the molding quality of the seal. Advanced technologies such as CNC machining are usually used to ensure the precision and stability of the mold to meet the molding requirements of the seal.

3. Molding process

Molding is a key step in the production of rubber seals. Compression molding, injection molding and other processes are usually used. During the molding process, it is necessary to control parameters such as temperature, pressure and time to ensure that the rubber material flows fully and fills the cavity in the mold, so that the seal is fully molded and has good sealing performance.

4. Post-processing process

After molding, post-processing processes such as trimming, annealing, and cleaning are required. These processes can further improve the surface quality, elastic recovery and aging resistance of the seal, ensuring its long-term stable operation.

5. Quality control

Quality control is crucial throughout the production process. Through strict raw material procurement, production process control, finished product testing and other means, ensure that the quality and performance of rubber seals meet the design requirements and customer needs.

6. Experimental verification

Finally, experimental verification is required to perform performance testing and quality inspection on the produced seals. Through sampling inspection, pressure testing, sealing performance testing and other means, ensure that the quality and performance of the seals meet the standard requirements.

In summary, the production process of rubber seals involves multiple links such as raw material selection, mold manufacturing, molding process, post-processing process, quality control and experimental verification. Only through strict process control and quality management can the quality and performance of rubber seals be guaranteed and reliable sealing solutions be provided for industrial production.
