1.3mm Single Wire Seal

In terms of materials, Guoming Rubber uses compounded rubber and special adhesives from publicly listed companies, which are characterized by excellent quality, reliable performance, and diverse specifications. The special adhesive is made from virgin rubber and possesses special properties such as high tear resistance, low compression set, self-lubrication, and flame retardancy, meeting the specific requirements of automotive parts. The 1.3mm single-wire seals produced by Guoming Rubber have excellent waterproof and dustproof properties, and the designed sealing rings provide effective protection against water penetration, ensuring the inside of the connector remains dry. Furthermore, the use of high-strength materials ensures durability and prevents loosening or detachment even after prolonged use.

Quality control advantages:

Guoming Rubber utilizes both CCD and manual inspection methods. For orders involving tens of thousands or even hundreds of thousands of single-line sealing components, CCD inspection is used for screening, which not only controls quality but also allows for rapid sorting, enabling delivery to customers in a very short time. For other types of sealing rings, where machine inspection is not feasible, manual full inspection is employed. The company has 200-300 full-time inspectors who are highly skilled and knowledgeable about the characteristics of automotive connector seals, allowing them to quickly identify and separate defective products from high-quality ones.
