Sealing rings are precision electronic parts, specially designed for harsh working conditions of electronic equipment. Based on high-quality elastic materials, they are formed by precision molds and finely processed to present a regular ring structure with a smooth appearance and precise dimensions. Suitable for various precision electronic instruments, communication equipment and smart terminals, they can effectively fill the gaps between components, build a reliable sealing barrier, prevent the intrusion of water vapor, dust and harmful gases, and buffer vibration shocks, protecting the stable operating environment of electronic components. They are the key basic parts for sealing and protecting electronic equipment.
Special rubber with excellent weather resistance and aging resistance is selected, and it is matched with high-strength reinforcing agent. It maintains good elasticity and sealing performance in a wide temperature range of -40℃ to 120℃, and will not become brittle or fail after long-term use.
Test items | Performance Indicators |
Tensile Strength | ≥15MPa |
Elongation at break | ≥300% |
Compression set (70℃×22h) | ≤20% |
(II) Ultra-high precision
The dimensional tolerance is controlled within ±0.05mm, which is suitable for the tiny gap of precision electronic components. After installation, it fits tightly and seals without dead angles, helping the equipment to achieve high sealing and high reliability design.
(III) Multifunctional protection
It has multiple functions such as waterproof, dustproof and shockproof, creating a "golden bell" for electronic components to resist interference from complex external environments and reduce the risk of short circuits, performance degradation and other failures caused by sealing failure.
III. Product details
From the R&D end, relying on advanced simulation technology, it accurately simulates the stress, deformation and sealing effect of the sealing ring under the working conditions of electronic equipment, optimizes the structural design, and ensures stability and reliability in high-frequency vibration, temperature and humidity alternation and other scenes. In the production process, it adopts fully automatic precision injection molding and vulcanization process, strictly controls the raw material ratio, vulcanization temperature and time, and ensures the consistent performance of each batch of products.
In terms of testing, it is equipped with high-precision image measuring instruments, tensile testing machines and other equipment to fully inspect the size, mechanical properties and sealing performance. For example, in the air tightness test, there is no leakage under 0.1MPa pressure for 30 minutes; the waterproof test meets the IP67 and above standards.
When used, it is suitable for waterproof sealing of mobile phones and smart wearable devices to protect internal circuit boards; it can also be used for industrial control hosts and communication base station equipment to prevent dust and moisture erosion, extend the equipment operation and maintenance cycle, and build a strong sealing defense line for the stable and long-term operation of precision electronic equipment. It is a trustworthy core accessory for the electronics manufacturing industry.
