Most of the sealing rings are made of silica gel or rubber materials. They are commonly used in sealing. As a sealing product, they have the characteristics of stability, easy processing, high elasticity and resilience, and will not corrode the contact surface so that they have good sealing performance. , are widely used in various industries such as automobile, aviation, medical, machinery, energy, food, drinking water, sanitary ware, etc.
The detection content of the sealing ring can be detected from the aspects of appearance, air tightness, hardness, tear resistance, high temperature and so on. The burr of the sealing ring is also called trimming, which is a common process in the production of rubber products. Each manufacturer can choose a suitable trimming method according to the quality requirements of the product and its own production conditions. Currently Linde Polymer adopts the following trimming methods according to the size of the product.
1. Manual trimming: Manual trimming is an ancient method of trimming.
2. Mechanical punching and trimming: With the help of pressure machinery, punching dies, and punching knives, the rubber edges of silicone products are removed.
3. Frozen trimming machine equipment: the principle is to use liquid nitrogen (LN2) to make the burr of the finished product brittle at low temperature, and use specific frozen particles (projectiles) to hit the burr to quickly remove the burr.
4. Use the mold without flash for production: the trimming work becomes simple and easy (the flash will be removed as soon as it is torn, so this kind of mold is also called the edge tearing mold).
Linde Polymer mainly produces various rubber compounds and rubber seals. At present, there are more than 3,000 material formulas and more than 2,000 specifications of products. The products are suitable for automobile, aviation, machinery, petrochemical, sanitary, medical, food, electronics, national defense, military, industrial and other fields. Since the establishment of the factory, the company has completed the consistent operation of the manufacturing process, and the yield rate of the product manufacturing process has reached 97.1%. In terms of quality assurance, it has passed the ISO/TS16949 quality certification, and the products also have UL and NSF certification. And meet the standards of major industrial countries such as Japan, the United States, Germany, and the specifications of the US military and the specifications of OEMs such as TOYOTA, HONDA, NISSAN, GM, FORD, CHRYSLER, GE, etc.; in the next few years, we will focus on TQM, and ISO14001, etc. Management system recognized as.
