They are used Sealing and protective effect.
So how to make an oil seal? Let’s take the TC oil seal as an example. The first step requires raw materials, that is, rubber and skeleton. In the past, rubber required a cutting machine to cut it to the appropriate size. Now, rubber is pre-formed, which is more convenient and can be used directly. The skeleton is The iron shell is made of stamped iron, but in order to ensure that the skeleton is more effective and does not rust, we need to rinse the skeleton in formaldehyde and bake it in an oven to ensure the durability of the oil seal. They complete the first step together with the mold preparation work. Usually the rubber we use is NBR/nitrile rubber and FKM/VITON fluorine rubber.
The second step is the vulcanization process. Install the mold of the required size on the vulcanizer. Place the corresponding frame and rubber on the mold. The vulcanizer vulcanizes the rubber at a high temperature of about 180°C. The product is completed in about 90 seconds and waits for cooling. But the products produced are surrounded by rubber and are not finished products.
The third step is trimming. Replace the chuck corresponding to the size of the oil seal on the fully automatic trimming machine. Keep the oil seal in the slot. Adjust the inner and outer diameter tools. Just step on the two sides of the oil seal. It will be repaired neatly, and the oil seal is now close to a finished product.
The fourth step is that if it is a fluorine rubber oil seal, we will perform secondary vulcanization to make it more durable and bake it in the oven. Each step we take is just to make the oil seal more durable and extend its use for sale.
The fifth step is to put a spring on the oil seal. Most oil seals require springs. Use a specially customized thick carbon steel spring to reduce the wear of the oil seal rotation.
The sixth step is to wipe silicone oil on the oil seal to ensure the oil seal is tight. Brightness and durability, and dust is removed. In the process, burrs or problematic products are also removed.
The seventh step is packaging. Pack the oil seals into a roll of 10 pieces, or a separate package. At this point, the oil seals are all completed.
The oil seal is a very small thing. We will use 7 steps to complete its production process. Every step of our process is just to bring better products to customers. Feiyun Seals Factory has all the oil seals you need.
