How much do you know about the 6 manufacturing processes of oil seals? At present, the manufacturing technology of oil seal is developing towards full automation, semi automation, high efficiency and energy saving. Dongsheng seal tells you that dshmfcom will be able to see the oil seal (seal ring) into a fully automated road in the near future, and the oil seal industry in our country, from the whole, is mostly in the first level of foreign 60s and 70s (so-called pure hand stage), and then the production equipment of oil seal. Although the technology is not up to the level of foreign countries, it will not lose foreign countries.
Today, let's take a look at the 6 widely used oil seal manufacturing processes and equipment abroad.
1. oil seal (seal ring) production process mixing: in foreign oil seal production process, rubber mixer has been widely used. Automatic weighing, mixing, automatic feeding, automatic welding, mixing and rubber discharging, with high production efficiency and good quality of rubber making.
2. semi-finished products manufacturing process of oil seal: precision preforming machine is a semi manufactured machine widely used abroad. Its characteristics are the precise weight of the semi-finished product, the geometric switch regularity, the high production efficiency, the saving of the rubber material and the high qualified rate of the product. It is also a necessary means to effectively realize the high temperature and rapid mould pressing vulcanization process. Some seals manufacturers have introduced the equipment in China, but most oil seal manufacturers still use cutting machine and manual cutting of semi finished products.
3. high efficiency vulcanization technology and equipment for the production process of oil seal: the development of oil seal vulcanization technology and equipment is mainly high temperature (180 to 200 c or higher), and can be vulcanized in a short time (1 to 2min). As a result, the automatic vacuum vulcanizing machine and injection machine are widely used to mechanized and automate the operation units, shorten the operation time, improve the utilization rate and labor productivity of the equipment.
4. oil seal (seal ring) production process skeleton surface treatment: generally automatic phosphating treatment, in the process can be strictly controlled.
5. new structure mold for the production process of oil seal: the more commonly used rip die in foreign countries, the mold is installed on the template, the mould can be automatically opened, the product is automatically removed and the edge of the rubber can be ripped out by hand.
6. mechanization of the process.
