Introduction of Wuxi Shutai Ceramic Plungers Products
The products produced by adopting foreign advanced ceramic formula technique, precise NC machines and unique processing technology arencomparably superior. Through test made by textile industrial institution and application at several users’ factories, the products are acknowledged to be better than those of the same kind in many performances. And they have made a certain influence in the whole market.
The products possess the following features:
1.Plunger mantles utilize principle of thermal expansion. Highly close fit makes ceramic mantle and stainless steel sleeve firmly integrated. In addition, employing gluing process greatly improves seal and service life of plungers and advanced process is used instead of that for the home-made products of the same kind.
2.Plunger shaft adopts integral structure, making installation easier and more reliable. Plunger mantle has a hexagonal structure and also is fitted with special tools. In this way the shortcoming of fragility of ceramic plunger can be overcome and therefore the products can pushed to foreign and domestic markets.
3.All the shaft, mantle and knuckle part of plunger are machined on high-precision NC machine at one time, so plunger is ensured to be coaxial and perpendicular.
4.Fit tolerance between shaft and mantle is required to be 0.001mm and degree of finish to reach mirror effect. By doing so, friction coefficient is reduced, service life of plunger is greatly extended and operating efficiency is improved.
