Medical Ceramic Parts

The ceramic plunger adopts modern engineering ceramic material with super hard wear resistance, and can be assembled and formed by ceramic metallization bonding, welding, inlay and socket technology. It is an ideal substitute for similar metal pumps, and has been widely used in medical equipment, environmental engineering, petroleum, chemical and other industries.

Zhongwei Precision is committed to providing domestic and foreign customers with advanced Medical ceramic parts with high strength, high toughness, wear resistance, corrosion resistance and high temperature resistance. enterprise. With a variety of modern high-precision equipment, it has independently realized the completion of the entire production process of ceramic parts from ceramic powder preparation, green body molding, high temperature sintering to ceramic material finishing.

4. Available materials for ceramics:

It mainly produces finished ceramic rods, ceramic tubes, ceramic rings, ceramic plates, ceramic suction cups, ceramic blades and other special-shaped ceramic structures. The main ceramic materials are alumina, zirconia, silicon carbide, silicon nitride, and aluminum nitride ceramics. High temperature resistance, wear resistance, corrosion resistance, acid and alkali resistance, anti-magnetic, pressure resistance. And 3D printing, etc. are customized according to customer requirements.

Combined tube, its high wear resistance effectively resists material wear and impact.

Product Feature

(1) The ceramic plunger is made of high-performance technical ceramic materials, and is designed by sintering and isostatic pressing at a high temperature of 1600 °C. The product has the characteristics of corrosion resistance and high temperature resistance, no softening, no cracking, and no peeling during use. The long-term use temperature of alumina is within 1600 degrees, the use temperature of fully stabilized zirconia is within 2200 degrees, and the use temperature of boron nitride is within 2400 degrees. We strictly control each link from ceramic materials to product processing, and the processing accuracy adopts ISO2768m standard. To ensure reliable material performance.

(2) The microporous structure obtained by processing the working surface of the ceramic plunger has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump.

(3) The inner cavity surface of Medical ceramic parts adopts fluid structure without dead angle and groove. The surface of the inner cavity and the surface of the plunger are processed to a mirror surface by a high-precision inner and outer cylindrical grinder, and the outer surface is vibrated and polished, which is convenient for cleaning and disinfection.

(4) The structure of the pump body is finely sealed with the product structure, which is convenient for disassembly.

(5) This type of product has been tested for corrosion resistance, acid and alkali resistance, and its various indicators have reached the level of similar foreign products.

Zirconia ceramic rods have made a major breakthrough and development in the medical field. The recent news of the epidemic equipment has seen a new turn, and there are major improvements in the discovery of medical equipment. The Xiaoxiao Diagnosis and Treatment Ceramic Plunger Rod is assembled into the new coronary pneumonia pre-vaccination selection equipment, which is a booster for drug delivery. There will be nearly 100 in a new coronary pneumonia pre-vaccination selection equipment.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. spent more than two years to solve the problems of difficult to find materials and difficult to process, and successfully completed the independent research and development of products, and also created a complete set of product processing process and testing methods. The produced medical ceramic plunger rods fill the gap in the domestic industry. Alloy materials are also commonly used as plunger rods at home and abroad, but metal materials cannot avoid the risk of being corroded by acid and alkali solutions, and metal ions are easily dissociated into reagents, so special ceramic materials are the choice. Zirconia ceramic rods are also a very wear-resistant commodity. Since zirconia is professionally added to the porcelain components, this type of raw material has good wear resistance, and it is rarely used due to Damaged and deformed, or destroyed, those characteristics also make it have a good service life. People can get an excellent feeling when using such products, and they can also allow people to have better use effects. No matter which different products it is used in, it can also enjoy a good effect. What people can also see is that zirconia ceramic rods are also a very high lubricity component at this stage. This kind of raw material itself has a good degree of self-lubrication, so it is also All of them can produce stronger actual effects of operation and application, reasonably assist machines and equipment to improve their characteristics, and bring better use effects. Because of the superior performance of precision zirconia ceramic rod products, people love this product. It is also getting higher and higher, and has been well received by everyone.
