In recent years, the development and application of drug-eluting stents is considered a revolution in the field of cardiovascular interventional therapy. With the popularization of vascular stents in interventional medicine, the preparation techniques of functionalized coatings are increasingly diversified. Among many methods, atomization spraying plays an increasingly important role as an emerging technology. Systematic research on it is used to guide the development of vascular stent coating preparation process, increase process reliability, achieve coating quality optimization and Reduce R&D costs.

1. Definition of atomization spraying

Atomization spraying is a spray that converts a liquid into fine particles in a vacuum or ambient gas. When the compressed air is mixed with the liquid, the liquid is broken down into small particles. Nozzles are used to generate an atomized spray that passes through an orifice in a high-pressure and controlled manner.

Atomized spray is ideal for a variety of coating, humidification, lubrication, gas cooling/conditioning, humidification and atomization applications.

2.Ascend atomization spraying equipment

In recent years, the medical industry has developed rapidly, but the workpieces of medical machinery are small, the surface treatment requirements are high, and the parts with complex shapes are typical characteristics of the medical machinery industry. As a special industry related to life, the entire surface treatment requires strict and special requirements, so It is necessary to choose a self-atomization spraying supplier with good technology. A professional atomization spraying manufacturer can not only make the medical machinery industry obtain good product quality, but also make the medical machinery industry even more powerful.

Guangzhou Ascend, which has many years of experience in the research and development of atomization spraying equipment, is committed to combining atomization spraying technology with the coating preparation of vascular stents for the atomization spraying system used for the surface treatment of small devices, so as to guide process development and optimize the coating. quality purpose. Guangzhou Ascend wave is researched according to the route of physical and mathematical modeling, fluid mechanics simulation, experimental detection and analysis, process development and application, and finally successfully developed a medical atomization spraying equipment for vascular stents.

3. Advantages of Ascend atomization spraying equipment:

Ultrasound minimizes product clumping or material clumping.

Low speed spray reduces overspray and waste.

.Ascend atomization spraying equipment is constructed from medical grade materials and is designed to be robust, abrasion and corrosion resistant.

Fine, uniform, 5-50 micron size fluid atomization.

The medical atomization spraying equipment developed by Guangzhou Ascend can solve the problem of restenosis caused by uneven spraying. As medical device technology evolves, Ascend will continue to design unique medical spray coating solutions to improve patient safety and provide the highest quality medical device coatings on the market.
