Surgical instrument Comprehensive surface treatment

Xinying medical instrument have a complete surface treatment production line,including ultrasonic cleaning, manual polishing, plasma electrochemical polishing, electrolysis, sandblasting, passivation and other surface treatment processes for medical devices.

1-Manual polishing

This process can not only remove the burrs and edges produced after machining, but also greatly improve the surface finish of metal parts.

2-Ultrasonic cleaning

Utilize the cavitation effect, acceleration effect and direct flow effect of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning.

3-Plasma electrochemical polishing

Nanopolishing is called plasma polishing. Nano polishing is an environmentally friendly polishing process.The characteristics of the polished product are mainly manifested in: reduced roughness, improved finish and precision, hard and durable, reduced notch sensitivity, smooth and tidy, reduced friction coefficient, reduced wear, etc.

4-Electrolysis

The technology of using a metal workpiece as an anode and performing electrolysis in a suitable electrolyte to selectively remove its rough surface and improve the surface finish is also called electrolytic polishing. Electropolishing increases corrosion resistance of stainless steel.

5-Sandblasting

The process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. , due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece, increasing it and coating Adhesion between layers.

6-Passivation

Passivation refers to the process in which metal is oxidized by strong oxidant or electrochemical method to make the surface into an inactive state, that is, passivation.
