As a new polishing process, plasma polishing is a trend in stainless steel polishing. If we can make good use of plasma polishing will save us a lot of time and costs.
PVD and CVD are the most commonly used surface treatment methods for tools and moulds, CVD is based on chemical vapour deposition and PVD is based on physical vapour deposition, as they differ in principle, the final coating results are different and each has its own focus in application.
Electrolytic polishing has great advantages over traditional polishing, low cost, small footprint, can polish complex workpieces, has unmatched advantages over traditional polishing.
PVD stands for Physical Vapour Deposition. PVD coating refers to a thin film deposition technique whereby solid materials are sputtered or evaporated in a vacuum environment and deposited as pure materials or alloy components to form a coating on a substrate.
There are many different types of ion sources used in vacuum coating. The main ones are: high frequency ion sources, arc discharge ion sources, Kaufmann ion sources, radio frequency ion sources, Hall ion sources, cold cathode ion sources, electron cyclotron ion sources, anode layer ion sources, inductively coupled ion sources and probably many other types of ion sources that have not been mentioned.

As a new polishing process, plasma polishing is a trend in stainless steel polishing. If we can make good use of plasma polishing will save us a lot of time and costs.
Plasma is at high temperature and pressure, polishing salt water soluble, at high temperature and pressure, the electron will be out of the nucleus and run out, the nucleus formed a positively charged ions, when these ions reach a certain number of times can become plasma state, plasma state energy is very large, when these plasma and to polish the object friction, instantly will make the object to achieve the effect of surface brightness. Any side of the workpiece can be polished. The practical application of the general mobile phone casing, for example, basically all mobile phone manufacturers require stainless steel mobile phone casing for the surface without scratches, no lines, no white spots of the mirror effect. Polishing process is generally from the stamping out of fully formed products, the follow-up process is generally laser, electroplating, oil spraying, etc.. Polishing is generally done by hand, or a combination of hand and plasma polishing.
Hand polishing means hand polishing, relying on the friction of the product and the hemp, thread and cloth wheel. The disadvantages of the hand polishing process are obvious. Hand polishing efficiency is very slow, workers are also very high wages. And polishing is a great harm to human body industry. The management of polishing workers is a major headache, as workers are free-spirited and highly mobile. Plasma polishing reduces the pressure on the environment for our customers.
Semi-automatic and fully automatic environmental protection plasma polishing equipment with automatic control, simple operation and easy maintenance, reducing staff and labour costs. It also saves the customer a lot of material consumption caused by traditional polishing methods such as manual polishing, electrolytic polishing and chemical polishing. The frictional effect of plasma polishing on the surface is generally to remove 1~2 filaments. Stamping marks and surface orange peel cannot be removed. A combination of manual polishing and plasma polishing is used.
This means that the surface embossing and orange peel is removed by hand opening at first. The very deep spar pattern is removed using a very fine wire wheel pattern. At this point the wire wheel pattern is removed by plasma polishing. The final result is a mirror-bright surface without any grain, with r-angles on the angles of the surface. The inside of the workpiece is as polished and bright. This piece uses this plasma polishing mainly in the removal of manual polishing lines, less a cleaning procedure, increased aesthetics, high rate of finished products.
As a result of the manual opening and manual polishing and finishing time costs are basically the same, combined with plasma polishing to save some costs, the main effect is to greatly improve efficiency and improve the finished product rate.
For products with laser and etched surfaces: laser and etched products can leave yellow marks, stains and reduce the gloss of the surface. With plasma polishing, the laser and etched pattern is maintained intact and any surface can be polished to remove stains, yellow marks and increase brightness. This greatly increases the aesthetics.
Mobile phones and other digital products internal parts: general product is the finished product for the punch out, some require internal parts to do processing. The effect is to de-cloak and de-burr.
The products made of stainless steel are mainly card slots, line slots, line boards, etc. Due to the internal parts are generally extremely irregular and complex, hand polishing basic can not deal with, the use of ion polishing can be very effective to go to the cloak, to burr, the corners to produce rounded. This allows the parts to work well together and greatly reduces friction with the lines. A special product in the interior is the slide rail, some of which are designed with obvious grooves and cannot be polished in many places because they cannot be effectively controlled in size by manual processing. The use of plasma allows for a very good control of the smoothness.
