> stainless steel plates manufacturers analysis plates to make the difference between the water electroplating and vacuum plating sign making commonly used is the electroplating, plating, water is usually used in the plating bath electroplating, and vacuum plating, vacuum plating mainly includes vacuum ion plating include vacuum evaporation, sputtering and ion plating several types.
Both electroplating way we sign that is commonly used in production process, so they all have what difference?
A, stainless steel plates manufacturers to introduce the characteristics of the vacuum plating: 1.
Vacuum coating of metal film layer is very thin,
As a general rule, be 0.
01 ~ 0.
To strictly replicate bei the shape of the workpiece surface.
Working voltage is not very high,
, easy to operate, but more expensive equipment.
Evaporation pan bottle volume small, chrome, which less, low production efficiency.
Limited to the low melting point than tungsten metal (
Such as aluminum, silver, copper, gold, etc. )
Act the role of plating.
For the high quality requirements, usually before plating on the surface of the plating to render oil to compensate for the workpiece surface defects.
Vacuum coating can be plating a variety of plastic, such as: ABS, PE, PP, PVC, PA, PC, PMMA, etc.
Two plating, stainless steel plates manufacturers introduce water features: water relative to the vacuum plating electroplating is relatively simple, from the device to the environment are u have a vacuum ion plating demanding, which is widely used in sign making, hydropower has a weakness, but the plating material is single, only plated ABS and ABS + PC material (
The effect is not very ideal material plating)
And ABS material only 80 ℃ heat resistance poor performance, which makes its application range are restricted.
And vacuum plating can reach 200 ℃, for use in the high temperature parts can be processed in the plating.
Like the wind, the wind ring use PC material, all of these components have resistance to high temperature of 130 ℃.
General requirements resistant to high temperature parts, do should be in the vacuum plating zui after spraying a layer of UV oil, so that the surface is glossy and products are high temperature resistant, and guarantee the adhesion at the same time.
3, stainless steel plates manufacturers analysis the advantages and disadvantages of vacuum plating and electroplating water: 1.
Vacuum plating cost is higher than water plating, because if the vacuum plating UV oil, however, its adhesion is very poor, not through the TEST, and water electroplating is much better than vacuum plating.
Therefore, in order to guarantee the vacuum plating adhesion, all need special spraying processing follow-up, cost of course.
Water plating color is drab, generally only the silver, gray, silver, gun color, golden, black chrome color, semifinished chromium and so on a variety of seven color is powerless.
And vacuum plating can solve the problem of seven color.
Coating material of electroplating generally USES 'hexavalent chromium', it is environmental protection material.
To the requirement of 'hexavalent chromium' has the following: the European Union: 76/769 / EEC: it is prohibited to use;
1000 PPM so strict requirements, some domestic manufacturers have begun to try to use 'trivalent chromium' instead of 'hexavalent chromium';
The vacuum plating coating material widely used, easy to conform to the environmental protection.
Vacuum plating sign high wear resistance, vacuum plating to sign the metal feels strong, high brightness, and can pass the test of friction.
Electroplating water sign is less in terms of wear resistance.
