Products of different properties of vacuum electroplating electric heating tubes also have different effects

Poor electroplating also has different effects on products of different properties. For example, cosmetic cosmetic defects can cause a product to not look as expected, but not functional failure. However, functional surface defects refer to the corrosion of the substrate of the product components during the use of the product, which is not allowed to exist in any surface-treated parts.

Under vacuum conditions, the atoms and molecules of the evaporated substance have fewer collisions with other molecules in the process of flying to the plastic product, and their activity in the gas is reduced. The chemical reaction between the molecules and the evaporation source material to provide the density, purity, deposition rate and adhesion of the film.

Vacuum electroplating electric heating tube to adjust the evaporation time

Because the surface of the plastic is not smooth enough, the surface of the workpiece directly electroplated is not smooth, the gloss is low, the metal feeling is poor, and some bad conditions such as air bubbles and blisters will also appear. After spraying a layer of primer, a smooth and flat surface will be formed, eliminating the generation of air bubbles and blisters in the plastic itself, thus showing the effect of electroplating.

Vacuum electroplating is a method of heating metal under high vacuum, melting and evaporating it, and forming a metal film on the plastic surface after cooling. The way to heat metal is to use the heat generated by electrical resistance. Yes, some use electron beams. In the evaporation process of plastic products, in order to ensure that the heat released when the metal cools will not deform the resin, the evaporation time should be adjusted.

The basic inspection items of the electroplated parts of vacuum electroplating electric heating tube include:

Electroplating means that in a salt solution containing pre-plated metal, the base metal to be plated is used as the cathode, and through electrolysis, the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal to form a plating layer, so that the electroplated parts can be anti-corrosion and improve resistance. A surface treatment method for abrasive resistance, heat resistance and enhancement of aesthetics.

The basic inspection items of electroplated parts include: film thickness, adhesion, solderability, appearance, packaging, salt spray test, etc. Vacuum plating is the practice of spraying a primer on the material before plating. Since the material is plastic, there will be air bubbles in the machine gas during the injection molding process, and moisture in the air will be sucked in when placed.
