What is precision plating

Precision plating (including some processes related to the chemical surface film-forming reaction in the liquid phase) can give various metal and non-metal devices a beautiful appearance and excellent abrasion resistance and wear resistance, and can make the surface of the device obtain more This special function makes it a new type of functional material, and it can even be used as a means to form some metal matrix composite structural materials.

Precautions for electroplating of precision parts

Because the plating layer has a certain thickness, after the surface treatment of the part, it will inevitably cause the change of the size of the part. Generally, the dimensions and tolerances of the parts specified on the design drawings refer to the final dimensions and tolerances of the parts. If the parts do not have matching requirements, electroplating or electroless plating is still feasible on the final dimensions of the parts; if the parts have higher precision, The fit gap after assembly cannot accommodate the thickness of the plating layer and its deviation relatively, so plating on the final size of the part is detrimental to the assembly and working performance of the product. In order to solve the problem of size matching of parts with matching requirements after plating, it is necessary to negotiate with the design and process departments of the parts to determine the pre-plating process dimensions of the parts, and reserve the thickness of the plating layer and the size deviation of the plating in advance. It must be noted that it is not feasible to reserve the thickness of the plating layer and not reserve the thickness deviation that may occur during plating.

Precision plating | the role of electroplating additives

In order to improve the performance of the plating solution and the quality of the coating, a small amount of certain organic (or inorganic) substances are often added to the plating solution, which is an additive. Additives, the result is a sponge-like deposit. After adding the additives, the coating is dense, fine and bright.

Precautions for surface treatment of precision electroplated aluminum alloy

The hard anodic oxide film on the surface of aluminum and aluminum alloy has high hardness and excellent wear resistance. It is a common method to improve the wear resistance of aluminum parts. In order to improve the service life of The quality anodized film layer has a relatively large thickness. Therefore, after the aluminum parts are hard anodized, the final size of the parts will change significantly. This rule is usually followed, which is the increase in the final size of the parts, which is roughly equal to the film 1/2 of the layer thickness, as shown in the figure. This value is widely used to estimate the size change of aluminum parts after hard anodization.

Frequently Asked Question

Do you have any question?

Products plated by PPC are integral in some of the manufacturing world’s most complex assemblies. Our metal plating finishes are found in safety-critical devices, such as ABS modules, drive-by-wire controls, commercial and military aircraft, and implantable medical devices.

Masking tape is used for precision electroplating to cover the electroplated parts that are not electroplated.

Precision electroplating usually means that the original tolerance of the parts that need to be electroplated (oxidized) is small, generally within 0.01mm. On the premise of meeting the product functionality, after electroplating (oxidation), the size of the parts can still meet the original tolerance requirements .
