How To Choose Electroplating Rectifier? - Liyuan plating ...

There are three requirements for choosing an electroplating power supply:

Kehong are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

First of all, it must meet the specifications required by the electroplating process, including the power of the power supply, waveform indicators, adjustable ranges of current and voltage values, etc.

Second is the reliability of the power supply itself, which mainly refers to the rationality and safety of the structure, circuit characteristics and heat dissipation methods, etc.

Third, consider the cost-effectiveness of its price.

Determining the plating variety and the size and power supply of all plating solutions is one of the most important tasks. In practice, there are two methods to determine the electroplating power supply: one is the volume current density method, which is determined based on the capacity of the plating solution; the other is the unit area current density method based on the electroplating area.

The so-called volumetric current density is to adjust the current intensity of the entire plating solution according to the larger current allowed per liter of plating solution, thereby determining the larger power supply and conventional output power to be used. Generally, copper plating is 0.2 ~ 0.3a/L, nickel plating is 0.1 ~ 2.5a/L, bright nickel plating is 0.3 ~ 0.35a/L, acidic zinc plating is 0.5 ~ 0.6a/L, and alkaline zinc plating is higher than 1.2A/L. Chrome plating 2 ~ 3a/L, taking bright nickel plating as an example, the maximum process current of 600L plating solution can reach 0.3A/L×600L=180A, so a 200A power supply can be selected.

The larger current can also be calculated based on the plating area. Take chrome plating as an example. If the plating solution is 600L, the maximum current density at 60°C is 100A/dm2, and the plating tank can plate 10dm2 when fully loaded, then the maximum output current of the required power supply is 100A/dm2×10dm2=A, that is, A and 18V should be configured rectified power supply.

   After the power of the power supply is determined. It is also necessary to select the waveform, cooling method, volume and anti-corrosion capability of the electroplating power supply according to the needs of the electroplating process and the conditions of the electroplating site, including cost factors.

Hello, here is my new dilema, always something to buy.

I hate to admit this but my culture for some reasons evryone wants a shiny ,bling, if you can call it that, firearm. Ive been learning how to polish, to a high luster. Ive been blessed that my local ffl/gunsmith is a 4th generation gunsmith. Ive been learning how to polish with leather, yep how colt used to do it in the old days, so interesting, but enough about that.

We got to talking, and want to split the bill and learn how to plate, basically nickle and eventually gold. Ive been looking at casewell plating, they seem to be the only ones with a class its an online class consisting of videos and literature. They sell a start up kit that includes a 3 amp rectifier, i know thats not enough. So the next step up is a 5 amp and then the jump to a 30 amp.

According to caswell the 5amp should be good for firearms like a full size .

Should I buy the rectifier from them or is there a better source, which should i get, i believe he told me there is a 300 dollar difference.

What are your thoughts over all with casewell and the online course?
