The key significance of electroplating equipment selection to ensure the quality of electroplating products

release time:

2021-09-15

The selection of plating equipment is of key significance to ensure the quality of electroplating products and improve production efficiency. The program controllable gantry electroplating line, annular automatic electroplating line and barrel plating automatic production line, as well as supporting peripheral equipment such as rectifier, filter are introduced in detail. machine, heat exchanger, ultrasonic cleaning machine and additive automatic replenishing machine, etc.

The key significance of electroplating equipment selection to ensure the quality of electroplating products

Electroplating automatic production line: rack plating rack plating automatic production line is divided into annular mechanical or hydraulic automatic production line and linear production automatic production line

Advantages of early loop lines:

1) High degree of automation, high efficiency, reduced labor intensity, and fewer operators;

2) Lever type vertical lift, high utilization rate of plating tank capacity;

3) The exposure time is short, the workpiece runs smoothly, and the time for each arm is about 20 ~ i00s;

4) It is suitable for electroplating light-duty mechanical annular electroplating production line with high quality requirements of coating, large batch, single shape and mature technology (commonly known as hanging fish type). Because of its cheap price, light weight, easy maintenance and high output, it has a great market.

The advantages of linear electroplating automatic line:

1) The degree of automation is high, the efficiency is high, and the labor intensity is reduced. fewer operators;

2) It is suitable for the electroplating of heavier parts and large objects, as well as the electroplating of parts of different shapes and batches;

3) It is convenient to change the driving working condition. Flexible electroplating time control, suitable for electroplating of various production processes;

4) The electroplating quality is excellent and stable. It is suitable for processes with thicker coating requirements.

Barrel plating automatic lines also have two categories: annular mechanical or hydraulic automatic lines and linear gantry automatic lines. Ring-shaped mechanical bell drum suitable for inclined automatic loading and unloading

High-speed electroplating equipment (sheet, wire) and selective electroplating equipment follow the development of economy and the progress of electronic electroplating. Automatic line for high-speed electroplating production. The demand for selective electroplating production lines has increased. Most of them are undertaken by companies with greater technology and manufacturing capabilities.

Auxiliary equipment around electroplating production line

The electroplating power supply is the most important auxiliary equipment in the electroplating production process. Silicon rectifiers and thyristor rectifiers are still widely used in China, which are divided into voltage regulators, magnetic saturable reactors and thyristors. Silicon rectifiers for electroplating and silicon controlled rectifiers are both low voltage and high current, generally 12v (18v for chrome plating), and silicon rectifiers with thyristor voltage regulation from 100a to 20000a only have a good transition shape when the load is high. Electroplating power supplies with voltage regulation and stable current density are also being promoted and applied.

Electroplating solution filtration equipment The filter is one of the key equipments related to the quality of electroplating products.

Both filter elements and filter cloths can be produced. When choosing, pay attention to the production of "real" filtration precision filters. There are still some problems:

1) The specification and high reliability of the filter machine used for chrome plating and electroless nickel plating have yet to be studied. Special plastics such as polyvinylidene fluoride (pvdf) and chlorinated polyvinyl chloride (cpvc) and related parts must be introduced. No Manufactured chrome filter from polypropylene plastic.

2) High quality magnetic pump to be developed

3) The filtration accuracy provided by the factory now needs to be confirmed by scientific means. The special filter cloth, filter bag and filter paper are still to be produced.

4) The shaft seal material of the centrifugal filter needs to be improved, and the problems of wear resistance and leakage prevention should be solved.

5) The electroplating process is changing with each passing day, and the auxiliary equipment must keep up, such as the special chemical degreasing filter for pretreatment, which can not only separate the oil slick on the liquid surface, but also absorb the suspended oil droplets. It will greatly improve the quality of electroplating products and improve the phosphating film. Quality is great.

Ultrasonic equipment uses the cavitation effect of ultrasonic waves, which can greatly speed up the degreasing and rust removal of the pretreatment, shorten the processing time, and improve the degreasing and rust removal effect.

Heating and cooling equipment Traditional electroplating heating methods mostly use steam or electric heating. Currently, diesel burners are used to heat hot water tanks. In summer, chillers are generally used. Ensure that acid bright copper and bright tin plating work at standard operating temperatures.

Electroplating solution automatic management system The solution automatic management system is the dynamic detection and control device of the solution composition and process parameters

Electroplating and coating composite process application equipment - cathodic electrophoresis With the improvement of the decorative and corrosion resistance requirements of electroplating products, many products require electrodeposition of a layer of paint after multi-tone electroplating. application

Electroplating equipment management: management of electroplating hangers, management of electroplating auxiliary equipment, management of anodes, management of electroplating auxiliary equipment, electroplating production site, electroplating production scale, electroplating production equipment, management of electroplating main equipment.
