What factors cause electroplating failures in electric heating tubes

For electronic equipment manufacturers, electroplating processing is essential during electronic processing activities. Various problems may arise during electroplating processing, which can cause inconvenience to production. There are many types of electroplating processing faults, and now let's understand the influencing factors of electroplating faults:

1. Impact of raw materials

In electroplating production, it is common for faults to occur due to improper use of raw materials. Objectively looking at the raw material market in the electroplating field, there is a mixed situation between good and bad additives, from anode materials and chemical materials to various additives, and even additives with the same name and purpose cannot be used interchangeably.

2. The Influence of Physical and Chemical States of Plating Materials

When there are coating defects, the emphasis is often placed on finding the cause from the electroplating process. In fact, the processing state of the parts before electroplating, the chemical composition and metallographic structure of the materials have a significant impact on the electrodeposition process, and even affect the success or failure of the processing. Rich zinc in zinc aluminum alloy parts can cause difficulties in electroplating; Hard chromium plating on alloy steel parts after grinding is prone to cracking; Carbon segregation during heat treatment of steel parts can cause excessive corrosion during the electroplating process.

3. The impact of electroplating process specifications

The electroplating production process has a long and numerous processes, and there are many factors that can affect the occurrence of faults. Such as unclean pre-treatment, poor cleaning, ineffective hanging tools, electrolyte composition imbalance and impurity pollution, uncontrolled operating conditions, and poor production environment. The cause of the malfunction often lies in one or two details of the above influencing factors.

4. The impact of improper human operation

Among the five factors that affect product quality (operators, equipment, materials, process methods, and production environment), people are the first. Many electroplating failures are related to the professional skills and work responsibility of the operators. If the cleaning operation does not meet the requirements of the operating standards; Lack of professional knowledge and incorrect addition of chemical raw materials.
