A few years ago, I opened a factory specializing in the production of metal parts. Due to the relatively strong market demand, friends are also more concerned about, and soon business has improved, orders are gradually booming. Later, I expanded my factory building and machinery and started to make some inventory products to meet the needs of some customers to get products quickly. But a big problem with this change made me very troubled.

A large amount of metal workpieces produced in my factory began to corrode and rust in a short time. Rusted workpieces are not required by the customer, and safety performance falls short of the standard. This vicious cycle has caused a backlog in my factory inventory and major problems in the capital chain. I began to actively seek some help to solve the rust problem of metal parts, but many technical staff told me that the main reason for metal rust is electrochemical corrosion and air oxidation. The pure metal or the lively metal is mainly the result of the oxidation reaction between the metal surface and the oxygen in the air. Metal oxides, that is, rust, are formed on the metal surface. If the metal contains more impurities, these impurities will form a chemical primary battery with the metal, electrochemical corrosion occurs, thereby oxidizing the metal to produce metal oxides. Therefore, metal rusting is unavoidable. What we can do is not to stop it, but to improve its anti-rust performance and prolong salt spray time.

In the following more than one year, I began to actively try some rust-proof methods. Through the understanding of the market, it was found that there are many ways to prevent rust such as electroplating, cathodic electrophoresis, hot dip galvanizing, and Dacromet protection. In general, Dacromet has the best corrosion resistance. First of all, it is an environmentally friendly process with little waste liquid waste residue in the process. Second, compared with electroplating, hydrogen embrittlement is not available. The best anti-corrosion and anti-rust time is long. The longest salt spray time can reach 3000 hours, which can fully meet the anti-corrosion and anti-rust requirements of our products. So I began to purchase Dacromet equipment, but because I did not understand this equipment, I followed the advice of a factory salesperson and purchased their Dacromet equipment and coating fluid. The first use of Dacromet equipment is a large foreign trade order, mainly to help them carry out workpiece rust processing. Later, it was found that the effect of anticorrosion and rust was not achieved at all, and that a lot of metalworking parts rusted, and I suffered huge losses and also offended this large overseas customer. During that time, the factory was almost dying. It was later relieved by the help of a friend.

After I spent a period of time, I restarted my business. Choosing a good Dacromet coating facility is still a very important issue, but I have become very cautious at this time, and I have been exposed to a number of decisions that have not always been at ease and do not make purchases. After a chance coincidence, I visited Changzhou Junhe Technology Co., Ltd. and found that they were the first production unit in the Dacromet industry to propose a “turnkey project”, so they had a strong interest. Through several times of understanding and communication, we know that Dacromet coating equipment produced by Changzhou Junhe Technology Co., Ltd. has high cost performance and low energy consumption, and has a good reputation and exemplary role in the industry. Can consider the problem from the customer's point of view and provide a complete set of complete solutions, without having to consider the after-sales problem. So I purchased their Dacromet equipment and found that not only has a good anti-corrosion anti-rust effect, metal parts of the anti-corrosion time has been greatly extended. Recently there was more good news. Through my perseverance, overseas major customers agreed to give me another chance to cooperate. This time, the goods were sent to customers in a perfect manner on time, and the foreign trade market was activated again. My factory finally came back to life.
