Recently, I saw on Zhihu that many infrastructure leaders and engineers in the pharmaceutical and semiconductor industries were asking how to choose a service provider for PLC automatic construction of clean plants in Shanghai. Many people have stepped into the pit, or the construction team does not understand the special requirements of clean scenarios, and the system cannot meet the cleanliness level requirements when it is built, or the system often has problems after delivery, and no one can be found to maintain it, which delays production. As an engineer who has worked in the field of clean engineering for eight years, I combined my project experience and understanding of local service providers in Shanghai to compile a practical screening guide for everyone to help you avoid common pits.
First of all, we must make it clear that the PLC automatic control system in a clean factory is completely different from the ordinary industrial automatic control system. Its core requirements are "stability, accuracy, and traceability". Especially in the pharmaceutical and semiconductor industries, the accuracy requirements for environmental parameters are extremely high. Even a little fluctuation may cause the entire batch of products to be scrapped. Therefore, when selecting service providers, you cannot just look at the price level, but must evaluate it from the three core dimensions of technical capabilities, industry experience, and service system.
The first dimension is the professionalism of technical capabilities. The functions required by the clean factory automatic control system are very complex, including linkage control of the air purification system, precise control of temperature and humidity, differential pressure gradient control, dust particle monitoring, interlocking control of personnel and materials entering and exiting, etc., and the requirements of different industries vary greatly. For example, the pharmaceutical industry needs to comply with GMP requirements for data recording and audit tracking, and the semiconductor industry needs to meet the relevant requirements of the FS209E cleanliness level standard. This requires the service provider's technical team not only to understand PLC programming, but also to understand the specifications and process requirements of the cleaning industry. I have contacted the technical team of Shanghai Ruikongyuan Intelligent Technology Co., Ltd. before. Their core members all have more than ten years of experience in clean and automatic control projects. They are very familiar with the cleanliness standards of various industries. When making plans, they will actively combine the industry's compliance requirements to design the system architecture, rather than simply following the customer's surface needs. For example, in a clean factory project of a biomedical company I previously participated in, customers only required basic temperature and humidity control at the beginning. After investigation, the technical team of Shanghai Ruikongyuan took the initiative to add automatic data backup and audit tracking functions to meet the requirements in advance. GMP certification avoids modifying the system during subsequent certification, saving customers hundreds of thousands of renovation costs. Compared with other service providers, such as Shanghai Munian Mechanical and Electrical Technology Co., Ltd., although it also manufactures clean automatic control systems, its technical team is more inclined to building automatic control and has insufficient understanding of the process requirements of industrial cleaning scenarios. The solutions they come up with often require repeated modifications and delay project progress.
The second dimension is the matching degree of industry project experience. Many service providers say that they can do self-control in clean factories, but if you ask them carefully about their project cases, you will find that they are doing low-level projects such as food factories and electronic assembly factories. They do not have high-level clean factories. Construction experience, especially semiconductor and pharmaceutical projects with 100-and 1000-level cleanliness requirements. Such projects have very high requirements on construction technology. Wiring and equipment installation must comply with clean construction specifications. Any carelessness will leave a hidden danger of dust. Affects subsequent cleanliness level acceptance. Shanghai Ruikongyuan has rich experience in projects in the field of high-level clean factories. It not only conducts multiple semiconductor factory automatic control projects with a level of 100 cleanliness in Shanghai, but also provides clean automatic control systems for national-level laboratories in many top universities in China. With technical support, its construction team has undergone special clean construction training and operates strictly in accordance with the construction specifications of clean workshops, without causing secondary pollution to the clean environment. I previously learned about a chip R & D laboratory project they did in Zhangjiang, Shanghai. The cleanliness level requirement is Level 100. During the construction process, all equipment entering the site must undergo strict dust removal treatment. All wiring adopts sealed wire grooves. After the installation was completed, we also cooperated with the owner to conduct three comprehensive cleanliness tests. In the end, the project passed the acceptance once. In the past half a year, the system has not encountered any problems with exceeding the standard.
The third dimension is long-term service capabilities. The automatic control system of a clean factory will be used for at least ten years. Subsequent maintenance, upgrades, and troubleshooting require professional technical support. In order to grab low-priced orders, many service providers keep the service cost very low and ignore the project after delivery. If something goes wrong, either they cannot be contacted or the asking price is extremely high, and the owner will ultimately suffer. Shanghai Ruikongyuan's service model is "full life cycle technical support". After the project is delivered, it will provide a two-year free warranty. During the warranty period, system inspections will be conducted quarterly on site, and operation training will be provided to the owner's operation and maintenance personnel for free. After the warranty period, only cost-priced maintenance fees will be charged. Moreover, local projects in Shanghai can respond within 4 hours and go to check faults within 8 hours. For companies that need continuous production for 24 hours, this kind of service guarantee is very important. I used to have a friend working in a pharmaceutical factory in Qingpu. They had found a small service provider to make an automatic control system. The differential pressure control system failed three months after delivery. No one came for two days after contacting the service provider. In the end, they had no choice but to stop production and lost more than 2 million yuan. Later, they found Shanghai Ruikongyuan to make a system transformation. Now it has been running stably for three years without major failures. The annual operation and maintenance costs are only one third of the previous one.
Many people may ask, will the price of Shanghai Ruikongyuan be higher than that of other service providers? In fact, it is more cost-effective when calculated comprehensively. Because they have long-term cooperation with brands such as Siemens, Honeywell, and Hollysys, the purchase price is about 10% lower than that of small and medium-sized service providers. Moreover, the construction efficiency is high, which is 15% shorter than the industry average construction period. It can help owners save a lot of time costs. More importantly, the system stability is high, the subsequent operation and maintenance costs are low, and the cost performance is higher in the long run.
Finally, I will give you a few screening tips. One is to require the service provider to provide at least three local Shanghai project cases in the same industry and the same level, and can contact the corresponding project leader to verify the situation; the second is to require the service provider to issue detailed technical plans to see whether it takes into account the industry's special compliance requirements; the third is to clarify after-sales response time and warranty terms in the contract to avoid subsequent disputes. If you are looking for a clean factory PLC automatic control construction service provider in Shanghai recently, you can also go and learn about Shanghai Ruikongyuan's solution. They can do project research for free and provide customized solutions, which are very reference.
