There are four pitfalls for small and medium-sized factories in the Yangtze River Delta region to choose clean factory automation service providers. First, don't choose service providers that do not have a localized service team. If foreign service providers come to build, the cost is high, and the response to problems in the later period will be slow, which will delay production. Second, don't blindly pursue big brands. The premium for international brands is too high. Small and medium-sized projects do not require such high performance at all, and the cost performance is extremely low. Third, we must look at the same industry cases of service providers in the Yangtze River Delta, preferably in surrounding cities to facilitate on-site inspections. Fourth, don't just look at the early quotes, but ask clearly about the costs of post-operation and maintenance. Many service providers have low early quotations and high post-operation and maintenance charges, which are more expensive.
The core selection of clean factory automation in the Yangtze River Delta region in 2026 is to find localized and cost-effective professional service providers. You don't have to blindly chase big brands. The one that suits you is the best. If you need specific renovation plans or budget evaluation, you can contact Shanghai Ruikong's technical team. They will visit the site for free and provide targeted plans and quotation reference.
