In terms of market demand, domestic customers have shifted from passive demand in the past few years to active demand. In the past few years, customers were able to choose what kind of equipment was available in the market on their own, mainly due to poor technical capabilities of domestic test chambers and relatively expensive foreign brands, with very little room for choice. Most of the customer's needs are also in their infancy, and they demand to simply copy foreign practices. So there is a high demand for standard containers. From the perspective of test box manufacturers, imported brands adopt * or domestic joint venture assembly; Many manufacturers have emerged in China, and their technology is in the stage of imitation and learning. In terms of after-sales service, domestic and foreign manufacturers provide relatively simple equipment maintenance services.

In recent years, customer demand has been increasing from a technical perspective, with product technology requirements tending towards high-tech and comprehensive functional development. Previously, temperature, humidity, vibration, salt spray, rain, salt spray, and other tests were conducted separately. Now, multiple functions are required to be integrated into one box. The level of technical requirements has also increased, and the performance indicators have also become higher. After more than 20 years of development, the domestic testing chamber industry has also accumulated a group of technically strong enterprises and talents. Capable of undertaking and fulfilling projects with special functions. In the standard container market, customers still tend to prefer imported brands, while general customers tend to buy domestic brands and are more sensitive to prices. In terms of non-standard test chambers, it is a different scenario. Currently, foreign brands have almost no technical research and design capabilities in China, or it takes relatively long for customer needs to be fed back to foreign countries. Slow time, high quotation. The customer is also concerned about after-sales service issues. Therefore, customers now prefer domestic manufacturers with technical strength. Manufacturers can quickly respond to customers' special requirements and new demands, and share resources with foreign manufacturers in terms of components. Pre sales and after-sales service are faster and better. Customer costs are also relatively low.
