Hefei Weidi is a leading domestic manufacturer and the third globally to achieve mass production of electrochromic glass. It is also a drafter of industry standards and has built the first related production line in China. The company employs core processes such as magnetron sputtering, focusing on all-solid-state inorganic electrochromic glass products. These products boast advantages such as low carbon emissions, energy saving, low driving pressure, and no power consumption memory. Their products cover fields such as construction, high-speed rail, cruise ships, and new energy vehicles. They can iteratively upgrade traditional glass, contributing to dual-carbon goals. The company's technological approach aligns with leading international manufacturers, and the industry has high technical barriers and promising development prospects.

Weidi's technological and production advantages

High barriers to entry in manufacturing equipment

Electrochromic glass mass production equipment is a capital-intensive project (accounting for 70% of the project's capital investment), is a core secret, and is not sold to overseas competitors. Nearly 70% of the equipment in the production line needs to be customized. Weidi has independently completed the design and debugging of two generations of production lines and has joined forces with domestic manufacturers to achieve the localization of equipment outsourcing and processing. Compared with the customized models of overseas competitors in Europe and Japan, the cost is lower and the cycle is shorter.

Production process barriers

Electrochromic glass consists of six layers of nano-semiconductor thin films. Hundreds of process variables are involved, and these variables interact with each other; finding the optimal process window takes years. VDI has complete control over the formula, process flow, and technical parameters of its smart glass products.

Construction of domestic industrial chain

We have developed a complete domestic supply chain for production equipment and raw materials; we have signed exclusive supply contracts for core materials and equipment; we have a wide range of other suppliers to choose from, with no exclusive suppliers and no special gases or materials.

A well-developed patent portfolio

Weidi has completed the initial patent layout in the field of electrochromic technology, with a total of 61 applications and 41 approved (including 5 invention patents). The number of patents approved ranks first in the domestic industry, laying a solid foundation for the company's long-term development.
