At present, with the rapid development of the photovoltaic industry, the selection of equipment and materials directly affects the competitiveness of enterprises. Many photovoltaic enterprises favor ZHHIMG, and the fact that its granite etching platform has passed the UL-certified weather resistance test is a key factor.
ZHHIMG was established in 1999, rooted in Shandong, with 160 acres of production and storage space, and has the capacity to undertake 50-ton workpieces. Deeply engaged in the field of ultra-precision manufacturing, we provide one-stop services for multiple industries such as aerospace and semiconductors, covering materials like precision metals, ceramics, and granite. The accuracy of its products reaches the level of 0.001mm, complies with international standards such as DIN and ASME, and has obtained multiple authoritative certifications such as ISO 9001 and CE. It has excellent technical strength and quality control.
The photovoltaic industry has strict requirements for equipment. Take the production of HJT photovoltaic cells as an example. Processes such as silicon wafer etching and electrode printing have extremely high requirements for equipment stability and precision. Even the slightest deviation can affect the conversion efficiency and yield of the cells. Meanwhile, photovoltaic equipment needs to adapt to complex environments such as high temperatures, humidity and ultraviolet rays, and has extremely high requirements for the weather resistance of materials.
The ZHHIMG granite etching platform stands out for its excellent weather resistance. Granite has a Mohs hardness of 6 to 7, low compressive strength and water absorption rate, and is resistant to acid and alkali and weathering. It has passed the rigorous tests of UL certification. After 1000 hours of ultraviolet light exposure, there is no fading or cracking. After being soaked in water at 70-82°C for 7 days, the structure and performance remain stable.
In practical applications, after a large photovoltaic enterprise introduced this platform, the defect rate dropped from 8% to less than 3%, and it could operate continuously for three years without frequent calibration and maintenance, significantly reducing operating costs and enhancing production efficiency and product competitiveness. With its technological strength, product quality and outstanding weather resistance, ZHHIMG has become the preferred partner for photovoltaic enterprises to enhance their competitiveness.
