“We’ve partnered with Zhenhua Stamping for over four years for custom stampings and standard fasteners used on photovoltaic equipment. They independently open molds based on our technical drawings, and can produce parts in 304/316 stainless steel, carbon steel and 65Mn spring steel. They handle small prototype orders and large-volume mass production equally well, acting as our trusted one-stop hardware supplier for PV projects.”
“Our company specializes in manufacturing photovoltaic power generation equipment, and all structural stamping accessories are purchased from Zhenhua. They provide full-range surface finishing solutions such as zinc plating, black oxide, HDG and Dacromet within the factory. We don’t need to cooperate with external electroplating vendors, which greatly shortens our overall procurement cycle for PV components.”
“Zhenhua’s IATF 16949 standardized full-process quality management brings us great peace of mind. Every batch of PV stamping fasteners comes with complete hardness and dimension inspection reports, fully complying with DIN, ISO and JIS international standards.
