Technology empowerment in non-standard fields (friction blocks for lawn mowers)

A North American garden machinery brand plans to develop an electric zero-emission lawn mower, but traditional friction materials are prone to overheating and failure under low-speed and high-frequency braking. Dingchi and its customers formed a special team to develop a "low-metal + nanographite" composite friction block. After passing a 3,000-hour durability test, the product's friction coefficient stability increased by 30%, and the noise value was reduced to below 55dB. This model now occupies 18% of the US high-end electric garden equipment market.
