The Zhejiang Provincial Investment Project Online Approval and Supervision Platform published a notice on November 6: Zircon Technology (Huzhou) Co., Ltd. has filed an enterprise investment record for its "Annual 600,000-Piece Laser Additive Manufacturing Metal-Ceramic Composite Brake Disc Coating Project" (2611-330552-04-01-226014, Huzhou South Taihu New Area Management Committee Government Service Center). The project enters the automotive brake disc wear-resistance enhancement segment via the laser additive manufacturing route, representing a volume-production deployment of laser directed energy deposition (L-DED) and laser cladding in the surface engineering of automotive components. If the laser additive route for metal-ceramic composite materials used in automotive brake disc coatings reaches a scale of 600,000 pieces per year, it will drive steady consumption of wear-resistant metal-ceramic powders and laser cladding equipment. Value for buyers: this volume-production signal for laser additive coatings on automotive brake discs corresponds to segmented demand for wear-resistant metal-ceramic powders and L-DED equipment, and provides a basis for tracking equipment and powder supplier selection.
