Yamaha внедрила новый материал SMC, сокративший время литья моторов на 20%

Yamaha Motor adopts high-cycle SMC, cuts outboard molding time 20% KEY POINTS - Yamaha Motor, Yamaha Marine and Japan Composite develop high-cycle SMC for outboard motor top cowls - New material cuts molding cycle time 20% and is expected to lower molding-stage CO2 emissions 20% - Material has been used since 2025 as Yamaha Motor targets supply-chain carbon neutrality by 2050 Yamaha Motor Co. and group company Yamaha Marine Co. have jointly developed a paintable sheet molding compound, or SMC, material with Japan Composite Co. that reduces molding cycle time by 20% from conventional levels and has already been adopted for top cowls on Yamaha outboard motors, the companies said on July 16. The new "high-cycle SMC" material was first adopted in 2025, according to the release. Yamaha Marine, a Yamaha Motor group company, is responsible for producing the affected outboard motors. The 20% reduction was based on Yamaha Motor's March 2026 internal assessment. Yamaha Motor said the material lowers the heat energy required in the molding process. SMC is a thermosetting resin material that generally requires significant heat during molding. The companies said cutting molding cycle time by 20% also curbs energy consumption during production and is expected to reduce carbon dioxide emissions from the process by 20% versus conventional materials. The companies attributed the development to continued verification and optimization of both the material and manufacturing process. Emissions tied to gas combustion for steam generation and electricity use in molding fall under Scope 1 and Scope 2 greenhouse gas emissions. Scope 1 and 2 refer to direct emissions from a company's own operations and indirect emissions from purchased energy. Yamaha Motor Group is pursuing carbon neutrality across its full supply chain, including business activities, by 2050 under its Environmental Plan 2050. For Scope 1 and 2 emissions, the group has brought forward its carbon-neutrality target for manufacturing sites, including group companies, to 2035. The use of molded composite materials is common in marine and vehicle components where durability, formability and surface finish are important. In this case, Yamaha Motor positioned the new material as part of its broader effort to improve manufacturing efficiency while lowering emissions from production. © Copyright 2026 IBTimes JP.
