TPR Upgrades Engine Parts Production Facilities to Boost Global Manufacturing Efficiency

TPR Co Ltd is moving forward with a major modernization program to strengthen its core engine parts manufacturing business by upgrading production facilities across multiple product segments. The investment focuses on improving operational efficiency while ensuring that existing manufacturing activities continue without disruption. The company is introducing advanced production equipment to replace aging manufacturing lines, allowing it to improve productivity, maintain product quality, and reinforce its long-term competitiveness in global markets. These initiatives form part of TPR's broader strategy to support future demand for engine components while optimizing manufacturing performance.

TPR Modernizes Piston Ring Production

The company's piston ring business will receive significant investment, with the objective of increasing productivity by approximately 20–30%. This improvement will mainly be achieved by replacing older production lines at manufacturing facilities in Japan with new, more efficient equipment. TPR's Nagano Factory, located in Okaya City, Nagano Prefecture, serves as the company's mother plant and will undergo production line modernization while continuing manufacturing operations. This approach enables TPR to enhance manufacturing efficiency without interrupting product supply to customers.

Cylinder Liner Business Expansion

TPR, which holds the largest global market share in cylinder liners, will also advance the modernization of production facilities by introducing high-efficiency manufacturing lines both within and outside Japan. The company intends to improve manufacturing capability while supporting long-term competitiveness in global engine component markets. These facility upgrades are expected to strengthen operational efficiency and maintain consistent production quality across multiple manufacturing locations.

Focus on Growth Markets

Outside Japan, TPR plans to strengthen manufacturing facilities in markets where engine-powered vehicles are expected to retain meaningful market demand in the coming years. The company specifically identified India and Brazil as important regions for future investment. By improving production efficiency in these locations, TPR aims to preserve its leading market position while remaining competitive in environments characterized by strong pricing pressure and increasing competition.

Investment in Sintered Parts Production

Alongside its engine parts modernization strategy, TPR is evaluating additional investment opportunities for its sintered parts business. The company is considering production facility investments at its Gifu Factory in Kani City, Gifu Prefecture, as well as manufacturing plants located in China, Korea, and Vietnam. These planned investments are intended to improve manufacturing capability and support the company's long-term production strategy across its international operations.
