Upgrading Green Manufacturing Processes and Energy-Saving Optimization for Plastic and Die-Casting Molds

Release time:

2026-06-11

Green manufacturing has become the core direction of mold industry transformation and upgrading. The production and manufacturing of plastic molds and precision die-casting molds are gradually moving away from the traditional high-energy-consumption and high-loss mode, realizing energy saving, carbon reduction, quality improvement and efficiency enhancement through process optimization and structural iteration. In the field of plastic molds, the industry focuses on optimizing the structure of hot runner systems and cooling systems. Valve gate hot runners replace traditional cold runners to reduce plastic waste and improve raw material utilization. The optimized conformal cooling water channels shorten the cooling and shaping time of products, reduce the heating and cooling energy consumption of injection molding equipment, and improve production rhythm. Meanwhile, the application of mold surface nano-coating technology reduces the use frequency of release agents and lowers pollutant emissions during production. For die-casting molds, optimizing the gating and exhaust structures reduces molten metal waste and defective rate during die-casting. New energy-saving heat treatment processes replace traditional high-temperature long-time heat treatment, reducing processing energy consumption and production time while ensuring the mechanical properties of molds. In addition, the industry has gradually established a full-life-cycle mold recycling system to recycle and reprocess waste mold steel and runner materials to realize resource recycling. The equipped intelligent energy consumption monitoring system collects real-time production energy data, accurately locates energy loss links, and continuously optimizes production parameters. The implementation of a series of green processes not only reduces the comprehensive cost of mold production and product forming, but also conforms to industrial low-carbon development requirements, promoting the sustainable and environmentally friendly upgrading of the mold industry.
