As the core power conversion component of the turbocharging system, the working principle of the scroll disk is based on the precision-designed involute scroll surface, which drives the disk to rotate at high speed through the kinetic energy of the exhaust gas flow, and efficiently converts thermal energy into mechanical energy. Relying on independent innovation of low pressure casting and gravity casting technology, combined with directional solidification control technology, Hersin ensures the geometric precision of the scroll tooth profile and the micro-densification of the material, which can maintain stable airtightness and dynamic balance under high temperature and high pressure environments, and significantly improves the efficiency of the turbine operation and the reliability of the system. Ningbo Hersin scroll disc adopts low-pressure gravity casting process, based on A356-T6 high-strength aluminum alloy directional development, specially designed to meet the extreme working conditions of turbocharging system.<\/p>\n\n\n\n

application scenario<\/h2>\n\n\n\n

1. Turbocharging system optimization<\/h3>\n\n\n\n

Dynamic components designed specifically for gasoline\/diesel turbochargers to enhance exhaust gas drive efficiency by 12-15% through precision scroll surfaces, helping to achieve National VI emission standard requirements. Suitable for BorgWarner, Honeywell and other mainstream supercharger platforms.<\/p>\n\n\n\n

2. Thermal management of new energy vehicles<\/h3>\n\n\n\n

Applied to PHEV\/HEV electric supercharger system, the lightweight design (58% weight reduction compared with traditional steel parts) significantly improves the energy density, and with heat-resistant coating effectively solves the problem of thermal degradation of the motor system.<\/p>\n\n\n\n

3. Commercial vehicle durability upgrades<\/h3>\n\n\n\n

The enhanced version developed for long-distance working conditions of heavy trucks has been verified by Cummins ISX series bench through the directional grain control technology, which enables the parts to maintain >100,000km warranty cycle even under the continuous high backpressure environment.<\/p>","protected":false},"excerpt":{"rendered":"
