Recently, multiple overseas new energy vehicle enterprises have placed repeat bulk orders for lightweight customized parts. Relying on integrated services including 3D printing, CNC precision machining and silicone low-volume casting, Jiaheng delivers full-process concept car models and interior structural components without multi-supplier coordination. Traditional mold manufacturing takes 2-4 months, while our solution completes full vehicle models within 15 days to cut R&D costs, leading to steady month-on-month growth of overseas repeat orders.
