Modern prototype manufacturing has shifted from simple model-making to complex "Digital Twins." Chinese manufacturers are now integrating CAD/CAM data with AI-driven casting simulations to predict structural weaknesses before a single drop of molten steel is poured.
Western enterprises are moving beyond "cost-only" sourcing. Today, the demand is for Manufacturing Resilience. JUNLONG Machinery addresses this by providing a vertically integrated supply chain—from mold design to final CNC machining.
With the rise of EVs and aerospace requirements, the focus has shifted to high-strength alloys and corrosion-resistant stainless steel (304/316). We provide advanced material testing to ensure prototypes meet localized industrial standards globally.
Founded in 2014 and nestled in the industrial hub of Weifang, Shandong, JUNLONG Machinery Co., Ltd. spans a massive 60,000 square meters. We are not just a factory; we are a high-tech ecosystem capable of producing 20,000 tons of precision castings annually.
Our expertise covers the entire spectrum of carbon steel, alloy steel, and stainless steel casting. With a team of 200+ dedicated professionals, including 30+ senior engineers, we bridge the gap between initial prototype concepts and mass-market finished parts.
