The company describes itself.

is a professional manufacturer specializing in aluminum and zinc alloy die casting, integrated with in-house tooling, CNC machining, surface finishing, and assembly services. With manufacturing roots dating back to 1992 and formal establishment as Mingxin in 2003, we have over 30 years of experience serving global OEM and ODM customers. Located in Ningbo, China, one of the most important manufacturing and export hubs, Mingxin operates as a one-stop solution provider for precision metal components. We focus on delivering stable quality, controlled tolerances, and reliable lead times for medium-to-high volume production projects. Core Manufacturing Capabilities 1. Die Casting (Aluminum & Zinc Alloys) Mingxin is equipped with a full range of cold-chamber and hot-chamber die-casting machines, covering tonnages from 100T to 800T, enabling us to handle both small precision parts and larger structural components. We commonly work with materials such as: • ADC12 / AlSi9Cu3 / AlSi12 (Fe) • Zamak 3 / Zamak 5 • Other customized aluminum or zinc alloys based on application requirements Our die-casting process emphasizes: • Stable mass production • Optimized gating and venting systems • Reduced porosity and deformation • Consistent dimensional control 2. In-House Tooling & Mold Engineering Tooling is one of Mingxin's core strengths. All molds are designed and manufactured in-house, allowing full control from concept to mass production. Our tooling capabilities include: • Mold design & DFM analysis • MAGMA mold-flow simulation • EDM (sinker & wire-cut) machining • Precision mold assembly and trial runs By keeping tooling in-house, we help customers reduce development risk, shorten lead times, and optimize part structure and cost at an early stage. 3. CNC Machining & Precision Processing Mingxin operates 150+ CNC machining centers, including 4-axis machining centers and CNC turning lines, supporting high-precision secondary processing after die casting. Key capabilities: • CNC milling, turning, drilling, tapping • Multi-axis machining for complex geometries • Tolerance control up to ±0.01 mm • Automated production lines for stable repeatability This allows us to deliver ready-to-assemble parts, not just rough castings. 4. Surface Finishing & Secondary Processes To meet different functional and aesthetic requirements, we offer a wide range of in-house and partner-supported surface treatments, including: • Deburring & polishing (manual and robotic) • Shot blasting / sand blasting • Powder coating & spray painting • Anodizing, electrophoresis, passivation • Laser marking & silk printing These processes are widely applied to outdoor, industrial, and high-reliability components. Quality Control & Inspection Quality is integrated into every stage of our production process. Mingxin follows standardized quality systems and strict inspection procedures to ensure product consistency and reliability. Our quality capabilities include: • ISO 9001 / ISO 14001 / IATF 16949 certified systems • Coordinate Measuring Machines (CMM) • X-ray inspection for internal structure • Air-tightness and leakage testing • Process traceability via ERP system For high-requirement projects, we support PPM control below 50 and long-term stable production. Our Advantage as a Manufacturing Partner What sets Mingxin apart is not only equipment, but process integration and engineering collaboration. • One-stop manufacturing under one roof • Strong engineering support at early project stages • Stable quality for long-term cooperation • Clear communication and fast response • Experience with international customers and standards We do not aim to be the cheapest supplier, but a reliable long-term manufacturing partner.
