At Sunmy Hardware, customization isn’t just a service—it’s our foundation. Our 70-strong team of engineers, technicians, and trade specialists thrives on translating client requirements into tangible products. Whether you provide a detailed CAD drawing, a physical sample, or even a conceptual sketch, our product development team initiates a collaborative process: first analyzing technical feasibility, then optimizing designs for manufacturability, and finally delivering a tailored production plan with transparent timelines.​

This client-centric approach has made us a trusted partner for businesses ranging from startups to Fortune 500 companies. Recent projects include:​

  •  A precision lathe-turned component for European automotive sensors, meeting ISO 9001 standards with 0.01mm tolerance​
  • Custom stamped metal brackets for North American consumer electronics, optimized for cost and weight reduction​
  • Injection-molded plastic enclosures for Southeast Asian medical devices, certified for biocompatibility

Comprehensive Manufacturing Ecosystem

What truly distinguishes Sunmy Hardware is our end-to-end production capabilities, housed in a 5,000㎡ facility equipped with state-of-the-art technology:

  • Casting: Specializing in sand casting and die casting for large metal components (up to 50kg), ideal for industrial machinery and automotive parts.​
  • CNC Lathe & Machining: 20+ high-precision CNC machines handling complex geometries in materials like aluminum, stainless steel, and titanium.​
  • Stamping: Progressive die stamping for high-volume metal parts (10,000+ units/month), serving electronics and appliance industries.​
  • Injection Molding: 15 injection molding machines (50-300 tons) producing custom plastic components with tight dimensional control.

This vertical integration eliminates reliance on third-party suppliers, ensuring quality consistency, faster lead times (as short as 7 days for prototypes), and flexible scaling from 100 to 1,000,000+ units.

Serving Global Industries with Precision
