About Yuhuang Electronic Technology
Founded in 1998, Dongguan Yuhuang Electronic Technology Co., Ltd. is a leading industry-trade integrated enterprise specializing in the R&D, production, and sales of high-precision hardware fasteners. We are dedicated to the innovation of non-standard hardware fasteners and the mass production of precision components complying with GB, ANSI, DIN, JIS, and ISO standards.
Integrated Production Ecosystem
Cold Heading Excellence
Equipped with multi-station cold heading machines and 3-die 6-blow units. We handle specifications from M1 to M22 with extreme structural integrity.
Precision Nut Production
Specialized nut cold heading and cam machines for knurled nuts and embedded nuts ranging from M2 to M16.
High-Precision CNC
Advanced sliding head machines and CNC centers controlling tolerances within 0.02mm to 0.03mm for complex cylindrical parts.
Stamping & Washers
Continuous die stamping for parts under 1.0mm and single punch for 3-5mm thickness, including spring, flat, and square washers.
The Journey: From Raw Material to Perfection
Material Selection & Inspection
We source premium steel, stainless steel, and alloys. Every batch undergoes element analysis via X-ray fluorescence to ensure 100% compliance with REACH and ROHS.
Precision Forming (Cold Heading)
Using high-speed automated machines, wire is transformed into the screw's basic shape, ensuring grain flow optimization for maximum strength.
Thread Rolling & Machining
Precision thread rolling ensures smooth, accurate threads. For custom components, our CNC centers provide surgical-level accuracy.
Heat Treatment & Surface Finishing
Controlled heating enhances hardness, followed by specialized coatings (zinc, nickel, etc.) for superior corrosion resistance.
AI Optical Sorting & Full Inspection
10+ optical sorting machines detect defects at speeds of 600+ pcs/min, followed by manual full inspection for 100% aesthetic perfection.
