High-Precision Zinc Alloy Mortise & Lever Door Handle OEM Manufacturing
Engineering & OEM Product Development
Shakti Architectural is a premier B2B contract manufacturer specializing in high-quality OEM product development and custom private-label programs for precision zinc mortise and lever door handles. As a trusted manufacturing partner to global hardware brands and major distributors, we seamlessly transform custom 3D CAD models, engineering blueprints, or physical benchmarks into market-ready architectural hardware collections. Our in-house R&D and tooling division leverages advanced CAD/CAM software to optimize part geometry, backed by rapid prototyping capabilities that validate fit, ergonomics, and structural integrity before mass production begins.
Precision Tooling, Die-Casting & Surface Preparation
To deliver top-tier consistency across multi-thousand-unit production runs, our in-house toolroom engineers hardened mold dies calibrated for tight dimensional tolerances (±0.05 mm). Mass production is executed inside our advanced high-pressure zinc die-casting facility (using certified Zamak/ZDC alloys), engineered to eliminate porosity, air pockets, and structural micro-fractures in handles, escutcheons, roses, and backplates. Following robotic CNC machining, precision threading, and automated edge-finishing, handles undergo multi-stage robotic grinding and mirror-buffing to ensure flawless surface uniformity prior to electroplating.
Export-Grade Finishing, Rigorous QA & Global Logistics
Engineered to exceed international architectural standards (including EN 1906 / ANSI BHMA Grade compliance benchmarks), our handles pass through an automated electroplating and PVD coating line. We offer an extensive spectrum of luxury architectural finishes, including Satin Nickel, Polished Chrome, Antique Brass, Matt Black, Gunmetal, and Satin Brass. Every production lot is governed by a rigorous 7-step quality assurance protocol—encompassing X-ray layer thickness testing, micro-tolerance gauging, spring-cycle torque fatigue tests, and ASTM B117 salt-spray chamber validation. Finished products are packaged in custom private-label branding with seaworthy container logistics padding, ensuring seamless, zero-friction supply chain delivery worldwide.
