In-House Facilities · Turnkey Production

Eight production lines, from tooling to finished goods—all under one roof

Jintai's turnkey production flow covers tooling design and development, die-casting/stamping, injection molding, precision machining, painting and surface finishing, and final assembly—all completed in-house at our Group's Dongguan facility, Litai Hardware. Below is the equipment scale and daily output of each production line—this is the concrete basis for not having to source different parts from different suppliers.

Production line capability overview

Machine System	Qty	Best For
Die-casting line	17 machines	80–160-ton zinc alloy die-casting machines with automatic feeding; lock bodies, cylinders, keys, cabinet lock housings, etc.; daily output over 200,000 pieces
Stamping line	25 machines	5–400-ton electric/pneumatic/variable-speed/straight-side presses plus shearing machines; copper, iron, stainless steel, and sheet metal; daily output over 350,000 pieces
Injection molding line	15 machines	30–250-ton vertical and horizontal machines; PP, ABS, PU, POM, PVC, nylon; daily output over 60,000 pieces
Machining line	—	Grinding, drilling, tapping, turning, welding, polishing; average daily output over 800,000 pieces
Painting line	Conveyor line	Full-line painting equipment with antimicrobial coating capability
Tooling line	In-house	Lathes, grinders, milling machines, EDM, wire cutting; stamping/plastic/die-casting tooling made in-house for short lead times
Assembly line	—	Automatic cylinder pinning machines, laser marking machines, automatic machining centers plus inline inspectors; average daily output over 100,000 pieces

Why this matters to buyers

Eight production lines operating under one management system means three things: in-house tooling keeps development cycles and mold modification costs under control; having die-casting, stamping, and injection molding in-house means metal and plastic parts for the same lock don't need to be outsourced; and assembly lines with inline inspectors keep quality responsibility intact across the supply chain. For brand buyers, this is the physical foundation of a single point of accountability.
