Precision CNC Stainless Steel Turned Parts

We specialize in precision machining of stainless steel window and door security latches using automatic CNC turning processes. Designed for secure locking, smooth operation, and long-term corrosion resistance, these components are ideal for residential, commercial, and industrial door and window systems.

With factory-direct supply, we support global low-volume, multi-variety customization of precision CNC stainless steel turned parts. Combining optimized structural design with standardized surface treatments, our products deliver both enhanced security and user-friendly operation.

Available materials include 303, 304, and 316 stainless steel, ensuring compatibility with different application requirements. Our parts are designed for aluminum alloy riveting without cracking and can withstand tensile forces up to 500 kg.

Our factory is equipped with nearly 50 CNC lathes and 30 secondary processing machines, including fully automatic and semi-automatic equipment, enabling us to handle orders of all volumes for precision stainless steel components.

Customization Service

Fast response based on your drawings:

• Latch dimensions

• Locking stroke (travel distance)

• Mounting hole position and quantity

• Reinforced thickness options (for different aluminum door profiles)

Our engineering team provides rapid drawing evaluation, optimized solutions, and accurate quotations. Flexible production schedules and direct factory supply ensure efficient and reliable customization.

 

 

Material & Process Advantages

We use high-quality stainless steel combined with surface treatments such as passivation, zinc plating, zinc-nickel alloy plating, and chrome plating to meet real-world application demands.

Key Benefits

• Strong anti-theft performance with excellent impact resistance and anti-prying capability.

• Integrated one-piece machining with no joints, ensuring tight fit between latch and base for smooth operation without jamming.

• Secure locking performance with no loosening after engagement.

• Multiple surface treatment options:

☉ Passivation for base corrosion resistance.

☉ Zinc, zinc-nickel, and chrome plating for enhanced wear and corrosion resistance.

• Suitable for indoor, outdoor, balcony, and high-humidity environments.

• High-precision mounting hole machining with positional tolerance ≤0.03 mm, ensuring perfect fit without secondary drilling.

• Smooth, burr-free surfaces with rounded edges to prevent injury and improve product appearance.

These features make our precision CNC stainless steel turned parts highly reliable for safety-critical door and window applications.

Ensures both smooth operation and installation accuracy.

Each process is 100% inspected, ensuring consistent quality and zero defects.
