State-of-the-Art Manufacturing & Uncompromising Quality Control

We do not outsource our core quality. From raw material CNC machining to full-line FAT testing, Tengzhuo’s in-house manufacturing capabilities ensure 100% precision engineering and reliable on-time delivery for every packaging system.

Inside Our 5,000+ ㎡ Manufacturing Facility

Precision CNC machining workshop at Tengzhuo
Workshop 01

Precision Machining

The birthplace of accuracy. Equipped with high-end machinery to independently mill, lathe, and shape non-standard core components with strict tolerance control.

Full-Line Integration

A massive, dedicated space designed to closely replicate your factory floor. We connect up to 50-meter-long turnkey lines for synchronized debugging and FAT testing.

Heavy-Duty Machining for Micron-Level Precision

The lifespan and stability of a packaging machine depend entirely on the precision of its underlying parts. We invest heavily in our own machining assets to guarantee exceptional durability.

01

5 Sets of Premium CNC Centers

Delivering true micron-level precision. We independently machine critical components like filling pump cylinders, custom starwheels, and seaming chucks to ensure minimal mechanical deviation.

02

Heavy-Duty Metal Forming

Utilizing our in-house shearing (1 set) and bending (1 set) machines, we precisely cut and fold thickened 304/316L stainless steel plates, creating rock-solid, vibration-proof machine frames.

03

Seamless Sanitary Welding

Advanced laser welding techniques create smooth, gap-free joints, eliminating microbial blind spots and ensuring strict compliance with pharmaceutical and food hygiene standards.

48-Hour Full-Line FAT Protocol: Zero Bugs Before Shipping

We never ship theoretical setups. Before any machine leaves our facility, it must successfully complete a rigorous 48-hour continuous Factory Acceptance Test (FAT), perfectly simulating your actual production flow using your own containers and materials.

Container Sorting in FAT
Step 1

Container Sorting

Continuous unjammed feeding of empty bottles.

Precision Filling in FAT
Step 2

Precision Filling

High-speed dosing with <±1% accuracy and zero drips.

Capping and Sealing in FAT
Step 3

Capping & Sealing

Applying consistent torque and reliable airtight seals.

Labeling Integration in FAT
Step 4

Labeling Integration

Seamless handoff for wrinkle-free labeling.

Inspection and Reject in FAT
Step 5

Inspection & Reject

Dynamic checkweighing and metal detection verification.

End-of-Line in FAT
Step 6

End-of-Line

Automated case packing and robotic palletizing without bottlenecks.

If the line drops a single bottle or stutters during the 48-hour continuous run, it does not ship.

5S Quality Management: The Foundation of Fast Delivery

International buyers demand consistency. Our strict adherence to the Japanese 5S management system is the secret behind our rapid lead times, consistent assembly, and high-standard machine hygiene.

SEIRI

Sort

Distinguishing between necessary and unnecessary tools, instantly freeing up workshop space for efficient, large-scale assembly.

SEITON

Set in Order

Every mold, bolt, and PLC component has a strictly designated and labeled location. This eliminates searching time, dramatically speeding up our manufacturing and delivery cycles.

SEISO

Shine

Maintaining a spotless, dust-free assembly and testing zone. We guarantee absolutely minimal foreign contaminants enter your machine’s sensitive pneumatic or fluid pathways.

SEIKETSU

Standardize

Transforming cleanliness and order into rigorous, daily standardized operating procedures (SOPs) for every single worker.

SHITSUKE

Sustain

Cultivating a strict, uncompromising engineering culture. Our team is disciplined to build every machine as if it were a surgical instrument.
