About

Turning "precision" into a standard you can trust

Qinglan Technology is a factory-based enterprise focused on precision metal parts manufacturing, serving demanding industrial customers over the long term with stable processes and data-driven quality management.

10 yrsPrecision machining expertise

Company Profile

From a single drawing,
to production-ready precision parts

We focus on CNC machining, CNC turning, custom non-standard structural parts and sheet metal bending, covering the full manufacturing chain from one-off prototyping to volume delivery. Our team brings together experienced process engineers and frontline machining technicians, emphasizing "process first, data speaks."

For demanding scenarios such as semiconductor equipment, medical devices and automation lines, we insist on process control to ensure batch-to-batch consistency, making precision a repeatable standard rather than a one-time coincidence.

Core Values

How we treat every part

These principles run through every stage of review, machining and delivery.

◎

Precision First

Drawing tolerances are the baseline; critical dimensions are controlled throughout. We would rather inspect one more time than let an out-of-tolerance part slip through.

⇄

Process Collaboration

We engage at the design-review stage, identifying hard-to-machine structures early and using better process solutions to reduce cost and risk.

⛉

Reliable Delivery

Transparent scheduling and clear milestones — we deliver on the agreed timeline and provide traceable inspection data with each shipment.

Our History

Every step of steady growth (sample timeline)

Founding

Starting with precision turning

Began with CNC turning, focused on stable volume machining of shaft and rotational parts.

Expansion

Adding machining centers

Added multiple CNC machining centers, expanding milling capability for complex structural parts.

Systematization

Building a quality system

Adopted the ISO 9001 quality management system and equipped CMM and other inspection equipment.

Integration

Four processes in synergy

Integrated CNC, turning, custom parts and sheet metal bending into one-stop precision manufacturing.

Today

Continuous upgrades

Introducing five-axis equipment and digital control, targeting higher precision and shorter lead times.
