Established in 2012 for industrial fastening automation

Lock every screw right.
Scale every line fast.

We build automatic screw fastening systems — from handheld feeders to fully integrated assembly lines — for manufacturers in 3C electronics, home appliances, automotive, and other industrial applications. Our Shenzhen team provides project evaluation, manufacturing, installation, training, and after-sales support for qualified projects.

Product Matrix

Six fastening platforms. One engineering partner.

From a single handheld feeder to a fully automated multi-station line, choose the platform that fits your throughput, footprint, and screw spec — or let our engineers design a non-standard solution.

Industries Served

14 industries. One screw at a time.

From smartphone hinges to EV battery packs, our installed base spans every screw-bearing product line on the modern factory floor.

Why Chisu

A manufacturing partner — not a parts vendor.

We engineer feeding mechanisms, fastening modules, and vision systems in-house, then evaluate the right configuration with your product and process requirements.

Multi-axis synchronous fastening

Dual-, quad-, and six-axis platforms can be evaluated for repeating fastening patterns, product geometry, and required throughput.

Vision-guided ±0.02mm accuracy

Integrated CCD vision auto-locates screw holes — defeats incoming part variation, mixed-model lines, and micro-screws down to M1.0.

Servo closed-loop torque & angle

Dual-loop servo control records every screw's torque, angle and timestamp — meets automotive, medical, and aerospace traceability standards.

Full-line integration

Conveyor, pallet, rotary, robot — we wire the fastening cell into your existing PLC, MES, and SCADA stack.

Non-standard challenges

Deep holes, tight spacing, oblique angles, and multi-station sequencing are evaluated against the actual part, screw, and process requirements.

In-house manufacturing

10,000m² factory in Shenzhen — CNC, sheet metal, assembly, fatigue testing — all under one roof.

Chisu factory workshop
Engineered & Built in Shenzhen

We make the core parts ourselves.

Feeding mechanisms, fastening modules, vision brackets, and multi-axis drives are supported by in-house machining and fabrication capability. Each proposal is reviewed against the relevant project requirements.
