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. That means we can take responsibility for the whole line — and respond in days, not weeks.

Multi-axis synchronous fastening

Dual / quad / six-axis platforms drive cycle times below 3 seconds per station — perfect for compressors, motor housings, and power tools.

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, multi-station sequencing — we ship a working prototype in 4-6 weeks.

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, multi-axis drives — machined on our own high-end CNC centers to micron tolerances. In-house manufacturing is why we can prototype fast, hold quality, and stand behind the whole line.
