Overview
Assembly automation succeeds when part presentation, fixtures, and quality checks are engineered together.
For assembly projects, the supplier is not only building a machine. They are deciding how parts are fed, located, joined, tested, rejected, changed over, and maintained. A good Chinese assembly automation supplier should understand the full operator workflow and the product variation that will appear in real production.
Common assembly automation projects sourced in China
Screwdriving and fastening
Automatic screw feeding, torque control, depth checks, missing screw detection, and traceability.
Press-fit and joining
Servo press, pneumatic press, force-distance monitoring, staking, riveting, clipping, and insertion.
Dispensing and sealing
Glue, grease, sealant, gasket, potting, and bead inspection with fixture control.
Test and inspection
Functional test, leak test, electrical test, machine vision, barcode, OCR, and reject handling.
Assembly automation RFQ requirements
- Part drawings, tolerances, sample range, assembly sequence, and defect examples.
- Current manual process video and target cycle time by station.
- Feeding method assumptions for each part: bowl, tray, flexible feeder, manual load, or conveyor.
- Fixture, poka-yoke, quality check, reject, and rework requirements.
- Controls standards, safety guarding, operator access, changeover, and maintenance expectations.
How to validate assembly automation suppliers
Ask for similar machines, fixture design examples, active builds, FAT records, controls architecture, and service documentation. For assembly work, weak fixture design or part feeding assumptions can break the project even if the mechanical frame looks professional.
