Best fit
Custom automation works best when the process can be defined before supplier selection.
China can be a strong source for custom automation equipment when the product geometry, cycle time, quality checks, operator workflow, and factory acceptance test can be described clearly. The wrong way to source custom automation is to ask broad supplier lists for a price without first defining the task.
A good special-purpose machine builder should ask technical questions before quoting: sample variation, tolerances, failure modes, changeover, utilities, controls standards, safety expectations, and maintenance access.
Custom automation equipment sourced from China
Assembly machines
Indexing tables, screwdriving, press-fit, dispensing, riveting, joining, insertion, and fixture-based assembly.
Test and inspection equipment
Leak testing, functional test, electrical test, vision inspection, force testing, barcode, OCR, and reject handling.
Feeding and handling systems
Bowl feeders, flexible feeders, conveyors, pick-and-place, part orientation, buffering, and transfer units.
Packaging and end-of-line machines
Labeling, counting, bagging, carton loading, case packing, check weighing, and palletizing support equipment.
RFQ scope for custom automation equipment
- Product drawings, samples, variation range, material, tolerances, and known defects.
- Current process video, manual steps, pain points, operator count, and target cycle time.
- Required quality checks, reject rules, data logging, traceability, and test record requirements.
- Preferred PLC, HMI, servo, pneumatic, sensor, camera, and robot brands.
- Factory acceptance test method, sample quantity, test duration, and pass/fail criteria.
- Installation country, documentation language, training needs, spare parts, and remote support expectations.
How to check Chinese custom machine builders
| Check | What to ask for | Why it matters |
|---|---|---|
| Comparable machines | Videos, drawings, line layouts, installed year, and cycle-time proof. | Similar delivered equipment is stronger evidence than a general capability claim. |
| Engineering team | Mechanical, electrical, PLC, HMI, vision, and commissioning headcount. | Custom automation risk often appears when engineering is outsourced or thin. |
| Controls ownership | PLC backups, HMI files, electrical drawings, manuals, and remote diagnostics plan. | Your plant needs to maintain the machine after installation. |
| FAT process | Written test plan, samples, runtime target, reject criteria, and punch-list method. | The FAT is the strongest leverage before shipment. |
