Define the current process
Collect process videos showing manual steps, labor count, pain points, product drawings, sample variation, known defects, and target cycle time. Suppliers need to see the actual problem, not a summary of it.
Custom machine sourcing
Custom Automation Equipment from China
For production challenges that standard equipment can't solve: assembly stations, test systems, feeding and orientation, fixtures, inspection, packaging, and special-purpose machines built to your exact process.
When custom automation makes sense
Custom automation works when your process is clear enough to test and prove.
China has a deep supplier base of machine builders, fixture shops, controls engineers, vision specialists, robot integrators, feeder manufacturers, and packaging equipment builders. That depth is valuable only when you can define your task well enough for suppliers to prototype and validate it.
We help you translate your production process into a quote-ready specification, then search for builders with proven experience in similar equipment instead of relying on catalog claims or generic capabilities.
How to get quality supplier quotes
The best supplier search starts before you send RFQs.
Define the acceptance test
Write out what the machine must prove during factory acceptance testing: runtime capabilities, good parts acceptance, bad parts rejection, changeover speed, documentation completeness, and operator error recovery.
Define support expectations
Clarify installation country, preferred component brands, PLC/HMI standards, manual and spare parts requirements, remote access needs, training scope, and warranty process.
What separates good quotes from weak ones
Good suppliers write about the hidden work, not just the visible machine.
Weak custom automation quotes list components and features but skip the real risk areas: part feeding, fixture design, reject handling, sensor placement, HMI workflow, maintenance access, and fault recovery paths.
Good Chinese suppliers explain what's proven in their experience, what's new for this project, and what requires sample testing before they commit to performance.
Common risks in custom automation projects
What usually breaks custom automation projects.
Part variation is underestimated
Perfect samples pass during demonstrations. Normal production variation jams feeders, defeats fixtures, or creates false rejects that weren't anticipated. Good suppliers test with your actual production parts and variation range.
Cycle time is guessed
Quoted speed often ignores loading time, inspection time, reject handling, changeover procedures, and operator interaction. The machine's theoretical speed and real production speed are different.
Controls are treated as an afterthought
Your production facility needs PLC backups, electrical drawings, alarm logic, and maintainable HMI screens that work after the machine ships and the supplier support ends. Controls aren't accessories.
FAT is too soft
A short demonstration with clean samples isn't sufficient proof. The supplier should demonstrate real samples, real fault conditions, and clear acceptance criteria that matter to your operation.
