Custom automation machinery

Buyers must provide a detailed Product Requirement Document (PRD). Key technical specs include cycle time (tact time), positioning accuracy (typically ±0.02mm for high-precision tasks), and payload capacity. Ensure the supplier specifies the brands of core components; high-quality builds should use recognized brands like Siemens or Mitsubishi for PLCs, and SMC or Festo for pneumatic components to ensure global availability of spare parts.

For cross-border procurement, compliance is non-negotiable. Ensure the machinery carries the CE Marking for the European market or meets UL/OSHA standards for the United States. Specifically, verify adherence to ISO 12100:2010 for machine safety and IEC 60204-1 for electrical safety. Request functional safety certifications for emergency stop systems and light curtains.

Since physical visits may be difficult, implement a Virtual FAT via high-definition live streaming. Require the supplier to run the machine at 100% load for at least 4-8 hours continuously. Document the Mean Time Between Failures (MTBF) during the trial and demand a video manual covering operation, calibration, and common troubleshooting steps before final payment.

Ensure the system architecture is modular, allowing for future upgrades or capacity expansion. The software should support OPC UA or MQTT protocols for seamless integration into your existing MES (Manufacturing Execution System) or ERP. Confirm that the supplier provides the source code or unencrypted PLC programs so your local engineers can perform minor adjustments without relying solely on the vendor.

The biggest risk is specification misalignment. Unlike off-the-shelf products, custom machinery requires constant communication. Use Made-in-China.com's Secured Trading services to protect your deposit. Another risk is shipping damage; ensure the contract specifies vacuum packaging and IPPC-certified wooden crates to prevent corrosion and physical impact during maritime transit.

Negotiate a milestone-based payment structure: 30% deposit, 30% after successful FAT, 30% before shipment, and 10% as a retention fund payable after 3-6 months of successful operation. For after-sales, prioritize suppliers who offer remote diagnostic capabilities (VPN/Router access) and guarantee a 24-hour technical response time.

Confirm the Incoterms clearly; DAP or DDP is often preferred for complex machinery to ensure the supplier handles the intricacies of delivery. Ensure the supplier provides a detailed foundation drawing and utility requirements (voltage, air pressure, floor loading) at least 30 days before arrival. Inquire if the supplier can send a commissioning engineer or if they have local service partners in your country.
