Before you compare prices, compare these nine engineering specifications — cycle rate at your format, changeover time, product handling method, board tolerance, and more.
Nine specifications that decide real-world performance
Price lists look similar. Line performance does not. Across hundreds of case-packing installations, we have seen the same nine specifications separate a reliable line from a chronic stoppage machine.
**1. Cycle rate at your format.** A packer rated at 20 cases/min with one product may deliver 12 with yours. Ask for the cycle rate at your case size, product weight and pattern. We quote FAT-validated rates and stand behind them.
**2. Changeover time and method.** Tool-free, recipe-driven changeover under 10 minutes matters more than peak speed when you run more than three SKUs. Count changeovers per shift, not just speed.
**3. Product handling architecture.** Flexible pouches need robotic or side-loading handling. Rigid jars tolerate drop packing. Choose the architecture for your product family, not the cheapest available.
**4. Board and blank tolerance.** Machines that reject imperfect corrugate will stop your line. Servo-driven forming and compliant tooling absorb board variance that fixed heads cannot.
**5. Case squareness.** A case that leaves the packer twisted jams the sealer and palletizer. Check for servo-timed loading and positive case transport through the whole cell.
**6. Control and diagnostics.** A fault-diagnosis HMI that walks the operator to the exact sensor cuts mean-time-to-repair by hours. Insist on it in the specification.
**7. Washdown readiness.** For food and pharma, verify stainless options, IP ratings and sealed bearings. Retrofitting washdown later is expensive.
**8. Integration points.** Conveyor heights, signal handshakes and OPC UA connectivity must match your line. Ask for a layout drawing in your format before ordering.
**9. FAT scope.** A real FAT runs your product and blanks at your target speed. Buy only from vendors whose FAT is a test, not a demonstration.
Why engineers choose YanMao case packers
Every YanMao packer — robotic, drop, wrap-around or side-loading — is engineered against these nine criteria and validated at FAT on your product mix. If you would like a copy of our FAT test protocol, contact our engineering team.
