Before power is applied

Confirm the machine matches the approved drawing and the order: frame dimensions, platen size, stroke, number of cavities, mould interface, heater zones and the voltage on the nameplate. Check that guards, interlocks and emergency stops are fitted as agreed, and that the electrical cabinet is wired to the schematic supplied.

No-load and sequence checks

Run each axis through its full stroke without material. On a cup machine this covers clamping, forming, cutting and ejecting; on a thermoformer it covers index, heating, forming, cutting and stacking. Watch for abnormal noise, air leaks, hydraulic seepage and any axis that hesitates at the end of its stroke. Confirm the safety circuit stops motion when a guard is opened.

Heater and temperature verification

Bring every heater zone up to set point and record the actual readings. Zone-to-zone deviation on the sheet line and the forming station should be reported as numbers, not as an impression. Ask for the record.

A timed production run

The machine should run the buyer's own material or an agreed equivalent for a continuous period, producing parts that are counted, weighed and inspected. Wall thickness, rim quality, stacking height and dimensional repeatability are measured on samples pulled from the run, not from the first few shots.

Documentation handed over

Manuals, electrical drawings, the spare parts list, the parameter record and the test report should leave with the machine. A machine that runs well but arrives without its parameter record is harder to restart after installation.

What to do with a finding

Record it, photograph it and agree the correction before shipment. Corrections made in Shantou cost days; the same corrections made on site cost weeks.
