Factory Acceptance Tests for a Plastic Crushing and Washing Line
Buyers should define pass or fail checks for a PP/PE film and woven bag recycling line before the factory acceptance test, covering throughput, washing, dewatering and drying.
A buyer specifying a plastic crushing and washing line for PP and PE film or PP woven bags should decide, before the factory acceptance test, which checks are pass or fail and which are only recorded. The reference throughput of 500 kg/h is a catalog value, not a promise for a supplied model, so the test should state the feedstock form, moisture and contamination used.
Ask the supplier to run the full sequence of crushing, washing, dewatering and drying on the agreed material. Useful pass or fail checks might include: does measured output over a timed run meet the agreed rate on the stated feedstock? Does the washed flake show visible residual contamination against a sample agreed in advance? Does the dewatered and dried output meet a moisture limit set in the contract? Are guards, interlocks and emergency stops functional?
Record conditions and results on a signed test sheet. Where a check is subjective, such as visual cleanliness, define the reference sample and who judges it.
Before requesting a quote, confirm with the supplier which feedstock the reference throughput applies to, how moisture and contamination will be measured, what test material they will supply, and whether the acceptance test is witnessed and documented.
