Operating conditions
Specify actual filling temperature, consistency and behaviour after standing. A trial at one temperature does not alone establish performance under different conditions.
Product path
Select hopper outlet, hose length and bore, pump or piston arrangement and nozzle opening together. Check stable supply at the required rate.
End of fill
Observe stringing and dripping at shutoff and during container changes. Container-mouth and surface cleanliness may form part of acceptance.
Cleaning & quantity checks
Define whether the target is in grams or millilitres. Plan drainage, changeover and cleaning access, then verify results with the actual product.
