Spring-Coil Filtration The surrounding coil spring retains ice fragments, fruit pulp and other solids during pouring. Spring tension and coil spacing are key quality-control points for maintaining consistent filtration across repeat production.
Fit and Stability Control The support points help keep the strainer positioned on the shaker or mixing vessel during pouring. Plate flatness, spring alignment and overall forming consistency are controlled to reduce rocking and fit variation between production batches.
