Q: Why are Production Speed (BPM), 3D Container Drawings, and Label Specs mandatory for a Sleeve Labeling Machine quote?

1. Production Speed (BPM - Bottles Per Minute)
- Machine Architecture & Cost: Sleeve labelers range from single-head (economical, lower speed) to dual-head or tripple-head (high speed). The target BPM determines the mechanical structure, servo motor power, feeding mechanism, and overall line synchronization.
- Prevents Bottlenecks: Specifying the exact BPM prevents under-specifying (creating line bottlenecks) or over-specifying (wasting capital expenditure).
2. Container 3D Drawings & Precise Dimensions
- Mandrel & Cutter Design: The sleeve labeler's cutter assembly and central mandrel must precisely match the container's cross-sectional shape (round, square, oval, or tapered). Without 3D CAD files or physical samples, engineers cannot design the proper feeding screw to spacing containers; mandrel to open and position the sleeve correctly.
- Handling & Stability: Container material, surface friction, and geometry (grooves, handles) dictate the design of timing screws and starwheels to prevent tipping, jamming, or mislabeling.
3. Label Specifications (Material, Thickness, Flat Lay Width & Cut Length)
- Material Shrinkage Properties: Shrink sleeve materials (PVC, PETG, OPS, POF) have different transverse and longitudinal shrink ratios and tension behaviors.
- Cutting & Feeding Accuracy: Label thickness (typically 35μm to 50μm) and lay-flat width affect feeding friction, cutter life, and sleeving precision. A few millimeters of error can lead to loose sleeves or tearing during application.
