Screw Packaging Machine
A high-speed vertical packaging system for screws, bolts, and fasteners (M2–M12, 3–60mm length). Combines vibratory bowl feeding, servo-driven dosing, and precision thermal sealing. Compatible with multi-layer films (PET/PE, OPP/LLDPE) and compliant with CE standards. Built for industrial durability with stainless steel components and PLC automation.

Procurement Guidelines
Performance Validation Protocol Key Notes
Tests focus on screw compatibility, jamming risks, laminate integrity, and COF compliance.
ASTM D1894 is used for COF measurement.
| Performance Validation Protocol | Parameters |
|---|---|
| Conduct ISO 2859-1 sampling tests with | Mixed-batch screws (varying head types: pan, flat, hex). Extreme aspect ratios (test 1:6 bolts for track jamming risks). |
| Verify film compatibility | Laminates: PET/AL/PE (80-150μm thickness, seal layer ≤50μm). Coefficient of friction (COF): ≤0.3 (ASTM D1894). |
Critical Component Specifications Key Notes
Vibratory Bowl: Baseplate uses corrosion-resistant stainless steel with a wear-resistant coating; leaf springs meet strict hardness and fatigue criteria.
Cutting System: Precision blade specifications ensure minimal wear and alignment accuracy validated via laser interferometry.
| Critical Component | Specifications |
|---|---|
| Vibratory Bowl | Baseplate: DIN 1.4301 stainless steel with micro-arc oxidation coating (≥15μm thickness). Leaf springs: SK7 spring steel (hardness HRC 45-50, fatigue life ≥5×10⁶ cycles). |
| Cutting System | Tungsten carbide blade (Grade K20, edge radius ≤5μm, surface finish Ra ≤0.2μm). Blade alignment tolerance: ±0.05mm (verify via laser interferometry). |
Preventive Maintenance Recommendations
Perform vibration analysis quarterly (5-10kHz spectrum, baseline comparison).
Conduct tribology testing on lubricants (kinematic viscosity change >10% requires flush).
Replace all O-rings annually (FKM material, hardness drop >10 Shore A).
Note: Service intervals based on 16hr/day operation with 60% duty cycle. Maintain MTBF >4,000hrs through scheduled component rotation.
