6 Straps with ≤±0.05mm Consistency – PP Strapping Line
Precision Production Excellence
In PP strapping production, dimensional accuracy directly affects downstream strapping machine performance and product appearance. This production line utilizes a high-precision 1-out-6 flow-diverging die, two 50cc metering pumps for pressure stabilization, and full-line closed-loop temperature and speed synchronization to strictly control width and thickness consistency across 6 strands within ±0.05mm. This precision level far exceeds industry standards, ensuring every meter of strapping has identical specifications and providing reliable quality assurance for high-end customers. Whether for automated packaging lines or export orders, it meets the most stringent requirements.

Frequently Asked Questions
Is ±0.05mm precision easy to maintain in daily production?
Yes. As long as the raw material is properly dried (≤0.1% moisture) and cooling water temperature is stable (10-25°C adjustable), the closed-loop control system automatically maintains precision. A spot check every 2 hours is sufficient.
Will precision be affected if the raw material batch changes?
There might be minor effects. You can fine-tune extrusion temperature or haul-off speed via the touch screen to restore precision. Our PLC supports recipe storage, allowing different parameter sets for different materials.
What instrument measures this precision?
A digital caliper (0.01mm accuracy) or laser diameter gauge is recommended. Random sampling on the production line for width and thickness measurement.
