High-Precision PP Extrusion with ±0.05mm Tolerance Across 4 Strands
Product Introduction
Precision is the foundation of high-quality PP strapping production. This advanced extrusion system delivers exceptional dimensional accuracy through an integrally formed high-precision 1-out-4 flow-diverging die head, precise temperature control, and stable haul-off and tension management. The system maintains width and thickness tolerances within ±0.05mm across all four simultaneously produced PP strapping bands, ensuring outstanding uniformity and consistency for demanding applications.
Key Specifications
Core Precision: Single strand dimensional tolerance ≤ ±0.05mm
Key Component: Integrally formed high-precision flow-diverging die head
Supporting Systems: Precise temperature control (±1°C), stable haul-off and tension control
Result: Highly consistent specifications across all 4 strands

Frequently Asked Questions
How is the ±0.05mm precision guaranteed? What is the key?
Precision is achieved through three integrated systems: 1) Precise Die Head: Optimized runner design and high machining accuracy ensure uniform melt distribution to all four outlets; 2) Stable Plasticization: High-precision screw/barrel matching and stable temperature control provide homogeneous, stable melt; 3) Smooth Haul-Off: Servo-driven haul-off machine with minimal speed fluctuation prevents stretching variations from affecting dimensions.
Can this precision remain stable during long-term production? What factors affect it the most?
Yes, long-term stability is maintained through wear-resistant alloy steel construction and chrome-plated rollers that ensure durability of key components. The most significant external factors affecting precision are raw material consistency (pellet size, MFI stability) and cooling water temperature stability. We recommend using qualified raw materials and maintaining stable cooling system operation for optimal performance.
If I want to produce straps of different specifications, can I still guarantee this precision after changing the die?
Yes. Custom dies provided for different specifications utilize the same high-quality die steel and precision machining processes. When die changes and adjustments are performed according to our operating procedures, the new specifications will maintain the same high-precision standards. The quick-release flange connection system facilitates precise installation and changeover.
