Çift Katmanlı Yüksek Hızlı Makara PND315 - PN1250 | Kablo Üretimi için Güçlendirilmiş Yüksek Hızlı Çelik Makaralar

In modern wire and cable manufacturing, high-speed drawing, stranding, and bunching machines demand bobbins that combine exceptional rigidity, precision concentricity, and superior dynamic balance. The Double Layer High Speed Bobbin PND315 to PN1250 (also known as double-layer steel bobbin or reinforced high-speed cable reel) is engineered specifically for these demanding applications. Manufactured from high-grade Q235 carbon steel plate through precision stamping, welding, and machining, these bobbins feature a distinctive double-layer (reinforced double-wall) flange design that delivers outstanding strength, minimal vibration, and stable performance at linear speeds of 25 m/s to 50 m/s.

Ideal for both ferrous and non-ferrous wires, these high-speed process bobbins ensure uniform winding, reduced downtime, and consistent coil quality across cable, steel rope, and strand production lines.

1. Description & Primary Applications

PND315–PN1250 Double Layer High Speed Bobbins are purpose-built production reels for:

• High-speed drawing machines, stranding machines, and bunching equipment
• Manufacturing of power cables, communication cables, optical fiber cables, data cables, steel wire, steel rope, copper wire, aluminum wire, and welding wire
• Take-up and pay-off operations requiring high rotational speeds and heavy loads

The double-layer flange construction provides enhanced rigidity and impact resistance, making these bobbins the preferred choice for high-productivity cable factories seeking maximum speed and reliability.

2. Structural Design & Engineering

These bobbins are constructed with a robust pressed steel double-layer flange and barrel assembly:

• Double-layer reinforced flanges – Extra wall thickness and internal reinforcement for superior bending strength and deformation resistance
• Precision-machined hub and barrel – Ensures excellent concentricity and dynamic balance
• High-strength welded joints – Maintain structural integrity under high tension and high-speed rotation
• Smooth, precision-finished surfaces – Prevent wire damage and promote uniform layering

The double-layer design significantly improves stability compared to single-layer or standard steel bobbins, allowing safe operation at the highest production speeds.

3. Key Features & Benefits

• High-Speed Dynamic Balance – Precision forming and balancing tests ensure vibration-free performance at 25–50 m/s
• Exceptional Rigidity & Strength – Double-layer flange construction delivers high mechanical precision and long service life
• Lightweight yet Heavy-Duty – Optimal strength-to-weight ratio reduces machine load while supporting large coil capacities
• Superior Concentricity – Minimizes wire breaks and ensures consistent cable quality
