What's the advantage of Bulk Spiral Die-head

The Bulk Spiral Die-head offers several important advantages for industrial plastic pipe production, especially for large-diameter or high-strength applications. Here's a structured breakdown:

Key Advantages of a Bulk Spiral Die-head

1. High Output Capacity

Designed for large-scale production (e.g., >1000 kg/h).

Ideal for thick-walled or large-diameter pipes (e.g., 200mm–1600mm).

Supports continuous 24/7 operations with minimal downtime.

2. Uniform Wall Thickness

The spiral flow channel design distributes molten plastic evenly.

Prevents defects like weld lines, thin spots, or voids.

Critical for producing pressure-rated or load-bearing pipes (e.g., SN8, SN16).

3. Excellent Melt Homogenization

Ensures consistent temperature and viscosity across the entire cross-section.

Enhances pipe quality, structural integrity, and resistance to deformation.

4. Supports Multi-layer Pipe Structures

Can produce co-extruded pipes (e.g., outer corrugated + inner smooth layer).

Allows for material optimization (e.g., recycled outer layer + virgin inner layer).

Widely used in structured-wall and double-wall corrugated pipe systems.

5. Flexibility and Customization

Can be customized for different pipe designs, diameters, or wall profiles.

Compatible with a variety of thermoplastics: HDPE, PP, PVC-UH, CPVC, etc.

6. Reduced Material Waste

High precision flow control minimizes start-up scrap and material loss.

Efficient use of resins lowers production costs.

7. Durability and Easy Maintenance

Typically made of nitrided or stainless tool steel for wear resistance.

Engineered for easy cleaning, disassembly, and nozzle changeover.

8. Compliance-Ready

Often used in lines producing UL, ISO, or ASTM standard-compliant pipes.

Ensures reliable quality for municipal, telecom, and civil infrastructure markets.
