Blown Film Die Head

Since our blown film extrusion die head are delivered to your location in the assembled when they leave our factory, it is very convenient for your subsequent installation.

First of all, stop the operation of the blown film extrusion machine machine, connect the joint we give you with your screw, and then install the original air ring or the air ring purchased from our factory.

After checking the screw on the extrusion die head, adjust the thickness and width of the film everywhere to meet the requirements.

Finally turn on your blown film extrusion machine.

An extrusion die head is a crucial blown film extrusion machine parts in the extrusion process, used to shape materials, typically polymers, into continuous profiles like pipes, sheets, and films. Attached to the end of an extruder, it consists of a die body, mandrel (for hollow profiles), die lips, and flow channels. The material is forced through the die head, where it is shaped by the die lips into the desired form. Types of die heads include flat dies for sheets, annular dies for pipes, and profile dies for custom shapes. The design and quality of the die head are vital for ensuring uniform material flow, consistent dimensions, and high-quality surface finishes in the final product.

Flat Die Extruder: This type of extruder produces flat sheets or films, commonly used for packaging materials, insulation, and roofing materials.

Round Die Extruder: This extruder produces tubular or round profiles, such as pipes, tubes, and rods.

Multi-Manifold Die Extruder: This extruder can produce multiple profiles simultaneously, making it suitable for applications like window and door frames, siding, and fencing.

Coextrusion Die Extruder: This type combines multiple layers of different materials, creating products like barrier films, laminated materials, and multi-layer pipes.

Wire Coating Die Extruder: This extruder is designed to coat wires or cables with plastic insulation, used in applications like electrical wires, coaxial cables, and fiber optic cables.

When selecting an extrusion die head, buyers should prioritize compatibility with the specific plastic material being processed. Factors such as melt flow properties, temperature range, and viscosity are crucial to consider. Additionally, the desired size and shape of the final product should dictate the die head's design.

The extrusion process itself is another important consideration. Inline or crosshead dies may be more suitable depending on the project. The quality of the die head is paramount, as it directly affects product quality and minimizes downtime.

Extrusion output should align with production requirements. Buyers must also differentiate between solid and hollow extrusion processes, choosing the die head accordingly. Compatibility with existing equipment is essential; consider size, connections, and mounting options for seamless integration.

Maintenance ease is a vital factor. A die head extruder that's simple to disassemble and clean reduces downtime and optimizes production. Finally, cost-effectiveness is crucial; balance the budget with the die head's ability to meet production demands.

The cost of a blown film die head can vary significantly depending on several factors:

Size and Capacity: Larger die heads for higher production volumes will naturally cost more.

Material: The materials used in the die head construction, such as stainless steel or specialized alloys, will impact the price.

Complexity: Multi-layer die heads or those with complex internal channels for co-extrusion will be more expensive than simpler single-layer designs.

Customization: Customized features like specific lip shapes, cooling channels, or wear plates will increase the cost.

Manufacturer: The brand and reputation of the die head manufacturer will also influence the price.
