8 Fold 2 Layer Head for Precision Coextrusion
Enhance your extrusion blow molding performance with the advanced 8 fold 2 layer head—a compact yet powerful die head designed for multi-cavity, dual-layer bottle production. Engineered for precision, this extrusion head delivers consistent quality and output across all cavities, making it ideal for high-volume packaging applications.
Whether you’re producing layered bottles for food, pharmaceuticals, or industrial use, this coextrusion head offers excellent flexibility, durability, and control.
What Is an 8 Fold 2 Layer Head?
The 8 fold 2 layer head is a coextrusion die head featuring eight flow channels (or folds) with a dual-layer configuration. It allows two different materials—or the same material with different properties—to be coextruded in a structured format. This results in bottles with improved barrier performance, enhanced visual appeal, and customizable mechanical properties.
With its compact design, this head supports a minimum center distance of 80 mm and a maximum die size of 40 mm, making it an efficient solution for small to mid-size containers produced in multi-cavity molds.
Key Benefits of the 8 Fold 2 Layer Head
1. High-Efficiency Multi-Cavity Output
With eight individual flow folds, this head enables simultaneous production of multiple containers. The design ensures each cavity receives the same material flow rate and wall thickness, maintaining uniformity across all products.
This is particularly beneficial for high-speed lines that require consistency and reduced cycle times.
2. Dual-Layer Structure for Enhanced Performance
The two-layer coextrusion capability allows for:
-
Barrier layers to protect contents from oxygen, UV, or moisture
-
Cost savings by using regrind or recycled material as an inner layer
-
Enhanced aesthetics with colored outer layers or high-gloss finishes
The 8 fold 2 layer head allows processors to fine-tune the layer ratios and adapt to various product specifications and industry needs.
Optimized for Compact Mold Layouts
Minimum Center Distance: 80 mm
With a minimum cavity spacing of just 80 mm, this head is designed to fit efficiently into compact mold designs. This allows for more cavities in a smaller mold base, increasing output without increasing machine size.
Maximum Die Size: 40 mm
The head supports a maximum die size of 40 mm per cavity, ideal for producing small bottles, such as:
-
Cosmetic containers
-
Travel-size shampoo bottles
-
Sample packaging
-
Pharmaceutical containers
This makes the 8 fold 2 layer head an excellent choice for markets that demand high-volume, small-format packaging solutions.
