What is an extruder die head used for?

Shape Formation: The die head's internal geometry (the shape of the die opening) dictates the final shape of the extruded product.  This could be anything from simple shapes like pipes and sheets to more complex profiles like window frames or medical tubing.

Material Distribution: The die head ensures even distribution of the molten plastic across the die opening, which is crucial for producing consistent and uniform products.

Flow Control: It controls the flow rate and direction of the molten plastic, influencing the thickness and dimensions of the extruded product.

Cooling Control: In some cases, the die head may incorporate cooling channels to help solidify the plastic as it exits, improving product quality and dimensional stability.

Essentially, the die head acts as the final shaping tool in the extrusion process, determining the final form and quality of the extruded product.
