Puller

A "puller" in extrusion refers to a specialized machine or equipment used in the extrusion process to pull or draw the extruded aluminum profile through the die. The puller plays a crucial role in controlling the speed and tension of the extruded aluminum as it emerges from the die, ensuring a smooth and uniform product with the desired dimensions and properties.

Usage of Puller in Aluminum Extrusion:

• Profile Drawing: The primary function of the puller is to draw or pull the extruded aluminum profile through the die at a controlled speed, giving the profile its final shape and dimensions.
• Tension Control: The puller applies tension to the extruded aluminum to ensure consistent and uniform pulling, preventing any deformation or distortions.
• Speed Control: The puller controls the speed of the extruded aluminum profile as it moves through the die, ensuring the correct extrusion rate for the desired product.
• Cooling Assistance: In some cases, the puller may be equipped with cooling systems to assist in the solidification and cooling of the extruded aluminum profile.

How Puller Works in Aluminum Extrusion:

• Extrusion Process: The aluminum billet is heated and forced through a die to create the desired profile shape.
• Emerging Profile: The extruded aluminum profile emerges from the die with a continuous length.
• Pulling Action: The puller grips the emerging profile and pulls it through the die at a controlled speed.
• Tension Adjustment: The puller applies tension to the profile to maintain a consistent pulling force, preventing any irregularities in the profile shape.
• Cooling (Optional): Depending on the specific extrusion process and material, the puller may have cooling systems to aid in the solidification and cooling of the aluminum profile.
• Cutting and Stacking: Once the profile has been pulled through the die, it is cut to the desired length and may be stacked or further processed as needed.
