Identifying the Root Causes of Uneven Wall Thickness:

Ensuring uniform wall thickness in IBC blow molding is an intricate process that demands a keen understanding of the various factors at play. By analyzing the following common factors that contribute to inconsistent wall thickness, manufacturers can begin to address the root causes and work towards achieving precise and consistent results.

1. Machine Settings:

The settings and parameters of the blow molding machine play a crucial role in determining the final wall thickness of the IBC tank. Variations in temperature, pressure, and blow time can lead to irregularities in the material distribution during the molding process. Identifying the optimal machine settings and calibration is fundamental to maintaining a uniform wall thickness throughout the production run.


2. Material Properties:

The characteristics of the raw materials used in the blow molding process significantly impact wall thickness uniformity. Variations in material viscosity, density, and melt flow index can result in uneven material distribution within the mold. Selecting high-quality and consistent materials is a critical step in achieving precision in IBC tank production.

3. Cooling Methods:

The cooling process is crucial in stabilizing the shape of the IBC tank after the extrusion blow molding phase. Inadequate cooling or uneven cooling rates can lead to warping and variations in wall thickness. Implementing efficient cooling methods and ensuring consistent cooling throughout the mold are essential to achieving uniform wall thickness.

Pinpointing Specific Challenges in the Extrusion Blow Molding Process:

Extrusion blow molding, while highly efficient, poses unique challenges that can affect wall thickness uniformity in IBC tanks.

1. Parison Control(GEFRAN,MOOG):

The parison, a hollow tube of molten plastic, is formed during the extrusion process and inflated to create the IBC tank. Inconsistent parison control can lead to variations in material distribution, resulting in uneven wall thickness. Tight control over the parison formation is essential to achieving precision in the blow molding process.


2. Wall Stretching:

During the inflation phase, the parison undergoes stretching, which can impact wall thickness uniformity. Uneven stretching or excessive stretching in specific areas of the tank can lead to thinning or thickening of the walls. Controlling wall stretching and ensuring uniform expansion of the parison are critical in achieving consistent wall thickness.
