3DX & SDC Systems

Dynamic Deformable Die 3DX system allow to change dynamically during the extrusion process the parison wall thickness distribution radially. The flexible 3DX ring is pushed and stretched by hydraulic pistons or servo electric actuators controlled by programmer profile and synchronized with the linear wall thickness piston of the machine allowing a perfect optimization of the final product’s thickness.

Static Deformable Core SDC replace the solid pin, the external flexible ring allow to be deformed in different areas depending on container final shape, this can be of great help to 3DX System in extrusion process.

How it Works

The mechanized matrix, or core, is one of the techniques that blow-moulding fabricators have used for years to improve the distribution of material, but the profile only modifies a part of the longitudinal area of the container. Often, what is needed is a die gap that changes shape as the parison extrudes. This is exactly what our 3DX system does. The flexible die, made from a special alloy, is controlled by two hydraulic cylinders.

5 Reasons to Use 3DX & SDC in the Processing of Blow-Mold Extrusions

  1. It saves resin
    This system allows the removal of the material from areas of the blow-molded part where it is not needed. On some parts, it can represent more than 10% savings on resins.
  2. Faster cycle times
    The areas with greater thickness need more time to cool. Eliminating these thicker areas allows for a faster cooling time.
  3. Parts with improved mechanical properties
    The areas with greater thickness on the blow-molded part are the main causes of failure during impact tests.
  4. Reduction in Deformations
    The areas with greater thickness on the blow-molded part cool slower than the thinner walls, this causes deformations in the blow-molded part.
  5. More competitive Products
    By reducing thickness in the thicker areas, we can lower the product weight and improve the mechanical properties with higher impact resistant and less weight. This allows us to go to the market with a more competitive product.
