Frequently Asked Question

What is EBM tooling?

EBM, or Extrusion Blow Molding, tooling consists of dies and mandrels designed specifically to transform a molten parison of plastic into a hollow shape using air pressure against a mold cavity. Unlike injection molding, EBM tools are optimized for managing the wall thickness and distribution of the parison while providing cooling channels to solidify the plastic quickly in the mold shape. The design focus is placed on the blow pin, the parison programming, and the cooling performance of the mold shells, which must efficiently dissipate heat from the extruded material. This tooling is typically used for high-volume manufacturing of containers and technical parts where the specific requirements for blow-ratio and material stretch are constant. Maintenance of EBM tooling requires specialized attention to the parting lines and the cooling efficiency of the mold sections. For a deeper explanation, see: EBM Tooling Fundamentals.
