What is blow Molding

We use extrusion blow molding (EBM) technology, where plastic is melted and extruded into a hollow tube (a parison). This parison is then captured by the mold. Air is then blown into the parison, inflating it into the shape of the hollow bottle, container, or part. The bottle is then trimmed, leak tested and packed out.
