This creative project was undertaken to determine the effectiveness and possible usefulness of a small, laboratory sized plastic blow molder. The design of this machine was similar to those units used in industry but fabricated on a much smaller scale.The blow molder was of the vertical extrusion type. It was actuated by a hydraulic cylinder, and the plastic was melted by means of electric heating bands.The extruded plastic parison was formed by two matching mold halves, and air introduced through a needle valve to expand the hot plastic to the shape of the mold cavity.
