Molded plastic, ejection types

The ram pushes the accumulated material through the die head to form the parison as a shot. This type of machine is obsolete however, there are machines of this type out in the industry still in use. The extruder or plasticizer is stationary and can continuously feed heated plastic into the accumulator. The extruder may be programmed to stop when the die is filled to a predetermined volume and then start again after the parison is extruded. The extruder speed is adjusted to fill the accumulator at the proper rate so the parison is extruded almost immediately after the blow mold has opened and the product ejected. Fig. 13.8 is a photo of an original product blow molding machine of this style of equipment. [Pg.267]
