Extrusion blow molding can be operated as either a continuous or semicontinuous process depending on the requirement. In extrusion blow molding a plastic material feedstock is fed through a hopper onto a feeding transfer screw. This feeds material into an especially designed blow molding die that directs the material flow to create an extruded Practical Guide to Blow Moulding This process makes it possible to combine materials of various properties to create a final product to meet the requirements of a particular application. The first commercial application of this process was a Heinz Ketchup (tomato sauce) bottle by the American Can Company in 1983.

EXTRUSION BLOW MOLDING WITH FDM. EXTRUSION BLOW MOLDING PAGE 2 The FDM process is unique in its use of thermoplastics, and it is this feature that provides the benefi ts of rapid tooling for blow molding. Fortus PC can withstand both the temperature and pressure of blow molding (Figure 3). With no wear or deformation, an FDM tool can produce hundreds, even thousands, of molded parts in … Explaining the 3 Types of Blow Molding Techniques. The world of plastics is incredibly complex. There are so many different processes that go into creating plastic packaging, and one of the most popular methods of mass-producing plastic bottle containers is via blow molding.

Injection blow molding is the process of inflating a hot, hollow, thermoplastic preform or parison inside a closed mold, so its shape conforms to that of the mold cavity. Lomont Molding provides fully customized blow molding services for your project needs. Contact us, or request an in-depth quote today. Extrusion blow moulding is generally two type’s i.e 1) Continuous extrusion blow moulding & 2) Intermittent extrusion blow moulding. Continuous Extrusion Blow Molding. The parison is continuously extruded throughout the cycle. It can only be used with materials that have good melt strength. It also can only be used for short cycle times.
