Plastic Blow Molding

Blow molding is a highly developed molding technology, it is best suited for basically hollow parts (such as plastic bottles) with uniform wall thicknesses, where the outside shape is a major consideration. The blow molding are widely used in bottles, containers, liquid soap, shampoo, motor oil tank, drums, tubs, and storage tanks.

Plastic Blow Molding Products Samples

Blow molded parts can be formed from a variety of thermoplastic materials, including the following:
1. Low Density Polyethylene (LDPE)
2. High Density Polyethylene (HDPE)
3. Polyethylene Terephthalate (PET)
4. Polypropylene (PP)
5. Polyvinyl Chloride (PVC)

Our Capabilities:
Wall-Thickness: 0.1mm ~ 8.0mm
Product Size Range: 10mm ~ 1,500mm
Product Weight Range: 0.05kg ~ 50.00kg

Extrusion Bottle Blow Molding:
In extrusion blow molding, plastic is melted and extruded into a hollow tube. This parison is then captured by closing it into a cooled metal mold. Air is then blown into the parison, inflating it into the shape of the hollow bottle, container or part. After the plastic has cooled sufficiently, the mold is opened and the part is ejected. Continuous and Intermittent are two variations of Extrusion Blow Molding. In Continuous Extrusion Blow Molding the parison is extruded continuously and the individual parts are cut off by a suitable knife.
Examples of parts made by the extrusion bottle blow molding process include dairy containers, shampoo bottles, hoses/pipes, and hollow industrial parts such as drums.

Basic Process:
1. A thermoplastic resin is heated to a molten state.
2. It is then extruded through a die head to form a hollow tube called a parison.
3. The parison is dropped between two mold halves, which close around it.
4. The parison is inflated.
5. The plastic solidifies as it is cooled inside the mold.
6. The mold opens and the finished component is removed.
