Why Choose Custom Blow Molding?

The benefits of blow molding, whether you choose extrusion blow molding, injection blow molding, or stretch blow molding, offer a number of benefits over other plastic manufacturing methods. Blow molding is:

  • Reasonably affordable
  • Faster cycle times
  • Well suited to the fabrication of hollow plastic parts
  • Ability to offer high volume production
  • Used for molding complex parts


How Do Our Blow Molding Machines Work?

Our highly specialized blow molding process allows us to offer a wide range of custom products across hundreds of different industries including automotive manufacturing, storage, transportation, healthcare and more. This process takes a few seconds per product, and our blow molding machines are capable of producing thousands of  units per hour.

Step 1 – Plastic is melted and made into a preform or parison using injection molding

Step 2 – The preform or parison is clamped into a mold, where the mold’s shape will determine the ultimate shape of the blow molded plastic.

Step 3 – Air pressure is introduced, causing the parison to swell and take the shape of the cavity.

Step 4 – The end product is cooled, either with water, conduction or evaporation.

Step 5 – After the plastic has cooled and hardened, the mold is released and the product ejected.


What Materials Can You Use in Blow Molding?

Thermoplastic resins are used in the blow molding process, including:

  • HDPE (High Density Polyethylene): Excellent impact and chemical resistance. Good cold temperature properties. Dimensionally not as stable as other materials.
  • PP (Polypropylene): Excellent chemical resistance. Rigid, with very good impact strength. Good at higher temperatures. But dimensionally not as stable as other materials, similar to HDPE.
  • PETG (Polyethylene Terephthalate Glycol): Clear, with excellent impact strength. Forms well.
  • PC (Polycarbonate): Very high impact strength. Clear. High temperature resistance.

Moving Beyond Plastics into a Sustainable Future

The plastic bottle was one of the first products to be fabricated when the blog molding machine was designed in 1939 and, within 60 years, the US was producing over ten billion plastic bottles for soft drinks every year. But as times have changed, and the pressure to create renewable, earth-friendly products has increased, manufacturers are shifting their focus to sustainable, recycled blow molding products.
