Blow Molding is an umbrella term for forming hollow plastic parts by inflating a viscous plastic tube, or parison, until it fills a mold and forms the desired shape. Think of it as inflating a balloon inside a water bottle.
Is Blow Molding the Right Choice?
Blow Molding is the fastest most cost-effective plastic molding process when production volume reaches 3,000+ parts per year. With an increasing focus on light weighting and sustainability, it’s no wonder why engineers across the globe in nearly every industry have turned an eye towards blow molding for their production needs.
Blow Molding vs Other Processes
Blow Molding can offer great benefits vs other processes. Those include, a faster production rate and tighter tolerances than Roto-Molding. Much more conducive to production of mid to higher volumes. Vastly improved design capabilities than thermoforming. Part shape, complexity, and size are rarely an issue. Far lower tooling costs than injection molding.
