The Advantages of Using the Stretch Blow Molding Process

Stretch Blow Molding

In the world of molding, manufacturers rely on several different processes. One of these is stretch blow molding, which offers some unique advantages. Used by companies of all sizes and industries, the finished product from stretch blow molding has a direct impact on success. For this reason, it is imperative that you work with a reputable company that relies on the most advanced stretch blow molding machine and raw material available.

Out of the many different types of machines available, the best by far is a PET stretch blow molding machine. This machinery comes in both a single- and two-stage design.

  • A single-stage stretch blow molding machine makes it possible to product biaxial-oriented PET bottles. With incredible versatility, this machinery can produce a broad range of plastic bottles and jars in varying shapes and sizes.
  • The two-stage design has a much faster output rate compared to a single-stage machine. This process also increases cavitation by as much as 32 percent, thereby enhancing the quality of the bottle or jar neck. When designed with six blow molds, it can produce roughly 12,600 bottles per hour. Also, a two-stage machine can make both preforms and finished products.

As you look at the stretch blow molding process as a whole, you see even more advantages. At the top of the list is the fact this innovative molding method stretches plastic bottles, jars, and containers in both the hoop and axel direction. Known as biaxial stretching, this increases tolerable drop impact, tensile strength, barrier properties, top load, and clarity.

According to experts who rely on a PET stretch blow molding machine daily, the increased strength makes it possible for manufacturers to reduce the overall weight of the finished product by as much as 15 percent. That has a significant impact on the cost of production, as well as shipping.

Whether you need plastic bottles, jars, or containers for water, milk, juice, laundry detergent, shampoo, and conditioner, or something entirely different, both the single- and two-stage stage stretch blow molding machine is critical to your success. The goal is to purchase machinery from a trusted source, one with years of experience in these machines and that offers variety and affordability.
