FAQs on PET Blow Moulding Machines

Can PET be blow molded?

Yes, PET (Polyethylene Terephthalate) is one of the most common plastics used in blow molding. At CRU AIR + GAS, PET blow molding machines are specifically designed to transform PET preforms into bottles and containers through a precise stretch-blow process. PET is ideal due to its strength, clarity, and barrier properties, making it perfect for packaging beverages, food, and pharmaceuticals.

What is a PET blow molding machine?

A PET blow molding machine is used to manufacture plastic bottles and containers by inflating heated preforms into molds, shaping them into desired forms.​

What industries use PET blow molding machines?

Industries such as beverages, pharmaceuticals, food packaging, and chemicals utilize PET blow molding machines for producing various containers.​

What are the benefits of using PET blow molding machines?

Benefits include high production efficiency, consistent product quality, versatility in container shapes and sizes, and support for recyclable materials.

How do I choose the right PET blow molding machine?

Consider factors like production capacity, container sizes, automation level, energy efficiency, and compatibility with your specific application needs.​

What maintenance is required for PET blow molding machines?

Regular maintenance includes cleaning, inspecting components, replacing worn parts, and ensuring proper lubrication to maintain optimal performance.​

How much does blow molding cost?

The cost of blow molding depends on several factors including production volume, mold complexity, automation level, and machine capacity. For small to mid-scale production, costs might range from $0.05 to $0.30 per unit, while high-capacity systems can significantly reduce cost per bottle. CRU offers efficient PET blow molding solutions that help reduce long-term operational costs with energy-efficient and high-speed systems.

What temperature do you blow PET preforms?

PET preforms are typically heated to 85°C to 120°C (185°F to 248°F) before being stretch-blow molded into containers. The exact temperature depends on the machine settings, preform thickness, and bottle specifications. CRU AIR + GAS’s PET blow molders are equipped with precise heating systems to ensure consistent preform conditioning for high-quality bottle production.

What is the process of PET blow?

The PET blow molding process involves:

  1. Preform Heating: PET preforms are heated uniformly using infrared heaters.
  2. Stretching and Blowing: The heated preform is placed into a mold. A stretch rod elongates the preform while compressed air blows it into the mold’s shape.
  3. Cooling and Ejection: The formed bottle is cooled and then ejected from the mold. Cru’s PET blow molding machines are designed to automate this process, maximizing speed and precision across various bottle shapes and sizes.
