Why Hydraulics Beneath the Mold Is the Preferred Choice?

Injection Blow Molding

Injection blow molding (IBM) is a widely used manufacturing process in the plastics industry to create hollow plastic products with precise dimensions and exceptional quality. One critical aspect of IBM machines is the choice between hydraulic systems placed beneath the mold and other alternatives. In this article, we will explore why hydraulics beneath the mold is the preferred choice and the benefits it offers.

As a leading supplier of injection blow molding machines and equipment, we, at Pet All Manufacturing, Inc., aim to provide valuable insights into the technology that drives our industry.

Understanding Injection Blow Molding

Injection blow molding (IBM) is a versatile technique that combines two stages: injection molding and blow molding. First, the plastic material is injected into a mold cavity to create a preform. Then, the preform is transferred to a blow mold, where it is inflated using compressed air to take the desired shape. IBM is commonly used to manufacture bottles, containers, and other hollow plastic products.

Hydraulics Beneath the Mold: The Preferred Choice

  • Enhanced Efficiency and Precision: Placing the hydraulic system beneath the mold offers better control over the molding process, ensuring precise and uniform pressure distribution. This results in consistent product quality and dimensional accuracy.
  • Reduced Energy Consumption: Hydraulic systems, when optimized and well-maintained, can be more energy-efficient compared to other alternatives. Lower energy consumption contributes to cost savings and aligns with sustainable manufacturing practices.
  • Ease of Maintenance: Hydraulics beneath the mold are accessible and easier to maintain, reducing downtime during routine checks and repairs. This enhances overall machine reliability and productivity.

Injection Blow Molding Machine Manufacturers

When it comes to choosing the right injection blow molding machine manufacturer, several factors should be considered:

  • Experience and Reputation: Look for manufacturers with a proven track record and positive customer reviews. Experience in the industry indicates expertise and reliability.
  • Technological Advancements: Consider manufacturers that offer the latest technology in injection blow molding machines. Advanced features can improve efficiency and product quality.
  • Customer Support and Training: Opt for manufacturers that provide excellent customer support and comprehensive training to ensure smooth machine operation and troubleshooting.

Plastic Molding Machine Selection

Selecting the right plastic molding machine is crucial for successful production. Here are some key factors to consider:

  • Machine Type: Determine whether an all-electric, hydraulic, or hybrid machine suits your production needs and budget.
  • Production Volume: Choose a machine with the appropriate clamping force and shot size to match your production requirements.
  • Quality and Reliability: Invest in a machine known for its durability, precision, and long-lasting performance.


In the world of Injection Blow Molding (IBM), choosing hydraulics beneath the mold proves to be the preferred choice for enhanced efficiency, precision, and energy savings. The benefits of this technology make it an ideal option for manufacturers looking to produce high-quality plastic products.
