Plastic Blow Molding
Blow molding and injection molding are two essential processes in plastics manufacturing; they are complementary rather than competitive.
The products resulting from these processes are used in a wide variety of industries: automotive, food packaging, electronics, medical devices, dental care, energy, and the environment.
Our brand-new cleanroom blow-molding unit allows us to manufacture hollow plastic parts, particularly containers (bottles, jugs) with capacities ranging from 100 ml to 5,000 ml—capacities that would be impossible to achieve using injection molding. The entire process is automated, from production to packaging. Whatever your project, the Sagaert Group has the solution.
Our expertise in plastic blow molding
A high-performance blow-molding unit
Our company is taking things to the next level with a brand-new cleanroom blow-molding unit. This high-performance machine allows us to manufacture hollow plastic parts, particularly containers (bottles, jugs) with volumes ranging from 100 ml to 5,000 ml—something that would be impossible with conventional injection molding.
The blow-molding process is fully automated, from production to packaging, ensuring rapid processing and consistent quality. Our process guarantees high resistance to deformation.
Blow molding involves blowing air (or compressed gas) into a tube of thermoplastic material, called a parison, that has been preheated to a high temperature. The tube passes through a nozzle and is then injected into a blow mold: the pressurized air pushes it against the mold to give it its final shape as a hollow object.
The most common example of this technique is still glassblowing, although our expertise focuses on polymer materials. We manufacture your bottles using the stretch-blow molding process.
Customized solutions for your projects
Whatever your project, our company provides you with a tailored technical solution. We manufacture custom vials, bottles, and containers—for food packaging, medical devices, and energy applications (fuel cells and electrolyzers). Our expertise and selection of materials allow us to incorporate specific features right from the design stage.
Blow molding offers great flexibility in terms of the product’s shape, volume, and color. We manage your project from start to finish: our engineering department works with you to design the ideal plastic part; we then manufacture custommolds; and finally, we launch mass production, which is monitored using our own quality control tools.

Plastic Blow Molding: Frequently Asked Questions
What is the difference between blow molding and injection molding?
Injection molding fills a closed mold with molten plastic to produce a solid part, while blow molding inflates a tube of material (the parison) against the walls of a mold to produce a hollow part—such as a bottle, can, or technical component.
What sizes of containers can you blow-mold?
Our blow-molding unit can produce volumes ranging from 100 ml to 5,000 ml—dimensions that would be impossible to achieve with conventional injection molding.
Do you work in a cleanroom for blow molding?
Yes, our new blow-molding unit is installed in a cleanroom, making it compatible with the requirements of the medical and pharmaceutical industries.
Can you manufacture custom bottles and caps?
Yes, we manufacture stretch-blow-molded bottles as well as caps and lids, offering a wide range of options in terms of shape, volume, and color.
Do you also make the mold for my blow-molding project?
Yes, our engineering department works with you to design the part, and then we manufacture customtooling before launching mass production, which is monitored using our own inspection tools.
For which industries do you offer plastic blow molding?
The automotive industry, food packaging, electronics, medical devices, dental care, as well as energy and the environment—particularly for components such as our fuel cells and electrolyzers.
