Why do Manufacturers Choose Plastic Carrying Cases with Foam

Blow Molded Cases

What is blow molding, and why should you consider it for your next carrying case? This manufacturing process is used to create high volume, one-piece hollow objects. When finished, the process creates a uniform and thin-walled container that is strong and reliable. Besides being a strong option for creating carrying cases, it is also  the economical choice.

The clearest advantages of using custom carrying cases include:

• Machine and construction costs are low compared to other case types.
• Cases have a single-piece construction, so cases do not need to have their halves connected. Two-piece construction is typically weaker than a blow molded case.
• Blow molded cases can have water and airtight construction, which makes them highly desirable for traveling.

Plastic Carrying Cases with Foam

The blow molding process offers manufacturers more options for design when compared to injection molding. For instance, the thickness of the walls varies depending upon design needs. To create blow molded carrying cases, a plastic tube is heated, and then it is filled with air. The process creates something like a balloon, but it is called a parison. A mold is clamped around the parison, which traps the plastics within the mold. Air then continues to fill the parison to create the desired shape. The plastic is cooled, and then custom foam is inserted. This is one of the best ways to create plastic carrying cases with foam.
