Blow Molded Cases

Blow Molded Cases

Blow molded cases are formed by the process of blow molding, which is used to create uniform, hollow products. Blow molding uses a turned die head attached to a continuously running extruder, which forms a parison. The hot, hollow thermoplastic tube is set in the mold and held in place with clamps. Using a blow pin, air pressure is introduced through the inside of the parison, forcing it to assume the shape of the case mold. The case produced is then cooled by conduction or the evaporation of volatile fluids in the container.

Cases that are blow molded are durable, lightweight, recyclable and low cost. Blow molded cases can withstand freezing weather, they are not affected by moisture, oils, chemicals or solvents, and most can handle temperatures up to 180°F. Even rust, dents, splinters, cracks and scratches cannot affect plastic blow molded cases. The color is molded into the plastic, so it will not chip or peel off of the case.

There are many uses for blow molded cases. They can be used to ship, carry or protect sensitive materials such as electronics, computers, audio/visual equipment, monitors, laptop computers, hand held instruments and more. The durability and protective qualities of blow molded cases make them ideal for shipping delicate electronics or for use as electrical insulators. They are often used for storage because of their ability to withstand extremities. The lids and bases can be single or double walled, depending on the protection desired, and most cases have foam inserts, stock or custom made in order to fit and protect specific products or items.
