Injection Molded Cases

Injection molded cases are durable carrying cases made of plastic that are used to hold and transport delicate or valuable pieces of equipment and protect them from damage. An injection molded case is created by a manufacturing process known as injection blow molding. Injection blow molding is performed in a specialized plastic manufacturing facility using advanced equipment to shape the materials into the dimensions of the case.

The plastic material that will be used for the case (usually polyethylene) is first melted down and then injected onto a core pin. As this core pin rotates over a molding station the material is inflated with air so that a hollow area is created in the middle. The plastic is then given time to cool. Once it has cooled down, the plastic is removed from the mold and it remains formed to the exact shape of the case mold. The same mold can be used over and over again to create a case with the exact same specifications.

Injection molding is an ideal manufacturing process for large volume runs in a major manufacturing facility where hundreds or even thousands of injection molded cases may be manufactured at the same time. This is because once the mold has been designed and the equipment has been programmed, the injection molding process itself is very quick and easy to repeat.

Injection molded cases are made in many different shapes and sizes depending on the types of objects that they are made to hold. They may be used for electronic devices, sound equipment, heavy tools, instruments or a wide array of other goods that a person would want to protect from damage. Most cases are built with clasps to keep them tightly sealed, and some even have a built-in key lock beside the carrying handle for added security.

If the case is designed to accommodate a very specific item, the mold may be setup in such a way that the hollow portion on the inside of the case is in the exact shape of that item. This way, when the item is placed inside it will not shift when the case is moved. Sometimes an inner foam lining is cut in the shape of the object and added to the case after it has been molded.

A high quality injection molded case has many advantages besides basic damage protection. These cases are waterproof, lightweight, immune to rust, impact resistant and scratch resistant. Specialized trades personnel can use these cases to carry their equipment without having to worry about it being damaged by an accident on a busy job site.

Injection molded cases are used in applications that range from military to engineering to healthcare and beyond. The durability of their structure and the infinite design possibilities that the molding process allows for makes them a great choice for almost any industry. A rugged design, cost-efficient means of production and high degree of customization make injection molded cases a highly sought after product around the world.
