Hard Cases
Hard cases are heavy-duty protective containers made of rigid material for transit and shipping applications. They are crush-proof, usually waterproof, and can be flame resistant, static free and humidity-regulated. The automotive, athletics, business, outdoor, travel, medical, emergency, optical and music industries use hard cases to protect or organize items like camping equipment, first aid supplies, hearing aids, electronics, music production equipment, musical instruments and firearms. Many come with handles and wheels for easier transportation and protect valuable items from temperatures, dust, rain, and rough handling during travel or shipping. Many are made with foam insulation or fit snugly to the item they are protecting, and come in many different sizes and colors, including transparent.
Protective cases are made from different hard materials, including aluminum, fiberglass-laminated plastic or rubberized chromium. Plastics like polycarbonate or polyethylene are shatter-resistant and made of hard resin shells that are injection molded. These are often used to protect electronics like cell phones and MP3 players but still allow them to be used. They usually take the shape of the specific electronic by snapping together. They also often have holes for the buttons. Aluminum cases used for transporting expensive electronic equipment are often made of plaster and plywood that is riveted to an aluminum framework. For added protection from ware and tare, zinc-plated steel corners are nailed on the case exteriors.
