Refrigerator Liners

The interiors of refrigerators are an important aspect of these appliances, as they help to keep food fresh and organized. These interiors are often made using a process called thermoforming, which involves heating a sheet of plastic and then shaping it over a mold to create the desired shape. One of the materials commonly used to make refrigerator interiors is polystyrene (PS), a lightweight and durable thermoplastic.

To make refrigerator interiors using thermoforming, the first step is to design and create the mold that will be used to shape the PS plastic. This mold is typically made from a material such as metal or fiberglass and is designed to match the exact dimensions and contours of the refrigerator being made.

Once the mold has been created, the PS plastic is heated until it becomes pliable. The heated plastic sheet is then placed over the mold and pressure is applied to push it down and conform it to the shape of the mold. The plastic is held in place until it cools and hardens, at which point it is removed from the mold and any excess material is trimmed away.

The finished refrigerator interior is then inspected for defects and any necessary finishing touches are applied, such as painting or adding hardware. These interiors can be made in various colors and finishes to match the aesthetic of the refrigerator or to add a touch of personalization.

The thermoforming process allows for the production of refrigerator interiors in large quantities and at a relatively low cost. Using PS plastic helps to ensure that the interiors will be lightweight and durable, which is important in a appliance that may be subjected to heavy use and harsh conditions.

Overall, the thermoforming process is an effective way to create refrigerator interiors using polystyrene material. These interiors help to keep food fresh and organized and are an important aspect of these appliances.
