There are many different things involved with the manufacturing process. Thermoforming refers to a practice in which plastic sheets are heated up and made to be pliable. Then, they are formed to a specified shape using a mold, and finally trimmed to produce a usable good. There are many different purposes for this practice.
The sheet, also called film, is made from thinner gauges or other materials. These are heated to a temperature so high that it makes the sheets become pliable. This pliability is useful for when it comes time to stretch and mold the pieces into various forms and designs.
There are complex and simple ways to go about this. When done the simple way, a machine made for a lab or a small tabletop device can be employed to heat small areas of plastic. Then it will be stretched over a mold using a certain type of vacuum device. The technique is applied in many industries and is often used to create prototypes and sample parts.
There are also more complex and high-volume approaches to the process. In these situations, large production machines are used to heat and form the sheets and trim the formed parts from the sheet at a high speed. In the end, this produces thousands of finished goods per hour, but productivity might depend on the machine settings and mold size for the formed parts.
This process is different than blow, injection or rotational molding processes, as well as most other approaches to processing plastic goods. A person who does this process must have proper training to ensure they know how to perform the process correctly and efficiently. Often times, special machines are built and designed to handle most of the process and so there are just workers on-site for mediation purposes or to stand in during technical issues.
The forming practice might be used in a variety of industries. Most companies that do this work will recycle their waste, including old plastic and scrap. This might involve compressing scraps using a special machine or using a grinder that turns the scraps into flakes that can be used for other purposes.
The recycle stuff might then be placed for sale or re-used at the facilities. Often times it is added into new extruded sheets that will eventually be formed again. Many different tools are needed to complete this process and people who work in this field must be trained, although a lot of computerized machines are involved in the process. This is a major part of manufacturing a variety of goods that are needed for many purposes.
