What To Know Regarding Thermoforming

By Genevive B. Mata


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 is not be confused with injection molding, blow molding, rotational molding or any other process that is commonly used for making plastic goods. A person that handles this kind of work must be trained properly. This is essential, although there are special devices used to carry out these tasks. Nonetheless, workers are involved with the process and available to remedy any technical issues that could mess up the production.

The process is seen in many different types of industries. A lot of companies involved in this work recycle all waste, which includes scrap and old plastic. Sometimes this is done by compressing all scraps using a balling machine. Other times a grinder is used to turn the scraps into flakes that can be otherwise utilized.

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.
