Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be ...
A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

I recently came across Twin Sheet Thermoforming as a type of thermoforming. Can we add a section for Types of Thermoforming similar to the Molding (Process) page. There is currently no Twin Sheet Thermoforming Wiki page to describe it. Eracer55 13:26, 29 March 2023 (UTC)
A simple visualization of the forming process Vacuum forming machine to produce inner liner/food liner of refrigerator. Vacuum forming is a simplified version of thermoforming, where a sheet of plastic in various forms of High Impact Polystyrene Sheet (HIPS) for low impact products, or ABS for bathroom shower trays, and HDPE for exterior vehicle parts, plus various other types of vacuum ...
A twin screw extruder or a continuous mixer may be employed to achieve a continuous stream, or a Banbury compounder may be employed for batch production. A higher degree of mixing and dispersion is achieved in the batch process, but the superheat batch must immediately be processed through an extruder to be pelletized into a transportable ...
In this state the material becomes soft so processes that are usually used on plastics can be applied, such as: thermoforming, blow forming, and vacuum forming. [1] Inert gas pressure is applied on the superplastic sheet forcing it into a female die.
Microthermoforming is the abbreviation for microscopic or microscale thermoforming, or, more precisely, for thermoforming of microproducts or microstructure products. Microstructure products means products that have structures in the micrometre range and have their technical function provided by the shape of the microstructure [1].
