This was one of the earliest processes to be used in the plastics industry beginning with the forming of cellulose nitrate sheet in the mid 1800 s.

Amorphous plastics like abs and polycarbonate generally have wide processing windows and good melt strength making them easy to thermoform.
To do this large sheets of hips are heated and fitted over a custom tool.
Once heated hips is highly malleable meaning high impact polystyrene thermoforming is an excellent way to manufacture the plastics our customers need.
Some plastics like hdpe and pp have narrower processing windows and lower melt strength which make them more difficult but not impossible to thermoform.
Many plastic sheet materials can be shaped by thermoforming.
It is sheet temperature that dictates the process the end result being not just a better product but also decreased cycle time less scrap less floor space and reduced energy and labor costs.
High impact polystyrene thermoforming.
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 stretched into or onto a mold and cooled to a finished shape.
Styrene is commonly used in prototypes as it is dimensionally stable and easy to fabricate paint and glue.
Styrene is also nontoxic and odorless with excellent forming properties.
Styrene thermoform plastic sheets high impact styrene is an inexpensive thermoform plastic that is easy to work with and produces excellent vacuum forming results making styrene the perfect beginner plastic for folks who are new to vacuum forming.
Sheet temperature is one of the most critical elements of the thermoforming process.
Polystyrene plastic sheets for thermoforming hips sheets high impact polystyrene sheets products can be color matched to meet your specifications available textures smooth matte for more.
Thermoforming is an industrial process in which thermoplastic sheet or film is processed into a new shape using heat and pressure.
