Thermoforming technology

High production rates can be achieved using thermoforming technology. However, it is difficult to form high quality continuous fiber reinforced thermoplastic parts with demanding geometries, due to the restricted movement of the fiber.

Another route to protect polymers from oxygen, light and UV is to encapsulate the part with a continuous film of another, more-resistant polymer to provide a barrier to oxygen. This technology is also used for decoration of plastic parts (in mould decoration or IMD, painting, multilayer sheets for thermoforming. ..). There is no protection against heat. 

An overview is presented of TrexeTs MuCell microcellular foam extrasion technology and a description is given of its application to the manufacture of thermoformable PP sheet. The results of pilot scale thermoforming trials carried ont to optimise forming conditions and obtain data abont potential cycle time effects, measurements of the densities, flexnral modnlns and wall thicknesses of the sheets and containers made from the sheets and cell stmcture analysis are presented and discussed.

In this case the biopolymers are directly plasticized by thermomechanical means, and transformed through the classical forming technologies of the plastic industry injection-moulding, extrusion and thermoforming. These agromaterials keep a natural aspect, they are sensitive to the atmospheric conditions like wood, but they have no shape restrictions (Figure 5.20). 

Leading the processing growth was the expansion of twin-sheet and pressure-formed plastic products. Fueled mostly by advances in mold technology, material developments, and thermoforming machinery capabilities, technology improvements in the form of machine controls have led to machine designs that are faster and more consistent than was previously possible. As an example advanced materials and...
