Thermoforming is an extremely convenient process for forming plastic sheets both owing to its cost-effective nature and the impeccable results achieved. It is the ideal processing for products with a short life cycle, or linked to seasonability.
Thermoforming can be used to process ABS, PST, PETG, PMMA, PC, PETG, ASA and various other high-tech materials.
The sheet is heated to a certain temperature and then laid onto a mould for adhesion, thanks also to vacuum. The shape obtained is subsequently cooled, and introduced into dedicated containers for the subsequent 5-axis CAD CAM cutting phase.
The advantages, with respect, for instance, to injection moulding, lie in the possibility of using practically any type of plastic material, to obtain minimum thicknesses and also highly complex surfaces, with reliefs and grooves which would be impossible to achieve using any other method.
Compared with injection moulding, it also makes it possible to make small product runs, which are ideal for sectors such as fashion, lighting and medical rehabilitation.
Making components in plastic materials using thermoforming with respect, for instance, to using fibreglass or steel, makes it possible to reduce the weight and especially allows the combination of several elements in a single component, eliminating welds and signs of joining.
One of the fundamental advantages of Minini concerning thermoforming is that we are in a position to design and produce moulds in-house, which guarantees considerable cost cutting and shorter time frames, as well as the total secrecy of the design throughout the entire production cycle.
