Breyer
Breyer is a specialist in manufacturing high-quality and efficient extrusion lines for plastic processing. The group is currently working on gap impregnation technology to open up new markets for the company in the field of composites. The process allows the automated production of a vehicle bonnet, made of CFK integral construction in only 15 minutes. Sandwich building elements can be manufactured in one single step. Using a fibre composite design, the weight of the bonnet has been reduced by 60%. Its weight is about 5kg.
The machine concept is essentially built of six modules: a basic machine with mould carriers, a tool kit with both mould sets and the central part, an injection system, vacuum device, temperature control and handling system. The tool comprises a tool frame and two mould halves. The maximum clamping surface size is 1.2 x 1.7 m.
The tools’ surface topography has been optimised to allow direct painting of components. The sandwich construction structure supports connecting elements for mounting in order to avoid subsequent installations of additional elements on the formed part.
For the set-up of the machine no elaborate foundation is necessary, as it is used (for example) for presses. Both process and machine are designed for low pressures (<10 bar), hence the whole construction is less extensive than high pressure machines. This is also beneficial for the movement dynamics. Fast open-close movements can be carried out by saving energy with linear units.
For a fully automated production the machine is supplied with handling systems that can be integrated into the machine concept.
The current version of the machine is set up for form sizes up to max. 1.2 x 1.7 m. The group will exhibit in Hall 16, Stand 16C18.
