Aliancys is introducing Neomould 2017-S-1 resin for use in manufacturing composite tooling.
Composite moulds are used for cost-effective manufacturing of composite components in small to medium-sized production series (up to 500-1000 parts per year). They bring the designer the ability to create unique shapes, and composite tools also enable the manufacturing of large components like wind turbine blades, boats and façade panels for buildings. Compared to tools manufactured in steel, the production of composite tools is fast and versatile, Aliancys reports, and for these reasons composite moulds have built a track record of performance already over many years.
The zero-shrinkage feature of Neomould 2017-S-1 resin is said to enable the manufacture of parts that perfectly mirror plug surface and dimensions. At the same time the processing of the resin is fairly easy and robust, Aliancys says, and because of the thixotropic nature of the resin and high viscosity at low shear rates, it can be applied on vertical surfaces without sagging. Low viscosity at high shear rates makes the resin easy to apply in hand lay-up and spray-up processes and it is suitable for producing thick parts (up to 12 layers of glass in one go).
Aliancys has developed a Neomould tooling brochure guiding customers through the tool making process. Additional training and technical support are available through Aliancys technical experts.
“Our customers want to make composite components with unique shapes, taking advantage of the great design flexibility these materials offer,” comments Rob van de Laarschot, Head of Technical Service at Aliancys. “For them this means that the shape and surface quality of the mould must be perfectly aligned with the original plug. Aliancys can build on years of experience working with composite tooling materials, helping our customers to manufacture the perfect tool that can be used for making quality parts in consistent high volumes.”
