A new iPul pultrusion system processes various reinforcing fibers: basalt, carbon, aramid, and glass. Competence Day Pultrusion will be held at KraussMaffei factory in Munich on June 28, 2017, where they will present iPul pultrusion system.
Live demonstration, specialist presentations on the process, networking will take part under the motto “More speed for pultrusion”.
The distinctive feature of iPul pultrusion system is that the open resin bath where impregnation of the dry fibers must take place is omitted. The matrix material is injected directly and continuously into the injection chamber. This system allows the production speeds become higher and sales markets are wider. The injection points can be easily and individually set and adjusted specific to the product.
Following the injection chamber the impregnated fibers are pulled through a heated stationary die. The component is cured in several individually selectable heating zones to achieve the desired hardened state. Due to this fact, the pultrusion machines iPul are able to manufacture not only straight but also curved profiles in the radius pultrusion process with production speeds of more than 3 m/minute (to date the speeds are generally 0.5 to 1.5 m/minute).
Another advantage of the new system from KraussMaffei is the flexibility in processing diverse reinforcing and matrix materials. Fibers made from glass, carbon, basalt, or aramid are mainly used as reinforcement fibers. Matrix is usually epoxy or polyurethane resins. It is also possible to directly work in additives such as mineral fillers, pigments or flame retardants.
KraussMaffei presented their novelty at JEC World 2017 in Paris. Pultruded profiles are characterized by their high fiber volume content and thus a high strength with low weight, making them suitable for use in the construction and wind power industries. The company is sure the main consumers will be from the wind energy and construction industries.
