Cannon at JEC Europe 2015: Processing technologies for composites and thermoforming

[image_0][image_1]Cannon says in the past 50 years it has generated a significant number of innovative technological solutions for the processing of urethanes and, more recently, of epoxy-based composites. Complete manufacturing lines for the production of a thermosetting or a thermoplastic composite part - from glass- or carbon-preformer to the finished part, including chemical dispensing unit and mixing head, moulds, mould carriers, handling and heating systems and controls - are available at Cannon, from a single, qualified source, says the company. Among other available technologies, the following will be highlighted:[image_2][image_3] Estrim, a complete moulding solution for the HP RTM process designed for the production of automotive, leisure and sport parts. On top of dedicated preformers, polymerisation presses and moulds, Cannon offers third generation of the E-System, high-pressure metering and mixing equipment that guarantees fast demoulding times, high metering accuracy for part-to-part repeatability and long-lasting performance of the mechanical parts in contact with aggressive chemicals. In addition to a standard high-pressure injection system in closed mould - now available for three different methods of injection - two methods for the distribution in open mould of the resin over the carbon fibre inserts have been developed, for an optimal distribution of the resin across the entire mould surface: Estrim LLD for a liquid laydown and Estrim SLD for a spray application, that allow to reduce the specific pressure in the polymerisation press, thus reducing the investment in clamping equipment. The new Cannon LN mixing head series, specifically engineered for HP RTM process, will be presented.A third-generation preformer for carbon-reinforced composites will also be illustrated. Its design has been optimised in the past 15 years obtaining an industrially-proven solution able to cope with the demanding cycle times dictated by the automotive industry parts. The layout includes a stack preparation station where the multiple-layer material is assembled automatically, followed by a high-efficiency heating unit and a customised forming unit; the three stations are linked by a fast transfer system, able to perform a sophisticated draping action avoiding the premature cooling of the material. Numerous units have been sold in several countries, says the company.A new generation of presses suitable to be used with different technologies (HP RTM, gap injection, compression moulding, etc.) and different reinforcements (carbon and glass fibres, non-woven PP, etc). They feature an innovative parallelism control system and can be built with platen sizes up to 4,200 mm x 3,500 mm and clamping forces up to 3,600 t. Bigger dimensions are available upon request.The industrialisation phase of the innovative Cresim (Carbon Recycling by Epoxy Special IMpregnation) project, aimed at the development of proper processing methods for the manufacture of CFRP parts using recycled carbon fibres. This Life+ EU-sponsored project addresses fully the waste reuse issue by demonstrating a new innovative manufacturing process, which will potentially reuse up to 100 % of the carbon fibre waste and scraps from different industrial sectors, transforming a costing environmental problem of today in an opportunity of greening the production processes and getting economic benefit for tomorrow, according to Cannon.The equipment for the wind-power industry, that is rewarding Cannon with growing volumes of business worldwide, thanks to the availability of dedicated low-pressure resin dispensers for the infusion of epoxy formulations in the largest blades, manufactured for off-shore and conventional wind turbines. The series of Cannon low-pressure DX machines includes a three-component model that allows for the flexible use of two different hardeners in order to obtain different reaction profiles in accordance with the size of the moulded part, a stringent request coming from the aeolic blade manufacturers that have already appreciated the first two-components models. A degassing unit for resin and a glue dispenser for the application of two-components adhesive completes the series of solutions for this important sector of the power industry.An innovative complete compression moulding line for LWRT (Light Weight Reinforced Thermoplastics) now available for the production of light automotive parts such as engine shields. The new, completely redesigned mixing head for co-injection of polyurethanes and glass fibre for the InterWet technology. Currently used for lightweight, wide structural elements demanded by the transportation industry, as well as by sanitary ware manufacturers or in the wind-power industry, this new interesting solution allows for the manufacture of glass-reinforced polyurethane parts able to replace - with much faster production cycles - similar manufacturing methods based on low-pressure RTM injection. A new design of the mixing chamber significantly improves its efficiency in terms of glass fibre wetting and in-mould distribution. A completely redesigned chopping unit allows for higher glass fibre output and longer runs between the replacement of the chopper's blades. According to Cannon, all the above mentioned turn-key solutions are today available for composite parts manufacturers based across the five continents. Cannon says its network of direct offices and agencies guarantees prompt local service, availability of spare parts, technical and marketing assistance.
