Resin feeder providing high and constant flow rates

Thanks to a wealth of advantages over alternative technologies, vacuum infusion and resin transfer molding still are becoming increasingly popular among composite part makers around the globe. They optimize resin usage and shorten production cycles, and that while safeguarding consistently high quality of the finished product. Examples of industries relying on vacuum infusion and resin transfer molding include the marine, sporting goods, and wind-blade industry. In all of these, EnkaChannel has already been successfully applied as a flow medium or feeder. The product provides an open channel with a superior flow capacity for the resin to travel freely. EnkaChannel is compatible with all resin recipes.

This is EnkaChannel

EnkaChannel-resin feed for vacuum infusion_copyrights Low & Bonar-Enka Solutions (2)EnkaChannel consists of a three-dimensional spacer matting wrapped in a thermally bonded nonwoven sleeve. The spacer is produced from polymeric monofilaments. These are pre-formed into a compression-resistant, yet flexible zig-zag configuration.

To accommodate different process settings and composite-part designs, EnkaChannel is available in two different widths. Both product variants come on 100 meter long rolls. EnkaChannel is easy to cut to size and fix in any mold.

How EnkaChannel is used in vacuum infusion

No matter how different the industries in which vacuum infusion is applied to produce composite parts, the basic principle is always the same: Rather than applying resin by hand, infusion uses vacuum pressure to drive resin into a laminate. A vacuum pump pulls the resin into the system by way of vacuum lines and a flow medium in the mold. The feed lines are connected to EnkaChannel, which acts as a feeder facilitating fast and regular resin transport into the composite part. Thanks to its high constant flow rates exceeding that of tubes and hoses, the product makes processing more efficient and helps reduce infusion time. At the same time, EnkaChannel’s unique configuration enables resin flow in x, y and z direction. And with EnkaChannel the imprints known from spiral wraps are also a thing of the past.

EnkaChannel is often applied in combination with an EnkaFusion resin transfer media.
