Infusion processing flow mesh range, technical composites expertise

Expo-Net Danmark A/S (Hjørring, Denmark) is promoting its extensive range of 100% recyclable extruded thermoplastic resin flow meshes. The flow mesh products developed and produced by the company are extensively used in composites manufacturing as essential vacuum infusion processing aids; during the new product development stage for large parts, such as for a wind generator blade or a yacht deck, up to four different custom-made resin flow mesh grades can be used in specific areas of an infused part to increase productivity and to avoid premature resin hardening and air voids. Expo-Net has been supplying wind blade producers for more than 25 years, and cites itself as a highly innovative, technically advanced, problem-solving partner. 

During 2023, Expo-Net continued to develop its technical knowledge, working closely with TechCollege (Aalborg, Denmark). A vocational education and training (VET) institute with more than 3,000 full-time students, one of TechCollege’s specialist offerings is a range of training courses on composite materials and processing. Testing of the 13 different resin flow mesh product grades supplied by Expo-Net was completed last year using the college’s facilities and support. The test program, instigated by Expo-Net to help customers better understand the rheological impact of different flow mesh grades and types, was developed and conducted by Mark Holmgaard Christensen, Expo-Net’s plant manager. Christensen is also a composite specialist development engineer and one of the examiners for the TechCollege composite training course.

Expo-Net has published the latest “Vacuum Infusion Resin Flow Mesh Technical Processing Guide 2024,” which provides comparative data on all Expo-Net flow mesh grades currently available. The guide enables an OEM or Tier 1 composite part producer to select the best flow mesh grades to use in different areas of a mold to consistently obtain the desired resin infusion speed and final part quality. Visitors to the Expo-Net booth stand will be able to hear about future developments, learn how Expo-Net can assist customers in more detail and obtain a copy of the updated technical processing guide.  

Expo-Net is a key supplier to a wide variety of customers and markets worldwide, supplying both directly and via approved supply chain distributors and kitting partners. The Expo-Net team provides a flexible, responsive customer service, customized products, technical support and a reliable supply chain delivery service.
