Finnish composites manufacturer Exel Composites, which specialises in pultrusion and pull-winding technologies, officially inaugurated its new aerospace production area at its Joensuu plant on 30 September 2026. Developed for the LCA60T programme of French-Canadian aeronautical company Flying Whales, the facility will support process validation and subsequently the production of the pull-wound carbon fibre tubes forming the structural frame of the airship. The LCA60T is a 200-metre-long vertical take-off and landing airship designed to carry payloads of up to 60 tonnes, particularly to and from areas with limited transport infrastructure. “There are approximately 80 kilometres of carbon fibre tubes inside one airship,” explains Paul Sohlberg, CEO and President of Exel Composites. “They form a beam structure inside the envelope that gives the airship its shape and provides the rigidity and structural performance it requires. The carbon fibre tubes therefore form part of the aircraft’s p...

They may look like small dents or depressions, but they reveal important information about how the part was filled and cooled. 🔍 Why do sink marks occur? Sink marks typically form when: 🧊 Local cooling is slower in thick sections 🌀 Insufficient packing pressure during injection 🧱 Ribs or bosses are too thick 🧩 Material shrinks unevenly during solidification Even a 0.5 mm geometry difference can create visible sinks — especially on glossy surfaces. 💡 𝐇𝐨𝐰 𝐭𝐨 𝐩𝐫𝐞𝐯𝐞𝐧𝐭 𝐬𝐢𝐧𝐤 𝐦𝐚𝐫𝐤𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐬 𝐜𝐚𝐧 𝐫𝐞𝐝𝐮𝐜𝐞 𝐬𝐢𝐧𝐤 𝐦𝐚𝐫𝐤𝐬 𝐛𝐲: 📐 𝐃𝐞𝐬𝐢𝐠𝐧𝐢𝐧𝐠 𝐫𝐢𝐛𝐬 𝐚𝐭 𝟒𝟎–𝟔𝟎% 𝐨𝐟 𝐰𝐚𝐥𝐥 𝐭𝐡𝐢𝐜𝐤𝐧𝐞𝐬...

LG Chem announced that it had recently signed a memorandum of understanding (MOU) at the LG Twin Towers in Yeouido to “develop and expand the application of next-generation, eco-friendly mobility materials. The signing ceremony was attended by executives from both companies, including Stefan Gramse, Executive Vice President and Head of the Exterior Materials Procurement Group at the #VolkswagenGroup , and Kim Sangmin, Senior Vice President and Head of LG Chem’s Petrochemicals Company.   Under this agreement, the two companies will collaborate on developing next-generation plastics and composite materials, as well as on reducing vehicle weight and improving performance, using LG Chem’s ABS (high-value-added synthetic resin) and EP (engineering plastics). ABS and EP are high-performance plastics with excellent impact strength, durability, and processability, and are widely used primarily in the exterior components of home appliances and in automotive interior and exterior parts. ...
