TATA Advanced Systems Limited has successfully rolled out the first #AirbusC295 military transport aircraft from its Final Assembly Line in Vadodara, Gujarat, marking a historic milestone in India’s #aerospace manufacturing journey under the Make in India initiative. This achievement comes ahead of schedule and represents the first time a private sector facility has produced a #militaryaircraft in India. The rollout of the first C-295 aircraft from the Vadodara plant is part of a ₹21,935 crore agreement signed in 2021 between India and #Airbus Defence and Space of Spain. Under this contract, 56 aircraft are to be delivered to the Indian Air Force, with 16 supplied in fly-away condition from Seville, Spain, and the remaining 40 manufactured and assembled in India by #TATAAdvancedSystemsLimited . Military training programs This programme is intended to replace the ageing Avro fleet of the IAF and significantly enhance India’s tactical airlift capability. It represents a major boost t...

Both Multi Jet Fusion (MJF) and Selective Laser Sintering (SLS) are powder-based 3D printing technologies ideal for functional prototypes and end-use parts — but they each have unique advantages: MJF (Multi Jet Fusion) 🔹Faster build speeds 🔹Smoother surface finish 🔹More consistent mechanical properties 🔹Excellent for detailed features and assemblies 🔹Suitable for higher volume production SLS (Selective Laser Sintering) 🔹Greater material flexibility 🔹More post-processing and finishing options 🔹High thermal and chemical resistance 🔹Well-suited for parts with complex geometries and internal channels 🔹Better for low volume batch prototyping Both are strong choices — but the right one depends on your design goals, part complexity, and performance needs. source : HLH Prototypes Co Ltd

𝗔 𝘀𝗺𝗮𝗿𝘁𝗲𝗿 𝗯𝗮𝗿𝗿𝗶𝗲𝗿 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝗳𝗼𝗿 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴 𝗱𝗲𝘀𝗶𝗴𝗻 Nichigo G-Polymer™ is a specialty vinyl alcohol resin developed for packaging designs that need both barrier performance and a more sustainable material approach. Its combination of water solubility, gas-barrier properties, and melt processability gives manufacturers more options in how they design and use barrier materials. 𝗡𝗶𝗰𝗵𝗶𝗴𝗼 𝗚-𝗣𝗼𝗹𝘆𝗺𝗲𝗿™ 𝘀𝘂𝗽𝗽𝗼𝗿𝘁𝘀: • 𝗕𝗮𝗿𝗿𝗶𝗲𝗿 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴 for dry food and other oxygen-sensitive products • 𝗕𝗶𝗼𝗱𝗲𝗴𝗿𝗮𝗱𝗮𝗯𝗹𝗲 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴 𝗱𝗲𝘀𝗶𝗴𝗻𝘀, including grades certified “OK compost” in the EU • 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗮𝗹 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 such as oil and gas, adhesives, binders, emulsifiers, and water-soluble core uses For manufacturers looking beyond conventional barrier materials, Nichigo G-Polymer™ is worth exploring for its combination of water solubility, barrier function, and biodegradable-grade options. source :...

Sigma Advanced Systems has signed a seven-year agreement valued nearly £300 million (around ₹3,800 crore) with Rolls-Royce to manufacture and supply a wide portfolio of high-precision-engineered, safety-critical components and assemblies for the latter’s aerospace programmes. The contract provides a long-term revenue stream and stronger visibility over future growth, Sigma said. It is a programme-level partnership delivered through its manufacturing network across India and the UK. The partnership builds on an existing relationship. With proximity, engineering collaboration, and programme alignment in the UK, the company cements its transition from a system player to a more integrated manufacturing partner capable of handling larger work packages, the company said. An aerospace and defence company with more than three decades of manufacturing experience, Sigma operates across India and the UK, with expansion under way in the U.S. The company works with global aerospace and defence OEMs...

And that is why not all carbon nanotubes deliver the same performance. Thanks to their unique one-layer structure, single wall carbon nanotubes are long and highly flexible, with a high aspect ratio and exceptional intrinsic mechanical and electrical properties. They are able to form a widespread, homogeneous, and stable 3D conductive network within materials at ultralow dosages. This makes it possible to create colorful or transparent conductive products with improved performance and durability.

  Great news. BASF and Sumitomo Chemical (through its license partner) have signed a license agreement that allows #BASF to use Sumitomo’s innovative HCl Oxidation globally.  At BASF Monomers, we operate production assets for #isocyanates in all key regions – US, Europe and Asia (China and Korea) and produce millions of tons of Isocyanates each year. One side product in this value chain is hydrochloric acid. With Sumitomo’s technology, BASF can now turn this #hydrochloricacid (HCl) back into Chlorine, which is then used again to produce Isocyanates in our plants. This important new process is part of our Verbund spirit and will make our isocyanates production even more productive and resilient in the future.  The agreement marks an important step in our partnership with #Sumitomo and our contracting partner #TechnipEnergies , and it reflects the trust and constructive spirit on all sides. A big thank-you to everyone who helped bring this together. We’re looking forwar...
