Today's KNOWLEDGE Share ❄️Pressing laminated glass below the glass transition temperature (Tg) for the interlayer can produce glass that looks sealed, clean, and acceptable, yet carries hidden defects that only reveal themselves during autoclaving or months later in service. the proper transition temperature (Tg) • PVB > ~40 °C • SGP > ~55 °C 🔥Above Tg, polymer chains become soft and mobile, allowing the interlayer to flow and wet the glass surface fully. This mobility enables molecular bonding and hydrogen bonding to form between the interlayer and glass, creating a strong, durable adhesion essential for laminate integrity. ❄️Below Tg, polymer chains are rigid and stuck, so adhesion is weak or incomplete. ⚠️ When glass is pressed too cold, several hidden quality problems already exist, even if the glass looks acceptable. • Weak temporary adhesion, polymer chains can’t rearrange, so bonding is fragile. • Loss of transparent edge zone, normally a clear 15–20 mm edge indicat...

The way hundreds of tiny parts work together in perfect harmony – without batteries, just raw engineering excellence and pure precision. As I travel and meet with partners, I notice a pattern: many engineers and technical leaders still proudly wear mechanical watches. Why? Because they represent more than timekeeping. They are a symbol of respect for craftsmanship, the process, the discipline, and the beauty of precision. 💡👨‍🔧⌚ And honestly – it reminds me a lot of what we do in the injection molding industry. Especially at ENGEL. Whether it's an all-round machine built for versatility, or a lightning-fast e-motion or e-cap running with a 2-second cycle time 🏎️🔥 – it's all about custom-built solutions and tailore...

A new Bioeconomy Investment Group is being set up to help Europe’s sustainable industries secure the funding they need to grow. The group aims to reduce financial risks for investors, create clear funding standards, and bring together public and private money. Despite already supporting  17 million jobs  and generating up to  €2.7 trillion  in economic value, many innovative bio-based projects struggle to secure financing at critical stages, such as moving from small-scale testing to full industrial production. This funding gap risks holding back Europe’s ability to turn scientific breakthroughs in biotechnology and sustainable materials into real-world industries.   To fix this, the European Commission and the Circular Bio-based Europe Joint Undertaking (CBE JU) have brought together European banks, national promotional institutions, venture capital funds and institutional investors to create the  Bioeconomy Investment Deployment Group (BIDG).   ...
