Dow a global materials science company, and RDM Group, a leading producer of recycled cartonboard, today announced the launch of Multiboard CirculaRR, a breakthrough solution that advances circularity in food barrier packaging. The innovation is suitable for food-contact applications, including frozen foods such as fish and cakes as well as fruit trays or dry pet food. Multiboard CirculaRR brings together RDM Group’s expertise in fibre‑based packaging with Dow’s leadership in circular polymers and advanced recycling technologies. The solution is made entirely with recycled materials – recycled paper coated with advanced recycled polyethylene (PE) – while maintaining the functionality performance required for demanding packaging applications. Building on proven materials, designed with end-of-life in mind The new solution builds on RDM Group’s existing Multiboard Barrier product, manufactured at the company’s facility in Fiskeby, Sweden. Multiboard Barrier is a recycled cartonboard coat...

Mitsubishi Chemical Corporation hereby announces that its #thermoplasticelastomers designed for medical applications, #Zelas™TPS , have been adopted for the cell culture tubes of the iP-TEC® series, a cell culture and transportation solution for regenerative medicine developed by #SANPLATECCORPORATION .

Here’s the TL;DR version of how it works: 1️⃣ Clean it up: Mold prepped & slick with release agent. 2️⃣ Gel coat time: Think smooth finishes & colored vibes. 3️⃣ Layer by layer: Resin + fiber + elbow grease = structure. 4️⃣ Curing mode: Let it set and get solid. 5️⃣ Pop it out: Trim, tweak, and boom ...it’s a part. Great for big & bulky parts, budget-friendly tooling and quick design tweaks. Perfect for prototypes or limited runs. Whether you're in marine, automotive, or just geek out on processes hand lay-up shows that sometimes the manual way still gets the job done ri...

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...
