Today's KNOWLEDGE Share PEEK vs PAI: why do Europe, China, and the US make different choices? Across the globe, OEMs face the same question: how do you insulate ever-smaller, ever-hotter hairpin windings? But as evidence shows, the solutions they pick are not just shaped by raw performance. 🇪🇺 Europe leads the PEEK charge. Sustainability regulation is flipping the script. In 2025, the EU implemented the CAFE regulation, which sets a CO2 emissions limit of 93.6 grams per kilometre. Other significant regulations include EU Battery Regulation 2023/1542, which mandates design-for-recycling and carbon-footprint disclosure. As a result, solvent-free and re-meltable materials such as PEEK are quickly becoming the smarter choice for high-voltage insulation used by E-motor references like Schaeffer and ZF. 🇨🇳 China leans on enamel (for now). Main-stream 400V models keep costs low with traditional thermoset coatings. With average EV sticker prices running about half of Europe’s, it’...

  Today's KNOWLEDGE Share 🔹 Why Venting Is a Critical Detail in Mold Design In injection molding, venting may seem minor—but it plays a major role in part quality. When plastic fills the mold cavity, air needs to escape. If vents are missing or poorly placed, the trapped gas causes: ❌ Burn marks ❌ Incomplete filling (short shots) ❌ Weld lines ❌ Flashing or surface defects A good venting strategy ensures: ✅ Smooth flow without trapped air ✅ Better surface quality ✅ Lower injection pressure ✅ Longer mold life Our engineers evaluate vent locations as part of every DFM review—long before the mold is built. It’s just one of those behind-the-scenes decisions that leads to fewer defects and more consistent results. Design smart. Vent smarter. source : SCSPlastic

  Today's KNOWLEDGE Share 📢 Time to get technical... 📢 From A to S glass, and from mats to unidirectional rovings, every type and form of fiberglass has its own strengths (literally). But here’s the real question: ⚡ Which form wins on tensile strength? 📊 And how much does fiber volume fraction tip the scales? The combinations are endless...the performance differences are not. At The Native Lab, it’s not just about working with materials, it’s about knowing which material, in which form, delivers the right performance for the job 📖 Source: Composite Materials, Design and Applications book pg. 47 credits: The Native Lab

 🔧 Mechanical Design Fundamentals – Types of Stress In mechanical design, every component experiences forces. How these forces act determines the type of stress inside the material. A good designer must understand these before creating CAD/CAE models. 1️⃣ Stress (σ) 📌 Definition → Internal resistance offered by a material per unit area when an external force is applied. 📌 Formula → σ = F / A 📌 Units → N/m² (Pascal or MPa) ✔ Why it matters? Stress analysis ensures that parts don’t fail under real-world loads. 2️⃣ Tensile Stress (Tension) Occurs when forces try to stretch or pull apart a material. 👉 Example → A rope in a crane lifting a load, or a bolt under axial pulling force. ✔ Designers must ensure the ultimate tensile strength (UTS) of the material is higher than working stress. 3️⃣ Compressive Stress (Compression) When forces push or squeeze a material, reducing its length. 👉 Example → Columns, pistons, or press-fit joints. ⚠ Risk → Buckling (sudden sideways failure in lo...
