In manufacturing, pushing a process beyond its optimal conditions may increase speed, but it can also create defects, variation and customer dissatisfaction. 🎯 Control the process. Control the parameters. Control the quality. 💡 Optimize the process, don't just accelerate it. source : Six Sigma Manufacturing #quality #qualityassurance #qualitycontrol #qualitymanagementsystem

Tg helps describe mechanical behavior, processing limits, and overall performance. This infographic presents several factors that can influence Tg, including molecular structure, intermolecular interactions, and others. These trends apply to many polymers, but some  systems may behave differently depending on their chemistry, morphology, and formulation. Tg provides valuable insight into how a polymer will respond, but it should always be considered within the context of the entire material system. source : Roberto YAÑEZ #glasstransition #Tg

Conductor screen 2. XLPE insulation 3. Insulation screen All applied in a single, continuous motion where no air, no seams and no second tries. Once the cable enters the nitrogen curing tube at around 400 °C, the XLPE begins to cross-link under heat and pressure, turning from plastic into a solid, permanent electrical shield. It’s the moment a cable stops being metal and polymer and becomes one structure. Think of it like building a perfect highway for electrons like we use to. The conductor is the highway itself, dense with speeding electrons. But up close, it’s not smooth. It’s made of twisted wires with tiny gaps and ridges between them (pitch of wires). Those microscopic valleys and the interstice...

A door trim panel may look like a single component, but every surface has a different purpose—and a different engineering requirement. Class-A → The customer's interface. Visible, touchable, and judged on appearance. Class-B → The functional structure. Hidden after assembly, but critical for strength, fit, and function. Class-C → The hidden framework. Internal geometry where DFM, draft, and manufacturability matter more than cosmetics. The right surface classification doesn't just define quality—it influences tooling cost, tolerances, polishing effort, inspection requirements, and overall part cost. Class-A is the promise to the customer. Class-B and Class-C are the promise to the build. 💬 Which surface class do you think is the most challenging to design correctly—Class-A, Class-B, or Cla...

You will have killed Kaizen.” — Taiichi Ohno» This powerful principle reminds us that quality problems should never be hidden—they should be exposed and solved. 🔍 When an operator stops the line because of a defect, the right response is not to blame or punish. Instead: 🔴 Stop — Prevent the defect from moving forward. 🔎 Identify — Understand what actually happened. 🧠 Analyze — Find the root cause. 🛠️ Improve — Implement corrective action. 🔄 Standardize — Prevent recurrence. A strong Lean culture creates an environment where employees feel safe to raise problems, stop processes, and suggest improvements. 🙌 Remember: “A line that stops because of a problem can improve. A line that never stops because people ar...
