New digital platform makes recyclability assessment faster and more reliable, to help companies prepare for packaging regulation. The Association of Plastic Recyclers (APR) today announced the launch of the APR Design® Assessment Tool powered by Recyda, a new digital platform that helps companies quickly and accurately assess the technical recyclability of plastic packaging and packaging portfolios. Early access is now available exclusively to APR members, with public availability expected in late September.  Built on the APR Design® Guide for Plastics Recyclability— the gold standard for designing plastic packaging compatible with the North American recycling system for over three decades—the APR Design® Assessment Tool was developed in partnership with Recyda, a leading provider of sustainable packaging software solutions. By combining APR’s technical expertise with advanced digital capabilities, the tool automates the design evaluation of complete plastic packages, helping compa...

In injection molding, that’s usually not the best approach. Instead, engineers often use ribs to increase stiffness while keeping the wall thickness uniform. 🔍 Why use ribs? Properly designed ribs can: ✅ Increase stiffness and strength ✅ Reduce material consumption ✅ Maintain lightweight designs ✅ Improve dimensional stability It’s one of the most efficient ways to reinforce a plastic part. ⚠️ Common rib design mistakes Poor rib design often leads to: ❌ Sink marks on cosmetic surfaces ❌ Uneven shrinkage ❌ Warpage ❌ Difficult mold filling More material doesn’t always mean a stronger part. 💡 Good rib design guidelines 📐 Rib thicknes...

Sunday's THOUGHTFUL Post ⚠️ “HUMAN ERROR” IS NOT A ROOT CAUSE An operator made a mistake. ❌ Investigation: “Human error. Retrain the operator.” 🔄 Problem solved? Not necessarily. If the same mistake can happen again, the root cause may still be in the system. 🔍 LOOK BEYOND THE OPERATOR Ask: 📋 Is the SOP unclear? 🖥️ Is the UX confusing? 🔄 Is the workflow too complicated? 🔢 Are there too many steps? 🚫 Is there no feedback or error-proofing? ⚙️ Is the process design flawed? 🧠 THE REAL QUESTION Don't ask: ❌ “Why did the operator make the mistake?” Ask: ✅ “Why did our system allow the mistake to happen?” 🛠️ BETTER ROOT-CAUSE THINKING Human Error → System Investigation → Root Cause → Corrective Action → Error-Proofing → Prevention 🎯 Training can be part of the solution. But retraining alone is often a band-aid, not a systemic corrective action. 💡 Design the process so that: ✔️ The right action is easy ✔️ The wrong action is difficult ✔️ Errors are detected early ✔️ Feedbac...

A mold designed with maintenance and disassembly in mind improves safety, reduces downtime, and protects precision components. At Star Moldes, we believe molds should include specific features that make maintenance easier and safer for technicians. 💡 Key design features: 🔧 Integrated lifting points / eyebolts: Allow safe handling of plates and components during removal and transport. 🔩 Extraction threads and jacking screws: Help separate plates and components in a controlled way, avoiding the use of improvised tools that may damage precision surfaces. 🧱 Guide systems and alignment elements: Guide pins, bushings, and alignment features ensure components return to their exact position after maintenance. 🛠 Clear access to fasteners: Properly positioned screws and service...
