But PE, PP and PET do not contain these chemicals as part of their polymer chemistry. Investigators should examine the entire converted package not just the resin. Potential downstream sources include: 🏷️ Thermal labels: Bisphenol or alternative color developers, dyes and binders 🩹 Adhesives: Tackifiers, stabilizers and residual formulation components 🎨 Inks and coatings: Pigments, solvents, binders and photo initiators Some thermal-label chemicals can migrate through thin packaging films under certain conditions. In recycling, poorly designed labels, inks and adhesives can also remain with the material or contaminate rec...

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...

At Star Moldes, we focus on: ✅ Rheological flow analysis (Moldflow simulation) to predict material behavior and optimize runner and gate design ✅ Geometrically balanced runner systems, ensuring equal flow path lengths and pressure drops ✅ Proper gate sizing and positioning to control shear rate and filling speed ✅ Controlled processing parameters, including injection speed profiling and packing pressure optimization ✅ Scientific molding validation, confirming real-world balance during trials 💯 In high-cavitation tools, even small imbalances in runner design, gate dimensions, or flow path geometry can lead to significant production inefficiencies. That’s why d...

The rubber boom of this period was very similar to the Internet bubble of the late 1990’s, including the resulting crash. Un-cured rubber goods had serious flaws. In the heat of summer, they became sticky and some deteriorated into a foul-smelling liquid. Cold weather robbed them of flexibility. The rubber market collapsed in the face of public disillusionment. The Roxbury India Rubber Company gave credit for twenty thousand dollars of defective materials in 1834. Being one of the largest and best capitalized companies, it was b...
