PVC is a notoriously demanding material. Its formulations often contain fillers, stabilizers, and additives that make processing both corrosive and abrasive. Wear manifests not only as dimensional loss and reduced output, but as higher energy consumption as machines work harder to maintain performance. Replacement-heavy strategies are increasingly incompatible with sustainability and budgetary goals. Rethinking component design changes that equation: - Advanced materials such as Nitralloy offer harder surfaces and improved wear resistance, eliminating chrome plating and extending service life - Worn conical twin barrels can be machined and restored using bimetallic treatments, pre...

As recycled content targets move closer to becoming a regulatory requirement in Europe, the automotive industry faces a growing challenge: increasing the use of post-consumer materials while maintaining the performance standards required for technical vehicle components. Headlamp housings represent one of the more demanding applications, where fogging performance, thermal stability, and long-term durability remain critical requirements. Developed by Sumika Polymer Compounds Europe, the new rPPGF Thermofil Circle Extra Low Fogging is designed to address these constraints. Response to future ELV requirements Made from European post-consumer recycled materials, the glass-fiber reinforced polypropylene compound meets the stringent requirements of headlamp housing applications, where fogging performance is a key criterion. The development comes as automotive manufacturers prepare for stricter recycled content requirements under future European regulations.   With this innovation, Sumika...

  Mitsui Chemicals, Inc. is expanding its lineup of bio-based hydrocarbon derivatives – including biomass chemicals and biomass plastics – under the #BePLAYERTM brand, as part of its efforts to promote the use of #biomass throughout society in order to help address climate change. #MitsuiChemicals’ biomass plastics based on the mass balance approach have now been adopted for various plastic parts used in #moldedtransformers compliant with 2026 Top Runner standards manufactured and sold by #Toshiba Industrial Products and Systems Corporation as well as for coils in extra-high-voltage molded transformers. Mitsui Chemicals is contributing to this initiative through the provision of raw materials as part of the supply chain*. This initiative represents a practical example of efforts aimed at achieving #carbonneutrality across the entire value chain, in line with Toshiba Group’s Environmental Future Vision 2050. In addition to addressing environmental considerations from a functi...

Unstable output. But by the time these issues appear, the real decisions are already behind us. And that’s why fixing them often feels rushed — and rarely solves the root cause. Problems Are Created Early, But Revealed Late Most injection molding projects don’t fail suddenly. They drift. Early on, everything looks acceptable: • trials pass • parts meet requirements • timelines move forward So decisions get locked in. But many risks are already present: • design margins with little room for variation • process windows validated under ideal conditions • assumptions that only hold at low volume Nothing breaks — yet. Production doesn’t create these weaknesses. It simply exposes them. The Place You See the Problem Is Of...
