Real production defects in plastics processing can tell us far more than appearance alone. I am looking for photos of defects in pipes, profiles, sheets, films and other extruded plastic products. In return, I will provide a short technical comment: possible causes, areas to check first and directions for further analysis. The most interesting cases may inspire neutral examples in my upcoming book “Plastic Extrusion. Pipes • Profiles • Sheets • Films”. Submitted photos will not be published, and no company names, production sites, customers or production data will be disclosed.

In pipe production, losses rarely start with one major failure. More often, they begin earlier: during start-up, changeover, raw material changes, unstable calibration, recurring downtime or decisions made without a shared technical standard. This article shows where money really leaks in PE and PP pipe production, why reports often reveal the problem too late, and how operators, technologists, maintenance teams, safety managers and executives can reduce hidden losses by building a common understanding of the process.

Choosing a polymer family is only the first step. In real plastics processing, the decisive question is which specific raw material fits the product, tool, machine, throughput and quality requirements. PP, PE, ABS, PA, PC, POM, PET, PBT, PVC, PMMA, PPS or PEEK can behave very differently depending on flow, shrinkage, fillers, stabilisation and processing conditions. This article explains why material substitution should always be checked against the real process, not only against a data sheet, because the lowest price per kilogram can still create higher long-term production costs.

A brittle bumper after a minor impact. A pipe damaged during installation. Unpredictable behavior at low temperatures.
These are real-world failures often linked to one key property: IMPACT RESISTANCE—the ability to absorb impact energy without brittle fracture.
This article explains where recycled plastics are used in vehicles, why safety depends on controlled impact resistance, and how PP and ABS regranulates should be tested. It covers Charpy vs. Izod, standard requirements, specimen preparation, and how impact resistance changes after recycling

In blown film extrusion, defects rarely originate where they become visible. Thickness variations, unstable frost line, or bubble instability are usually symptoms of earlier process imbalances. Cooling, inflation, haul-off, and material behavior form an interconnected system where every adjustment affects multiple parameters. Without understanding these dependencies, production falls into trial-and-error corrections. True stability comes from analyzing root causes, parameter trends, and process interactions rather than reacting to isolated symptoms.

By 2030, chemical recycling will become a key pillar of Europe’s circular economy. The importance of pyrolysis, hydrothermal liquefaction (HTL) and PET/PA depolymerisation will increase. The market will require standardised pyrolysis-oil quality and full integration with refineries. Regulatory duties will expand, covering mass balance, material audits and minimum recycled-content levels. Companies preparing early will gain a clear competitive advantage.

Why does a color sorter in plastic recycling sometimes reject good material or operate inconsistently? In many cases, the issue is not the machine itself but configuration and operating conditions. This article explains how plastic sorting really works, how compressed air affects selectivity, and what determines stable performance and production optimization in plastic recycling.

Chemical recycling succeeds or fails based on feedstock quality, not technology alone. It determines process stability, product quality, and profitability. Many companies wrongly assume that any waste stream is suitable, yet composition and variability can radically change outcomes. Feedstock assessment is a strategic first step and the foundation for any viable chemical-recycling project.

Purchasing a plastic processing or recycling machine is more than just a cost – it's a strategic investment decision. When the supplier is unknown and the stakes are high, experience makes the difference. At Rolbatch Laabs Engineering, we offer technical advisory services across Europe and Asia. We help verify suppliers, optimize machine configurations, and ensure CE compliance. Avoid risks. Make smart, informed decisions with our expert support.

Extrusion of glass-fiber reinforced PS isn’t just a processing task. It’s a layered design problem. Operators who grasp this become innovators—and their production becomes a competitive differentiator.
If you’re ready to shift from troubleshooting to strategizing, then your next step lies in deepening your team’s competence—not just buying new material.

Discover how the right technical knowledge helps your team prevent extrusion errors, reduce waste, and boost production stability. Each corrected parameter can save thousands of euros – and our courses show you exactly how.

The July 2025 EU act sets a new framework for chemical recycling.
It introduces mandatory mass balance, strict rules for allocating recycled content, external audits, and the “fuel-use excluded” principle. Regulations will expand to more sectors by 2030. Companies must ensure feedstock quality, documentation and compliance systems. Early adaptation creates competitive advantage.
