Quality Checkpoints in Plastic Production


In plastic manufacturing, quality isn’t just about the final inspection—it’s a continuous process built into every stage of production.


Here are a few key checkpoints engineers rely on:


✅ Shrinkage Control – Materials shrink as they cool. Understanding the behavior of each plastic type helps engineers predict and adjust for this.


✅ Surface Defect Detection – Flow lines, weld marks, or sink spots can indicate issues in mold design, temperature, or injection speed.


✅ Tolerance Measurement – Precision tools (like calipers or CMMs) ensure critical dimensions stay within spec—especially for parts that need to fit or move.


✅ Material Verification – Consistency in resin type, additives, and batch quality is essential for repeatability.


A good process is not just about catching defects—it’s about preventing them from the start, often beginning with proper DFM and mold design.


Understanding these checkpoints helps ensure reliable, high-performance parts—no matter the application.

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Image
Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Borealis’ new compounding line in Belgium offers premium recyclate-based polyolefins

Image
 Borealis is proud to announce that its new compounding line for recyclate-based polyolefins (rPO) is now fully operational in Beringen, Belgium. This milestone marks a significant step forward in helping customers meet their circularity and sustainability targets—without sacrificing performance and reliability. Using Borealis’ proprietary Borcycle M mechanical recycling technology, the line combines post-consumer and virgin polyolefins into rigid polypropylene (PP) and polyethylene (PE) compounds that meet the high standards required for demanding applications in mobility, consumer products, appliances, and energy. The Beringen facility is not only designed to process a wide range of recyclate flakes, offering exceptional versatility to meet diverse customer needs, but it also serves as a platform for collaboration—enabling customers to co-develop and test new solutions that bring recycled plastics into high-value applications. “This installation is more than just a technological ...
