▶️ At Star Moldes, some of our most memorable projects are the ones that push conventional boundaries.

🎬 A few years ago, we developed a prototype mold that required operating temperatures well above the norm, around 180 °C. The application involved injecting PA reinforced with 60% glass fiber, a demanding material that calls for exceptional thermal stability and process control.

At those temperatures, traditional water or oil thermoregulation systems posed a significant risk. Any leak inside the mold or machine area could become hazardous, potentially causing equipment damage, safety incidents, or production downtime.


👉 Our solution? Integrated electrical heating resistances.


⚙️ Why We Chose Heated Resistances

Electrical cartridge heaters allowed us to:


✅ Operate safely at high temperatures:

Eliminating the danger of pressurized fluid leaks at 180 °C


✅ Deliver precise, localized heating:

Critical for maintaining uniform cavity temperature with highly filled PA compounds


✅ Improve material flow:

Especially important for PA 60% GF


✅ Stabilize the process:

Consistent thermal conditions led to reliable prototyping results


✅ Enable faster setup and adjustments


✅ Increase durability in extreme conditions


🔎 Projects like this reflect what drives us at Star Moldes: combining engineering expertise with practical decision-making to solve complex molding challenges.

If your next project demands unconventional solutions, we’re ready to take it on.

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 – ...

Today's KNOWLEDGE Share : A BUG IN INJECTION MOLDING

Image
Today's KNOWLEDGE Share A bug in injection molding – an injection-molded part in a bug? Neither! Nature and injection molding have reached similar results. Nature created the first micro-gear long before any human engineering existed. One such example is the Issus coleoptratus (shown in the picture). Furthermore, only now are we reaching the point where injection-molded polymer microgears can approach this level of performance. Looking at the images, which one do you think is the natural gear, and which one is the molded version? It is not that easy to tell, right? Their appearance and operating principles are surprisingly similar. Chitin, a natural linear polymer, forms what nature essentially "molds” into shape. In engineering, we rely on advanced technical polymers to produce similar geometry through actual injection molding. They are not the same material, yet they solve the same issue: Stiffness, dimensional stability, and reliable function at a scale where tolerances...
