💡 The Importance of Material Selection in Injection Molding


🔹 Material Selection: The Foundation of Flawless Injection Molding In injection molding, the right material choice isn't just a step—it's the cornerstone of performance, durability, and cost-efficiency. At SCSplastic, we know that selecting the optimal plastic can make or break your project, balancing factors like strength, heat resistance, and sustainability.


Why it matters:


- Ensures parts meet industry standards (e.g., ISO, UL).

- Minimizes defects like warping or cracking.

- Supports eco-friendly designs with recyclable options.


Below is a quick comparison of the top 20 common engineering plastics for injection molding, highlighting key properties like tensile strength, heat deflection temperature (HDT), and typical uses. This table is based on industry data from sources like DuPont, BASF, and Ensinger (2024-2025 benchmarks).


Pro Tip: For high-heat applications, go with PEEK or LCP. For cost-effective strength, PA66 or ABS shine.

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 “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...
