For decades, metal has been the standard for strength, durability, and safety in industrial applications. But today, reinforced thermoplastics offer a viable replacement in many fields—often improving overall product performance. So the question arises: does it still make sense to rely on metal?

LATI answers with two real-world case studies, where plastics don’t just match, but outperform.
Spark: the robotic stretcher that challenges steel
A medical device that transports up to 320 kg? Done.
Spark is a next-generation robotic stretcher designed to navigate rough terrain and carry patients safely. Its innovative design features independently adjustable legs to fit patient positioning.
At the core of the project is a critical component: the frame’s wheel support, subject to intense mechanical stress. Material used: LATAMID 66 H2 G/50 (PA66 reinforced with 50% glass fiber)
Performance comparable to metal
• Tensile strength: up to 220 MPa
• Elastic modulus: 16,000 MPa
• Dimensional stability: even in humid, high-temperature, and loaded environments
• Aesthetic finish and colorability: smooth and glossy surfaces despite reinforcement
FEM (Finite Element Method) simulations were run to optimize geometry and stress distribution. Injection molding challenges were addressed thanks to Capra Plast’s expertise, using high thermal conductivity steel to reduce cooling time and deformation.
Brave: lighting cities without aluminum
Brave is an urban LED floodlight, designed to withstand impact (IK09), UV rays, and corrosion. The main goal: eliminate aluminum while maintaining strong thermal and mechanical performance. Material used: LATICONTHER 62 GR/50 (PA6 with 50% graphite)
Functional advantages of the thermoplastic
• Thermal conductivity: up to 20 W/m•K
• Dimensional stability: on large parts (231×182 mm)
• Chemical and mechanical resistance: ideal for outdoor use
• Mechanical compatibility: perfect with self-tapping screws (e.g., EJOT Delta PT)
LATI’s long-term partner Vossloh Schwabe has developed expertise in designing and processing thermally conductive compounds. The precisely engineered Brave floodlight body is a result of this collaboration.
LATI thermoplastics vs metals: comparative benefits
| Feature | LATI thermoplastics |
| Weight | Lighter than metals |
| Sustainability | Lower GWP than aluminum |
| Corrosion resistance | Excellent in harsh environments |
| Processability | Ideal for integrating multiple functions |
Sustainability and circularity: measurable value
LATICONTHER 62 GR/50 has a lower GWP than aluminum—even in its recycled form.
Also available as chemically recycled (LATICONTHER 62 CR GR/50), it maintains its thermal conductivity while reducing environmental impact and ensuring traceability.
Smart materials for a more efficient industry
Metal-to-plastic replacement is no longer a design hypothesis—it’s a proven, winning strategy already used in demanding sectors such as medical, lighting, transport, and industry.
With LATI thermoplastics, companies can rely on lighter, stronger, more sustainable and easier-to-produce components—without compromising performance.
